i have one truck and i want to get another one next year and jump right into commercial work i might get 2 next year and then have three total. What kind of insurance would i need for commercial work.Is there a certain type of plowing insurance or do i just tell my agent a certain amount of coverage. I want the right insurance but i also dont want to get sued. Will i need insurance to cover other subcontractors or will they need to cover themselves.
