MAINE MOTOR VEHICLE INSPECTION MANUAL MAINE STATE POLICE TRAFFIC SAFETY UNIT 20 STATE HOUSE STATION REVISED 01/31/2022 TELEPHONE 624-8935 MAINE DEPARTMENT OF PUBLIC SAFETY MAINE STATE POLICE CHAPTER ONE-MAINE MOTOR VEHICLE INSPECTION RULES EXECUTIVE SUMMARY The Motor Vehicle Inspection Program has been in existence for over 85 years. The primary goal of this safety program is the regulation and enforcement of the state’s 2,700 inspection stations and over 8,000 licensed inspection technicians. The Maine Motor Vehicle Inspection Manual includes the formal rules governing many facets of the program, as well as reference guides and other documents that may be helpful for the automotive professional. These rules include the application process for licensure, the responsibilities of inspection technicians and stations, and the safety inspection standards and criteria for the inspection of a motor vehicle, motorcycle, commercial vehicle, school bus, or trailer. Prior to this effort, the last revision of the rules was in 2012. Since that revision, automotive technology and the industry have seen considerable change and growth. Representatives from the industry and our personnel have noted numerous inconsistencies, omissions, obsolete material, and required additions or clarifications within the current manual. Several legislative actions and subsequent statute changes needed to be reflected in rule. The current rules are a product of a project that began in early 2018. Once the clear need for amended rules was identified, the Maine State Police Motor Vehicle Inspection Unit in concert with the Motor Vehicle Advisory Board, spent countless hours modifying the manual to reflect our dedication to safety related inspection items and did away with rules that lacked a true safety nexus. Resources utilized for this work include; Federal Motor Vehicle Safety Standards, Federal Motor Carrier Safety Regulations, applicable Maine statute, National School Bus Standards, National Highway Traffic Safety Administration studies, American Association of Motor Vehicle Administrators (AAMVA) studies and Model Policy on Periodic Safety Inspections. The final rule, as adopted represents the product of this process and the input from people from a wide variety of groups with interest and expertise in the areas of automotive technology, safety, and law enforcement. The overall spirit and intent of these proposed rules is to update and clarify terminology, simplify language, clarify program practices and policies wherever possible, and to reflect current industry norms and practices. It was also our intent to minimize any fiscal impact to current licensees, and to be cognizant of the realities faced by many smaller businesses. It is with this realization that we have endeavored to ‘grandfather’ existing licensees where possible, and to use an incremental approach to making change within the industry. Although a complete review of the rule is recommended for thorough understanding, the following represents a summary of the changes in rule: DEFINITIONS: 􀀹 Updates language and terminology throughout the manual. 􀀹 Definition of caster angle updated to the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle, other vehicle or a vessel, measured in the longitudinal direction. 􀀹 Added the definition of rake angle as the angle in degrees of arc which the headstock of the motorcycle is inclined when compared against a vertical line drawn perpendicular to the ground. 􀀹 Definition of tint station updated to a licensed inspection station or a business engaged in automotive glass treatment, tinting or certifying of window tint. SUMMARY: Added to the summary at the beginning of all inspection sections the following: 􀀹 All vehicles inspected in the State of Maine must have met all applicable Federal Motor Vehicle Safety Standards, Environmental Protection Agency poll
