That's a good question. One reason why I don't use such a signal period.
That way, hopefully, my non-signal tells the other driver that yes, I
have ROW, yes, I know it and yes, I am going to proceed in accordance
with traffic law.

Not too sure of the legality of the signal either. IIRC from my GA
drivers manual (from several years back), there was a section called
"illegal signals," in which, flashing headlights was one of them. One of
these days, I'll have to look at a more current one and see if that
still holds true. And of course, for other States, YMMV.

Some states have a law specifically prohibiting flashing lights
as a "do pass" signal.  I don't know whether that is intended to
apply only to signals to cars approaching from behind.

In some states -- not all -- flashing high beams is illegal as
a general rule.

Because of its universal meaning of "Speed trap ahead".

some states also consider flashing headlights as a warning for radar traps
to be illegal.(not that that makes any difference to me)

Why would you flash your headlights at a car trying to make a left turn
in the first place?  Is that standard driving practice where you live?
If not, I guess it's open for interpretation.

Yes, there are other meanings -- "turn off your brights," for one, or
"turn your lights on." But in the context presented, I think the most
common interpretation would be "go ahead."

Of course, this is all the more reason not to use such a signal for
anything critical in the first place (such as telling someone whether
or not to drive in front of your moving vehicle).

and "please get the hell out of the passing lane unless you're about to
pass."

the only "go ahead" headlight signal I can think of would be in a
passing situation where you let a large vehicle know that he's clear of
your front bumper - during the day, a flash of the lights, or at night,
a quick shutoff of the lights.

Personally, if someone were flashing headlights at me during the day
I'm not sure how I'd interpret it.  It seems that at least in the US
there are very few universally understood light signals; even the
"you're clear of my front" only truckers seem to get.

I suspect this is where the use for turns came from.  You can extrapolate the "you're clear of my front" to "you're clear to go".  

Speaking of cluelessness, I was driving with someone in the middle lane of the Jersey turnpike who did not understand why trucks might be coming up behind them and flashing their lights (the right lane was packed).

Because for instance I'm trying to tell them "there is no need to force

Or........I can see a whole lot of stopped or very slow cars ahead of
me so I can slow down and let you turn in front of me without causing
me to lose any  time whatsoever in my journey.

There is no need to flash. Stopping and possibly a hand motion will do
without any confusion.

There's no need to do lots of things that we do, but that doesn't stop
us from doing them

But much less efficiently than flashing your lights

It seems to work in the regions where I drive so all the nit-picking
about whether it's universal or not is just that, nit-picking.

Accordingly, for instance they can also interpret this as "Go ahead,

Well,there aren't any STANDARDS for this,nor any organization to create
them.

Just think of it as trying to make them aware of you,or them making YOU
aware of them(INSURING awareness,not taking a chance).

You would do so to warn them so the car aimed in the direction you're
coming from not to turn left (crossing your line of travel) until
after you've passed. Their failure to yield ROW might result in a
t-bone if the person who's ROW is being usurped isn't responsive
enough to avoid the situation.

I don't think it's a standard driving practice anywhere; flashing the
headlights, that is. I know taking ROW is standard driving practice
where I live, which is why I chuckle just about every time I read of
another local dullard who uses their car to commit suicide.

1) that doesn't mean part of it isn't rural.

2) Massachusetts is also totally subdivided into municipalities, and I think at
least some of the other New England states are as well.

I believe it's also true in Massachusetts and Rhode Island.

Huh? What does the type of municipality have to do with whether an area
is rural or suburban or urban?  All of Pennsylvania is comprised of
incorporated cities, borought, townships, and a town, but you'd be
hard-pressed to say that there are no rural areas in Pennsylvania. Same
with New Jersey, Connecticut, etc.  You seem to have your terms confused
here.

So you don't know Massachusettts? Every square inch is part of
one (and unlike Connecticut, ONLY one) municipal corporations.
What that has to do with being "rural" is another question ...

I would do that just to get their attention,perhaps so they would not make
that turn right in front of me when they should not (because I'm too close
or moving faster than they estimate.)

IOW,a precaution.

Here (in Florida) someone just did it to me the other day - flashed,
slowed down, and gave me room to turn.

It's also pretty common where I live, in a stretch bereft of
crosswalks, for people to do this to indicate he/she is letting a
pedestrian cross.

It is standard driving practice in New England.  It is also used to
signal to pedestrians that they can cross in front of you.

After moving South, I quickly realized that it is not standard down
here, judging by the blank looks on many peoples faces.

I don't know, who was it that decided that green means "go"?  Flashing
one's lights has been pretty universally understood to mean "go ahead"
as long as I can remember, whether for letting someone turn in front of
you, or for changing lanes on highways. You must be having a lot of
near-misses or awkward pauses with this misunderstanding.

The only exception I can think of is when tailgating someone you'd like
to move.  Honking one's horn is generally the way to go if you've got
something urgent to express.

Flashing lights universally means "train is coming" or "emergency
vehicle is coming." And when someone puts their blinkers on they are not
saying "I'm letting you pass me."
Pete from Boston - 23 May 2006 18:53 GMT
We're all clear that we're talking about headlights here. There's no
need to get cute with comments about blinkers. Yes, I know what my
exact words were.

There's also no need to start pulling in situations that are not in the
context you described -- an oncoming vehicle turning across your
right-of-way -- such as "train is coming." Incidentally, in what
situation does a car flash its headlights to announce to other cars
that a train is coming? That's one I've never encountered.

You go out there in Massachusetts and do some testing -- flash your
headlights at oncoming cars waiting to turn left in front of you, and
see how many interpret it as "go ahead." You'll probably end up with
lots of insurance money, but you'll probably also realize people more
often than not interpret it in that situation as "go ahead."

My point was flashing lights one encounters while driving generally mean
"caution," for instance at RR crossings or at construction sites. If a
car is coming towards me at night and I flash my lights at him, I am not
trying to say "drive any way you feel like." I saying "watch out, I'm
over here!"

Why would the same scenario be any different in daylight?
223rem - 23 May 2006 23:54 GMT
As you've been repeatedly told, it is wrong to flash your high beams as
you described.
I assume that the reason you asked is that you wanted to learn, and not
to argue.

If you'll ever drive in a big city like Chicago or Toronto or NYC,
you'll find that people use the horn (brief, repeated honks) when going
through intersections  to let drivers without the right of way that
they're to stop.

Local customs ... I've never seen what you describe there. OTOH,
flashing your lights in a give-way situation is universally understood
to mean that the flasher is yielding ROW. There is never any
confusion between this and other uses of headlights (eg. to warn
of a hazard).

Evidently there IS much confusion as to what flashing headlights means,and
that they might mean different things depending on the situation.

Meaning to me that I should not consider them anything but an alert,to pay
attention for something unknown to me ahead,and to rely on my own
judgement,not anyone elses.

I don't agree with you very often, but here I do... so I will.

But it depends on the flash.  A rapid 3-5x+ flash probably means "look
out".  Slower flashes x2 (or 1 long) mean "I yield to you" and convey
no sense of urgency.  The regular ol' 3x flash means "C-O-P ahead".

I don't know how "universal" the understanding of light flashing is
today, most drivers are not focused much on other traffic, other than
how to get past it.  Back in "the olden days" courtesy used to be
fairly common.  It still doesn't cost anything to be courteous but most
drivers are so self absorbed they more rarely consider helping out
another driver.

People use a few quick flashes in my experience to cede the
right-of-way. Usually one slow flash from an oncoming car means "cop
ahead," or "turn off your brights." If an oncimng car's headlights are
off altogether I usually quickly turn mine fully off then on again.

Because signaling other drivers by flashing your lights is atypical
behavior.

You don't drive around in daylight (or dark) flashing your lights all
the time to tell other drivers "I'M HERE, I HAVE THE RIGHT-OF-WAY, SO
WATCH OUT FOR ME!"  nor do you see other drivers doing so.

So... flashing your lights is not interpreted to mean that, so it must
mean something else.

Now, it could mean a lot of things, depending on the situation.  When a
driver is waiting to make a turn across your path it means "I see you
and will adjust my path or velocity as a courtesy to you so that you
may proceed".

Sheesh...

Indeed.  Maybe a dozen years ago I read in a motorcyclist magazine
(note that motorcycles generally have the headlight on at all times)
that the author of the letter had seen these headlight modulators that
are supposed to make the motorcycle even more visible to drivers,
not having one he decided to make sure the left-turning driver
oncoming to him saw him, so he started flashing his headlight to
make sure, and said driver smiled, waved, and cut him off.  The
author realized his error, and advised other readers not to confuse
manual flashing with built-in modulation.

I _do_ use my car headlights if (due to construction or passing) I
find myself to the left of the yellow lane, but not high beams and
not flashing.

Flashing high beams can mean other things in other contexts, like
"Would you be so kind as to yield the left lane so that I may
pass you" or "Pardon me, but you seem to have forgotten to dim
your own high beams even though there is oncoming traffic, namely
me, being blinded by them" or "Look out, there's a speed trap
ahead in your direction that I've just passed".  But in the situation
where another driver is attempting to change into your lane in front
of you, or to cross your lane, it means "I yield".

ummmm, that's what your regular headlights are for, genius! It really is
not necessary to flash your lights at oncoming traffic like that unless
they have their lights off, brights on, or they're making a beeline for
your front grill.

My point is, I think you're expecting too much by questioning the
logical inconsistency when comparing this use to other lights that
happen to flash. Flashing a light is just an attention-getter. The
reason for the attempted attention-getting depends on the context. Like
a dog barking. The dog may bark whether it's happy to see you or angry,
because that's most of its ability to vocalize, but you use the other
available cues to know which it is.

I think you've got it exact. Context is everything.

I see this almost every day at the turn off to
my daughters HS. This is off a two lane road which at 7:10AM
is pretty busy in both directions, about half the cars
doing dropoffs, and half commuters going straight through
(mostly eastbound).

If you're approaching weatbound, you have
to turn left across eastbound traffic to get into the
schools driveway. Westbound traffic backs up
considerably waiting for a chance to turn.

It's almost a given that some of the eastbound traffic will
yield ROW, and will indicate that they are doing so by flashing
or waving.

If you've decided to yield, indicating that you are doing so
saves everyone time, since the crossing traffic can get underway
sooner.

Why is there ANY NEED to alert others to whether a train is coming?
Aren't there already flashing lights at the crossing?? And if no lights are
at the crossing,it's -their- responsibilty for stopping and CHECKING before
crossing.(it IS -their- butt on the line,not yours,nor would I depend on
others for checking for me)

I understand that truckers would flash their headlights when a passing
vehicle had gotten far enough ahead to make a safe merge back into the
trucker's lane.

And flashing headlights at an oncoming vehicle -generally- means to dim
your highbeams.
But flashing the headlights can be used for just getting an approaching
vehicle's attention,especially at night.
They also may not be able to determine who a horn toot came from,or even
HEAR it with today's loud stereos and noisy performance mufflers.
People today are oblivious to even emergency vehicles sirens and flashing
lights.

That's crap.  For example, when I learned to drive I was taught that if you
are the first to flash your lights at a one way bridge, you have the right of
way over the driver going the other way.
Some car makers have a momentary high beam flash function, they call the
feature as "flash to pass" or "optical horn."

If I saw that signal, I would interpret it as "you forgot to turn on your
headlights" or "one of your lights is burned out."

Let me guess, you also slow down when you do that?

Your hesitation and unnecessary high beam signalling  will
only invite the other driver to turn in front of you.

Maybe it is a regional habit, but within the Northeast, slowing down
and giving a quick flash of the high beams certainly seems to be a
universal signal to another driver that they may make a turn or
otherwise proceed in front of you.  I say this having learned to drive
in the Boston area two decades ago and as a resident of Upstate New
York for the past 10 years.

The idea that the originator of this thread and others are flashing
this signal and meaning 'Don't go - I'm not stopping!' is scary.

NO one should depend on an approaching vehicle's flashing headlights as any
kind of permission to do whatever they intend on doing.

It's the *driver's* responsibility to check and make the proper decision
whether it's safe to do any driving maneuver;before acting. Nobody else's.

I grew up driving in NY and VA, and learned that as well.  I always
understood it to be a trucker signal; the pass-ee flashes his high beams
twice to signal "go ahead, get in front of me", and the pass-er taps his
brake lights twice after the pass to signal "thanks".  I've always got the
acknowledgement back from truckers.

Since trucks are the big heavy things on the road, I think that whatever
they say goes.

I agree.  When I first moved to MA, I used to get intimidated by folks
slowly edging out of a side street.  I used to slow down slightly, and
then they would pull out right in front of me, causing me to have to jam
on my brakes.  I used to think MA drivers were nuts.

Now I know better.  If you flinch, they will take advantage of you.  If,
on the other hand, you proceed normally, they will seldom cut you off.

Same thing with folks slowly edging into your lane to make a left turn in
front of you.  If you flinch, they will often bang a left.  If proceed
normally, or if you edge to the left, towards them, they will stay put.

Its just a matter of knowing the local, unwritten rules of the road.  If
you flinch here, you will get cut off.

Same thing with red lights.  Here, folks go through the yellow, even if it
means that they will be in the intersection after it has turned red.  In
NYC, folks jump the green, even if it means that they cross the stop line
while the light is still "slightly" red.  Either system works just fine,
but if two drivers are using different unwritten rules at the same
intersection at the same time, then CRASH.

IMO, those NY dirivers are NUTS!!  :)

I've found here folks here are plenty willing to yield the right of
way,
such as that left turn situation (such as through an unsignalized
intersection, facing stopped traffic) and strangely when I'm at
a stop sign (T-intersection) waiting to make a left, the operator
of the car making a left onto my street yields to me.  And often
by using the "Warning: There is a train coming" feature of his
headlight control.  My new-to-me van has that: if I want to signal
that a train is coming I pull the turn signal stalk.

I figure it comes from the signal well understood by truckers,
and it generally means "I see you and I am yielding to you".
(A horn toot may be used, but horns are usually signifying
anger, except the shortest of toots accompanied by a
waving gesture.)  Depending on the light it can be hard to
see the other driver's gestures.

If I'm turning left and the oncomng driver doesn't see me
I have to assume he is NOT yielding the right of way, so
when he is telling me that he sees me he is either proactively
warning me that even though he has a last clear chance to
avoid an accident he won't, or he is yielding.

Of course.  If someone is waiting, and you can easily yield the right of
way to him (maybe by slowing down a fraction, giving him a chance to turn)
it is courteous to do so.

And IMO, when it is raining, pedestrians have the right of way, no matter
what.  

But when someone is obnoxiously edging out, trying to intimidate you into
flinching momentarily, they do NOT get any breaks. Indeed, they sometimes
get me to pretend to look at my passenger, all the while veering towards
them and speeding up (not really...:).

Them is MY rules.  And I stick to them.  Usually with a little hand
gesture, or a nod of the chin.  But a flash of the headlights would work
just as well, I suppose.

Does your vehicle manual label this stalk as such?
If so, can you scan that page and post it somewhere? I've *never* seen
this stalk so labeled.
In fact, *every* RR grade crossing I've ever seen is, at the very
minimum, labeled with a RR Crossing sign, and most have active lights,
and many have barriers, too.
Given that, why would it be incumbant on a driver to warn other
drivers of coming trains? Wouldn't that mean that those who don't give
such warnings would be liable in case the unwarned car collides with a
train?
And why is such a "universal" sugnal not covered in any driving
manuals, or laws?

I am baffled by the people in Boston who will yield right of way
when it's completely stupid for them to do so. I especially hate it
when I'm trying to cross a four-lane road (say Columbus Avenue) and
I'm at the corner, and someone in the left lane stops to let me cross
the road. I'm like -- well, all I need is some yahoo to come zipping
around them in the right lane and I'm toast, so I don't take them
up on the offer, and they move their hand and I just don't move.
Finally someone honks behind them and they move.

This city is full of drivers who either grab the right of way when it's
not theirs to grab, or give it away when ever possible? It's completely
alien and bizarre.

Reminds me of the joke:

"Once I was riding in a cab in New York City when the driver ran a red
light. I asked him, `Do you realize you just ran a red light?' The
driver said, `Relax. My brother drives like this.' The driver ran
another red light, and turned to me and said, `Relax. My brother drives
like this.'

"Thank goodness the next light was green, but the driver came to a
screeching halt. I yelled, `You ran two red lights saying your brother
drives like that, then you come to a green light and stop! What's up
with that?' The driver said, `Well, I have to stop at green lights,
because my brother might be coming down a side street.'"

Actually, that's been a convention for as long as I remember (at least
20 years). Your horn is there for a reason. Use it. If you flash your
lights, most people take that to mean you are yielding your right of way.

If you would get your head out of your butt, or perhaps get your

of Americans killed/maimed COULD have avoided their circumstances. That
they choose not to do so is not my problem, and it's enjoyable reading

I know it's illegal for non-law enforcement officers to possess blue
lights in their car, but how about a PA system that will broadcast the

I have driven all over this country and Canada except Alaska and I have
never run into a situation, other than a warning that your headlights
are not on or there are police ahead, that flashing of headlights did
not mean that the flasher was relinquishing their right-of-way.

I have also read of instances where by flashing your lights, you are
taking responsibility for the situation.  For example, if you are in
the inside lane of a four lane road and you flash your lights for
someone to turn in front of you and they subsequently crash into a car
passing you on your right, you can be partially responsible for the
accident.  (I can't cite any specific example off hand.)

There have been court cases where a driver has been held liable after
stopping and waving a pedestrian across an intersection where the
pedestrian is hit by another car. I'd think a driver flashing his
headlights would be similarly culpable.

I don't believe that at all;how would anyone establish exactly what you
were flashing your lights for?

Personally,I would never count on another's flashing lights as "permission"
to do anything.

I would just consider them an alert;to pay attention,there might be
something I NEED to consider.

Anything else would be foolish.

From a family member's crash several years ago, I can categorically
say that, in AZ., that last is not true.
It is, by law, incumbant on a driver making a left turn to ensure that
it is safe to make the turn, regardless of other drivers'
well-intentioned signals.
That well-intentioned driver should be ignored, if you can't see
what's coming.

Massachusetts prefers the "deep pockets" approach to liability,
where the jury gets to decide who pays in almost all cases.
So the insurance company of the driver who stopped to let a
pedestrian cross illegally paid a seven figure settlement
after the pedestrian was hit by another car.  In many states
you lose the lawsuit pretty much automatically if you break

IIUC it is illegal to pass a car that has stopped to allow
a pedestrian to cross (when said pedestrian has ROW?
when it is legal for said pedestrian to cross? -- and I don't
know how the driver is supposed to know why the other
driver stopped) -- was that the case when this case

In Massachusetts that law only applies at marked crosswalks.
There was no crosswalk.  One driver stopped to let the girl
cross.  Somebody passed him, I think using the right lane of
a four lane road, and hit her.

GRRRRRR!!!!!!! I hate a**holes like you who do that! Very annoying!
Whenever I get flashed like that, I usually flash my lights right back
and flip 'em the bird!

Some people do an extra long flash, thereby blinding me for a second or
two if done at night. Idiots!!! If someone needs to be flashed to remind
them not to cut another one off, then they shouldn't be driving in the
first damn place! GRRRRRR!!!!!!!
jwardell - 24 May 2006 21:21 GMT
Great topic.
I see this all the time. Several times per week. I may have even
followed along and done it myself in the past, however lately I've been
concentrating on not flashing high beams.
If my normal lights are already on, I may turn them off and back on
quickly to signal a positive (go-ahead) signal.

The confusion here I think is that in europe flashing lights is very
commonly used, and always means warning. I remember the first time
watching Ronin and seeing all the flashes in the tunnel chase seemed
weird to me. Now I understand they are used all the time as a warning.
For example, when you are coming up on someone on the autobahn in the
left lane so they get out of your way well ahead of time.

Of course in the US, the same flash is often used to get someone out of
rubbernecking the left passing lane, but they will either move over,
ignore you completely, or most likely take it personally and start some
road warfare...which is why I never flash my high beams when I want to
pass someone sitting in the left lane!

This just occured last night when I was driving on Rt. 3. A focus was
doing a medium speed but never left the left lane, despite light
traffic. A big SUV wanted to pass, and after the focus did not yield
after the SUV was at most 2 feet from its bumper for a while, he
flashed his lights several times. The focus didn't budge. (Now, you
potentially have two ticked off road ragers). Meanwhile, I peacefully
and slowly passed in the right lane.

Of course, in Connecticut, that is illegal, because their law assumes
everyone will always stay right. In a perfect world...

Î was reminded of this topic with a smile yesterday. When trying to

A flashing headlight has no legal meaning.  That is why some folks take it
to mean different things.  That is also why you shouldn't use it as a
signal that means anything other than look here.
