No risk signals found
How risk signals workNothing in the FMCSA record matched our risk signals. That is not a guarantee, and it does not confirm who you are talking to; follow the checks below.
No cargo cover filed with FMCSA
Green means the FMCSA record shows it. It does not confirm who you are talking to, or that a policy covers your specific load.
What to verify next
- Confirm authority and insurance on the official Motus record ↗. Safety record: SAFER ↗.
- Call back on the number on file, (720) 689-8011, not a number from an email or load board.
- Check that the MC number you were given is MC1512884.
- Ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
Insurance on file
Liability (BI&PD) pays for injury and damage to other people and property; it does not cover the freight. Cargo insurance covers the freight. FMCSA only requires cargo filings from household goods carriers and freight forwarders, so most carriers file none: ask for a cargo certificate that fits your load. No cargo cover filed with FMCSA.
| Type | Docket | Layer | Insurer | Coverage | Effective | Status |
|---|---|---|---|---|---|---|
| Liability (BI&PD) | MC1512884 | Primary | Great West Casualty Co Policy GRT16106A · BMC-91X | $1,000,000 | Feb 6, 2024 | Active |
Source: FMCSA Motus · Oct 19, 2026. Identical filings repeated in the FMCSA data are shown once; a filing listed under two dockets is one policy, not extra coverage. Coverage is the maximum amount filed with FMCSA, not the full policy.
Confirm current filings: Motus record ↗ and ask the insurer for a certificate naming you as holder.

How these rates are calculated
Period: Oct 19, 2024 – Oct 19, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The Colorado average covers 19,011 vehicle and 32,893 driver inspections of all Colorado-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗
Violations in FMCSA's SMS last 24 months
8 violations counted in FMCSA's Safety Measurement System (SMS), 0 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 9 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 2026 window. The SMS count comes from FMCSA's own monthly SMS snapshot, which uses its own 24-month window and only the violations it scores. Both are FMCSA figures; they measure different things.

"Share" is this company's mix of violations; the Colorado column is the mix across all Colorado-based carriers, so you can see which kinds of problems stand out. A high count partly reflects fleet size and how often trucks are inspected.

Questions about ROCK TOWING LIMITED
What does ROCK TOWING LIMITED's operating authority allow?
MC1512884: Motor carrier (may haul regulated property for hire).
Which information about ROCK TOWING LIMITED is old or missing?
There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe.
What should I verify before booking ROCK TOWING LIMITED?
Confirm the authority and insurance on the Motus record for USDOT 4015070. Call the company back on the phone number on file, (720) 689-8011, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1512884, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
