Law Enforcement

State and local law enforcement agencies are vital partners in helping IDOT in Driving Zero Fatalities to Reality! The department has compiled valuable information and resources (see tabs below) to better serve the needs of state and local law enforcement entities.


Roadside Safety Check.jpgIDOT's Bureau of Safety Programs and Engineering disseminates federal funds for local communities and state agencies to conduct highway safety counter-measures aimed at reducing highway crashes and resulting deaths, injuries, and property damage. Highway Safety Program Grants ("Section 402") are designed to help state agencies, counties, and communities initiate programs to address traffic safety related problems and generally to promote traffic safety on our roadways.

State Police.jpgAll grant projects, except state agency projects, run parallel with the federal fiscal year, October 1 through September 30. State agency projects run on the state fiscal year, July 1 through June 30. If you are interested in applying for a Highway Safety Grant, please visit the Traffic Safety Grants website.


IDOT uses motor vehicle crash information for a number of critical services including, crash data analyses, safety program design, and roadway engineering design with the ultimate goal of preventing fatalities or injuries on Illinois roadways. For more information, please visit the Crash Reporting web page.

In addition to crash reporting, IDOT collects and compiles data for the Traffic Stop Study. For more information on this study, please visit the Traffic Stop Study (Reporting and Results) webpage.

IDOT also evaluates each highway safety project with enforcement components such as: Local Alcohol Program (LAP) and Sustained Traffic Enforcement Program (STEP) using crash and citation data provided by local police departments. For a complete list of forms used for Highway Safety Grants, please visit the Forms page on the Traffic Safety Grants website.
