Texas Driver's License Knowledge TestSafe Driving PracticesHard
A driver is following another vehicle at night on an unlit rural road. How far ahead should the driver's high-beam headlights illuminate the road effectively?
- AApproximately 350 feet.
- BApproximately 200 feet.
- CApproximately 100 feet.
- DApproximately 450 feet.
Show answer & explanationAnswer & explanation
Correct answer: D. Approximately 450 feet.
High-beam headlights should illuminate the road for approximately 450 feet, allowing the driver to see objects and react safely at higher speeds common on rural roads. Low beams illuminate about 250 feet.
Why the other options are wrong
- A. 350 feet is still less than the optimal illumination provided by high beams.
- B. 200 feet is too short for high beams and inadequate for safe speeds on unlit rural roads.
- C. 100 feet is significantly less than what high beams provide; this might be closer to parking light visibility.
High Beam Effectiveness
The approximate distance high-beam headlights can illuminate the road ahead, providing critical visibility for night driving, especially on unlit roads.
- Illuminates further than low beams (approx. 450 ft).
- Used on unlit roads when no oncoming traffic or vehicles ahead.
- Must be dimmed when approaching or following other vehicles.
Memory trick: High beams reach far, like a shooting star, 450 feet, that's the bar!
