USAREUR Practice Exam

Which vehicles are permitted to proceed at an intersection controlled by hand signals?

1. Vehicle 1 only.

2. Vehicles 1 and 2 only.

3. Vehicles 2 and 3 only.

4. Vehicles 1, 2, and 3 only.

The correct answer is: Vehicles 2 and 3 only.

The correct answer indicates that vehicles 2 and 3 are the only ones permitted to proceed at the intersection controlled by hand signals. This suggests that, in the context provided, specific types of vehicles are designated to obey the hand signals while others may not be allowed to proceed. In situations where hand signals are directing traffic, it's important to recognize that certain vehicles might be exempt or required to follow different rules according to roadway regulations or the specific scenario at hand. If vehicles 1 were not permitted to proceed, it may indicate a restriction based on size, weight, or the type of operation that vehicle is conducting, which could include emergency services or larger trucks that require a different approach to navigating intersections. The situation could be supported by regulations that often prioritize certain vehicle types—like public transportation or military vehicles—when hand gestures are deployed, enhancing safety or ensuring operational efficiency in busy environments. Understanding the context and the operating environment of each vehicle is crucial to interpreting traffic signals effectively, especially in a controlled setting. Therefore, it's evident that vehicles 2 and 3 align with the necessary criteria to be allowed to continue, reflecting compliance with the established hand signals and traffic rules.
