All the best on your upcoming test! You can turn right on red in Ohio, as long as there is no traffic control device in place at the light that prohibits the turn.
Turning right on red has been legal in Ohio since 1975, but there are some parameters to this leeway. First, you must make sure that there isn’t a No Turn On Red **sign posted at the traffic light. If there is, you must wait for the light to turn green before you turn. If there is no traffic control device at the red light, you must take proper care to **stop and assess your surroundings before you proceed.
