Operation C.A.R.E. began in 1977 as a collaborative effort between the MSP and the Indiana State Police, and is one of the nation’s longest-running traffic safety initiatives. It focuses on deterring the three main causes of highway fatalities: aggressive driving, impaired driving and failure to use occupant restraints.
