Primary liability protects everyone else. These two coverages protect you: your equipment and the drives that happen outside a dispatch. They're where owner-operators either save themselves or quietly leave a six-figure asset uninsured.

Physical damage: coverage for YOUR truck and trailer

Physical damage (PD) is the comp-and-collision policy for your own equipment:

  • Collision covers your truck hitting something or rolling over: another vehicle, a bridge abutment, an icy ditch.
  • Comprehensive (other-than-collision): fire, theft, vandalism, hail, a deer, a tree limb through the hood.

Each scheduled unit, tractor and trailer separately, gets its own insured value and premium. Nobody makes you carry PD once the truck is paid off; your lender absolutely will while there's a lien. But "not required" and "not needed" are different things: if a paid-off truck burns and you can't replace it out of pocket, you didn't save money by skipping PD. You bet the business and lost.

ACV vs. stated value: the part that decides your claim check

How the truck gets valued at claim time matters more than almost anything else on the policy:

  • Actual cash value (ACV) pays the market value of your truck at the time of loss, depreciation included. Fair, but in a volatile used-truck market it may be less than you expect, and possibly less than you owe.
  • Stated amount / stated value policies list a value you chose. Here's the trap: most stated-amount forms pay the lesser of the stated amount or ACV. Overstate the value and you've paid premium on a number you'll never collect. Understate it and you've capped your own claim.

The fix is boring: insure the truck for what it's honestly worth, and revisit the number at renewal instead of letting it ride for five years.

Deductibles and add-ons

You'll choose a deductible per unit, the classic trade of premium against out-of-pocket. Worth asking about while you're at it: towing and cleanup after a covered loss, rental reimbursement/downtime coverage, and gap-style protection if you owe more than the truck is worth. Wrecker and recovery bills on a heavy truck are their own kind of sticker shock.

Non-trucking liability & bobtail: the off-dispatch gap

If you're an owner-operator leased to a motor carrier, the carrier's primary liability covers you while you're working under their authority: under dispatch, hauling their loads. But the truck doesn't stop being a 17,000-pound liability when the load is delivered.

  • Non-trucking liability (NTL) covers liability when you're driving not under dispatch and not in the business of trucking: heading home after dropping the trailer, driving to the shop on your day off, running personal errands in the tractor.
  • Bobtail liability is the related, often-confused term: technically it covers driving without a trailer attached, regardless of dispatch status. Many people (and some policies) use the terms loosely, but the legal difference matters. Deadheading under dispatch with no trailer is a bobtail situation but not a non-trucking one, and which policy responds depends on the wording and the lease.

Who needs it: leased owner-operators, almost always. Most lease agreements flat-out require NTL and physical damage, because the motor carrier's policy is built to cover business use, not your Saturday drive. If you run under your own authority with your own primary liability, you generally don't need NTL; your primary policy is yours around the clock (confirm how your policy treats personal use rather than assuming).

How it differs from primary liability: same type of protection, bodily injury and property damage to others, but a much narrower trigger and a much smaller price. NTL is cheap precisely because it only responds when you're off the clock. That also means it's not a substitute for primary liability, and claims adjusters will absolutely dig into dispatch records to determine which policy owes the loss.

The takeaway

  • Physical damage = your equipment. Value it honestly, know whether you're ACV or stated amount, and don't drop it just because the note is paid.
  • NTL/bobtail = your off-dispatch driving when you're leased on. Required by most leases, cheap, and the difference between a covered fender-bender and a personal lawsuit.

How McClure helps

We see the same two mistakes on repeat: trucks insured at values nobody updated since purchase, and leased operators who assume the motor carrier "has them covered" everywhere. Send us your lease and your current declarations page. We'll tell you exactly which policy responds in which situation, price the gaps, and make sure the value on your truck is one an adjuster will actually pay.
