Which document is necessary for a vehicle inspection in New Hampshire?

For a vehicle inspection in New Hampshire, the vehicle registration is essential because it serves to identify the specific vehicle that is being inspected. The registration document contains important details such as the vehicle's make, model, year, and Vehicle Identification Number (VIN), all of which are crucial for ensuring that the vehicle meets the safety and emissions standards required by the state.

Having the registration allows the inspection station to verify that the vehicle is legally registered for use on public roads, which is a prerequisite for passing the inspection. While a driver's license and proof of insurance are important for operating a vehicle and legal compliance, they are not required to conduct the inspection itself. The title of the vehicle, while an important document for ownership, is not necessary for the inspection process to be completed.
