An Act relative to peer-to-peer car sharing

This bill establishes a legal framework for peer-to-peer car sharing in Massachusetts, defining key terms like "shared vehicle owner" (the car owner using a platform) and "shared vehicle driver" (the renter). It requires peer-to-peer platforms to assume liability for bodily injury and property damage during the sharing period, with minimum insurance coverage matching standard auto insurance requirements (sections 34A-34R of Chapter 90). Platforms must ensure all parties (owners, drivers, or themselves) maintain primary insurance that covers sharing use without exclusions, and they must cover claims if insurance lapses or disputes arise over vehicle control or return locations. The law specifically excludes traditional rental companies from these rules and clarifies that platforms cannot shift liability to other insurers before their coverage applies.
