When Maryland requires a pilot car, how many, and when a height pole car is needed. Set by MDOT State Highway Administration (SHA) Hauling Permit Office.
MD, reviewed October 2026
The short answer for Maryland
Loads wider than 13 ft 0 in need a pilot car in Maryland, and wider than 14 ft 0 in need two. A height-pole escort is required at 14 ft 6 in tall.
Maryland asks for a first pilot car at 13 ft 0 in wide. 16 of the 45 states that publish a width wait until a wider load, and 24 start earlier; 4 more match it.
One escort for permit moves more than 13 ft wide, more than 85 ft long, 14 ft 6 in high or more (pole vehicle), or over 60 tons; two escorts at 14 ft wide or more or 140 ft long or more; police escort at 16 ft wide or more.

Maryland Pilot Car FAQs
- How wide can a load be in Maryland before it needs a pilot car?
- Maryland requires the first pilot car at 13 ft 0 in wide and a second at 14 ft 0 in wide. Loads up to the 8 ft 6 in legal width travel without a width escort.
- When does Maryland require a height pole car?
- A height-pole escort is required at 14 ft 6 in tall and over in Maryland. The pole is set just above the load so the escort driver finds low wires and structures first.
- Is a pilot car required for long loads in Maryland?
- Maryland lists a length trigger of 85 ft 0 in for an escort. Check the permit for how many escorts a long load needs.
- Do I need Maryland pilot car certification?
- Escort driver certification and reciprocity rules differ by state and change often. The permit conditions from MDOT State Highway Administration (SHA) Hauling Permit Office state who may escort a load, so confirm certification and insurance requirements there before you book an escort.
- Where do the pilot car numbers on this page come from?
- They are taken from Maryland's published permit rules and statutes, reviewed in October 2026, with the source links listed on this page. Where a figure could not be confirmed it is marked as not confirmed rather than estimated.
