USAREUR Practice Exam

In the presence of a police officer controlling traffic, which signals should drivers adhere to?

1. The police officer's signals.

2. The traffic light's signals.

3. Both signals equally.

4. Neither, as they cancel each other out.

The correct answer is: The police officer's signals.

Drivers should adhere to the police officer's signals in situations where a police officer is controlling traffic. This is because the police officer has the authority to direct traffic and ensure safety on the road, especially in scenarios where standard traffic signals may be malfunctioning or where the traffic conditions require immediate intervention. The officer's instructions take precedence over traffic lights to guide drivers effectively based on current circumstances. While respecting traffic signals is crucial under normal circumstances, the presence of a police officer indicates that they are managing the situation directly, often for safety reasons and to prevent accidents or congestion. Thus, following the officer's signals is essential for compliance and for the safety of all road users. In contrast, adhering to both signals equally is not practical in this context. The same goes for disregarding both, as it could lead to confusion and potential accidents. The hierarchy of authority dictates that the officer’s commands are paramount when present.
