Follow-up vehicles or escorts are also required for permitted vehicles and loads unable to maintain a minimum speed of 45 miles per hour on any highway, whether four-lane or two-lane.
The UDOT may apply escort vehicle requirements at its discretion when sight distance is deficient or when the width and character of the route are such that an escort vehicle(s) is necessary to provide advance warning to the motoring public.
Flagpersons
During the movement of an overdimensional load or vehicle, the pilot escort driver in the performance of flagging duties, may control and direct traffic to stop, slow, or proceed in any situations where it is deemed necessary to protect the motoring public from the hazards associated with the movement of the overdimensional load or vehicle. The pilot escort driver, acting as a flagger, may aid the load or vehicle in the safe movement along the highway designated on the permit and must:
- Assume the proper flagger position outside the pilot escort vehicle, and as a minimum, have in use the necessary safety equipment in section 6E.1 of the Manual on Uniform Traffic Control Devices (MUTCD);
- Use STOP and SLOW paddles or 24-inch red or fluorescent orange or red square flags to indicate emergency situations and other equipment as described in section 6E.1 of the MUTCD; and
- Comply with the flagging procedures and requirements as set forth in the MUTCD and the Utah Department of Transportation Flagger Training Handbook.
Escort car/company requirements
Escort vehicles must meet the following requirements:

Pilot escort vehicles must be equipped with a two-way radio capable of transmitting and receiving voice message over a minimum distance of one-half mile. Radio communications must be compatible with accompanying pilot escort vehicles, utility company vehicles, permitted vehicle operators, and police escorts, when necessary. When operating with police escorts, a CB radio is required.
Pilot escort must be equipped with the following safety items:
- Standard 18-inch or 24-inch red/white STOP & black/orange SLOW paddle signs (for nighttime travel moves, signs must be reflective according to MUTCD standards);
- Eight red-burning flares, glow sticks, or an approved alternate;
- Nine reflective triangles or 18-inch reflective orange traffic cones (not to replace the flares or cones required in this equipment list);

- Six-inch minimum length red or orange cone or traffic wand for use when directing traffic;
- Orange hard hat and Class 2 safety vest (Class 3 safety vests are required for nighttime travel moves);
- Height measuring pole, of a non-conductive non-destructive, flexible material (only required when escorting any load exceeding 16 feet in height);
- Fire extinguisher;
- First aid kit, clearly marked as such;
- One spare OVERSIZE LOAD sign, seven feet by 18 inches;
- Serviceable spare tire, tire jack, and lug wrench; and
- Handheld two-way simplex radio or other compatible form of communication for operations outside pilot escort vehicles.
Vehicles should not have unauthorized equipment on the vehicle, such as those generally reserved for law enforcement personnel.
Pilot escort vehicle drivers must possess current certificates of insurance or endorsement that indicates the operator, or the operator's employer, has in full force and effect no less than $750,000 combined single limit coverage for bodily injury and property damage as a result of the operation of the escort vehicle, the escort vehicle operator, or both, causing bodily injury and property damage arising out of an act or omission by the pilot escort vehicle operator of the duties required by the regulations. Such insurance or endorsement must be maintained at all times during the term of the pilot escort certification. Pilot escort vehicles shall have a minimum amount of $750,000 liability (this is not a cumulative amount).
Pre-trip planning and coordination meetings must be held prior to a load movement. Certified pilot escort operators must refer to highway restrictions specified in the secondary highway restrictions prior to all load movements.
Escort certification
Every person who drives a pilot/escort vehicle to escort over-dimensional/permitted loads in the state of Utah must meet the following requirements:
- Be a minimum of 18 years of age;
- Possess a valid driver’s license for the state or jurisdiction in which he/she is a resident;
- Obtain and carry in their possession at all times while in pilot/escort operations, a certification card issued by an authorized Qualified Certification Program; and
- Meet the requirements of 49 CFR 391.11 if using a vehicle for escort operations in excess of 10,000 pounds.
Within 30 days, pilot escort drivers must provide a current motor vehicle record (MVR) certification to the qualified certification program at the time of the course.
Pilot/escort vehicle operators must never allow passengers under 16 years of age in pilot escort vehicles during the movement of oversize loads or perform work as a tillerman while performing pilot escort operations.
The pilot escort vehicle certification process includes the following:
- Drivers domiciled in Utah must complete a Utah pilot escort certification course authorized by the Division (a list of authorized instructors may be obtained by calling (801) 965-4892);
- Pilot escort drivers domiciled outside of Utah may operate as a certified pilot escort driver with another state's certification credential, provided the course meets the minimum requirements outlined in the Pilot Escort Training Manual - Best Practices Guidelines as endorsed by the Specialized Carriers and Rigging Association, Federal Highway Administration, and the Commercial Vehicle Safety Alliance;
- The department may enter into a reciprocal agreement with other states provided that the course materials are comprehensive and meet minimum requirements;
- The pilot escort driver's initial certification expires four years from the date issued and it is the responsibility of the driver to maintain the certification; and
- One additional four-year certification may be obtained through a mail-in or online re-certification process provided by a qualified pilot escort training entity.
Escort car signs, flags, and lights
Pilot escort vehicles must display an OVERSIZE LOAD sign mounted on the top of the pilot/escort vehicle. The sign must be a minimum of five feet wide by 10 inches high, with a solid yellow background and eight inch high by one-inch wide black letters (Note: solid is defined as when being viewed from the front or rear at a nine degree angle, no light can transmit through). The sign for the front pilot/escort vehicle must be clearly legible by oncoming traffic at all times, and the sign for the rear pilot/escort vehicle must be readable and clearly legible by traffic overtaking from the rear.
An escort displaying a Slow Vehicle sign must accompany oversize/overweight vehicles unable to maintain a minimum speed of 45 mph on freeways or interstate highways. This sign must be a wood or metal panel, five feet by ten inches, on a yellow background with eight-inch high black letters, in accord with Federal Highway Administration Standard Alphabet Series B, painted with a one-inch wide stroke. The sign must be mounted on top of the escort vehicle, with the bottom edge not less than five feet above the road surface.
If the permitted vehicle is able to maintain adequate speed, but an escort is still required, the escort must display an OVERSIZE LOAD sign. Its dimensions are the same for a Slow Vehicle sign (see above). Slow Vehicle signs always take precedence over OVERSIZE LOAD signs.
Two methods of lighting are authorized by the division:
- Two AAMVA approved amber flashing lights, minimum six inches in diameter, 60 flashes per minute, mounted with one on each side of sign and illuminated at all times during operation; or
- An AAMVA approved amber rotating, oscillating, or flashing beacon or light bar mounted on top of the pilot escort vehicle, unobstructed and visible for 360 degrees with warning lights illuminated at all times during operation.
Incandescent, strobe, or diode lights may be used provided they meet the above criteria.
Travel restrictions
Daytime | Loads exceeding 14' in height, 10' in width, 105' in length, or an overhang exceeding 10' are restricted to daylight hours. Night time travel, when authorized by the Motor Carrier Division, may be permitted with marker lights indicating extreme width using amber lights front and center, and red lights to the rear. | |||
Weekend | NS | |||
Holidays | NS | |||
Visibility | An oversize vehicle or load in excess of 10' wide, 105' long, or with a 10' overhang (front or rear) may not operate when any accumulation of snow and ice on the roadway or visibility less than 1,000'. In addition, LCVs may not operate in wind in excess of 45 m.p.h. |
