Car Forum / Driving, Maintenance, Tuning / Driving / July 2009Slow Trucks 3 Miles Ahead
What do you suppose a sign reading "Slow Trucks 3 Miles Ahead" really means? Based on where I saw the sign and the road configuration, it most assuredly does not mean that if you go 3 miles beyond the sign you will find numerous slow trucks. Instead it means SLOW TRUCKS NEXT 2 MILES; the crest of the hill is about 2 miles beyond the sign, at which point trucks resume normal cruising speed. So, where is all this nonsense? Southbound US-101 in Calabasas, CA. The sign is at the Las Virgenes Road bridge (MP 31.05); the crest of the hill is near the Mureau Road bridge (MP 29.06). If there really were slow trucks 3 miles after the sign, wouldn't it be appropriate to repeat the warning closer to the slow truck area? >What do you suppose a sign reading "Slow Trucks 3 Miles Ahead" really >means?

That would depend on the grade of the downhill side. Like at Grapevine, the speed limit for trucks is/was 30mph. So in some cases one might run across a slow truck going down the hill. Specially one with a wide load and extra heavy. > On Mon, 27 Jul 2009 19:43:08 -0700 (PDT), larry_scholnick > [quoted text clipped - 23 lines] > > - Show quoted text - Correction - the speed limit for trucks is 45 MPH on the milder grade near Fort Tejon, and 35 MPH on the steeper grade approaching the town of Grapevine, CA. There is no need to specifically warn cars of slow trucks on I-5; the greater need is to slow the trucks down so that they don't need to use any of the gravel-filled escape ramps; I would assume that car drivers who see the numerous truck speed limit signs have been implicitly warned about slow trucks. On southbound US-101, the downhill grade from the crest of the hill in Calabasas to the valley floor less than a mile later is so mild that there are no speed warning signs for the trucks! > Correction - the speed limit for trucks is 45 MPH on the milder grade > near Fort Tejon, and 35 MPH on the steeper grade approaching the town [quoted text clipped - 5 lines] > who see the numerous truck speed limit signs have been implicitly > warned about slow trucks. As I recall, there is a "Trucks Only" (which usually speeding 4-wheelers in it) on those grades. > On southbound US-101, the downhill grade from the crest of the hill in > Calabasas to the valley floor less than a mile later is so mild that > there are no speed warning signs for the trucks! I almost lost a 57 Chevy pulling a trailer-with-hitch-brake going down that hill. Also used to service a repeater station south of the highway off the last exit before the bottom, driving a grossly underpowered Ford Econoline. (I got on going down-hill, then U-turned at the bottom because there was no way to get that Econoline up-to-speed in front of a truck that hit the bottom at the redline.

Yeah, "northbound-feels-like-west-bound". I drove a stick-shift 1946 Chevy (or maybe I had a Corvair, by then---yeah, I'd have towed a trailer behind my own '46 instead of my Dad's '57) and wasn't used to a two-speed PowerSlide. Got to going too-fast, tried to slow down--over-running-hitch slammed on the trailer brakes, I had to speed up to get it back in line. I saw a car behind me pull into the middle, block both lanes (only two then, so pulled into the middle too and stopped the combination, one way or another as long as it wasn't over the edge if I had any say-so. Developed an intense dislike for that kind of brake arrangement that I have not gotten over yet--and that was near 50 years ago.

No, the Conejo Grade is US-101 between Camarillo and Thousand Oaks (milepost 50 to 48). The grade I've been discussing is the Calabasas Grade (milepost 31 to 29). >>>>>> On southbound US-101, the downhill grade from the crest of the hill in >>>>>> Calabasas to the valley floor less than a mile later is so mild that [quoted text clipped - 10 lines] > (milepost 50 to 48). The grade I've been discussing is the Calabasas > Grade (milepost 31 to 29). OK--we were not talking about the same thing--the TO to Oxnard AFB (What's there now, beans?) is the grade I was talking about. There was a quarry south of the freeway, and we had a repeater station up the canyon from the quarry.
