Built for underwriting. CSA scores tell you a carrier's roadside history. The Exposure grade tells you how a file plays after a crash: the litigation risk no other score prices.

Broker Selection Risk
If you tender a load to this carrier: your negligent-selection exposure
Montgomery v. Caribe Transport II (2026) let negligent-selection claims proceed against brokers. A broker or shipper that tendered a load to Lone could own that choice. These are the public red flags a reasonable vetting process would have surfaced first.
- Unrated: no compliance review on fileNo federal rating exists, so a broker must do more of its own vetting.
- Vehicle out-of-service rate above the national average27.3% vs 21.3% national.
- Driver out-of-service rate above the national average7.1% vs 5.5% national.

Why this grade
12 open findings · ranked by litigation exposure weight
A driver who is not medically certified is, by regulation, not qualified to operate a CMV. Plaintiff's counsel frames every mile driven after the lapse as a knowing dispatch of an unqualified driver: direct support for negligent entrustment and a punitive-damages hook.
The pre-employment full query is a federal precondition to letting a driver perform safety-sensitive functions. Its absence is the cleanest possible negligent-hiring exhibit: the carrier put a driver on the road without confirming she was eligible. Reads terribly to a jury.
An overdue annual query on a driver with a prior Clearinghouse violation is a retention problem with teeth. Plaintiff argues the carrier had actual notice of a drug/alcohol violation and failed to keep monitoring: close to willful for punitive purposes.
Stacked on the missing Clearinghouse query, the absent pre-employment drug test makes the negligent-hiring case nearly self-proving. Two independent gating requirements skipped for the same new hire.
The lapsed annual MVR review is the standard opening move in a negligent-retention case. A modest audit item, but in litigation it lets plaintiff argue the carrier stopped watching the driving record of a driver who is still on the road. The gap between regulatory severity and exposure is the whole point.
An out-of-service vehicle returning to operation without certified repairs is direct evidence of an unfit-equipment claim. Plaintiff pairs it with the maintenance file to argue the carrier prioritized uptime over safety.
A lapsed 396.17 inspection on the same unit that just failed roadside compounds the equipment-fitness narrative. Two independent records pointing at the same truck is exactly the pattern plaintiff's reconstruction expert looks for.
Open hours-of-service violations paired with unassigned driving feed a fatigue theory and suggest records that don't reconcile. Plaintiff's expert uses unassigned drive time to argue the carrier can't account for who was behind the wheel.
