Chapter 16
General Oversize Permit Provisions
OBTAINING OVERSIZE PERMITS
Before moving a vehicle or load, which exceeds legal dimensions as outlined in the Legal Vehicle Dimensions a permit must be obtained and carried in the vehicle for inspection by law enforcement personnel. Destroyed or illegible permits may be re-printed or replaced at any port of entry.
The appropriate permit for oversize vehicles and loads, including special mobile equipment, must be obtained prior to operating within the State of Utah, except when entering on I-15 (St. George), I-80 (Echo and Wendover), and I-70 (Loma, Colorado).
Note: These ports are located at the border and permits are available upon entry. If port of entry is closed permits may be purchased online, or contact the closest port of entry or the Motor Carrier Division. Contact information can be found in the Utah Agency Directory Section.
Permits may be purchased online at www.udot.utah.gov/public/mcs prior to entry. Permits may be purchased by major credit card and may be issued based on annual permit dimensions and weight, or on a single trip basis.
The following conditions must be met to obtain a permit:
- Be in compliance with all financial responsibility obligations as specified under 49 CFR 387, R909-1.
- Vehicle(s) must be properly registered. UCA 41-1a-101
- Driver(s) are properly licensed with appropriate endorsements.
- Must be in compliance with the Federal Motor Carrier Safety Regulations (FMCSRs). 49 CFR Parts 382-399
- Must be in compliance with the Hazardous Material Regulations (HMRs).49 CFR Parts 171-180
- Must be in compliance with all UCR requirements
LIABILITY OF PERMITTEE
The applicant or permittee, as a condition for obtaining an oversize permit, shall assume all responsibility for crashes, including injury to any persons or damage to public or private property caused by operations.
INDEMNITY CLAUSE
The applicant or permittee agrees to indemnify and hold harmless the Department from any and all claims resulting directly or indirectly from the operation and/or transportation of vehicles or combination of vehicles operating under an oversize/overweight permit.
PERMIT REVOCATION, SUSPENSION AND CONFISCATION
Vehicles operating under an oversize/overweight permit shall not be operated in excess of the posted speed limit or the speed indicated on the permit, whichever is less. In no case shall a permitted movement proceed at a speed which shall endanger the safety of persons or property. Permits shall be subject to confiscation for speed violations.
Violation of the terms or conditions of an oversize/overweight permit, including but not limited to: speeding, lane travel, weather, load securement, Federal Motor Carrier Safety Regulations, and/or Hazardous Material Regulations may result in the revocation, suspension, or confiscation of the permit. Before the vehicle can be moved, it must be made legal, properly permitted, and violations corrected.
Patterns of non-compliance at a company level may constitute action taken against the carrier's overall permit privileges and may result in additional civil penalties and an order to cease operations.
WEATHER TRAVEL RESTRICTIONS
49 CFR 392.14
Extreme caution in the operation of a commercial motor vehicle shall be exercised when hazardous conditions are present, such as those caused by snow, ice, sleet, fog, mist, rain, dust, or smoke, adversely affect visibility or traction. Speed shall be reduced when such conditions exist. If conditions become sufficiently dangerous, the operation of the commercial motor vehicle shall be discontinued and shall not be resumed until the commercial motor vehicle can be safely operated. Whenever compliance with the foregoing provisions of this rule increases hazard to passengers, the commercial motor vehicle may be operated to the nearest point at which the safety of passengers is assured.
No carrier shall operate an LCV combination, with a combined trailer length in excess of 81 feet, when the following conditions exist:
- Wind in excess of 45 mph
- Snow and ice on the roadway
- Visibility less than 1,000 feet
When any of the above conditions exist the carrier may choose one of the following options:
- Cease operations until weather conditions improve
