KARST CORPORATION
Doing business as SERIOUS BUSINESS TRUCKING
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, (708) 675-0276, not a number from an email or load board.
- Check that the MC number you were given is MC850066.
- 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.

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.

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 Illinois average covers 195,384 vehicle and 387,932 driver inspections of all Illinois-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 ↗

"Share" is this company's mix of violations; the Illinois column is the mix across all Illinois-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 KARST CORPORATION
What does KARST CORPORATION's operating authority allow?
MC850066: Motor carrier (may haul regulated property for hire).
Which information about KARST CORPORATION 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 KARST CORPORATION?
Confirm the authority and insurance on the Motus record for USDOT 2460348. Call the company back on the phone number on file, (708) 675-0276, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC850066, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
