Texas Driver's License Knowledge TestSafe Driving PracticesEasy
When driving at night, a driver observes an oncoming vehicle approaching. The driver should dim their high beams when the oncoming vehicle is within approximately what distance?
- A1000 feet
- B100 feet
- C200 feet
- D500 feet
Show answer & explanationAnswer & explanation
Correct answer: D. 500 feet
Texas law requires drivers to dim their high beams when an oncoming vehicle is within 500 feet to prevent blinding the other driver. This is a critical safety practice for night driving.
Why the other options are wrong
- A. 1000 feet is further than required by law, though safer, it's not the minimum legal requirement.
- B. 100 feet is too close; the other driver would already be blinded.
- C. 200 feet is also too close and does not comply with Texas law.
High Beam Dimming Rule
Drivers must dim their high beams when an oncoming vehicle is within 500 feet, or when following another vehicle within 300 feet.
- Prevents glare and temporary blindness for other drivers.
- Applies to both oncoming and preceding vehicles.
- Legal requirement in Texas.
Memory trick: Five hundred for oncoming, three hundred for following, always be dimming.
