Idaho Written Driver's License Practice Test

At an intersection with a non-functioning traffic signal, which vehicle has the right of way?

1. The vehicle on the right

2. The vehicle on the left

3. The first vehicle to arrive

4. The larger vehicle

The correct answer is: The vehicle on the right

In situations where a traffic signal is not functioning, the rules of right-of-way established by the Idaho Driver's Manual come into play. According to these rules, when two vehicles reach an intersection simultaneously and there is no operative traffic signal, the vehicle on the right has the right of way. This principle helps to reduce confusion and ensure safe navigation through an intersection when traffic controls are unavailable. It's important to understand that this rule is based on the idea of predictability and safety. By granting the right of way to the vehicle on the right, drivers can anticipate the flow of traffic and make better decisions on how to proceed, thereby minimizing the risk of accidents. Other factors, such as the size of vehicles or timings of arrival, do not supersede the right-of-way rules. Thus, the correct answer highlights the importance of following established right-of-way laws, even in unusual circumstances such as a traffic signal failure.
