Operating Hours, Restricted Travel, and Holiday Restrictions
In New Hampshire, trucks can travel until one-half hour before sunrise to one-half hour after sunset on all five weekdays. For loads that fall within the dimensional limits, there are no weekend or holiday restrictions. Additionally, being overweight is not restricted when it comes to travel time.
Some specific state areas have their own restrictions that must be kept in mind. For instance, travel is restricted between 7-9 am and 3-6 pm in Manchester. There is no travel during any of the major holidays. This applies to any weekends that fall within holidays as well.
Signs, Flags, and Lights Requirements
Signs, flags, and lights may be required when moving oversize loads or superloads for the safety of others on the road.
Signs
A sign stating “Oversize Load” is required to be on the front and back of any oversize vehicle.
Flags
All load extremities that surpass 4 inches in one area must have a 12-inch square red flag mounted on top of the area. In addition, when that four-inch mark is surpassed on the back of the vehicle, one flag will be required for an overhang less than 2 inches wide, and two flags will be required for an overhang exceeding 2 inches.
Lights
In the state of New Hampshire, there are no load-specific light requirements or general light requirements.
Obtaining a permit
New Hampshire single trip travel permits are valid for up to 5 days and must be in possession when entering the state. Annual permits may depend on the vehicle in question. These authorizations are issued from the Permit Office, must stay in the vehicle, and accompany the yearly permit.
