For this reason, it is necessary to ensure that you understand and comply with these requirements in your state. The following is a list of inspection requirements for each of the 50 states in the United States.

Types Of Car Inspection

There are three basic types of car inspection that you might have to undergo depending on the requirements in your state. They are:

  • VIN Inspection: The aim of this inspection is to verify that the VIN on your car matches your ownership document.
  • Safety Inspection: Here, different systems in the vehicles are checked to ensure that it conforms to safety regulations.
