New York Tire Chain Laws
New York has no chain-up law for trucks. On a designated snow emergency route, when a snow emergency is declared, you need snow tires and/or chains (V.T.L. 145-c), so chains are one option, never strictly required. There is no R-1/R-2 pass system. The real tool is the Thruway Authority, which bans tandem and empty tractor-trailers on I-90, I-87, and I-84 during storms and can hold commercial trucks to the right lane. Check 511NY before you roll.

When, where, and what counts
- When required: No standing chain mandate. On a designated snow emergency route, when a snow emergency is declared, a vehicle needs snow tires and/or chains (V.T.L. 145-c), so chains are one option and never strictly required. During storms the Thruway Authority bans tandem and empty tractor-trailers and can hold commercial trucks to the right lane. There is no R-1/R-2 pass system.
- Where: Snow emergency routes are set by the state or a municipality. The Thruway and DOT bans hit I-90, I-87, I-287, I-84, I-190, and downstate corridors. No mountain-pass chain-up system exists. For voluntary traction, the Southern Tier and Adirondack grades are the worst.
- Applies to: The snow-emergency-route rule applies to all vehicles on a designated route during a declared emergency. Thruway and DOT storm bans target tandem and empty tractor-trailers and can restrict all commercial vehicles to the right lane.
- Chains vs traction devices: Chains satisfy the snow-emergency-route rule, but so do snow tires, so chains are never strictly required. Link and cable chains are legal. Studded tires are legal October 16 through April 30. AutoSock and textile devices are not addressed.
- Check the live order: 511NY at 511ny.org, plus NYSDOT and the New York State Thruway Authority alerts, for the current snow-emergency and truck-ban status.
- Fine: None specific to chains. Snow-emergency-route and equipment violations are traffic infractions. Violating a Thruway tandem or empty-trailer ban carries the Thruway Authority penalties set by the order.
