What is the “Traction Law” and what are “Traction Devices”?

The Traction Law is Utah’s administrative rule (R20-6) that the Utah Department of Transportation (UDOT) and law enforcement implements during severe winter driving conditions. 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 snowflake (3PMSF) tires (on all four tires) is the minimum requirement. Traction devices such as chains are also acceptable.
