School Bus CHP Practice Test

If a school bus driver encounters fog or rain, what should they do according to the Basic Speed Law?

1. Slow to a safe speed

2. Maintain the posted speed limit

3. Maintain the same speed to avoid being rear-ended

4. Activate the four-way flashers and continue with traffic flow

The correct answer is: Slow to a safe speed

The Basic Speed Law states that drivers must never drive faster than is safe for current conditions, regardless of the posted speed limit. In conditions such as fog or rain, visibility and road traction can significantly decrease, creating a greater potential for accidents. Therefore, it is crucial for a school bus driver to slow down to a safe speed that aligns with the reduced visibility and increased stopping distance required on wet or foggy roads. This adjustment in speed not only ensures the driver's safety but also protects the passengers and other road users. By driving at a safe speed, the driver is better equipped to respond to sudden changes in traffic or obstacles that may arise due to the adverse weather conditions. Maintaining the posted speed limit during such situations could lead to hazardous driving conditions, contributing to an increased risk of collisions.
