Who Needs This Permit
Any carrier or shipper moving a load or vehicle combination in New Hampshire that exceeds legal dimensions or weight thresholds set by NH DOT / highway authorities needs an oversize and/or overweight permit before travel (unless a specific exemption applies).
Typical triggers include width over 8'6", height over state legal maximum (often 13'6"–14'0" depending on corridor), length beyond legal combination limits, or axle/gross weights above posted or statutory limits.

Permit Details
Legal size and weight rules protect bridges and pavement and keep traffic safe. In New Hampshire, exceeding those limits without a valid OS/OW permit can lead to citations, forced offloading, and bridge damage liability.
Single trip vs. annual: Most TruckPermits.online OS/OW orders for NH are single-trip or short-duration permits tied to a specific route. High-frequency identical moves may qualify for other New Hampshire permit products—ask our team if you run recurring dimensions.
Conditions: Issued New Hampshire permits often restrict night travel, holiday movements, weather, pilot/escort cars, and signing/lighting. The permit document controls—drivers must read it before departure.
TruckPermits.online’s service fee covers application assistance and coordination; final NH state fees may vary with weight, distance, and permit class and are reflected in your order total where known at filing.
