State trucking associations, other trucking groups urge against liability insurance hike A coalition of more than 60 trucking-related associations penned a letter this week to the House Committee on Transportation and Infrastructure to discourage members from voting for an increase in the existing minimum liability insurance coverage required for trucking companies. The coalition of 62 associations includes more than 20 state trucking associations, several agriculture associations and more. “An increase in insurance requirements is wholly unnecessary, would do nothing to improve highway safety, and would have a severe negative impact on truckers, farmers, and manufacturers by significantly increasing their operational costs,” the letter states.
