When driving at night on an unlit road with no traffic nearby, high beams are helpful, but you must switch to low beams when:
- A.An oncoming vehicle is within 500 feet or you are within 300 feet behind another vehicle
- B.You enter any curve
- C.Another vehicle is a mile away
- D.You pass a road sign
Correct answer
A. An oncoming vehicle is within 500 feet or you are within 300 feet behind another vehicle
Why
The dimming distances are 500 feet for oncoming traffic and 300 feet when following. Following them prevents blinding other drivers.
