Four people have been charged following a joint operation by Latrobe Highway Patrol and the Sheriff's Department across the Latrobe Valley last Thursday.
Police used an automatic number plate recognition vehicle on Shakespeare Street, Traralgon and Waterloo Road, Moe to identify unregistered vehicles, unlicensed drivers and people with outstanding warrants.
In Traralgon, a 31-year-old Traralgon man was charged with drug driving, driving an unregistered vehicle and driving unlicensed.

The four drivers are expected to be charged on summons and will face Latrobe Valley Magistrates' Court at a later date.
Five infringement notices were also issued for unlicensed driving, four were issued for unregistered vehicles and one for exceeding the speed limit.
Two vehicles were issued with defect notices.
