Commercial auto coverage for Westby business vehicles
When a personal auto policy stops covering business driving, what Montana requires, and how Westby businesses insure vans, trucks and crews.
Commercial auto liability is mandatory for business vehicles in Montana, with minimum limits set by state law and published by the Montana Office of the Commissioner of Securities and Insurance.
Westby, Montana has about 162 residents, and carriers price its businesses on trade, payroll and revenue rather than on the town itself.
Small businesses in Westby compare against a national median of $45 a month for general liability - $538 a year in 2026 policy data.
Every state sets minimum auto liability limits, and most contractors carry well above them because a work vehicle accident with an injured third party is the single most expensive claim a small trade business can face. Check current Montana minimums with the Montana Office of the Commissioner of Securities and Insurance before quoting.
Personal auto policies exclude business use - deliveries, job-site runs, hauling tools. If a vehicle works for the business, it needs commercial auto coverage, and if employees drive their own cars on business errands, hired and non-owned coverage fills that gap. State minimum liability limits apply to commercial vehicles the same as personal ones; the Montana Office of the Commissioner of Securities and Insurance publishes the current requirements.

Common questions
Is business insurance required by law in Montana?
Two lines can be legally required: workers' compensation once you reach the state employee threshold, and commercial auto liability for business vehicles. General liability is not state-mandated, but leases and client contracts routinely require it.
What makes premiums go up the most?
Trade risk class, payroll size, revenue, claim history and coverage limits - roughly in that order. A single recent claim can move pricing more than every discount combined, which is why deductible choices matter.
What is the difference between general liability and a BOP?
General liability covers harm you cause to others - injuries and property damage. A business owner's policy (BOP) adds coverage for your own property - gear, inventory, premises - plus business interruption, at a median $83 versus $45 per month.
Does an LLC need insurance too?
Yes - the LLC protects your personal assets from business liabilities, but the business's own assets stay exposed. Insurance pays claims; the LLC just keeps them away from your house. Most owners carry both.
Do I need workers' comp if I only use subcontractors?
It depends on the state and on whether the subs carry their own coverage - several states count uninsured subcontractors as your employees for comp purposes. Verify with the Montana Office of the Commissioner of Securities and Insurance before assuming you are exempt.
