The short answer for New Hampshire
Loads wider than 12 ft 0 in need a pilot car in New Hampshire, and wider than 14 ft 0 in need two.
New Hampshire asks for a first pilot car at 12 ft 0 in wide. 28 of the 45 states that publish a width wait until a wider load, and 1 start earlier; 15 more match it.
One non-police escort at 12 ft wide or more (under 14 ft), 90 ft long or more, over 14 ft high, or 15 ft overhang; width over 14 ft or length 100 ft+ adds state police escorts.

New Hampshire Pilot Car FAQs
- How wide can a load be in New Hampshire before it needs a pilot car?
- New Hampshire requires the first pilot car at 12 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 New Hampshire require a height pole car?
- New Hampshire does not publish a single height at which a pole car is required in the sources we reviewed. Confirm it with NHDOT Oversize/Overweight Permit Office; permit conditions often set it per route.

- New Hampshire lists a length trigger of 90 ft 0 in for an escort. Check the permit for how many escorts a long load needs.
- Do I need New Hampshire pilot car certification?
- Escort driver certification and reciprocity rules differ by state and change often. The permit conditions from NHDOT Oversize/Overweight 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 New Hampshire'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.
