Signs, Flags, and Lights Requirements

For the safety of other drivers on the roadways, signs, flags, and lights may be required.

Signs

Posted signs must be 7 feet by 18 inches, set on a yellow background with 10-inch high black letters in accordance with the Federal Highway Administration Standard Alphabet Series C. Letters must be painted with a 1-5/8 inch stroke, displaying “OVERSIZE LOAD.”

Signs in the front can be fixed to the front bumper or on the top of the vehicle’s cab. Rear signs must be set on the rearmost part of the vehicle or load, and if this is not possible, they should be as far back on the rear of the vehicle cab as possible. The load cannot obstruct the sign. The bottom edge of the sign should be positioned no more than 5  feet above the road, if possible.

Flags

Red or orange flags must be affixed on extremities when:

• A vehicle or load exceeds ten feet in width
• Loads on a vehicle exceeding three feet to the front or four feet to the rear of the bed or body while in operation
• Flags must be completely clean and not torn, faded, or worn out and must be fastened to wave freely

Over-dimensional flagging is not required on LCVs.

Lights

Oversize non-divisible load lighting requirements are as follows:

• Warning lights required when headlights are necessary;
• Front overhang of more than three feet must be marked with a steady, amber marker light and red flag;
• Rear overhang exceeding four feet must be marked with red clearance lights for night travel;
• Vehicles with front or rear overhang exceeding 20 feet from the front or rear bumper of a vehicle, or from the center of the closest axle in the absence of a bumper, a rotating or flashing beacon visible from a minimum of 500 feet, and must be displayed at a minimum height of four feet above ground;
• Tow vehicle headlights must be operated on low beam, day or night, as an additional warning to traffic; 
• Nighttime travel, when authorized by the division may be permitted with marker lights indicating extreme width using amber lights front and center, and red lights to the rear.

Loads exceeding 92 feet overall length are required to have proper lighting every 25 feet, with amber lights to the front and sides of the load marking extreme width, and red to the rear.

Obtaining a Permit

The appropriate permit  — in either paper or electronic format — for oversize vehicles and loads must be obtained prior to operating within the State of Utah, except when entering on I-15 (St. George Port of Entry) and West bound I-80 (Echo Port of Entry) and East bound I 80 at (Wendover Port of Entry).

Permits are issued on a single-trip, semi-annual, or annual basis.. Because of additional processing requirements, loads exceeding 17′ 6″ H, 17′ W, or over 300,000 lbs. will only be processed during Monday through Friday from 8 a.m. to 5 p.m. Mountain Standard Time, and may take up to 14 days for approval.

Permits can be obtained online with a major credit card at the Utah Department of Transportation website at https://www.udot.utah.gov/connect/business/permits/commercial-trucking-permits/.
