State Data

Data-driven safety systems are vital to informing decisions that improve safety on the Nation’s roads—FMCSA relies on the States for accurate and comprehensive data on eligible crashes and inspections to focus resources to further reduce crashes. We can’t do it without you.

Each month, States are rated on their reporting of safety data—this page provides States with a robust resource to view their ratings and measures, and learn how to improve data quality performance.

Select your State from the dropdown menu below to view your State's results.

Your rating is

Good (100-90)

Fair (89-80)

Poor (79-0)

83% of your State's evaluated fatal crash records were reported to MCMIS as compared to the number of fatal crash records in FARS. These crashes occurred in calendar year 2018. Your rating is fair because the number of MCMIS records as a percentage of FARS records is between 80%-89%. Learn how this rating is calculated.

NOTE: INSUFFICIENT DATA: State has < 10 FARS records AND MCMIS as a % of FARS is < 89%

Talk with your State's FARS Analyst to ensure that you have all the records you should in MCMIS. If needed, reach out to your DQ Specialist for help to connect with your FARS Analyst.

Data Source: FARS records and MCMIS crash records representing interstate, intrastate, and non-motor carriers and includes only large trucks involved in crashes that occured within the calendar year.

How this rating is calculated

The Fatal Crash Completeness Measure evaluates a full calendar year of fatal crash records to determine your State’s rating. A record is evaluated if the date of the crash event—not the date of upload to FMCSA—falls within that calendar year. (This differs from the other State Safety Data Quality (SSDQ) measures, which evaluate a rolling 12-month period.) This evaluated calendar year is the most recent year for which Fatality Analysis Reporting System (FARS) data is available to the public. The evaluation period is updated when the next full year of FARS data becomes available.

This measure evaluates fatal crash records representing interstate, intrastate, and non-motor carriers, and includes only large trucks. It determines a rating based on a comparison of the number of State-reported fatal crash records in the Motor Carrier Management Information System (MCMIS) to the number of your State’s crash records in FARS.

FARS is the national database of fatal motor vehicle crashes maintained by the National Highway Traffic Safety Administration (NHTSA).

If the percentage of State-reported records in MCMIS as compared to the number in FARS is

90% or more, the rating is GOOD
Between 80% and 89%, the rating is FAIR, unless the number of FARS records reported is less than 10, in which case the rating is INSUFFICIENT DATA.
Less than 80%, the rating is POOR, unless the number of FARS records reported is less than 10, in which case the rating is INSUFFICIENT DATA.

Why this matters

Complete fatal crash reporting helps FMCSA prioritize carriers for interventions that pose the greatest safety risk.
