Insights into Total Commercial Auto Premium Written in New England
The six New England states together reported $2.93 billion in total commercial auto direct written premium, reflecting the scale and concentration of this line across the region. Massachusetts remains the clear anchor of the New England marketplace with $1.43 billion, accounting for nearly half of all commercial auto premium written in the region. Connecticut follows as the second-largest market with $711.1 million, while Maine ($245.6 million) and New Hampshire ($232.9 million) form the region’s mid-sized tier. Rhode Island ($192.4 million) and Vermont ($112.7 million) round out the list as the smallest commercial auto markets in New England.
What is apparent is that market concentration is high across the region, with the top 10 groups accounting for more than half the market share in each of the six states. It is also noteworthy that many regional carriers remain strong in key states. For example, regional insurer Arbella has a strong presence in this marketplace not just in Massachusetts, but also in Rhode Island and Connecticut. Similarly, Boston-based Safety remains dominant in its home marketplace of Massachusetts as well as in New Hampshire while MMG demonstrates regional strength in Maine, New Hampshire and Vermont.
