Commercial Auto Insurance for small businesses

Commercial auto insurance covers vehicles owned, leased, or used by a business — cars, trucks, vans, and trailers — for third-party bodily injury and property damage liability, plus optional physical-damage coverage for the vehicle itself.¹ The Insurance Information Institute publishes state-specific auto financial-responsibility laws showing that 49 states legally require some form of auto liability coverage for business-owned vehicles, with New Hampshire as the only state that allows proof of financial responsibility as an alternative to standard auto insurance (RSA 264:3).² Across Insureon's small-business marketplace, small businesses pay a median of approximately $245 per month for commercial auto, with the full annual premium range running under $375 to over $16,000 depending on vehicle type, driver count, operations, and hazard exposure.³ Personal auto policies exclude business use of a vehicle — which makes commercial auto a statutory requirement for any business with vehicles titled in the business name, transporting goods or clients, or providing company-provided vehicles to employees.

This page walks through who needs commercial auto, what the standard policy structure covers, exclusions worth understanding, how to choose limits, how it's priced, and which carriers in our coverage set are the stronger commercial auto options.

Who needs commercial auto

Any business that:⁴

• Owns vehicles titled in the business name. Personal auto policies exclude business use; the business needs commercial auto regardless of vehicle size.
• Uses vehicles to transport goods or clients. Delivery services, couriers, contractors hauling materials, transportation services.
• Has employees driving company-provided vehicles. Standard company vehicle programs require commercial auto on the business's policy.
• Operates trucking. Federal FMCSA minimum liability requirements apply to interstate trucking ($750K non-hazmat, $1M-$5M for hazmat depending on classification).

Hired and non-owned auto (HNOA) coverage is a different structure — it covers the business's liability when employees drive personal vehicles for work errands (client visits, deliveries, errands). HNOA is often packaged as a BOP endorsement or a standalone supplement; businesses without owned vehicles but with employee driving still need HNOA.

Industry-specific context: See trucking, general-contractors, electricians, plumbers, hvac, landscapers, cleaners, and restaurants (for delivery operations) for industry-specific commercial auto guidance.

What commercial auto covers

A standard commercial auto policy typically includes:¹⁴

Liability coverage (required by state law):

• Bodily injury liability — third-party injuries caused by the business's vehicle in an at-fault accident. State minimums range from $15K/$30K (most states) to $50K/$100K in others; commercial fleets typically carry $1M combined single limit minimum.
• Property damage liability — damage to other people's vehicles and property caused by the business's vehicle in an at-fault accident.

Optional coverage (not required but standard for protecting the business's own vehicle):

• Collision coverage — repair or replacement of the business's vehicle after an at-fault collision.
• Comprehensive (other-than-collision) coverage — damage from theft, vandalism, fire, flood, hail, falling objects, or animal collision.
• Medical payments or personal injury protection (PIP) — medical expenses for driver and passengers regardless of fault.
• Uninsured / underinsured motorist coverage — covers the business's occupants and vehicle when struck by an at-fault driver with insufficient coverage.

Hired and non-owned auto (HNOA):

• Hired auto liability — liability when the business rents or leases vehicles short-term.
• Non-owned auto liability — liability when employees drive personal vehicles for business purposes.

What commercial auto doesn't cover

Standard exclusions:¹

• Intentional damage — damage caused deliberately by insureds.
• Racing and prepared-course driving.
• Business use not disclosed on the application — for example, using a truck for livery (passenger transport) without a livery endorsement, or using a vehicle for delivery when rated for personal business errands only.
• Wear and tear and mechanical breakdown — covered by vehicle maintenance and equipment-breakdown coverage, not auto.
• Damage from war or nuclear incidents.
• Use of vehicles not listed on the policy — ad-hoc use of vehicles the policy doesn't schedule may have limited or no coverage.

The personal-auto exclusion of business use. Personal auto policies typically exclude business use of a vehicle beyond incidental errands. Employees using personal vehicles for regular business driving (delivery routes, client visits, sales calls) need HNOA coverage on the employer's commercial auto policy — the employee's personal auto policy often won't respond to a business-use accident.

Policy limits and how to choose them

Commercial auto limits are typically expressed as combined single limit (CSL) or split limits.

Combined single limit (CSL):

• $100,000–$500,000 CSL — common for micro-businesses with single vehicles.
• $1,000,000 CSL — the typical minimum for commercial auto for businesses with employees driving.
• $1,000,000–$2,000,000 CSL — common for standard small-business commercial auto.
• $2,000,000+ CSL — required for many enterprise client contracts and trucking operations.

Split limits (older structure, still common in some markets):

• $100K bodily injury per person / $300K per accident / $100K property damage.
• $250K / $500K / $100K.
• $500K / $1M / $250K.

FMCSA minimum for interstate trucking:

• $750,000 non-hazmat for most interstate freight.
• $1,000,000 hazmat (lower-risk hazmat classifications).
• $5,000,000 hazmat (higher-risk hazardous materials, environmental-sensitive routes).

When to go higher:

• Vehicle weight and passenger count. Trucks and vans with more weight or capacity generate higher-severity claims.
• Employee drivers vs. owner-only. Employee drivers increase liability exposure.
• Client contract requirements. Enterprise clients, construction subcontracts, and government contracts frequently require $2M+ CSL.
• Operating territory. Urban operations and high-traffic markets see higher claim severity.

Commercial umbrella applicability. A commercial umbrella policy typically sits excess of commercial auto liability — making the umbrella an efficient way to add $1M-$5M of additional coverage on top of the underlying auto limit. For fleet operations, umbrella is often the cheaper path to reaching required contract limits than raising the primary auto limit.

Cost and how to buy commercial auto

For full cost analysis with industry breakdowns, top carriers by published starting price, and 2026 benchmark data, see our commercial auto insurance cost guide.

Marketplace cost data. Insureon reports small-business commercial auto median at $245/month, with annual premiums ranging under $375 to over $16,000 depending on vehicle type, operations, drivers, and hazard class.³ Commercial auto is the most expensive of the core small-business lines on a per-vehicle basis.

What drives commercial auto price:

• Vehicle type and weight class. Heavy trucks cost more than sedans; sedans cost more than utility vehicles rated for personal use.
• Operations and radius. Long-haul trucking costs meaningfully more than local delivery; interstate operations cost more than intrastate.
• Driver count and records. Each driver on the policy affects premium; poor MVR (motor vehicle record) raises premium substantially.
• Claim history. Prior auto claims significantly affect renewal premium.
• Limits. Higher limits scale premium, though less than proportionally.
• State. No-fault states, urban states, and high-litigation states have higher premium loads.
• Use and classification. Livery (passenger transport), hazmat, and specialty transport have class-code-specific elevated premium.

• Hiscox — Hiscox does not write commercial auto. Pair Hiscox (PL, D&O, EPLI, GL) with another carrier for commercial auto.
• Simply Business — commercial auto panel placement across the 8-carrier roster.⁹

Progressive Commercial reality note. Progressive Commercial is the dominant small-fleet commercial auto writer in the U.S. market but is not currently in our 10-carrier coverage set. For commercial auto specifically, buyers seeking the broadest small-fleet option should consider Progressive alongside the carriers above; we may add Progressive to our coverage in a future research pass.

What underwriters evaluate: vehicle details (year/make/model, VIN, value), primary use classification, operating radius, driver list with MVR pulls, prior 3-5 years of auto claims, specific cargo (for trucking), interstate or intrastate operations, and any specialty classifications (hazmat, livery).

State-by-state requirements for commercial auto

Commercial auto is legally required in 49 of 50 states per state auto financial-responsibility laws.²

The New Hampshire exception. New Hampshire does not technically require auto insurance — drivers must instead prove financial responsibility under RSA 264:3. In practice, most businesses in NH carry commercial auto anyway because proving financial responsibility without insurance requires substantial deposits or surety bonds, and NH insurers write commercial auto on the same standard basis as other states.

State minimum liability limits vary:

• $15K/$30K/$5K — minimum bodily injury per person / per accident / property damage in several states.
• $25K/$50K/$25K or similar — more common commercial minimum.
• $50K/$100K/$50K and higher — some states and specific operations.

Commercial fleets typically carry $1,000,000 combined single limit as a standard minimum, meaningfully above any state statutory minimum. Client contracts, lenders financing vehicles, and federal FMCSA rules for interstate trucking all drive actual limits above state minimums.

Key state regulatory authorities:

• California Department of Insurance¹⁰ — California commercial auto market regulation.
• Florida Office of Insurance Regulation¹¹ — Florida commercial auto.
• Texas Department of Insurance¹² — Texas commercial auto, including the New Hampshire-style financial-responsibility option.
• New York State Department of Financial Services¹³ — New York commercial auto.

FMCSA interstate-trucking minimums apply to operations crossing state lines:

• $750,000 non-hazmat general freight.
• $1,000,000 hazmat (lower-risk classifications).
• $5,000,000 hazmat (higher-risk classifications, oil spill environmental response).

Frequently asked questions

Is commercial auto required by law?

Yes in 49 of 50 states per state auto financial-responsibility laws. New Hampshire allows proof of financial responsibility as an alternative, but most NH businesses carry commercial auto anyway because the alternative is impractical.²

Can I use my personal auto policy for business driving?

Usually no. Personal auto policies typically exclude business use of a vehicle beyond incidental errands. Regular business use (deliveries, client visits, sales calls) is excluded, which creates a coverage gap on a business-use accident. Commercial auto (for business-owned vehicles) or hired-and-non-owned auto (for employees' personal vehicles used for work) is required.

How much does commercial auto cost?

Insureon reports a small-business median of $245/month with annual premiums ranging under $375 to over $16,000 depending on vehicle type, operations, drivers, and claims history.³

What's hired and non-owned auto?

HNOA covers the business's liability when employees drive personal vehicles (non-owned) for business purposes, or when the business rents vehicles short-term (hired). HNOA is often packaged as a BOP endorsement or a standalone supplement.

What are FMCSA minimum requirements for trucking?

Federal FMCSA requires interstate trucking operations to carry minimum liability: $750,000 for non-hazmat general freight, $1,000,000 for some hazmat, and $5,000,000 for higher-risk hazmat and environmentally-sensitive routes.

What does combined single limit (CSL) mean?

CSL is a single total limit that covers the full combination of bodily injury and property damage per accident, rather than splitting into separate per-person and per-accident limits. $1M CSL pays up to $1M total per accident regardless of how it splits across injured parties and property damage.

Do I need commercial auto if my employees use their own vehicles for work?

Yes — through HNOA coverage. Employee personal auto policies typically exclude business use and won't respond to a business-driving accident.

Can Progressive or other non-set carriers place commercial auto?

Progressive Commercial is the dominant small-fleet commercial auto writer but is not in our current 10-carrier coverage set. Buyers seeking broad commercial auto options should consider Progressive and specialty commercial auto carriers alongside the carriers in our coverage set.

Does New Hampshire really not require auto insurance?

Technically correct — NH allows proof of financial responsibility under RSA 264:3 as an alternative to auto insurance. In practice, most NH businesses carry commercial auto because the alternative requires substantial deposits or surety bonds that are impractical for most small businesses.²

Related policies

Commercial auto pairs with several related lines:

• General liability — covers on-premises and operations liability that auto excludes.
• Business owner's policy (BOP) — often includes hired-and-non-owned auto as an endorsement for businesses without owned vehicles.
• Commercial umbrella — sits excess of commercial auto liability as well as GL and employer's liability; cheap way to add $1M-$5M.
• Workers' compensation — covers employee injuries including those in auto accidents while driving on the job.
• Commercial property — covers property at a business location; auto covers the vehicle itself.
