Liberty Mutual describes underwriters tailoring solutions to industry, fleet, location, and vehicle use. A transportation operator seeking authority can ask Harper what proof it can provide for the quoted policy, while giving Liberty Mutual the same carrier class, routes, and vehicle details for underwriting. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [7](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet") ### Liability and Vehicle-Damage Coverage Harper’s transportation page distinguishes commercial-auto liability for accidents and third-party injuries from separate physical-damage coverage for collision and comprehensive losses to vehicles. Liberty Mutual’s commercial-auto page names liability and physical damage alongside bodily injury and uninsured motorists, and describes tailoring by vehicle use. Buyers should compare the liability and vehicle-damage sections separately, including the scheduled vehicles and any different deductibles.
