An Act relative to primary insurance

This bill updates Massachusetts laws regarding insurance and leasing for motor vehicles rented on a mileage basis, such as through "drive-it-yourself" systems. It requires lessors to ensure their odometers accurately record distance traveled and prohibits them from knowingly deceiving renters about mileage or leasing vehicles to drivers under the influence of alcohol or drugs. Additionally, the bill establishes a clear order for insurance coverage, making the renter's or operator's liability insurance primary over the lessor's insurance to satisfy financial responsibility requirements. These changes aim to clarify liability rules and ensure accurate billing for vehicle rentals based on distance traveled.
