Arkansas Commercial Driver License (CDL) Practice Test

How should you signal turns or lane changes?

1. Signal early

2. Signal continuously

3. Cancel signal after the maneuver

4. All of the above

The correct answer is: Signal early

The correct response encompasses the need to signal early. Signaling early allows other drivers and road users to anticipate your intentions, which is crucial for safety, especially in commercial driving where the vehicle's size and weight can create a longer stopping distance and make sudden movements more difficult. While continuous signaling and canceling the signal after the maneuver are also important practices, signaling early is the primary action that enhances communication on the road. It emphasizes proactive driving, letting others know you will be making a turn or a lane change well in advance, allowing them to adjust their speed or position accordingly. Each of these actions contributes to overall road safety, but signaling early lays the groundwork for effective communication among drivers.
