What should you do when turning right at traffic lights showing a red arrow pointing right?

Answer: C — Stop until you receive a green arrow, then proceed safely

When encountering a red arrow pointing right at traffic lights, the appropriate action is to stop until you receive a green arrow and then proceed safely. A red arrow indicates that turning right is not permitted at that time, regardless of the traffic conditions. This regulation is intended to ensure safety at intersections, preventing conflicts with oncoming traffic or pedestrians who may have the right of way. The green arrow signifies that it is safe to turn, allowing you to proceed while also being aware of other vehicles and pedestrians. Adhering to this protocol helps maintain order on the road and reduces the risk of accidents. While it might seem intuitive to proceed immediately if the road is clear, doing so would violate the traffic signal and potentially create dangerous situations, particularly if a vehicle or pedestrian has the right to continue. The other options, such as stopping until the arrow disappears or turning if no other vehicles are present, do not align with the strict regulations that govern traffic signals, which are designed to protect all road users.
