A driver is traveling at night on an unlit road and encounters an oncoming vehicle. When must the driver dim their high-beam headlights?
- AWithin 500 feet of the oncoming vehicle.
- BWithin 200 feet of the oncoming vehicle.
- CWithin 100 feet of the oncoming vehicle.
- DWithin 1000 feet of the oncoming vehicle.
Show answer & explanationAnswer & explanation
Correct answer: A. Within 500 feet of the oncoming vehicle.
Texas law requires drivers to dim their high-beam headlights when an oncoming vehicle is within 500 feet. This prevents blinding the other driver and ensures their safety.
Why the other options are wrong
- B. 200 feet is also too close and does not meet legal requirements.
- C. 100 feet is too close; the oncoming driver would be blinded.
- D. While safer, 1000 feet is not the minimum legal requirement.
High Beam Dimming Rule
Drivers must dim their high-beam headlights when an oncoming vehicle is within 500 feet, or when following another vehicle within 300 feet, to prevent blinding other drivers.
- 500 feet for oncoming traffic.
- 300 feet when following.
- Prevents blinding other drivers.
Memory trick: Five hundred feet, you dim the light, for oncoming sight.
