Agencies may designate and use 10-40 and above to suit their own needs. 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. TABLE of FREQUENCIES FEDERAL BUREAU OF INVESTIGATION 163.8375/167.600 167.2375 167.4875 167.5625 DRUG ENFORCEMENT AGENCY 418.625/416.050 418.900/416.325 418.750 418.675 418.825/415.600 418.950/416.200 418.975/417.025 418.975
