Texas Drivers Ed Written Practice Test

At night, a driver should dim his headlights when an oncoming car comes within:

1. 1000 feet

2. 500 feet

3. 250 feet

4. 100 feet

The correct answer is: 500 feet

The correct answer is 500 feet, as this distance is established to ensure that drivers do not blind each other with their high beams during night driving. Dimming headlights when an oncoming vehicle is within this range helps to maintain visibility for both drivers while also adhering to safety laws regarding headlight use. While options indicating shorter distances may seem plausible, they do not align with legal requirements or optimal safety practices. For instance, dimming headlights too soon could lead to insufficient visibility for the driver, while waiting too long to dim them could risk blinding the approaching driver. Thus, 500 feet strikes a balance between safety for both parties on the road.
