Trucking companies are required to purchase liability insurance in case a driver in their employ causes a collision. The minimum amount of liability insurance that a trucking company must purchase is $750,000 for interstate general freight motor carriers. For hazardous-material haulers, the minimum is between $1 million and $5 million. While this may seem like a lot of money, truck accidents can cause permanent injuries and deaths to drivers in Denver, Steamboat Springs, Greenwood Village and surrounding areas. Financial recovery options for truck accident victims
