Does primary liability cover bobtailing?

It depends. If you have your own authority, your primary policy generally covers all business-related driving including bobtailing between loads. If you are leased onto a carrier, their policy only covers you while under dispatch. Off-dispatch bobtailing requires separate bobtail or NTL insurance.

Do I need bobtail insurance if I have my own authority?

Possibly. While your primary liability covers business driving, personal use of your truck (driving home, running errands) may not be covered. Review your policy's personal use exclusions to determine if you need additional coverage.

Can I drive without insurance while bobtailing?

No. Operating any commercial motor vehicle without proper insurance is a federal violation under FMCSA regulations and can result in fines, out-of-service orders, and personal liability for any damages in an accident.

What happens if I have an accident while bobtailing without coverage?

You would be personally liable for all damages, injuries, and legal costs. This could mean hundreds of thousands of dollars in out-of-pocket expenses. Your CDL could also be at risk, and you may face FMCSA penalties for operating without insurance.

Is Bobtail in Your Primary Policy?

Understanding Primary Liability

Primary liability insurance is the foundation of commercial trucking coverage. The FMCSA requires minimum liability coverage of $750,000 for general freight carriers and $1,000,000 for hazmat carriers under 49 CFR Part 387.

Primary liability covers you while performing business activities for your motor carrier — picking up loads, delivering freight, and repositioning under dispatch. But the critical question is: what happens when you are NOT under dispatch?

Own Authority vs Leased On

Own Authority Carriers

If you have your own MC authority, your primary liability policy is YOUR policy. It generally covers you at all times while operating your commercial vehicle for business purposes — including bobtailing between loads.

However, even own-authority carriers may have coverage gaps during purely personal use of their truck. Read your policy carefully.

Leased Owner-Operators

If you are leased onto a motor carrier, the carrier's primary liability covers you ONLY while under dispatch performing work for that carrier.

Once you complete a delivery and are released from dispatch, the carrier's policy typically stops covering you. This is when you need bobtail insurance or NTL.

When Primary Covers Bobtailing

You have your own authority and are bobtailing to pick up your next load
You are under dispatch and bobtailing between a drop-off and your next pickup
You are repositioning as directed by your carrier or dispatcher
Your lease agreement specifically includes bobtail coverage

When You Need Separate Coverage

You are leased on and have been released from dispatch
You are driving your truck for personal errands (grocery store, home)
You are bobtailing home after your last load of the week
Your carrier's policy explicitly excludes off-dispatch bobtailing
You are between carriers or temporarily without a lease

Common Coverage Gap

The most dangerous gap occurs when a leased owner-operator drops their last load on Friday, gets released from dispatch, and drives home bobtailing. The carrier's primary liability has ended, and if you do not have bobtail or NTL coverage, you are driving uninsured.

How to Check Your Policy

Do not assume your coverage includes bobtailing. Take these steps to verify:

1Review your lease agreement — look for language about when coverage begins and ends
2Call your motor carrier's safety department and ask specifically about bobtail coverage
3Request a copy of the carrier's Certificate of Insurance (COI) and read the endorsements
4Ask your insurance agent whether your personal policy covers off-dispatch driving
5Check whether your carrier requires you to carry NTL or bobtail insurance

Coverage Gaps to Watch For

Even if you have bobtail or NTL insurance, gaps can exist. The most common gap is between the moment you are released from dispatch and when your personal coverage activates. Some policies have specific exclusions for:

Driving to get fuel (considered business activity by some insurers)
Driving to a maintenance shop (may be excluded as business-related)
Repositioning without explicit dispatch orders
Using your truck to tow personal vehicles or equipment

Read the full breakdown of covered and excluded activities in our NTL coverage scenarios guide.

Cost of Adding Bobtail Coverage

Bobtail insurance costs between $30-$60 per month for most owner-operators. NTL insurance runs $40-$80 per month. Compared to the financial devastation of an uninsured accident, this is a minimal investment.

Pro Tip

Many insurance companies offer bundle discounts when you add bobtail or NTL to your existing commercial auto policy. Ask your agent about bundling to save 10-15% on premiums.
