New Jersey dropped the safety portion of inspection in 2010. What remains is the emissions inspection every two years, which is free at New Jersey Motor Vehicle Commission inspection centers and a small fee at private inspection facilities.
Rules change. Verify the current New Jersey requirements with the state DMV or environmental agency before you go. This guide reflects the program as of 2026.
