Bobtail Insurance vs Non-Trucking Liability: Which Do You Need?
Bobtail and NTL are often used interchangeably but they cover different situations. Both apply when your truck is not under dispatch, but bobtail specifically covers the tractor without a trailer attached — NTL covers broader non-business use. Most owner-operators leased to a carrier buy one non-trucking policy; your lease says which wording it requires.

Which Is Right for You?
Choose Bobtail Insurance if:
- You only drive your tractor without a trailer occasionally
- Your lease agreement specifically requires bobtail
- You need the narrowest/cheapest coverage option
Choose Non-Trucking Liability (NTL) if:
- You use your truck for personal errands or commuting
- Your lease agreement specifies NTL (most common)
- You want broader coverage for non-dispatch situations
The Most Common Mistake
Thinking you're covered by the motor carrier's insurance when driving off-dispatch. The carrier's primary liability only covers you when actively dispatched on a load. The moment you're off-dispatch — driving home, running errands, even moving your truck between terminals — the carrier's policy doesn't respond. You need bobtail or NTL (or both) to fill that gap.
Frequently Asked Questions
Is bobtail insurance the same as non-trucking liability?
No. They're similar but cover different scenarios. Bobtail specifically covers a tractor operating without a trailer. NTL covers any non-business use of the truck. Most carriers use NTL as the broader default, but many lease agreements still require 'bobtail' as a legacy term meaning the same thing. Read your lease carefully — sometimes 'bobtail' in a lease agreement actually refers to NTL.
Do I need both bobtail and NTL insurance?
Usually you only need one. Most modern policies combine bobtail and NTL into a single 'non-trucking liability' policy that covers both scenarios. Check your specific lease agreement to see which term it uses.
How much does bobtail/NTL insurance cost?
Much less than primary liability, because it only covers off-dispatch driving. The price depends on the truck, where it's garaged, your driving record and the limit your lease asks for, so we quote it on your details rather than guess.
Who sells bobtail and NTL insurance?
Many commercial trucking insurers write NTL, either as its own policy or added to a physical damage policy. Full Coverage quotes it with the markets we're appointed with and compares the wording against your lease.
