Driving in snowy conditions can be tricky. It's not just about having a car that can handle the snow. Sometimes, the law says you need to put chains on your tires. This is to keep everyone safe on the road.
California's Rules
In California, the rules change based on how bad the weather is.
- R1 Sign: You need chains or snow tires on your drive wheels.
- R2 Sign: Most vehicles need chains, unless they have snow tires on all four wheels.
- R3 Sign: Everyone needs chains, no exceptions.
Consequences of Not Following the Rules
A trucker in Truckee found this out the hard way. They tried to drive over Donner Summit without chains. They got stuck and had to be towed. Plus, they got a fine that could be up to $500.
Colorado's Rules
It's not just California with these rules. Colorado has them too. There, the rules are called Level 1 and Level 2.
- Level 1: Some vehicles need chains.
- Level 2: All commercial vehicles need chains on all four drive tires.
Stay Safe on the Road
So, next time you're driving in the snow, remember: chains can save you from a lot of trouble. It's not just about avoiding a fine. It's about staying safe on the road.
