Driving too slow.
|

Explanation
California’s “Basic Speed Law” means that regardless of the posted speed limit, your speed should depend on the current road and weather conditions. Never drive faster than is safe for current conditions. For example, the posted speed limit on a slippery or fogged-in roadway might be 55 mph, but the safe speed to drive would be much lower.
