Not every claim against a towing business involves a vehicle in motion. General liability is about the rest of the operation.
What general liability addresses
General liability addresses certain claims of bodily injury or property damage connected to business operations, such as an incident at your premises. It does not replace commercial auto liability.
Questions to ask your agent
Bring these to a licensed agency. They are prompts for a conversation, not a checklist of what you must buy.
Which parts of my operation fall under general liability rather than auto liability?
Does the policy address my yard, office and customer waiting area?
Do any contracts I sign require general liability in a particular form?
