Hired auto insurance is a commercial auto coverage that protects your business when employees drive vehicles the company rents, leases, or borrows rather than owns. It pays for bodily injury and property damage claims against your business arising from accidents in those vehicles, and it sits inside a standard commercial auto policy as an endorsement or coverage symbol selection. It’s inexpensive to add and easy to forget about until a rental counter asks for proof of coverage or an accident puts the question in front of you.
What Hired Auto Coverage Pays For
The core protection is third-party liability. If someone driving a rented vehicle on company business causes an accident, the policy pays the other party’s medical bills and property repairs up to the policy limits. Most commercial contracts and vendor agreements require auto liability of at least $1,000,000 per occurrence, so businesses typically carry limits in that range.
What the liability piece does not cover is injuries to your own employees riding in the vehicle. Those claims route through workers’ compensation instead. The definition of a hired auto also excludes vehicles borrowed from an employee or from a member of an employee’s household; a car borrowed from an employee’s spouse falls into the separate non-owned auto category, not hired auto.1Sonoma County.

Physical Damage Is a Separate Piece
Liability alone won’t pay to fix or replace the rental vehicle itself. For that you need hired auto physical damage coverage, which addresses collision and comprehensive losses and requires its own endorsement. The payout is typically capped at actual cash value or the cost of repair, whichever is less, minus a deductible. Deductibles commonly mirror whatever applies to your owned vehicles, with a default around $500 if no owned vehicle on the policy carries physical damage coverage.
Even with physical damage coverage, two charges rental companies routinely bill after an accident usually fall outside the policy. Loss of use is the daily revenue the rental company loses while the damaged vehicle sits in a repair shop. Diminished value is the drop in resale price because the vehicle now has an accident on its record. Standard commercial auto policies generally exclude both, and that gap can add thousands of dollars to what you owe after a minor collision in a rental.
Hired Auto vs. Non-Owned Auto
These two coverages solve related but different problems, and confusing them leaves gaps.
- Hired auto covers vehicles your business rents, leases, or borrows from a third party. The business arranged the use of the vehicle, and the rental or lease agreement is typically in the company’s name.
- Non-owned auto covers personal vehicles that employees drive for business errands, client visits, or deliveries. The vehicle belongs to the employee or a household member, and the business never signed a rental agreement for it.1Sonoma County. Business Auto Coverage Form CA 00 01
Employers face vicarious liability when an employee causes an accident while driving for work, regardless of who owns the vehicle. Non-owned auto coverage acts as excess liability over the employee’s personal auto policy, meaning the employee’s insurer pays first and the commercial policy covers what’s left. Hired auto coverage is typically primary on the rented vehicle because no personal auto policy is in play. Most businesses that use any mix of rentals and employee-driven personal cars need both coverages active on the policy.
When Your Business Needs It
The most common trigger is employee travel. When someone flies to a conference or client site and rents a car in the company’s name, that vehicle falls squarely under the hired auto definition. Without the endorsement, the commercial policy won’t extend to the rental, and the employee’s personal auto policy may not either once the agreement is in the business’s name.
Short-term leases of specialized vehicles create the same exposure. A landscaping company leasing a dump truck for a two-week project, or a caterer renting a refrigerated van for an event season, is operating a hired auto. Underwriters price for the risk based on vehicle type, so heavier or specialized equipment costs more to cover than a passenger car.
Loaner vehicles are the scenario most businesses forget. When your company truck goes to the shop and the dealership hands you a loaner to keep operations running, that loaner is a vehicle you borrowed. It fits the hired auto definition. If your policy doesn’t carry the endorsement, you’re driving uninsured from a commercial standpoint, even though the dealership may assume you have coverage.
Should You Still Take the Rental Counter’s Waiver?
Every rental counter offers a collision damage waiver (CDW), and most business owners decline it on the assumption that the commercial policy handles everything. A CDW waives the rental company’s right to pursue you for the full replacement cost of the vehicle, plus loss of use and diminished value. Your hired auto physical damage endorsement pays only actual cash value and usually excludes those two additional charges.
If your company rents vehicles a few times a year, buying the CDW each time may cost less than an annual physical damage endorsement and closes the loss-of-use and diminished-value gaps entirely. If you rent frequently, the per-day CDW cost adds up fast, and the endorsement becomes the better deal despite its limits. In that case, budget separately for the possibility of loss-of-use and diminished-value bills after an accident.
What a Credit Card’s Rental Benefit Won’t Do
Many business credit cards advertise rental car damage protection, but the fine print matters. Most credit card CDW benefits cover only physical damage from theft or collision, not liability. They also exclude trucks, cargo vans, vehicles with open beds, and rentals longer than 31 consecutive days. If your business rents anything larger than a passenger car or minivan seating up to nine, the credit card benefit likely doesn’t apply. Because credit card coverage never includes liability, it cannot replace hired auto insurance; at best it supplements physical damage protection for passenger car rentals.
Why a Personal Auto Policy Won’t Fill the Gap
Business owners who haven’t yet bought a commercial auto policy sometimes assume their personal auto insurance covers occasional business use. Standard personal auto policies exclude coverage when a vehicle is used as a livery or delivery service, or in the business of selling, repairing, or storing vehicles. Even for uses that aren’t explicitly excluded, insurers may decline claims involving regular business activity or cancel the policy for undisclosed commercial use. Relying on a personal policy for what is clearly business transportation is one of the fastest ways to end up uninsured after an accident.
Heavy Trucks and Federal Minimums
If your business hires heavy trucks for interstate hauling, standard hired auto coverage isn’t the whole picture. The Federal Motor Carrier Safety Administration requires for-hire carriers operating vehicles with a gross vehicle weight rating above 10,001 pounds to maintain minimum liability insurance of $750,000 for non-hazardous freight. The minimum rises to $1,000,000 for certain hazardous materials and $5,000,000 for the most dangerous cargo categories, including bulk explosives and certain poisonous gases.2eCFR. Title 49 CFR 387.9 – Financial Responsibility, Minimum Levels
Carriers meeting these thresholds must also carry an MCS-90 endorsement on their liability policy.3Federal Motor Carrier Safety Administration. Insurance Filing Requirements The MCS-90 attaches to the carrier’s policy and guarantees the public can collect on liability claims even if the policy would otherwise exclude the specific circumstances of the accident. If your business occasionally hires a heavy truck for a one-off project, your standard commercial auto policy almost certainly doesn’t meet these requirements. You’d need either a motor carrier policy or written confirmation that the trucking company you’re hiring carries its own compliant coverage.
What It Costs
Premiums are based on your estimated annual cost of hire, which is the total amount you expect to spend on vehicle rentals and leases during the policy year. A company that rents a car a handful of times annually might report a cost of hire under $5,000 and pay a premium in the low hundreds. A business that keeps several leased vehicles year-round will report a much higher figure and pay correspondingly more. The rate per dollar of hire varies by vehicle type, with passenger cars carrying lower rates than heavy trucks.
On the application or renewal, you provide your best estimate of annual spend along with the types of vehicles you plan to hire. Underwriters distinguish between passenger cars, light trucks, medium trucks, and heavy equipment because each category carries different accident frequency and severity profiles.
Expect a Year-End Audit
The estimate you provide at the start of the policy year isn’t the final word. Most carriers audit hired auto coverage at the end of the policy period to compare your estimated cost of hire against actual rental expenditures. The auditor will request financial records, often including general ledgers, profit and loss statements, and receipts for vehicle rentals. If you spent significantly more on rentals than estimated, you’ll owe additional premium. If you spent less, you may receive a refund. Businesses that ignore or refuse to cooperate with an audit risk policy cancellation, which creates a visible gap for future underwriters.
Keeping a dedicated expense category for vehicle rentals in your accounting system makes the audit painless. When rental charges are scattered across project codes or employee expense reports, reconstructing the total at audit time becomes a headache that can delay the process and raise questions about accuracy.
How to Add It and Get Proof of Coverage
Adding hired auto coverage to an existing commercial auto policy is one of the simpler insurance transactions. You’ll need to provide your estimated annual cost of hire, the types of vehicles you plan to rent, and whether you want physical damage coverage in addition to liability. Your commercial agent can add the endorsement through a mid-term policy change, or you can request it at renewal. Many carriers accept these requests through their online portals.
Once the underwriter approves the change, the carrier issues a revised declarations page reflecting the new coverage symbol, updated limits, and any premium adjustment. Turnaround is typically a few business days, though some carriers process endorsements within 24 hours.
The document you’ll use most often is the certificate of insurance. This one-page summary proves to rental agencies, leasing companies, and business clients that your policy includes hired auto coverage at specific liability limits. Your agent or carrier can generate certificates on demand, and you should request one before arriving at a rental counter. Having the certificate ready prevents delays at pickup and confirms you’re protected the moment you sign the rental agreement.
After an Accident in a Hired Vehicle
The claims process starts the same way as any auto claim: make sure everyone is safe, call 911 if anyone is injured, and move the vehicle out of traffic if possible. Then gather what both your insurer and the rental company will need.
At the scene, collect the other driver’s name, address, insurance company, and policy number. Record their license plate and the make, model, and year of their vehicle. Get contact information from any witnesses and the responding officer’s name and badge number. Ask for the accident report number. Document the time, location, weather, and road conditions, and photograph the scene from multiple angles.4National Association of Insurance Commissioners. What You Should Know About Filing an Auto Claim
Call the number on your commercial auto insurance card as soon as possible to report the claim. You’ll also need to notify the rental company, which will run its own damage reporting process and will likely send you a bill for repairs, loss of use, and potentially diminished value. Your insurer will assign a claims adjuster to assess the damage and determine what falls within the policy. Keep notes on every conversation with both the adjuster and the rental company, including dates, names, and what was discussed.
If you disagree with the settlement amount, ask the adjuster for a written explanation. Most commercial auto policies include an appraisal clause that allows both sides to hire independent appraisers when they can’t agree on the value of a loss. If disputes continue, your state insurance department’s consumer services division can intervene.4National Association of Insurance Commissioners. What You Should Know About Filing an Auto Claim
