New Jersey Tire Chain Laws

How New Jersey handles chains

New Jersey has no chain-up law for trucks. Chains are legal only while the road is slippery, and you take them off once the pavement clears (39:3-73). No DOT sign turns a chain requirement on anywhere in the state. In a severe storm, NJDOT can bar trucks from named highways by order. In February 2026 it barred tractor-trailers and empty straight trucks from I-78, I-80, I-287 and six other highways. Before you drive, clear snow and ice from the cab and trailer top (39:4-77.1). Check 511nj.org and NJDOT before a storm run.

When, where, and what counts

• When required: Never mandated. Chains are optional and legal only while the road is slippery from rain, snow, ice, oil, or any other cause. No sign, board, or DOT order activates a chain requirement in New Jersey.
• Where: No mandate anywhere in the state. Voluntary traction is most useful on I-80 and I-287 through the northwest highlands and on I-78 west of the ridge.
• Applies to: All vehicles may run chains for safety; none are required. No CMV or weight threshold applies.
• Chains vs traction devices: Chains must be of reasonable proportions and mounted so they cannot be thrown and endanger anyone (39:3-73). The statute addresses only tire chains and does not mention cable chains or textile devices like AutoSock. Nothing is required.
• Check the live order: 511nj.org or NJDOT for road and weather conditions and storm-time commercial vehicle travel restrictions. There is no chain-control status to check because none exists.
• Fine: None for chains. Chains are optional, so there is no chain-up penalty. Running chains on bare pavement when conditions do not warrant it is a minor equipment violation.
