New Jersey Tire Chain Laws

New Jersey has no chain-up law for trucks. Chains are legal only while snow or ice makes the road 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. Your one duty is to drive for the conditions and stop when traction fails. Carry chains for the mountains you cross next, not for New Jersey.
