What does the basic speed law require drivers to do?

The basic speed law requires drivers to adjust their speed according to road conditions to ensure safety. This means if driving at the posted speed limit is unsafe due to factors such as poor weather conditions, heavy traffic, or road hazards, a driver must slow down. The law emphasizes that speed limits are not absolute; they are guidelines that take safety into account. Thus, a driver has the responsibility to drive safely and considerately, adjusting their speed as necessary based on the environment and circumstances they encounter while driving.
