The Complete Guide To Bobtail Insurance

Bobtail insurance is a specialized type of trucking coverage that protects you when operating a truck without a trailer.

If you run a commercial trucking business, your primary liability policy typically covers you while hauling cargo. But that coverage may not extend to periods when you’re driving without a trailer — commonly referred to as “bobtailing.”

Bobtail liability insurance fills that gap. It applies when a truck is being operated without a trailer, such as when returning from a delivery or traveling between jobs.

What Is Bobtail Insurance?

Bobtail insurance is a type of liability coverage designed for trucks operating without a trailer attached. It helps cover third-party injuries or property damage if you’re at fault in an accident during that time.

This coverage is often used by owner-operators who are leased to a motor carrier. In many cases, a motor carrier’s insurance only applies while a load is being hauled under dispatch. Once a delivery is complete, coverage may lapse, leaving the driver exposed while driving without a trailer.

Bobtail insurance is typically added as an endorsement to a commercial truck insurance policy and is intended to cover these gaps between hauls.

What Bobtail Liability Insurance Covers

Coverage typically applies only in specific situations — such as when you’re driving between jobs or after completing a delivery — and may depend on your lease agreement or dispatch status.

Most bobtail policies include:

• Bodily injury liability: Covers medical expenses, rehabilitation costs, or legal claims if you injure another person in an accident
• Property damage liability: Pays for repairs or replacement if you damage someone else’s vehicle or property
• Legal defense costs: Helps cover attorney fees, court costs, and settlements related to covered third-party claims

What Bobtail Liability Insurance Doesn’t Cover

Bobtail liability insurance is limited in scope and is designed to fill a specific coverage gap. It does not apply in many common trucking scenarios.

It typically does not cover:

• Accidents while hauling a trailer: Coverage generally ends once a trailer is attached, even if it’s empty
• Injuries to you or your employees: These are typically covered under workers’ compensation or occupational accident insurance
• Damage to your own truck: Physical damage coverage is required to repair or replace your vehicle after an accident
• Personal (non-business) use: Driving off-duty for personal reasons is usually excluded; non-trucking liability coverage is designed for this scenario
• Lost income or downtime: Business interruption or downtime coverage is needed to replace income if your truck is out of service

Do I Need Bobtail Liability Insurance?

Bobtail liability insurance is designed for commercial truck drivers who operate without a trailer, typically between loads or after completing a delivery.

Whether you need it depends on how you’re contracted and when your motor carrier’s insurance applies. In many cases, a carrier’s policy only covers you while you’re under dispatch.

You may need bobtail liability insurance if:

• You’re an owner-operator leased to a motor carrier: Coverage may not apply when you’re not actively hauling a load
• You operate under someone else’s authority: Your carrier may not cover you during non-dispatch driving without a trailer
• Your lease agreement requires it: Some motor carriers mandate bobtail liability as part of their contract
• You want protection during coverage gaps: It can help cover liability risks when your primary policy doesn’t apply

Bobtail Liability Insurance VS Non-Trucking Liability Insurance

Bobtail liability and non-trucking liability insurance are often confused, but they apply in different situations.

• Bobtail liability insurance covers you when operating a truck without a trailer for business-related purposes, such as driving between loads or returning from a delivery
• Non-trucking liability insurance covers you when using your truck for personal, non-business purposes, regardless of whether a trailer is attached

Whether you need one or both depends on how and when you use your truck.

Key Differences

• Use case:
  • Bobtail: Business-related driving without a trailer
  • Non-trucking: Personal, off-duty driving
• Dispatch status:
  • Bobtail: May apply when not under dispatch (depending on your lease)
  • Non-trucking: Only applies when not under dispatch
• Trailer attachment:
  • Bobtail: Typically requires no trailer attached
  • Non-trucking: May apply with or without a trailer, depending on the policy

In some cases, insurers offer unladen liability insurance, which combines elements of both coverages. Availability and terms vary by provider, so it’s important to review policy details carefully.

Additional Types Of Liability Insurance

Bobtail liability insurance only covers a narrow set of scenarios. To fully protect your trucking business, you’ll likely need additional policies that address other risks.

Common types of liability coverage include:

Coverage needs vary based on your operation, contracts, and state requirements. Review your policy structure carefully or work with a licensed agent to identify any gaps.

How Much Does Bobtail Liability Insurance Cost?

Bobtail liability insurance is typically added as an endorsement to a commercial truck insurance policy, rather than purchased as a standalone policy.

Costs vary based on factors such as your driving history, location, type of operation, and coverage limits. In many cases, bobtail liability is relatively low-cost compared to primary liability coverage, but premiums can vary by insurer.

As a general benchmark, some policies may start around $30 to $50 per month for $1 million in liability coverage. However, rates can be higher depending on risk profile and policy structure.

Accidents while operating without a trailer do occur, and liability exposure can still be significant. Evaluating coverage needs alongside cost can help ensure you’re adequately protected.

Where To Find Bobtail Liability Insurance

Bobtail liability insurance is typically available through insurers that specialize in commercial trucking coverage. Working with a provider or agent familiar with trucking regulations can help ensure your policy aligns with your contract and operating needs.

How to Buy Bobtail Liability Insurance

Most drivers follow a similar process when purchasing coverage:

• Identify your coverage needs: Review your lease agreement and determine when your motor carrier’s insurance applies
• Gather business and driver information: This may include your CDL, driving history, vehicle details, and operating authority
• Compare quotes: Evaluate multiple insurers based on coverage terms, exclusions, and pricing
• Purchase and add coverage: Bobtail liability is usually added as an endorsement to your existing policy

Many national insurers and specialty brokers offer commercial truck insurance, including bobtail liability coverage. Availability, pricing, and policy terms vary, so it’s important to review details carefully before choosing a provider.

Other Insurance Policies Truckers Need

Bobtail liability insurance only covers a narrow set of scenarios. Most trucking businesses rely on a combination of policies to stay fully protected.

Common coverages include:

• Primary liability insurance: Required coverage that pays for third-party injuries or property damage when operating with a trailer
• General liability insurance: Covers non-driving risks, such as injuries on your premises or certain legal claims (e.g., advertising injury)
• Physical damage coverage: Pays to repair or replace your truck and equipment after accidents, theft, or other covered events
• Motor truck cargo insurance: Covers loss or damage to freight while in transit
• Uninsured/underinsured motorist coverage: Helps cover costs if you’re hit by a driver with little or no insurance
• Reefer breakdown coverage: Covers losses related to refrigeration unit failure or temperature-related cargo damage

Final Thoughts

Bobtail liability insurance fills a specific gap in commercial trucking coverage. If you operate a truck without a trailer — especially outside of dispatch — it can help protect you from liability exposure that may not be covered by your motor carrier’s policy.

Whether you need it depends on your contract, how you operate, and when your primary coverage applies. Reviewing those details can help ensure you’re not left uninsured between loads.
