If a traffic light shows both a red light and a green arrow, what is true about turning in the direction of the arrow?

The correct choice indicates that a driver must wait for the red light to change before turning. This aligns with traffic rules that require drivers to adhere to the signals of a traffic light. In this situation, the presence of a red light means that vehicles must stop, even if there is a green arrow indicating that a turn could potentially be made in the direction of that arrow.

When a green arrow appears, it allows drivers to turn in that direction, but only if it is safe and lawful to do so. The red light, however, fundamentally takes precedence, prompting drivers to ensure they stop and check for any potential hazards, including other vehicles, pedestrians, or cyclists, before proceeding. This ensures an orderly traffic flow and maintains safety on the roadways.

While one might think the green arrow permits an immediate turn, it does not override the instructions of the red light. Therefore, stopping at the red light is essential before any turn can be made, reinforcing the importance of obeying all traffic signals for safe driving practices.
