Approved January 5, effective March 1. Commonwealth Automobile Reinsurers — the Massachusetts residual market — re-prices a 47,200-policyholder, $244.6M book that every carrier in the state benchmarks against. Limousine services take 15%, taxis 11%, and zone-rated long-distance haulers a steep 24.4%. The filing also raises compulsory minimum limits to 25/50/30, so even flat-rated risks pay more.
Garage liability is the lone bright spot, down 6.2%. Because CAR rates anchor the voluntary market, this filing pushes the whole Massachusetts commercial-auto floor higher for 2026.
