Utah’s winter landscapes are breathtaking, but they come with their fair share of driving hazards. Snow-covered roads, icy passes, and unpredictable storms make proper tire and chain usage essential for safe travel. Whether you’re a local navigating daily commutes or a visitor heading to the ski slopes, understanding Utah’s snow tire and chain requirements can help keep you safe during winter driving and avoid costly fines.
In this blog, we’ll cover everything you need to know, including Utah’s laws on snow tires and chains, when and where they’re required, and how to prepare your vehicle for winter roads.
Understanding Utah’s Snow Tire and Chain Laws
Utah’s Department of Transportation (UDOT) enforces specific snow tire and chain requirements in designated areas when winter conditions make roads hazardous. These rules aim to prevent accidents and keep roads clear for all travelers.
When Are Snow Tires or Chains Required?
UDOT issues Traction Laws when necessary, meaning that certain vehicles must have appropriate traction devices to continue driving safely. These laws are most commonly enforced on steep, high-altitude roads like Big Cottonwood Canyon (SR-190) and Little Cottonwood Canyon (SR-210), leading to popular ski resorts like Snowbird, Alta, Brighton, and Solitude.
- From October 1st to April 30th, UDOT may require vehicles to have snow tires, chains, or AWD/4WD capabilities.
- During active storms or when road conditions worsen, UDOT enforces a Traction Law, meaning drivers without the required equipment can be fined or denied road access.
Types of Vehicles and Their Winter Requirements
Utah’s traction laws classify vehicles into different categories, each with specific requirements:
1. Passenger Vehicles (Sedans, SUVs, Small Trucks)
Drivers must comply with one of the following when a traction law is in effect:
- Snow tires with at least 3PMSF (Three-Peak Mountain Snowflake) certification
- Mud and snow (M+S) tires with at least 3/16-inch tread depth
- Tire chains or traction devices
- All-wheel drive (AWD) or four-wheel drive (4WD)
Vehicles that do not meet these requirements can be ticketed or turned around.
2. Commercial Vehicles (Semi-Trucks, Large Vans, Buses)
Commercial vehicles must carry chains between October and April if traveling on designated routes. When UDOT enforces a chain law, truck drivers must install chains on at least two drive wheels. Failure to do so can result in hefty fines and potential delays.
What’s the Difference Between Snow Tires and Chains?
Understanding the difference between snow tires and chains can help you choose the right option for your vehicle.
Snow Tires
- Designed with a softer rubber compound for improved grip in cold temperatures.
- Feature deeper treads and special patterns to channel snow and slush away.
- Best for drivers who frequently travel in snowy or icy conditions.
Tire Chains
- Metal chains wrapped around tires for maximum traction on ice and deep snow.
- Typically required in extreme winter conditions or on steep, mountainous roads.
- Must be installed before reaching hazardous road sections.
If you’re unsure whether to invest in snow tires or chains, consider how often you drive in winter conditions. For everyday winter driving, snow tires are ideal. If you only encounter snow a few times per year, carrying chains for emergency use may be the best option.
Where Are Snow Tires or Chains Required in Utah?
Utah has specific highways and canyons where snow tires or chains may be required. Some of the most common areas include:
1. Big Cottonwood Canyon (SR-190) and Little Cottonwood Canyon (SR-210)
- Home to popular ski resorts like Brighton, Solitude, Snowbird, and Alta.
- Snow tire and chain restrictions are frequently enforced from October through April.
- AWD or 4WD vehicles are strongly recommended.
2. Parley’s Canyon (I-80)
- A major route connecting Salt Lake City to Park City and Summit County.
- Known for heavy snowfall and frequent ice buildup.
- When the traction law is in effect, passenger vehicles without proper traction devices may be denied access.
3. Sardine Canyon (US-89)
- A common route between Brigham City and Logan.
- Snowfall and ice can make driving conditions treacherous.
4. Logan Canyon (US-89)
- A scenic but dangerous winter road leading to Bear Lake.
- Chain and snow tire requirements are enforced when conditions worsen.
How to Properly Install Tire Chains
If your vehicle requires chains, follow these steps to install them properly:
- Practice Before You Need Them – Don’t wait until you’re stuck in the snow.
- Park on a Flat, Safe Area – Engage your parking brake.
- Lay Chains Flat – Untangle them and ensure they are facing the correct direction.
- Drape Chains Over Tires – Ensure even distribution.
- Drive Forward Slightly – This helps secure the chains in place before tightening.
- Re-Tighten After a Few Miles – Stop and check your chains to ensure a snug fit.
Improper installation can lead to damage to your vehicle or a loss of control while driving.
Penalties for Ignoring Snow Tire and Chain Laws in Utah
Failure to comply with UDOT’s traction laws can result in:
- Fines starting at $100 if you’re caught without proper traction devices.
- Increased fines up to $1,000 if your vehicle blocks traffic or causes an accident due to non-compliance.
Enforcement is particularly strict in ski areas, where winter accidents can cause major disruptions.
Tips for Safe Winter Driving in Utah
Even if your car meets traction requirements, winter driving can still be challenging. Here are some additional winter safety tips:
- Drive Slowly – Reduce your speed, especially on turns and downhill slopes.
- Increase Following Distance – Maintain at least 5-6 seconds between you and the car in front.
- Avoid Sudden Movements – Accelerate, brake, and turn gradually to prevent skidding.
- Use Low Gears on Hills – Helps maintain traction on steep, icy roads.
- Keep an Emergency Kit – Include a flashlight, blankets, jumper cables, food, and water in case of breakdowns.
If conditions become too dangerous, the best option is to stay off the road and wait until conditions improve.
