When should you obey the _________________ according to traffic, roadway, or weather conditions?

The basic speed law is an important principle that emphasizes driving at a speed that is reasonable and prudent based on the specific conditions present at the time. This means that drivers should adjust their speed according to various factors, including traffic flow, road conditions, and weather situations.

For example, if visibility is low due to fog or if roads are wet or icy, even if the posted speed limit is higher, the basic speed law dictates that you should drive at a speed that is safe for those conditions. This law is not just about adhering to maximum or minimum speed limits; it requires drivers to exercise judgment and ensure that their speed is reflective of the environment in which they are driving.

While maximum and minimum speed limits provide guidance on the extremes of speed, they do not account for various situations where adjustments are necessary for safety. Regulatory signs are important for providing directives but do not replace the fundamental requirement to adjust speeds based on current conditions as outlined by the basic speed law.
