CDL · Night and weather
At night, within what distance of an oncoming vehicle, and within what distance of a vehicle you are following, should you dim your high beams?
Correct answer: 500 feet; 500 feet.
Answer options
- A200 feet; 100 feet
- B300 feet; 200 feet
- C500 feet; 500 feet Correct
Why
Bright high beams can dazzle the drivers around you, so dim them within 500 feet of an approaching vehicle and when following another vehicle within 500 feet. In fog, rain or snow, low beams also work better because high beams bounce back off the moisture.
