Driving Requirements

đźš— Stay safe to ski more.

It's the law.

Snowbird along with the Utah Department of Transportation (UDOT) and Unified Police have the utmost concern for the safety of visitors and guests coming up to the mountains. Making sure your vehicle is properly equipped for the conditions should be the first step in having a great day on the slopes.

The Traction Law

If it’s snowing on State Route 210—the road through Little Cottonwood Canyon to Snowbird—UDOT’s Traction Law will almost certainly be in effect. This law requires that all vehicles traveling S.R. 210 be equipped with traction devices. Drivers are notified when the Traction Law is in effect via UDOT road signs, message boards and social media feeds.


Winter Checklist

  • At a minimum, 4-Wheel Drive or All-Wheel Drive vehicles must have approved snow tires on all 4 tires on the vehicle.
  • Approved tires can be identified by an M+S (mud and snow) or a Snowflake symbol on the sidewall of the tire.
  • Tires must have sufficient tread to be effective.
  • 2-Wheel drive vehicles must have 3PMSF tires or tire chains properly fitted on all 4 tires of their vehicle before entering the canyon.
  • Properly sized tire chains must be in your possession if snow tires are not mounted to your vehicle.


Police Officers at the entrance of Little Cottonwood Canyon will make the determination of a vehicle's safety based on known road condition information. 2-wheel drive vehicles with 4 mounted snow tires MAY be denied access to the canyon if law enforcement believes they present a hazard to other motorists. Locals can expedite Traction Law screening by participating in UDOT’s Cottonwood Canyons Sticker Program

Rental Cars 

Traction devices are not standard issue on cars rented within Utah. If you’re visiting Snowbird from out of state and renting a vehicle during your stay, verify with the rental company that your reserved vehicle is AWD or 4WD and has M+S or 3PMSF rated tires on all wheels.
