New Jersey CDL General Knowledge: Communicating Test 2026

Communication in a commercial vehicle happens through lights, horn, and road position, and this New Jersey CDL communicating and signaling test checks whether you use all three the way the manual expects. Expect items on signaling early for turns and lane changes, holding the signal through the maneuver, warning traffic behind you when you slow or stop on the shoulder, running flashers on a slow climb, tapping the horn only when it genuinely prevents a crash, and making eye contact with drivers who may not have seen your rig.

New Jersey traffic is dense and impatient, so predictable signaling is the cheapest safety tool you own. The communicating chapter of the New Jersey CDL Manual also spells out the reflective triangle placement distances this drill tests.

Keep the format in mind: the New Jersey CDL general knowledge exam runs 50 questions, and 40 of them - 80 percent - must be right. Signaling items are free points in 2026 once the distances stick.
