What is Sewer and Water Main Contractors Auto?

Sewer and water main contractors auto insurance is a type of commercial auto coverage designed for businesses that install, repair, or maintain sewer and water systems. Because these contractors use specialized vehicles and equipment on the job, they face unique risks on the road and at worksites.

  • Comprehensive coverage – for non-collision events like fire, theft, or vandalism
  • Medical payments – for injuries to the driver or passengers
  • Uninsured/underinsured motorist – protection if the other driver doesn’t have enough coverage
