Fact Sheet -Traction Law and Passenger Vehicle Chain Law
- Traction LawĀ (Code 15) - Use George's Head to Check Your Tread If weather conditions require, CDOT will implement a Traction Law.Under a Traction Law, motorists will need to have either snow tires, tires with theĀ mud/snow (M+S) designation, or a four-wheel/all-wheel drive vehicle - all tiresĀ must have a minimum 3-16th inch tread.
- Passenger Vehicle Chain LawĀ (Code 16) - Chain Up or Stay OffDuring severe winter storms, CDOT will implement a Passenger Vehicle Chain LawĀ - this is the final safety measure before the highway is closed. Under a Passenger Vehicle Chain Law, every vehicle on the roadway is required toĀ have chains or an alternative traction device (like AutoSock).
Fines
- Motorists driving with inadequate equipment during a Traction Law or PassengerĀ Vehicle Chain Law could be fined more than $130.
- If a motorist blocks the roadway because they have inadequate equipment during aĀ Traction Law or Passenger Vehicle Chain Law, they could be fined more than $650.
Test Your Tread
Find out if your tires are safe for winter driving by doing the Quarter Test:
- Insert a quarter upside down into your tire tread, with Washington's headĀ going in first.
- If the top of the head is covered by tread, you're good to go.
- If the top of his head is visible at any point around the tire (test multipleĀ points), you can't drive when a Traction Law is called - you also likely needĀ new tires.


Traffic Facts
- At 60 MPH on snowy pavement, winter tires require 310 ft. to stop. All-season tiresĀ require more than double that (668 ft.).
- In 2014, one of the worst traffic delays on the I-70 Mountain Corridor was caused byĀ unprepared motorists. Severe delays were caused by 22 vehicles spinning out andĀ causing crashes - 19 of those vehicles had worn tires.
- Traffic accidents - not volume - account for as much as 60 percent of all trafficĀ delays.
- A crash that only takes 10 minutes to clear can delay traffic for an hour.
