-
- Hmm. I'd imagine that TC is talking specifically about the "chain
- controls" imposed by the California Highway Patrol, in cahoots with
- Caltrans, on certain mountain highways when winter storms are in
- the offing. This is especially noticeable on US 50 and I-80, the
- main conduits from the Bay Area to the Reno/Lake Tahoe area).
-
- I know a lot of experienced winter drivers who think they're a
- bunch of weenies who impose chain requirements at the least provocation.
- However, there are some other factors:
-
- * There is a LOT of traffic through those corridors because of the
- ski areas and the Nevada-side sin palaces. If one idiot wads up
- his car in a particularly obstructive fashion, you can get a
- traffic jam that *feels* like it extends from Sacramento to Winnemucca.
-
- * The weather up there can get very, very bad, and it's hard to say
- beforehand whether you're going to have a routine snowstorm or a
- massive blizzard. People have died up there before, and will again.
- It's a good idea to make sure that everybody has the wherewithal to
- maintain forward progress -- and to avoid accidents that would bring
- a lot of traffic to a lengthy halt during life-threatening weather.
-
- * Everybody seems to think that he or she is a good winter driver but
- none of those other idiots out there have a clue. :)

-
- I'm not sure about that. Caveat lector -- I'm not quoting the Vehicle
- Code on this -- but I usually see the requirements described as "chains
- required, 4WD with snow tires OK." I suspect that the CHP officer on
- the scene is the arbiter plenipotentary and extraordinary of who goes
- and who gets turned back, and that the ones stationed in snow country
- have a pretty good notion of what competent snow tires look like.
-
- TC>> furthermore, if you have chains, you can't go more than 30 mph.
-
- JF> That would depend a lot on the design of the chains, but if you need
- JF> chains you probably shouldn't be going more than 30 anyway.
-
- You can sure tell the difference between people who have cheap chains
- for occasional use (~ 30 mph) and those who have well-fitted chains
- (they venture as high as 45 or 50 when conditions permit). The main
- disincentive is the roughness and noise and general seat-of-the-pants
- impression that something is dreadfully wrong with the underneath of
- your car when you use the el-cheapos. Some people say that one of the
- main purposes of the chain controls is to slow people down, both to
- meter the volume of traffic and to keep the idiots from tugging too
- hard on Father Darwin's beard.
-
- But the Sierras (and several of California's other pointed topographic
- features) are real mountains with real winter storms, and there are
- occasions when the chains are useful for traction.
-
- Happy motoring,
