New Jersey CDL General Knowledge: Mountain Driving Test 2026

New Jersey is not the Rockies, but the written exam still asks steep-grade questions, and this New Jersey CDL mountain driving test covers them. The Delaware Water Gap approaches and the long pulls on I-80 across the northwest corner are real enough to matter. Items focus on selecting a low gear before the descent rather than partway down it, the rule that you never coast in neutral, what an escape ramp is for, how brake fade develops when you ride the brakes, and the firm-application-then-release braking technique.

Weight, length of grade, road surface, and weather all change a safe descent speed, and the exam expects you to name those factors. The mountain driving section of the New Jersey CDL Manual is the source.

Format reminder for 2026: 50 questions on the New Jersey CDL general knowledge test, 80 percent required, so 40 correct answers. Repeat this mountain driving drill until gear-first thinking is automatic.
