Every fiber, cable, and low voltage contractor uses vehicles for work — company work vans, bucket trucks, splice trailers, drill rigs, and employees’ personal pickups carrying tools between jobs. Personal auto policies exclude all of this. This guide covers what commercial auto insurance actually covers, how to insure specialty equipment (bucket trucks, drill rigs, splice trailers), the critical Hired & Non-Owned Auto endorsement (CA 99 33) that every prime requires, and how to structure coverage for multi-state operations.
Personal Auto vs Commercial Auto — The Coverage Cliff
Personal auto policies contain a business use exclusion. If you use a vehicle for fiber contracting work — even a personal pickup carrying a splicer between jobs — and something goes wrong, the personal auto policy denies coverage.
A fiber contractor drives their personal pickup to a residential FTTH install carrying an OTDR, splicer, and supplies. They’re in an at-fault accident. The personal auto carrier discovers the vehicle was en route to a job, denies coverage under the business use exclusion, and the contractor personally pays the third-party damages. This scenario destroys small contractors regularly. Commercial auto or, at minimum, Hired & Non-Owned Auto is essential.
The line between personal and commercial isn’t always the vehicle — it’s the use. Even personally-owned vehicles used for business purposes require commercial coverage or non-owned auto endorsement.
Owned, Hired & Non-Owned Auto — Three Coverage Categories
Commercial auto coverage splits into three categories based on who owns the vehicle:
Vehicles titled to your business — work vans, service trucks, bucket trucks, drill rigs, and splice trailers. Standard commercial auto coverage: liability, physical damage (comp & collision), medical payments, uninsured motorist.
Vehicles rented or hired for business use — rental cars, rented bucket trucks, rented drill rigs. Covered through the Hired Auto endorsement. Bridges the gap between rental company’s limited coverage and your business exposure.
Vehicles not owned by you or your business but used for business purposes — typically employees’ personal vehicles driven while on company time. Non-Owned Auto endorsement protects the business when an employee has an accident driving a personal vehicle for work.
Most commercial auto policies write Hired and Non-Owned Auto as a single endorsement (CA 99 33). This is what carrier primes and hyperscaler GCs specifically require on your COI — almost every commercial subcontract mandates it.
Bucket Trucks, Splice Trailers & Drill Rigs — Specialty Coverage
Specialty fiber contracting vehicles have unique insurance considerations beyond standard commercial auto:
Bucket trucks need commercial auto liability for the truck chassis PLUS coverage for the bucket boom, which is typically insured through inland marine or specific equipment coverage on the commercial auto policy. If you rent bucket trucks, verify your Hired Auto coverage extends to the specialty equipment and any operator exposure.
Splice trailers combine a towed unit (commercial auto liability for the trailer) with valuable interior equipment (splicers, OTDRs, computers, splitters). Interior contents are typically covered under inland marine or contractors equipment coverage rather than commercial auto. Confirm the towing vehicle has adequate liability and physical damage coverage for the trailer, and separate contents coverage for the equipment.
Horizontal directional drill rigs are titled as vehicles but have specialty equipment mounted (the drill, mud system, tracking gear). Insurance is split: commercial auto for road transit liability and physical damage, contractors equipment for the drill and mud system operating exposure. Some carriers write both in a combined policy; others require separate policies. Rental drill rigs need Hired Auto AND rented equipment coverage.
If employees use personal pickups to carry tools or drive between jobs, the exposure is covered by Non-Owned Auto. However, if the employee’s personal auto insurer discovers business use, they may non-renew or refuse to pay a claim. Consider paying for a small commercial auto endorsement on the employee’s vehicle or reimbursing them for their commercial-endorsed personal policy.
Multi-State Fiber Crews & Commercial Auto
Fiber contractors operating across state lines face specific commercial auto considerations:
- Registration state — vehicles must be registered in their home state, but must be permitted for use across states
- Minimum limits vary — each state sets minimum liability limits; $1M CSL exceeds all state minimums but confirm any state-specific mandates
- UIM/UM — uninsured and underinsured motorist requirements vary. Some states require specific limits
- Personal Injury Protection (PIP) — some states (Florida, Michigan) require PIP coverage. Confirm your commercial auto policy includes it where required
- Interstate crossings — DOT regulations apply to certain vehicle classes crossing state lines. Verify DOT compliance if you operate heavier trucks
Fiber contractors mobilizing crews to jobs 200+ miles from home base — common in West Texas, the Panhandle, rural fiber grants — benefit from Hired Auto coverage for rental vehicles used at the remote job site. Cheaper than moving your own fleet and better protected than employees driving personal vehicles long distances.
What Primes Require on Commercial Auto
| Prime | Auto Requirement |
|---|---|
| Zayo (Avetta) | $1M CSL with Owned, Hired & Non-Owned Auto; Zayo Group LLC as Additional Insured |
| Crown Castle (now Zayo) | $1M CSL with HNOA; Crown Castle entities as AI |
| AT&T Fiber sub | $1M CSL with HNOA; AT&T Services Inc. as AI |
| Hyperscaler data center GC | $1M CSL with HNOA; some campuses require $2M CSL for larger scopes |
| BEAD-funded prime | Grant-specific; typically $1M CSL with HNOA |
| Municipal ROW permits | Varies by city; $1M CSL common; some require higher |
Every carrier prime and hyperscaler GC will verify Hired & Non-Owned Auto endorsement (CA 99 33) is on your COI. Its absence is the #2 most common commercial auto COI rejection (after limit mismatch).
What Commercial Auto Costs for Fiber Contractors
| Fleet Profile | Typical Annual Premium |
|---|---|
| 1-2 vehicles (van + pickup), $1M CSL, single state | $2,500 – $5,500 |
| 3-5 vehicles, $1M CSL, multi-state | $5,000 – $12,000 |
| Fleet with bucket trucks, $1M CSL, multi-state | $10,000 – $28,000 |
| Fleet with drill rigs and splice trailers | $18,000 – $50,000+ |
| Add HNOA endorsement to any of above | $200 – $1,500 additional |
Premium drivers: vehicle count, vehicle types (specialty vs standard), driver MVRs (motor vehicle records), states of operation, prior claims, and radius of operations. Contractors with clean driver records save 20-30%. Contractors with two or more at-fault accidents in the last 3 years pay 40-100% more.

Yes. Personal auto excludes business use. Any vehicle used for fiber contracting work needs commercial auto coverage OR Hired & Non-Owned Auto coverage.
Coverage for rented vehicles (Hired) and employee-owned vehicles driven for business (Non-Owned). Endorsement CA 99 33 combines both. Required by virtually every carrier prime and hyperscaler GC.
Commercial auto liability and physical damage for the truck chassis, plus specialty equipment coverage for the boom. Rented bucket trucks need Hired Auto coverage.
No. Personal auto excludes business use. Even carrying tools between jobs in a personal pickup can void personal auto coverage in a claim.
