- CWhen within 200 feet of an oncoming vehicle.
- DWhen within 300 feet of an oncoming vehicle.
Show answer & explanationAnswer & explanation
Correct answer: B. When within 500 feet of an 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
- A. Waiting for the other driver to flash their lights is reactive and means you've likely already blinded them, which is unsafe and illegal.
- C. 200 feet is too close; the other driver would already be blinded.
- D. 300 feet is also too close and does not meet the legal requirement.
Headlight Dimming Distance
Texas law specifies the distance at which drivers must dim their high-beam headlights for oncoming traffic to prevent glare.
- Dim high beams for oncoming vehicles.
- Required when within 500 feet.
- Prevents blinding other drivers.
Memory trick: Five hundred feet, then dim your light, keep everyone safe at night!
