Traffic Safety

The Illinois Department of Transportation (IDOT) is dedicated to “Driving Zero Fatalities to a Reality.” A safe transportation system greatly reduces tragic human loss, as well as the economic costs of crashes. Illinois’ transportation system is among the safest in the world. The fatality rate on Illinois highways has declined by almost two-thirds since 1982 despite a steady growth in travel during that period. With the projected increase in the demand for transportation in the future, keeping the Illinois transportation system and citizens safe will continue to be a top priority for IDOT.

Our work on roads, traffic safety initiatives, programs, and laws are designed to encourage safety behaviors and promote safe driving in Illinois.


  • The Sustained Traffic Enforcement Program (STEP) helps Illinois maximize the effect of sustained, stepped-up, year-long traffic enforcement. By providing hire-back funding for local police officers, STEP brings impaired driving and seat belt enforcement closer together because of the connection between late-night alcohol-involved fatalities, late-night unbuckled fatalities and lower late-night seat belt usage rates. STEP-funded enforcement details focus sharply on specific times of the year and specific times of the day when data shows alcohol-involved and unbuckled fatalities are highest. Paired with strong Click It or Ticket and Driver Sober or Get Pulled Over messages during each enforcement period, the combined impaired driving and seat belt enforcement is the cornerstone of Illinois’ battle to reduce serious injuries and fatalities on its roads.
