Texas Car / Permit practice question · Safe Driving Practices
When driving at night, you should not 'overdrive' your headlights. This means you should:
Answer choices
- keep your speed low enough to stop within the distance your lights show— Correct answer
- always use high beams no matter the traffic
- follow the car ahead closely to use its lights
- turn your lights off on well-lit streets
Why this is the answer
Overdriving your headlights means going so fast that your stopping distance is longer than the distance your lights show. The glossary adds that low beams are good for stopping only up to 45 mph and high beams up to 65 mph. So keep your speed low enough to stop within the lit area ahead.
