Listed for drivers in and around Boston, MA, these 24 shops work on medium and heavy duty trucks. What each one says about fleet accounts, road service, inspections and hours comes from its own website; ratings and quotes come from public reviews.
8 of the 24 shops sit inside Boston; the rest come from other towns and are shown with their own city. Truck shops need land, long approaches and highway access, so they end up on the edge of town. Drivers already plan around that.
