Utah Axle Regulations

Maximum Legal Weight Allowed

The maximum gross and axle weight limitations are as follows and may not be operated in excess of:

Wheel, Axle, Gross                              Weight Limitation

Single Wheel                                         10,500 pounds

Single Axle                                             20,000 pounds

Tandem Axle                                         34,000 pounds

Tridem Axle                                           Must comply with bridge formula

Gross Vehicle Weight                          80,000 pounds

An overweight permit must be obtained to authorize any exception to the maximum weight limitations listed above.

Use the Federal Bridge Formula to determine the weight on groups of axles to reduce the risk of damage to highway bridges. Allowable weight depends on the number of axles a vehicle has and the distance between those axles. However, the single-or-tandem-axle weight limits supersede the Bridge Formula limits for all axles not more than 96 inches apart.

Maximum Permit Weight Allowed

Utah Road Conditions

Work Zone Traffic Laws - In Utah, the enhanced penalty is applicable only when workers are present and/or if signs are posted.

• Expect the unexpected -- • Slow down -- Speeding is one of the major causes of work zone crashes.

• Don’t tailgate -- The most common crash in a highway work zone is the rear end collision.

• Keep your distance -- Keep a safe distance between your vehicle and the construction workers and their equipment.

• Pay attention to the signs -- Observe the posted signs until you see the one that says you’ve left the work zone.

• Obey road crew flaggers -- A flagger has the same authority as a regulatory sign, so you can be cited for disobeying his or her directions.
