Is the windshield and equipment on a fire truck covered in our policy?

The glass breakage would be covered under the comprehensive coverage with your Comprehensive deductible applied.  If the equipment is permanently attached to the fire truck, then it is considered as part of the vehicle and the appropriate Comprehensive deductible would be applied when considering the total damage to the vehicle following an accident. If the equipment is not permanently attached to the vehicle, the coverage would be under the Inland Marine and that deductible would apply should a loss occur.
