Many small businesses in Georgia depend on one or more vehicles to conduct their daily operations. A truck may be used to transport tools, a van to visit customers, or a vehicle may be necessary to make deliveries, carry materials, or move equipment.
However, using a vehicle for commercial purposes may create different risks than using a vehicle exclusively for personal activities. If an accident occurs while the vehicle is being used for business, a personal auto policy may not provide the protection the business needs.
Commercial auto insurance is designed to help cover certain risks related to vehicles used in commercial operations. Depending on the policy, it may provide protection for:
-
Vehicles owned by the business.
-
Vehicles used by employees.
-
Contractor trucks.
-
Commercial vans.
-
Vehicles used for deliveries.
-
Cars used to visit customers.
-
Vehicles that transport tools or materials.
-
Hired or non-owned vehicles, when the corresponding coverage is added.

What Is Commercial Auto Insurance?
Commercial auto insurance is a policy that may help protect a business against certain risks related to vehicles used for commercial activities.
The policy may include coverage for:
-
Liability for accidents.
-
Physical damage to the insured vehicle.
-
Authorized drivers.
-
Vehicles owned by the business.
-
Hired vehicles.
-
Non-owned vehicles.
-
Injuries to third parties.
-
Property damage to third parties.
-
Vehicles used to transport tools or materials, subject to the policy terms.
The exact coverage depends on the insured vehicles, the declared use, the drivers, the operating territory, the selected limits, and the applicable exclusions.
Why Might a Small Business Need Commercial Auto Insurance?
A business may need commercial auto insurance when a vehicle is primarily used to benefit, operate, or generate income for the business.
Examples include:
-
Transporting tools to different projects.
-
Delivering materials to a job site.
-
Making deliveries to customers.
-
Visiting properties or work sites.

Transporting commercial equipment.
-
Picking up inventory or supplies.
-
Transporting employees during a work-related activity.
-
Visiting suppliers.
-
Performing repairs or installations.
-
Transporting products for sale or delivery.
Even if the vehicle is an ordinary car or a small truck, commercial use may change how the insurance company evaluates the risk.
What Is the Difference Between Personal and Commercial Auto Insurance?
Personal Auto Insurance
A personal policy is primarily designed for private and family activities, such as:
-
Traveling to work.
-
Going to school.
-
Shopping.
-
Visiting family members.
-
Taking personal trips.
-
Driving during free time.
The policy may limit or exclude certain commercial uses.
Commercial Auto Insurance
A commercial policy is designed for vehicles used in business-related activities, such as:
-
Deliveries.
-
Transporting tools.
-
Visiting customers.
-
Construction work.
-
Repair services.
-
Transporting merchandise.
-
Installation work.
-
Maintenance operations.
-
Contractor activities.

| Regular use | Personal transportation | Deliveries, visits, transportation, or services |

| Limits | Based on personal policy | May require higher limits |
| Certificates | Generally not required | May be required under commercial contracts |

Main Commercial Auto Insurance Coverages

Depending on the contract, it may include:
-
Medical expenses for third parties.
-
Defense costs.
-
Covered settlements.
-
Covered judgments.
-
Injury claims.
Coverage is subject to the limits, exclusions, conditions, and deductibles established in the policy.

Examples include:
-
Damage to another automobile.
-
Damage to a home.
-
Damage to a fence.
-
Damage to a commercial structure.
-
Damage to a utility pole.
-
Damage to another person’s equipment.
This coverage does not necessarily pay for damage to the business’s own vehicle. Physical damage coverage may be needed to protect the business vehicle.
Uninsured and Underinsured Motorist Coverage
This coverage may help when the commercial vehicle is involved in an accident caused by a driver who:
-
Does not have insurance.
-
Has insufficient limits.
-
Cannot be identified, when the applicable coverage allows it.
Availability, limits, and conditions vary. The business should review this coverage with its insurance agent.
Collision Coverage
Collision coverage may help pay for certain damage to the commercial vehicle after a covered accident.
It may apply when the vehicle:
-
Collides with another automobile.
-
Hits an object.
-
Impacts a barrier.
-
Rolls over.
-
Collides with a structure.
This coverage is generally subject to a deductible.
Comprehensive Coverage
Comprehensive coverage may help cover certain damage that is not caused by a collision.
Examples include:
-
Theft.
-
Vandalism.
-
Fire.
-
Hail.
-
Storms.
-
Falling objects.
-
Damage caused by animals.
-
Other risks covered by the policy.
Coverage for Hired Vehicles
Hired Auto Liability may help protect the business’s liability when it uses a rented vehicle for commercial purposes.
Examples include:
-
Renting a van for a project.
-
Renting a truck during a high-demand season.
-
Using a rented vehicle to transport materials.
-
Renting a car to visit customers.
This coverage does not necessarily protect against physical damage to the rented vehicle. That protection should be reviewed separately.
Coverage for Non-Owned Vehicles
Non-Owned Auto Liability may help protect the business when an employee, owner, or contractor uses a vehicle that does not belong to the business.
Examples include:
-
An employee uses a personal car to make a delivery.
-
The owner visits a customer in a personal vehicle.
-
A worker transports tools in a personal car.
-
An employee picks up materials for the business.
This coverage generally focuses on the business’s liability and does not necessarily cover physical damage to the employee’s vehicle.
Scheduled Vehicle Coverage
Vehicles owned by the business should generally be correctly listed on the policy, including information such as:
-
Year.
-
Make.
-
Model.
-
VIN.
-
Type of vehicle.
-
Use.
-
Primary location.
-
Registered owner.
Do not assume that every newly purchased vehicle is automatically covered. Confirm the company’s requirements before using it.
Trailer Coverage
If the business uses trailers, it is important to review:
-
Whether they must be listed separately.
-
Whether they are covered while attached.
-
Whether they have physical damage coverage.
-
Whether they transport tools or materials.
-
Which limits apply.
-
Whether commercial use is included.
Cargo and Merchandise Coverage
Commercial auto insurance does not always automatically cover merchandise or property being transported.
A business may need to review additional coverage for:
-
Products.
-
Customers’ equipment.
-
Tools.
-
Materials.
-
Inventory.
-
Property in transit.
-
Goods temporarily stored.
The coverage needed depends on who owns the property and what responsibility the business has assumed.
Does Commercial Auto Insurance Cover Tools Inside the Vehicle?
Not necessarily.
Tools and equipment may require coverage such as:
-
Inland Marine.
-
Contractor’s Equipment.
-
Commercial Property.
-
Equipment Floater.
-
Coverage for property away from the business premises.
-
Coverage for equipment in transit.
Commercial auto insurance may respond to certain vehicle damage or liability claims involving third parties, but that does not mean the tools inside the truck are automatically protected.
Can a Business Use a Personal Vehicle for Work?
It may be possible, but the use must be properly disclosed.
A personal automobile used to:
-
Visit customers.
-
Make deliveries.
-
Transport tools.
-
Transport products.
-
Pick up materials.
-
Provide services.
may create commercial exposure.
The business should confirm:
-
Whether the personal policy permits that use.
-
Whether Non-Owned Auto Liability is needed.
-
Whether the driver must be disclosed.
-
Whether the vehicle is used occasionally or regularly.
-
Whether the business has a policy for the use of personal vehicles.
What Happens If an Employee Has an Accident?
If an employee has an accident while performing an activity authorized by the business, claims may arise against:
-
The driver.
-
The vehicle owner.
-
The business.
-
The employer.
-
Other involved parties.
How the insurance responds depends on:
-
The circumstances of the accident.
-
The vehicle’s use.
-
The policy in effect.
-
Who was driving.
-
Whether the driver was authorized.
-
The selected limits.
-
Applicable exclusions.
-
Relevant law.
The business should establish clear rules for employees who drive during work activities.
Requirements for Commercial Vehicle Drivers
The insurance company may request information about each driver, such as:
-
Full name.
-
Date of birth.
-
Driver’s license number.
-
State that issued the license.
-
Accident history.
-
Violation history.
-
Experience driving commercial vehicles.
-
Date of hire.
-
Type of vehicle driven.
-
Operating area.
The business must report changes in drivers and should not allow unauthorized individuals to use insured vehicles.
Young Drivers and Commercial Vehicles
Insurance companies may apply specific rules when a young driver operates a commercial vehicle.
The business should review:
-
Minimum age.
-
Required experience.
-
Type of vehicle.
-
Driving history.
-
Vehicle use.
-
Internal safety rules.
-
Insurance company requirements.
-
Customer or contractual requirements.
Not every driver automatically qualifies to operate every type of commercial vehicle.
What Liability Limits Does a Small Business Need?
There is no single limit that is appropriate for every business. A business should consider:
-
Type of operation.
-
Size of vehicles.
-
Number of vehicles.
-
Distance driven.
-
Type of merchandise.
-
Number of employees.
-
Third-party exposure.
-
Customer contracts.
-
Requirements of lessors or lenders.
-
Operations within or outside Georgia.
-
Type of business.
Some customers or general contractors may require specific limits before allowing a business to begin work.
Legal minimum limits may not be sufficient for a business that transports expensive equipment, operates in areas with heavy traffic, or has commercial contracts with customers.
Commercial Auto Insurance for Financed Vehicles
When a business finances a vehicle, the lender may require:
-
Comprehensive coverage.
-
Collision coverage.
-
Minimum liability limits.
-
A maximum deductible.
-
Listing the lender as a
lienholder. -
Proof of insurance.
-
Notice of changes or cancellation, when applicable.
Before purchasing a truck or van for the business, request an insurance quote. The cost of the policy should be included in the company’s total operating budget.
Insurance for Leased Vehicles
Under a leasing agreement, the lessor may require:
-
Specific limits.
-
Comprehensive coverage.
-
Collision coverage.
-
Listing the lessor on the policy.
-
Deductible requirements.
-
Proof of insurance.
-
Coverage for additional charges.
Carefully review the agreement and provide the exact requirements to your agent.
Certificate of Insurance for Commercial Auto
A customer may request a Certificate of Insurance, commonly called a COI, to verify that the business has active insurance.
The certificate may show:
-
Name of the insured.
-
Insurance company.
-
Policy number.
-
Effective dates.
-
Liability limits.
-
Listed coverages.
-
Certificate holder.
The customer may also request:
-
Additional Insured.
-
Primary and Non-Contributory.
-
Waiver of Subrogation.
-
Specific limits.
-
Hired vehicle coverage.
-
Non-owned vehicle coverage.
A certificate does not change the policy or expand coverage by itself. If a contract requires additional protection, the appropriate endorsement generally must be reviewed and added.
What Does Additional Insured Mean?
An Additional Insured is a person or entity that may receive certain rights under a policy through an endorsement.
A customer or general contractor may request this status when hiring a business that uses vehicles to perform services.
Additional Insured status:
-
Is not always automatic.
-
May be limited to specific operations.
-
May include exclusions.
-
May depend on the contract.
-
May apply only for a specific period.
-
May require a specific endorsement.
The business should provide the agent with the complete contract and exact requirements.
Primary and Non-Contributory
Some contracts require the business’s insurance to be:
-
Primary, so it responds first.
-
Non-Contributory, so the other party’s insurance does not contribute before the required coverage is used.
This condition should not be added merely by writing it on a certificate. It generally requires an endorsement approved by the insurance company.
Waiver of Subrogation
A Waiver of Subrogation may limit certain rights of the insurance company to recover payments from a specific party after a claim.
Some customers request this endorsement as a contractual condition. Availability depends on:
-
The policy.
-
Type of operation.
-
Insurance company.
-
Contract.
-
Business relationship.
-
Available endorsement.
How Much Does Commercial Auto Insurance Cost in Georgia?
There is no single price for all small businesses. The premium may depend on several factors.
The insurance company may consider:
-
Type of business.
-
Number of vehicles.
-
Type of vehicles.
-
Vehicle value.
-
Number of drivers.
-
Driving history.
-
Claims history.

Type of merchandise.
-
Vehicle use.
-
Liability limits.
-
Deductibles.
-
Additional coverages.
-
Business experience.
-
Insurance history.
-
Contractual requirements.
A business that uses one truck occasionally may receive a different risk evaluation than a business that operates several delivery vehicles every day.
The best way to determine the price is to request a quote based on the business’s actual operations.
Factors That May Affect the Premium
Type of Vehicle
A van, pickup truck, commercial truck, or automobile may have a different premium.
Weight and Size
Larger vehicles may present a different exposure and may have additional requirements.
Operating Radius
The company may evaluate local, interstate, and long-distance operations differently.
Driver History
Accidents and violations may affect risk evaluation.
Type of Merchandise
Transporting documents is different from transporting heavy equipment, construction materials, or high-value products.
Frequency of Use
A vehicle used every day may represent more exposure than one used occasionally.
Selected Limits
Higher limits may increase the premium but may be necessary to protect the business and satisfy contracts.
Claims History
The frequency and severity of previous claims may affect underwriting.
Number of Vehicles
A business with several vehicles may need a broader commercial policy.
