Practice 33 South Carolina DMV questions on signals. Answer interactively below with an instant explanation after every question.
Why: South Carolina law requires drivers to signal their intention to turn at least 100 feet before the maneuver. This rule applies to turning left or right, changing lanes, and merging into traffic.
Why: Extending your left arm downward is the standard hand signal to indicate you are slowing down or coming to a stop. This signal acts as a manual brake light to warn drivers behind you of your intention to reduce speed.
