Which lighting choice is specifically permitted when using fog lamps?
Correct answer: A – Low-beam headlights with the fog lamps
Nevada law permits lighted fog lamps to be used with lower headlamp beams. The driver’s handbook also advises using headlights when driving in fog because visibility is reduced. Parking lights or hazard flashers are not substitutes for the required headlamps while driving under low-visibility conditions.
