Does commercial auto insurance cover my chipper while it's being towed?

The trailer may be covered under commercial auto, but the chipper itself (the equipment) is typically covered under inland marine. Verify that both the trailer frame and the mounted equipment are insured — they may be on different policies.

How much does commercial auto cost for a bucket truck?

Commercial auto insurance for a bucket truck typically costs $3,000-$6,000 per year, depending on the vehicle value, liability limits, driver records, and geographic location. The mounted boom and bucket may require separate inland marine coverage.

Do I need DOT insurance for my tree service trucks?

If your vehicles have a GVWR over 10,001 pounds and cross state lines, you need a DOT number and may need to file proof of insurance. Vehicles over 26,001 pounds GVWR require Form MCS-90 and typically need $750,000-$1,000,000 in liability limits.

What is hired and non-owned auto coverage?

Hired auto covers vehicles you rent or borrow for business use. Non-owned auto covers liability when employees use their personal vehicles for business purposes. Both are essential for tree services where employees regularly use personal trucks.

How do driver records affect my commercial auto premium?

Driver records are one of the most significant rating factors. Each at-fault accident adds 15-40% to the affected driver's portion of the premium. DUI/DWI convictions can make a driver uninsurable on commercial auto. Run MVRs on all drivers annually.

Best Commercial Auto Insurance for Tree Fleets (2026)

Tree service companies depend on their vehicles — pickup trucks, bucket trucks, chip trucks, flatbed trailers, and equipment haulers are the backbone of daily operations. Commercial auto insurance for tree service fleets must account for the unique risks of hauling heavy equipment, towing wood chippers, operating aerial lifts on public roads, and navigating residential neighborhoods with vehicles that are significantly larger and heavier than standard commercial trucks.

The best commercial auto programs for tree service fleets in 2026 provide comprehensive coverage that includes liability, collision, comprehensive (fire, theft, weather), uninsured/underinsured motorist, and hired/non-owned auto. Liability limits should be at least $1 million combined single limit (CSL), though many commercial and municipal clients now require $2M or higher. If your fleet includes vehicles with a gross vehicle weight rating (GVWR) over 26,000 pounds, you may need to meet DOT insurance requirements and file Form MCS-90 or BMC-91.

Pricing for commercial auto varies significantly by fleet size, vehicle types, driver records, and geographic location. In 2026, expect to pay approximately $1,200-$3,000 per vehicle per year for a standard tree service truck, $3,000-$6,000 for a bucket truck, and $800-$1,500 for a utility trailer. Companies with drivers who have clean MVRs (motor vehicle records), no at-fault accidents in the past three years, and commercial driver's licenses pay less. Younger drivers (under 25) and drivers with violations substantially increase premiums.

One often-overlooked coverage for tree service fleets is hired and non-owned auto insurance. If any employee ever uses their personal vehicle for business purposes — even running to the supply store — your commercial auto policy needs hired/non-owned auto coverage. Without it, an accident in a personal vehicle on company business creates a coverage gap. Similarly, if you rent vehicles for temporary needs, hired auto coverage extends your liability protection to those rentals.

Trailer coverage is another area where tree services commonly have gaps. Chippers, stump grinders, and log trailers are typically insured under inland marine rather than commercial auto. However, the trailer frame itself (the physical trailer unit) may need to be scheduled on your auto policy. Confirm with your agent exactly where your trailer coverage begins and ends — many claims are denied because the trailer was not properly scheduled on any policy.
