When can you legally turn right on red?

Turning right on red is legally permitted under certain conditions. The correct response highlights that you must first come to a complete stop before making the turn. This ensures that you observe your surroundings carefully, allowing you to yield to any pedestrians crossing the street as well as oncoming traffic that may still be proceeding through the intersection.

In many jurisdictions, the law mandates that drivers must yield to any traffic or pedestrians present before completing the turn, prioritizing safety. This process helps prevent accidents and ensures that drivers fully assess the situation for any potential hazards.

The other context options fail to acknowledge the importance of safety and legal requirements accompanying the turn. For instance, turning when no cars are behind you does not justify the action if you haven't checked for pedestrians or oncoming traffic. Signs indicating where turns are permitted are also vital, but you must ensure safety by stopping first. While designated intersections do play a role, the primary rule is more about the act of stopping and yielding rather than the location alone.
