The Queensland Government has released a discussion paper on the proposal.

Royal Automobile Club of Queensland has rejected the option at this time, saying it could backfire on normally law abiding motorists.

The RACT believes the tough measure could land people in court purely because of medication they used.

Infrastructure Minister Graeme Sturges said the current blood alcohol limit (0.05) was in line with best practice international guidelines.

"I recently announced that a re- elected Labor government would spend $430,000 to introduce alcohol interlocks into Tasmania to crack down on repeat drink- drivers and people driving while seriously impaired by alcohol," Mr Sturges said.

"The aim of introducing alcohol interlocks into Tasmania is simple: we want to save lives. The State Government will adopt evidence- based measures to help reduce the road toll."

Opposition Leader Will Hodgman said more could and should be done to make Tasmania's roads safer.

However, his party would review the evidence and data available regarding the blood-alcohol limit, before supporting any reduction.

Greens leader Nick McKim said his party was happy to enter a community discussion on the issue, but at this stage did not have immediate plans to support a lower blood alcohol limit.
