New Jersey CDL General Knowledge: Night Test 2026

Bad conditions get their own cluster on the exam, and this New Jersey CDL night, fog, winter, and hot weather driving test gathers all of it into one drill. Night items cover overdriving your headlights, glare recovery, and keeping glass and lamps clean. Fog items push the answer nobody likes: often the safest move is getting off the road and waiting it out. Winter questions run through coolant and antifreeze, exhaust and defroster function, tire chains, black ice on bridges, and the wet shine on mirror arms that really means ice.

Hot weather items cover tire pressure, engine overheating, bleeding the air tanks, and soft tar on the pavement. Nor'easters and coastal fog both hit New Jersey routes, so this is practical study.

Passing the New Jersey CDL general knowledge exam takes 40 of 50 questions correct, an 80 percent standard. Use the extreme conditions chapter of the New Jersey CDL Manual with this 2026 practice test.
