Probably has to do with the almost non-existent skill level of California drivers and snow. If chain control is in effect, they have been known to go through parking lots at the ski slopes and ticket the cars without chains, lest you made it in through a side road and didn't chain up.
Not CHP, caltrans. I will speak based on tahoe knowledge.
They use the CHP just if they need help do a traffic break when they are putting up controls.
This is not just because they like to have fun with CA drivers. If you spin out, then the whole road is closed and takes a lot of time to get a tow truck up to open things up. The reason for it is 80 and 50 are part of the national highway defense system so they are mandated by that designation to take measures to ensure these roads are not going to be closed.
If the russkies attack, (Red Dawn) we need these roads open to move our troops to save those high school students.
Chains easily found (if you are travelling when stores are open), but just check the weather and road conditions before you go. You are better off knowing and practicing how to put them on before you go. But if you're not going to practice, and this is a 1-time thing, the availability of chains actually better the closer you get to the mountain foothills-so you can just make the on-the-spot decision say in sacramento that you need to make a stop somewhere get chains. They will have Highway Displays telling you if chains are going to be required on the drive up.
Of course, this is all dependent if it's ever going to snow again in tahoe
.
Check weather for tahoe, check road conditions, if there is no forecast of any snow for the length of the just go up.
If there is a forecast for snow, get chains.
Bring cash. If you do not know how to put on chains or cannot figure out how to do it, and it's dumping, there are chain installers who can help you (for pay). The prices are steep though, it will be around $45 on, $35 off. It is a set price and organized by caltrans so you don't need to price shop. They are working with a permit.
