Auto Liability vs General Liability for Trucking: What's the Difference?
Auto liability covers accidents while driving. General liability covers accidents that happen while not driving — at your terminal, at a customer's loading dock, at a truck stop. Both are essential for trucking operations, and they never overlap.
Side-by-Side Comparison
| Auto Liability (BIPD) | General Liability (GL) | |
|---|---|---|
| When it applies | While truck is driven or being operated | Premises, operations, products (not driving) |
| Required by FMCSA | Yes ($750K min, often $1M) | No (required by shippers/contracts) |
| Typical cost per truck | $4,000-$8,000/year | $600-$1,500/year |
| Example claim | Truck rear-ends another vehicle on highway | Worker slips on oil at your terminal |
| Example claim 2 | Truck damages a bridge | Contaminated load causes shipper loss |
| Includes MCS-90 endorsement | Yes (federal filing) | No |
| Covers loading/unloading | While truck is moving only | Yes (stationary operations) |
Which Is Right for You?
Choose Auto Liability (BIPD) if:
- You operate any commercial vehicle on public roads
- FMCSA authority requires BMC-91 filing
- You haul for-hire freight
Choose General Liability (GL) if:
- You have a terminal, yard, or warehouse
- Shippers require GL in their contracts
- You do any loading/unloading work
- You want coverage for completed operations
The Most Common Mistake
Assuming auto liability covers your business premises and operations. It doesn't. The moment someone is injured at your terminal, or your yard dog damages a customer's trailer, or you're sued for a completed operation — auto liability doesn't respond. You need GL. Most trucking operations need BOTH auto and general liability, and they should be bundled with the same carrier when possible for administrative simplicity.
Frequently Asked Questions
Is general liability required by FMCSA?
No. FMCSA only requires auto liability (BIPD) with the MCS-90 endorsement. However, shippers, brokers, and many contracts require GL. Most motor carriers carry at least $1M GL because without it, shippers won't do business with you.
Can I bundle auto liability and general liability in one policy?
Yes — and you should. Most commercial trucking insurers offer combined auto + GL programs, often with a premium discount. This also simplifies claims handling since both policies respond to the same event.
Does general liability cover cargo damage?
No. Cargo damage is covered by motor truck cargo insurance, which is separate from both auto and general liability. GL does not cover cargo.
How much general liability do I need?
$1,000,000 per occurrence / $2,000,000 aggregate is standard for motor carriers. Larger fleets or higher-risk operations often carry $2M/$4M. Umbrella policies above $1M primary are common.
