FMCSA insurance file as of November 15, 2026.
Filings are the active or pending insurance policies FMCSA lists for this company; our copy refreshes nightly. Coverage amounts are not shown per policy.
From FMCSA's authority history (its current Motus system, plus the older L&I history it froze on May 14, 2026). "First granted" is the earliest grant on record; "on record since" is the earliest action FMCSA has when the grant itself is older than its electronic records. "Active since" is the latest grant or reinstatement, so a lapse that FMCSA reinstated restarts the clock.
From FMCSA's Safety Measurement System files, October 2024 to October 2026. Crash counts include crashes the carrier didn't cause. Out-of-service rates use only inspections that checked the driver or the vehicle.
Every roadside inspection in FMCSA's file for USDOT #596311: when, where, and which vehicles (type, make, VIN) the inspector recorded.
THC compares FMCSA's files every night and keeps what changed. Tracked since October 30, 2026, last compared November 15, 2026.

Motor carrier operating authority changed
Inactive → Active
Why it may matter: Authority status decides what interstate for-hire work a company may legally do.
What it doesn't show: FMCSA's daily file shows the status, not the reason (for example missing insurance, a request by the company, or an order).
Next step: Run a live check, and confirm with the company using the phone number on its FMCSA record.

Liability insurance on file changed
$750,000 → $1,000,000
Why it may matter: For-hire carriers must keep liability (BIPD) insurance on file with FMCSA to keep authority active.
What it doesn't show: The amount on file is the filing, not the full policy. It doesn't show deductibles or exclusions.
Next step: Ask for a current certificate of insurance and confirm it with the insurance company directly.

MCS-150 updated
FMCSA's file dates the update October 29, 2026
Why it may matter: Carriers must update the MCS-150 every two years. A fresh update means the fleet and contact details are recent.
What it doesn't show: The MCS-150 is filled in by the company itself; FMCSA doesn't check the numbers.
Next step: Nothing needed unless other details changed too.
