Bicycle Highway-Access Laws in Utah
Last reviewed by BikeSize EditorialThis guide is for general information only and is not legal advice. Laws change - verify current rules with your state DOT or a licensed attorney before relying on this for any legal matter. Read full disclaimer.
The rule
Bicycles are permitted on Interstate highways in Utah. UDOT permits cycling on the shoulders of most Interstate segments in Utah (including substantial portions of I-15, I-70, I-80 and I-84) where no reasonable alternative parallel route exists. Specific urban segments along the Wasatch Front and several tunnels and bridges are signed prohibited; verify against UDOT bicycle-on-Interstate guidance before riding.
What this means in practice
Interstate cycling is legal in Utah, but ride only where you have a wide, clean shoulder and exit at the first signed bicycle exit when conditions deteriorate.
Bigger roads, longer rides
Size a road bike for shoulders, group rides, and rural highways
Highway-access and group-riding rules favour riders who can hold a straight line at speed. Start with a frame that fits.
