Powers to allow police to search a person or their vehicle for drugs if they return a positive roadside drug test will be introduced to the South Australian parliament.
The opposition will bring the change before the house on Wednesday after failing to have the measure included in a raft of reforms while in government last year.
"This is a simple measure to give police another tool to combat the spread of drugs, particularly ice, in our community," opposition police spokesman Lee Odenwalder said.
"Labor wants to give police all the tools they need to keep our community safe."
The change was previously recommended by the state's ice taskforce and backed by police, Mr Odenwalder said.
