How to verify ENVIRONMENTAL MAINTENANCE SERVICES INC

  1. Verify USDOT and MC numbers match the carrier's documents. Compare the USDOT number and MC docket on this page to the numbers on the carrier's invoice, rate confirmation, or load-board listing. A mismatch between the carrier's claimed numbers and the registered legal name is the single most common red flag.
  2. Check active operating authority and insurance status. Confirm the Authority Records show at least one ACTIVE docket for the type of operation you're booking, and that the Active Insurance card lists a current BIPD/Primary policy. A revoked authority or uninsured carrier cannot legally operate.
  3. Review safety rating and SMS BASIC scores. Check the carrier's FMCSA safety rating (if any) and the SMS BASIC table. A high percentile in any BASIC category — especially Unsafe Driving, HOS, or Vehicle Maintenance — is worth investigating before tendering a load.
  4. Examine inspection and crash history. Open the Inspection History and Crash History subpages for the full record. Look for patterns: repeat OOS findings on the same unit, multiple crashes in a short window, or violations clustered in one BASIC category.
  5. Cross-reference real-time data with FMCSA SAFER. For the most current snapshot — within 24 hours of any insurer filing or authority change — click through to the FMCSA SAFER lookup. TruckCodex mirrors SAFER and L&I daily; SAFER itself reflects filings within 24 hours.

Frequently asked questions about ENVIRONMENTAL MAINTENANCE SERVICES INC

Is ENVIRONMENTAL MAINTENANCE SERVICES INC an active motor carrier? ▾
Yes. ENVIRONMENTAL MAINTENANCE SERVICES INC is registered with the FMCSA under USDOT 693501 and is currently shown as Active in the agency's Motor Carrier Management Information System (MCMIS). Active status means the carrier may legally operate, contingent on continuous insurance and authority filings.
What is ENVIRONMENTAL MAINTENANCE SERVICES INC's safety rating? ▾
ENVIRONMENTAL MAINTENANCE SERVICES INC's FMCSA safety rating is S. Safety ratings are assigned only after a formal compliance review; most carriers in the FMCSA database are unrated.
How many inspections has ENVIRONMENTAL MAINTENANCE SERVICES INC had? ▾
23 roadside inspections are on file for ENVIRONMENTAL MAINTENANCE SERVICES INC in FMCSA's MCMIS database. Each inspection is summarized in the Inspection History section below — sortable by date, state, level, and out-of-service result. Newer inspections are pulled from the FMCSA SMS data feed daily.
What is ENVIRONMENTAL MAINTENANCE SERVICES INC's out-of-service rate? ▾
ENVIRONMENTAL MAINTENANCE SERVICES INC's peak out-of-service rate is 7.7% (whichever is higher of driver-OOS or vehicle-OOS, computed from FMCSA roadside inspection data). The national averages are roughly 6.7% for drivers and 23.4% for vehicles — see the peer-context card on this page for a side-by-side comparison.
Where is ENVIRONMENTAL MAINTENANCE SERVICES INC based? ▾
ENVIRONMENTAL MAINTENANCE SERVICES INC reports its physical address to the FMCSA as 10 GRAMAR AVENUE, PROSPECT, Connecticut 06712. Carriers must file a Form MCS-150 every two years to keep their address current; an outdated address is a common compliance flag.
Does ENVIRONMENTAL MAINTENANCE SERVICES INC have valid operating authority? ▾
ENVIRONMENTAL MAINTENANCE SERVICES INC has 1 authority record on file, but none are currently active. See the Authority Records section below for the status of each docket — common reasons for inactive authority include lapsed insurance, cancelled BOC-3 filings, or revocation following safety-related actions.
How many trucks and drivers does ENVIRONMENTAL MAINTENANCE SERVICES INC operate? ▾
ENVIRONMENTAL MAINTENANCE SERVICES INC self-reports 17 power units and 15 drivers on its most recent FMCSA Form MCS-150 filing. Power-unit and driver counts come from the carrier directly and are required to be updated every two years; very large fluctuations between filings can indicate fleet changes worth investigating.
Has ENVIRONMENTAL MAINTENANCE SERVICES INC had any crashes? ▾
2 FMCSA-reportable crashes are on file for ENVIRONMENTAL MAINTENANCE SERVICES INC in MCMIS. A reportable crash is one resulting in a fatality, an injury requiring transport for medical attention, or a vehicle disabled and towed from the scene. The full crash log is on the Crashes subpage with date, state, and outcome details.

About FMCSA carrier records

Every commercial motor carrier operating in the United States is required to register with the Federal Motor Carrier Safety Administration (FMCSA) and obtain a USDOT number. The USDOT number is a permanent, unique identifier — once assigned, it stays with the carrier for life and is never reissued to another company. Carriers must update their registration every two years on Form MCS-150 to keep their address, fleet size, and operating data current.

Carrier safety data lives in FMCSA's Motor Carrier Management Information System (MCMIS): roadside inspections, crashes, out-of-service findings, and the seven Behavior Analysis and Safety Improvement Categories (BASICs) that make up the SMS scoring methodology. For-hire carriers must also hold operating authority — an MC, FF, or MX docket number — which is separate from the USDOT number and requires continuous insurance and BOC-3 process-agent filings to remain active.

TruckCodex mirrors FMCSA's public SAFER and L&I systems on a daily refresh cycle. Every record on this page reflects what FMCSA has on file. We do not edit or modify carrier data — for real-time confirmation immediately before a transaction, click through to the FMCSA SAFER lookup linked in the related records section above. Safety ratings, when present, come from formal compliance reviews; most active carriers have not been reviewed and are correctly listed as unrated.
