Rules of the Road
You should NOT use high beams:
Show Answer & Explanation
Correct Answer: B. When following another vehicle closely, approaching oncoming traffic within 150 m, or in fog/heavy rain/snow
High beams reflect off fog droplets, rain, and snow, reducing visibility. They also blind drivers in front (via rear-view mirror) and oncoming (direct). The 150-metre rule prevents the latter.
Why the other answers are wrong
- A.On a dark rural highway with no other vehiclesIsolated rural highway is when high beams should be used.
- C.In a lit urban areaUrban areas often have sufficient street lighting; high beams are still discouraged but not forbidden unless oncoming.
- D.On a freeway at nightFreeway at night with distant oncoming is an appropriate time for high beams.
