What Are New Hampshire’s Legal Size Limits?
RSA 266:12 prohibits a vehicle wider than 102 inches including the load, and RSA 266:10 prohibits a vehicle taller than 13 feet 6 inches (14 feet 6 inches for manufactured housing). Past those you need a permit under RSA 266:24 and the department’s Tra 300 rules.
How Do You Get A New Hampshire Oversize Permit?
Apply in NHDOT’s electronic permitting system at nhdotpermits.org, which also posts whether oversize travel is open. The fee is $6 for an over-length, over-width or over-height permit (RSA 266:22). The rule gives the permit office up to 30 days after a complete application to decide (Tra 304.07(c)).
A single-trip permit is not issued, without supermove treatment, for a load over 15 feet wide, 110 feet long, 13 feet 6 inches high or 149,999 pounds (Tra 304.12(b)–(c)). A supermove needs extra information, such as a New Hampshire engineer’s inspection report, and over 13 feet 6 inches high or 110 feet long a physical route survey of clearances, at your expense. Roads off the state system need permission from the town or city that runs them (Tra 304.16(a)).
When Does New Hampshire Require An Escort?

No escort is needed under 12 feet wide, under 90 feet long and with under 15 feet of rear overhang, as long as the load carries its flags (Tra 304.17(b)).
When Can An Oversize Load Move In New Hampshire?
On weekdays only: Tra 304.14(h) says oversize permits are not valid on weekend days, except supermoves and buildings over 12 feet wide on their own carriage. Travel is in daylight hours around sunrise and sunset; follow the times on your permit. Overweight-only loads at normal speed are not limited by day or time.
Permits are not valid on New Year’s Day, Martin Luther King Jr. Day, Presidents Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and the day after, or Christmas (Tra 304.14(g)). When a holiday falls on a Saturday the Friday before is restricted too, and when it falls on a Sunday the Monday after is (304.14(f)). No permitted move runs in inclement weather; a load already moving exits and parks until it clears (304.14(k)).
What Signs, Flags And Lights Does New Hampshire Require?
Tra 304.15 requires fluorescent red or orange flags at least 18 inches square on the load’s extremities, four to six of them on a wide load; a yellow OVERSIZE LOAD sign at least 7 feet wide and 18 inches high with 10-inch black letters on the front of the truck and the rear of the load; and a top-mounted flashing or strobe amber light visible for 1,000 feet. Convoys are not allowed. See New Hampshire signs, flags and lights.
Where Does RouteAll Fit?
RouteAll does not issue or approve permits. Once New Hampshire issues yours, upload the PDF and RouteAll lists every road it read, so you can check them against the permit, then warns you if you leave them. One free trip every month covers up to six state permits.
