Does a posted speed limit of 55 mph mean that you may drive 55 mph on that highway under all conditions?
A. Yes. You should always follow the speed limit under all conditions. B. No. 60 mph is a better highway speed than 55 mph. C. No. Speed Must be adjusted to conditions in order to avoid accidents. D. Yes. If the weather conditions were bad, you Must maintain your speed to find shelter.
The correct answer to this question is C. The posted limit is the maximum speed allowed under the best possible conditions. If a road is wet, icy, or otherwise impeded by lack of visibility or other obstructions, it is necessary to drive more slowly to match the conditions and maintain an appropriate level of safety.
Drivers must also be aware of additional potential hazards such as sharp turns, wildlife crossings, debris in the road, the appearance and actions of other vehicles, and other possible risks. Drivers must be cautious and aware of their surroundings in order to adjust their speed when needed.
