Request for New Partners for Cottonwood Canyons Sticker Program
September 27, 2023
Deadline to express interest is Wed., Oct. 4, 2023 at 9:00 a.m.

The UDOT Cottonwood Canyons sticker program is a winter safety, preparedness and education program specifically designed for the Cottonwood Canyons. The goal of this program is to increase vehicle safety and preparedness by pre-inspecting vehicle tires for winter driving conditions in advance of drivers traveling in the canyons. Our objectives with this goal are to help public transit function more efficiently and to help redirect underprepared drivers to transit, shuttles, carpooling or delaying travel until road conditions improve.
The sticker program is free of charge, completely voluntary, and will run from Nov. 1, 2023 to Feb. 28, 2024. Stickers are NOT REQUIRED to drive Big or Little Cottonwood Canyon. If a vehicle’s tires/traction devices meet the requirements, a sticker is placed on the windshield to show a vehicle has proper traction devices for traveling in the canyons when the Traction Law is in effect.
UDOT would like to increase the number of sticker inspection locations available to participants by partnering with additional tire shops. If your business is interested in participating in the sticker program, please see the requirements for partnership below.

- Meet with UDOT for a one-hour sticker program training and orientation between Oct. 5 – 20.
- Work within Google Forms & Spreadsheets for sticker program data collection and the inspection process.

Having a sticker does not guarantee access to the canyons, rather it verifies the vehicle’s tires meet the required equipment standards when the traction law is in effect.
- Vehicles may still be subject to inspection at the discretion of law enforcement.
- Having a sticker is not a requirement for vehicle travel in the canyons and does not allow holders to enter the canyon during closures.
- The sticker does not allow vehicles with the sticker to have priority to enter the canyons.
