DUTIES OF LAW ENFORCEMENT OFFICERS

A State Trooper, Deputy Sheriff, or Police Officer may be required to perform many duties including directing traffic, assisting stranded motorists, stopping violators for routine and non-routine violations, responding to alarms, chasing suspects on foot, investigating traffic accidents, investigating industrial and home accidents, making felony and misdemeanor arrests, responding to vicious animal calls and complaints, checking buildings for break-ins, interviewing suspects and victims, testifying in court, executing search and arrest warrants, and more.

Most State Police agencies spend more time investigating traffic accidents and enforcing traffic laws, while police departments spend more time investigating non-traffic related criminal activity and other calls for assistance. Police departments do investigate their share of traffic accidents, however. They are usually responsible for accidents occurring within their jurisdiction. State police agencies may take on more traditional police duties also, depending upon their agency, location, etc.
