Hampton, New Hampshire regulations require all heavy haul operations to comply with the New Hampshire Department of Transportation (NHDOT) guidelines as well as local ordinances administered by the Hampton Department of Transportation (HAMDOT).

Heavy haul permits are required for any load exceeding 11 feet in width, 15 feet 0 inches in height, or 155,339 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Hampton, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid the Hampton Canal and the vicinity of Hampton Civic Center, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

New Hampshire law mandates escort vehicles for any load exceeding 17 feet in width or 14 feet 6 inches in height. When traveling through Hampton, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Hampton Department of Transportation requires a minimum of 36 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Hampton.

Permit applications in Hampton must be submitted through the NHDOT's online permitting system. Carriers should be prepared to provide comprehensive vehicle specifications, proposed routes, and transport schedules.

Applications must include certified weight tickets, dimensional diagrams, and route surveys. For loads that may impact traffic flow in Hampton, a traffic management plan may also be required as part of the application process.

Hampton has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Hampton Spring Exhibition and the the Hampton Arts Convention, which may impact routing and scheduling.

Certain neighborhoods, such as Hampton Center and areas around Hampton College Campus, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.

The base permit fee for an oversize load in New Hampshire is $40, with additional fees for super heavy loads (over 200,000 lbs) ranging from $150 to $350 depending on the complexity of the move.

For movements within Hampton, Hampton Department of Transportation may charge additional fees for city-specific permits, which can range from $75 to $500 or more for particularly complex routes or those requiring extensive coordination with city agencies.
