When Are Pilot Cars Required in South Carolina

A pilot car (escort vehicle) is required when:

  • Length: Length is tricky in South Carolina. Call the DOT for the correct information. Leave your comments below for others, please.
  • Width: From 12′ to 14′ in width will require 1 front pilot car (escort vehicle) on 2-lane roads. 14′ to 16′ in width will require 1 front and 1 rear pilot car (escort vehicle) on all roads in the state. If your shipment is over 16′ in width, you will be required to have 3 pilot cars (escort vehicles) 1 front, 1 rear, and 1 police escort in the rear.
  • Height: It all depends on your routing. You could be required to have a pilot car (escort vehicle) with a height pole the entire trip if you are 13′ 7″  (seriously). Please share your expertise with others below.
  • Weight: If you are approved for weight and maintain the minimum speed requirements, the South Carolina DOT permit office will probably not require you to have a pilot car (escort vehicle).
  • Overhang: If you’re pulling a 48′ or a 53′ (just to clarify) extended trailer and you have less than 15′ of overhang, you can probably get away with flagging or amber lighting your shipment instead of a rear pilot car (escort vehicle). Anything over the 15′ mark and forget it; you will be required to have a pilot car (escort vehicle).

Superload Information in South Carolina

We have the following information available on superloads:

As far as length goes, you can get some play as long as your routine keeps you away from historic areas. Width is the same thing with traffic density and population considered. Height is big trouble with the South Carolina DOT. You must always have a pilot car with you if you are over 16′ in height. Count on a complete route survey for shipments over the 16′ in height, and remember that they won’t let you travel ANY route where the clearance is less than the required 6″ overage in height. If you’re 18′ in height, the obstruction on the proposed route needs to be a minimum of 18′ 6″ in height, or you’re going to have delays in getting your permit. Weight is a severe issue if you want to cross over ANY bridges, so if your shipment is over 130,000 lbs in overall gross weight, get ready for bridge studies and time delays. Our suggestion: examine routing alternatives. Overhang is a rare issue, but you will have trouble when it comes up, and you want to overhang over 15′. That is the case anytime you want to exceed the basic rule, which is more than 1/3 of the overall shipment length; you just don’t do it as it’s too dangerous, and the South Carolina DOT knows it.

Permitted Oversize Load Travel Times and Restrictions in South Carolina

The one-half hour after sunrise and one-half hour before sunset rule applies. Travel is permitted Monday through Saturday, with no travel permitted on Sundays. It’s possible to approve Sunday travel, but the basic rule is “no travel on Sundays.” Your travel permit will be stated if you are allowed to travel on a Sunday.  You may not travel on the following holidays:
  • New Years day
  • Independence Day
  • Labor Day
  • Memorial Day

You may not travel past noon on the day before the holiday and until after noon on the day after the holiday.

If you’re 16′ in width or over, on Saturdays, you are only permitted to travel between 9 AM and 3 PM, with no travel before or after permitted in any locations.

Pilot Car Certifications in South Carolina

Pilot car (escort vehicle) certifications & requirements:

The South Carolina DOT is pretty relaxed on pilot cars. You must have the proper banner/sign stating “OVERSIZE LOAD” or “WIDE LOAD” displayed prominently on the top of the vehicle, in front of lead vehicles, or rear of chase vehicles. You must have a flashing or strobing amber light on the top of the vehicle that is visible from 360 degrees from a distance of no less than 500′. You must have a CB radio or 2-way communication device and communicate with all drivers working on your shipment. You are required to have your headlights turned on while working.

NOTE: It is only our professional opinion that pilot cars also have a minimum of the additional items but not required:  2 – 5 pound fire extinguishers type A, B, and C, a paddle sign with the word “STOP” on one side and “SLOW” on the other with dimensions of no less than 18″ in diameter with a minimum of 6″ letters. A red safety-colored flag with a handle no less than 18″ square, 3 reflective emergency road triangles or 18″ traffic cones, 8 burning road flares, 2 OVERSIZE LOAD banners (yellow with black lettering), and a safety colored (red, orange, yellow or lime green) vest, jacket or shirt (used while directing traffic).

Oversize Load Signs in South Carolina

Truck, trailer, and shipment required signs, banners, and flags:

Amber lights: You must have 1 rotating or strobing rear amber light on any vehicle shipping a load over 12 inches. Flags in safety-colored orange or red with a minimum length in any direction of 12″ must be mounted on the 4 outermost corners of the entire shipment. Banner signs stating “OVERSIZE LOAD” or “WIDE LOAD” must be placed on the rear and front of the overall shipment.
