Nevada Class C Driver's Practice Test

A yellow arrow serves as an important traffic signal that provides drivers with critical information regarding changing conditions at intersections. The primary purpose of a yellow arrow is to alert drivers that the signal is about to change, thus requiring them to be prepared for a stop or to make a decision about how to proceed.

The yellow arrow indicates that the light will soon turn red, signaling that drivers should be ready to either stop for a potential turn or to clear the intersection. It suggests that the driver must be alert and prepared for an upcoming change in the traffic signal, supporting safe and effective decision-making.

Since the yellow arrow does not suggest that drivers should maintain their current speed, it indicates that the situation is changing and requires attention. This is why the indication to maintain speed is not aligned with the purpose of a yellow arrow. By understanding this, drivers can respond appropriately to the changes in traffic signals, ultimately promoting road safety.
