Nashua, NH Parking Rules: Commercial Vehicle Restrictions (2026)

Nashua's commercial-vehicle parking rules combine an explicit citywide ban on parked tractor-trailers with the general on-street parking framework in Chapter 320 (Vehicles and Traffic). NRO Section 320-67 (Article XII) provides: 'It shall be unlawful for any tractor-trailer-truck, the tractor alone or the trailer alone to be left parked or stationed at any time, except during the actual loading or unloading of materials therefrom, on any public street or way in the City.' The exception is narrow and limited to the period of 'actual loading or unloading,' meaning a tractor-trailer cannot be staged, dropped, or stored on the street at any other time. For non-tractor-trailer commercial vehicles - box trucks, work vans, contractor trucks - NRO 320-78 (Article XIII, Night Parking) controls overnight: 'It is unlawful for an operator of any vehicle to park the vehicle for a period longer than two hours between 12:00 midnight and 6:00 a.m., daily, on any public way in the City where overnight on-street permit parking is not allowed,' with the alternative on designated permit streets being a $10/year overnight permit (capped at 550 permits citywide). RSA 265:69 applies to all vehicles, including commercial vehicles: no stopping, standing, or parking 'on a sidewalk,' 'within an intersection,' 'on a crosswalk,' 'within 15 feet of a fire hydrant,' 'within 20 feet of a crosswalk at an intersection,' 'within 30 feet upon the approach to any flashing signal, stop sign, or traffic control signal,' or 'within 20 feet of the driveway entrance to any fire station.' NRO Section 320-67 reinforces and supplements RSA 265:69 with the same 15-foot hydrant distance (minimum fine $50) and the driveway rule (no stationing in front of a driveway or within 2 feet of either side, $50 fine increasing to $60 after seven days, plus towing fees). Downtown Nashua's metered Zones I, II, III, and IV (Zone I: 9 a.m. to 9 p.m. enforced except Sundays, 2-hour limit; Zone II: 9 a.m. to 7 p.m. enforced except Sundays, 3-hour limit; Zone III: 9 a.m. to 6 p.m. enforced weekdays; Zone IV: $2.00/hour first three hours, $4.00/hour thereafter) apply to commercial as well as passenger vehicles. New Hampshire commercial-vehicle weight and dimension limits are at RSA 266; over-the-road operations are bound by those state limits citywide.
