South Carolina Driver's Permit Practice Exam

On a highway, how far before a turn should you signal?

1. 50 ft

2. 100 ft

3. 150 ft

4. 200 ft

The correct answer is: 100 ft

Signaling before making a turn is crucial for ensuring the safety of all road users. The correct answer, which suggests that you should signal at least 100 feet before a turn, aligns with best practices for driving safety. By giving this advance notice, you allow other drivers, cyclists, and pedestrians enough time to react to your intentions, which helps prevent accidents. This distance also gives you a buffer to safely maneuver into the next lane or prepare for the turn itself without abruptly changing your direction, which can surprise other road users. Adhering to this guideline fosters a smoother flow of traffic and enhances overall road safety. While other distances might seem appropriate, they do not provide as comprehensive a notice to surrounding drivers as the 100 feet does. For example, signaling too close to the turn can lead to confusion or unexpected maneuvers by other drivers, increasing the risk of collisions.
