Legal Liability vs. Direct Primary
- Legal liability — pays only when you are proven negligent. Cheapest form, and what most small lots buy.
- Direct primary — pays regardless of fault, ahead of the customer's own policy. Costs 30–60% more.
- Direct excess — pays after the customer's insurer. Middle option.
The Coverage Gap Most Operators Miss
On-hook covers a vehicle while it is attached to your truck. The second the wheels touch your lot, only garage keepers responds. Carry both.
Who Requires It in Montana
- AAA, Agero, Urgent.ly, and Honk — $100k minimum on the certificate
- Montana police rotation lists
- Apartment and retail PPI property managers
- Dealership and body shop transport contracts
Not by statute in most cases, but Montana Department of Justice rotation rules and every major motor club contract require it before dispatching to you.
