USAREUR Practice Exam

Under what circumstances must minimum speed limits be obeyed?

1. Always, without exceptions

2. Except when road conditions are poor

3. Except when visibility is low

4. Both B and C

The correct answer is: Both B and C

Minimum speed limits are established to promote safe and efficient flow of traffic. In situations where road conditions are poor, such as during heavy rain, snow, or ice, it may be unsafe to maintain the minimum speed limit because vehicles may struggle to maintain traction or control. Thus, drivers are allowed to travel below the minimum speed limit under these circumstances to ensure safety. Similarly, when visibility is low, such as during fog or heavy rain, adhering to a minimum speed limit might lead to dangerous driving situations. Reduced visibility can require drivers to slow down considerably to maintain a safe stopping distance and react to any unexpected hazards. Hence, in conditions where visibility is compromised, it is safer to travel below the minimum speed limit. Therefore, the correct understanding is that minimum speed limits must be obeyed, except when road conditions are poor or visibility is low, making options B and C valid exceptions that combine to provide a comprehensive view of driving safety under varying circumstances. This is why acknowledging both conditions as exceptions is essential for ensuring overall traffic safety.
