New Jersey Truck Speed Limit
No mandatory split in New Jersey — trucks run the posted 65 on interstates, 55 on the urban stretches (N.J.S.A. 39:4-98.5). But the state can sign a 5 mph lower limit for trucks 10,000 lb and over on four-lane state highways, so watch the truck-speed signs (39:4-98.1). Fines double automatically anywhere the limit is 65 (39:4-98.6), and again in work zones and Safe Corridors (39:4-203.5) — no posted sign required.
How fast a truck can run in New Jersey
No mandatory split in New Jersey — trucks run the posted 65 on interstates, 55 on the urban stretches (N.J.S.A. 39:4-98.5). But the state can sign a 5 mph lower limit for trucks 10,000 lb and over on four-lane state highways, so watch the truck-speed signs (39:4-98.1).

Truck-specific rules and quirks
- On the Turnpike's dual-dual sections cars and trucks are separated into inner and outer lanes, but the limit is the same 65.
- No standing statewide truck split, but 39:4-98.1 lets the state post a 5 mph lower limit for trucks 10,000 lb and over on four-lane state highways signed 50 mph or higher — watch for the truck-speed signs.
What a speeding ticket costs
Fines double automatically anywhere the limit is 65 mph (39:4-98.6), and again in work zones and designated Safe Corridors (39:4-203.5) — the state doesn't even need the sign posted to charge you. Speeding 20+ over adds surcharges.
