safe-driving
At a red signal, what must happen before a South Carolina driver turns right where no sign forbids the turn?
- Stop first, check that no sign prohibits the turn, and yield before turning
- Only after the signal changes to green
- Whenever the driver sounds the horn first
- Only when another vehicle is turning left
Answer: Stop first, check that no sign prohibits the turn, and yield before turning. A right turn on red is permitted after the driver stops, unless a sign prohibits the turn, and the driver must yield to pedestrians and other traffic lawfully using the intersection. Waiting for green is unnecessarily restrictive, while a horn or an opposing left turn does not create permission. The stop must occur before the near-side crosswalk, stop line, or intersection as applicable. The quick cue is stop, check the prohibition sign, then yield before turning, rather than treating red as an automatic green for right turns.
