Chapter 12-0 Massachusetts Vehicle Check Program * Conveniently located Motorist Assistance Centers (MACs) have opened across the state to provide emission repair guidance to motorists, technical assistance to repair technicians, help with getting vehicles "ready" for testing after emissions repairs, vehicle evaluations for repair waivers and economic hardship extensions and vehicle testing quality assurance. * A new toll-free Massachusetts Vehicle Check Motorist Hotline (866-941-6277) can help you find an inspection station and registered emission repair shop, and can provide advice and referrals when vehicles fail their inspections, as well as other inspection-related information. Hours of Operation are 7:00 a.m. to 5:00 p.m. Monday through Saturday, with extended hours (until 8:00p.m.) on Tuesdays and Thursdays. 10/08 12:5
