The number of people testing positive to illicit drugs while behind the wheel is continuing to increase in Geraldton.
Last Thursday (14/5/15) Police stopped a Holden Commodore travelling along the North West Coastal Highway in Beresford.
The 32 year old man who was driving the vehicle tested positive for illicit drugs.
Police also say they found a set of knuckledusters in the dash compartment of the vehicle.
Inquiries are ongoing in relation to the positive drug swipe test.
The Geraldton man will appear at the Geraldton Magistrates Court at a later date charged with "carry or possess prohibited weapon".
