Data collected by the Federal Motor Carrier Safety Administration is used to support the following data systems and programs:

The Motor Carrier Management Information System (MCMIS) includes five files:

• The Census File, with data collected from interstate truck and bus companies and intrastate carriers of hazardous materials, contains basic data on carrier vehicles, drivers, and commodities carried.
  
  
• The Crash File, with data collected by State and local police jurisdictions, contains basic identification data on all trucks and buses involved in fatal, injury, and tow-away crashes.
  
  
• The Inspection File, with data collected by State and FMCSA truck and bus inspectors, includes the results of roadside vehicle and driver safety inspections.
  
  
• The Compliance Review File, with data collected by FMCSA and State Safety Investigators, contains the results of safety compliance reviews conducted on motor carriers.
  
  
• The Enforcement File, with data collected from FMCSA enforcement cases against motor carriers, contains the results of closed enforcement cases against motor carriers.
  
  
• The Commercial Driver License (CDL) program is a State-based system for which all States report serious traffic safety violations of Federal Motor Carrier Safety Regulations to the truck or bus driver’s home State.
  
  
• The Drug and Alcohol Management Information System, with data collected through a sample survey of motor carriers, contains data on the percent of commercial drivers found to be violating Federal Motor Carrier drug and alcohol regulations.
  
  
• The Safety and Fitness Electronic Records System (SAFER) contains safety information on individual motor carriers, with all data entered from MCMIS files.
  
  
• The Motor Carrier Safety Fitness Measurement System (SafeStat) measures the relative (peer-to-peer) safety fitness of motor carriers with all data from MCMIS files.
