What is the minimum speed at which a vehicle can be driven on all California highways?

30 mph
40 mph
50 mph
55 mph

The correct answer is: 55 mph

The minimum speed at which a vehicle can be driven on all California highways is 55 mph. This is the maximum speed limit for most highways in California and it is important to maintain this speed for the safety of yourself and others on the road. Options A, B, and C are incorrect because they are lower than the minimum speed limit and would not be safe to drive on the highways. Driving too slowly can also cause traffic congestion and increase the risk of accidents. While it is important to follow the speed limit, it is also important to use common sense and adjust your speed according to traffic and weather conditions.
