General Pilot cars Requirements

1.  Pilot cars must be furnished by the permittee as set forth in the permit and in accordance with this section. A pilot car must be either a passenger car or a truck with not more than two axles, a manufacturer’s gross weight rating of not more than 16,000 pounds and a width of at least 60 inches and must not exceed the legal limits of size and weight.

2.  The operator of a pilot car shall maintain sufficient distance from the escorted vehicle depending on the speed, traffic, road and weather conditions to allow for timely and safe notification of the driver of the escorted vehicle and other drivers to stop, slow or pass as necessary. If an escorted vehicle is required, pursuant to NAC 484D.640, to stop off the roadway to allow other traffic to pass, the operator of the pilot car shall:

  • Assist the driver of the escorted vehicle to stop the vehicle as far off the roadway as practicable; and
  • Direct traffic in order to maintain safe and efficient traffic movement.

3.  In addition to the requirements of subsections 1 and 2:

A pilot car must precede an escorted vehicle if:

  1. The overhang of the load exceeds 25 feet in front of the vehicle;
  2. The height of the load exceeds 15 feet 6 inches;
  3. The width of the load exceeds 12 feet and travel is on a highway with two or three lanes; or
  4. The width of the load exceeds 16 feet.
  5. If the height of the load exceeds 15 feet 6 inches, the pilot car must also be equipped with a clearance pole.

A pilot car must follow an escorted vehicle if:

  1. The overhang of the load exceeds 25 feet behind the vehicle;
  2. The length of the load exceeds 110 feet or, if the vehicle is equipped with one or more mechanically steered rear axles, 120 feet; or
  3. The width of the load exceeds 14 feet.

4.  The permittee shall ensure that pilot cars are properly equipped and that the operators of the pilot cars required pursuant to the provisions of the permit are briefed and trained as to their responsibilities. Failure of the operators to warn and direct traffic properly is a violation of the permit.

5.  A pilot car must not be loaded or equipped in any manner that impairs its traffic safety function or public recognition of its traffic safety function. Each pilot car must be equipped with:

  • For a lead pilot car for a load over 15 feet 6 inches in height, a clearance pole.
  • Signs, visible in the front and rear, with black letters that are at least 10 inches high of 1 5/8-inch minimum stroke on a yellow background. The signs must read “OVERSIZE LOAD” or “OVERSIZE” and must be mounted above the roofline. The signs must be neat, clean and mounted securely. The signs must be displayed while escorting a vehicle and be removed promptly upon the arrival of the escorted vehicle at its final destination.
  • Two flashing or rotating amber lights mounted above the roofline to either side of the “OVERSIZE LOAD” or “OVERSIZE” sign or one flashing or rotating amber light mounted above the roofline which is visible from a minimum of 500 feet in all directions. The permittee must obtain the appropriate permit for the amber lights from the Nevada Highway Patrol pursuant to NRS 484D.185.
  • An identification placard fixed to each side of the pilot car which is visible from 50 feet during the day and which states the name and telephone number of the individual or company providing the pilot car service.
