HORSHAM Highway Patrol officers intercepted five drug drivers in the Wimmera on Sunday.
The drivers, all male, ranged in age from 18 to 44.
Senior Constable Cameron Cooper said three of the drivers were intercepted in Horsham – two in Stawell Road and one in McPherson Street.
The remaining drivers were detected in Edenhope and Kaniva.
All tested positive to an illicit substance, and Sen Const Cooper said if the results were confirmed offending drivers would receive a penalty notice for loss of licence or a court summons.
