    Road Rules and Safe Driving Tips for Driving to Powder Mountain (HWY 158)

    Powder Mountain Road (HWY 158) is not one to be taken lightly. Make sure you’re prepared before making the trek up the hill.

    Did you know Powder Mountain Road (HWY 158) is one of the steepest roads in America? With a consistent grade of 14%, HWY 158 can be tricky to drive, especially during snowy winter conditions. In order to ensure your safety please abide by the new Utah Department of Transportation (UDOT) Snow Traction Policy below.

    All-wheel drive and 4-wheel drive vehicles must have:

    • M/S tires (Mud and Snow)
    • 3PMSF tires (All-Season)
    • Chains, snow socks, or other traction devices are also accepted.

    Vehicles with 2-wheel drive vehicles must have: 

    • Minimum of 3PMSF (All-Season Tires)
    • Must have chains, snow socks, or other traction devices

    UDOT or law enforcement agencies determine when road conditions require the use of these devices. Travelers are notified when they are required via road signs or message boards.

    During severe winter weather storms:

         •  Traction devices or 4-wheel/All-wheel drive cars are REQUIRED on HWY 158. Drivers will be subjected to a penalty if these requirements are not met!

    At Powder Mountain, we want everyone to get their share of the fluffy stuff, but in order to do so we ask you, our guests, to drive safe, be smart, and understand these requirements before you get to the best powder day of your life.
