Do I need chains in Washington, DC?

DC has no chain mandate. From October 15 to April 15, a driver may not stall on a Snow Emergency Route because the driving wheels lack tire chains or effective snow tires. Check the official sources linked on this page for the published requirements and penalties. Follow the posted sign and the official source. Some requirements apply even when no sign is up.
