Texas DMV Written Driving Practice Exam

How far away should you signal before turning or changing lanes?

At least 50 feet At least 100 feet At least 150 feet At least 200 feet

Correct Answer:

At least 100 feet

Explanation:

Signaling at least 100 feet before turning or changing lanes is important for ensuring the safety of all road users. This distance provides sufficient time for other drivers and pedestrians to be aware of your intentions, allowing them to react accordingly. Proper signaling helps prevent collisions and promotes a smoother flow of traffic. While shorter distances like 50 feet may not give other road users enough warning, and longer distances like 150 or 200 feet could be unnecessarily excessive in many situations, the 100-foot mark serves as a good balance between visibility and practicality in urban and suburban driving environments. This standard helps maintain safe driving practices by fostering clear communication on the road.
