UDOT TRACTION LAW //
What is the “Traction Law” and what are “Traction Devices”?
It is important to ensure that you have traction devices appropriate for winter driving conditions, snow-worthy tires or chains are not just for your safety, it is the rule of the road. Traction devices are required during severe winter weather conditions on roadways throughout Utah, including Big and Little Cottonwood Canyons.
AWD/4WD: M + S or M/S tires is the minimum requirement. Traction devices such as chains or 3 peak mountain snowflake (3PMSF) tires are also acceptable.
2WD: 3 peak mountain snow flake (3PMSF) tires (on all four tires) is the minimum requirement. Traction devices such as chains are also acceptable.
TRACTION LAW FREQUENTLY ASKED QUESTIONS
- UDOT is working on adding a class 3 segment to the rule which would require traction devices to be in the vehicle (chains) or on (M+S / 3PMSF rated, snow tires) at all times. Big and Little Cottonwood Canyons (S.R. 190, S.R. 210) would be included under the class 3 segment.
- The Traction Law would be in effect from October 15 to March 31, regardless of conditions.
- UDOT will observe if these changes make a difference in reducing slide offs/crashes as a result of unprepared vehicles to determine if the new rule should remain in place.
