The State Government has promised legislation to ensure motorists keep at least one metre away from cyclists, if it is re-elected.

Infrastructure Minister David O'Byrne said a Labor government would conduct a trial mandating a minimum passing distance of one metre by drivers while overtaking riders, similar to a trial conducted in Queensland.

Mr O'Byrne said last year four cyclists were killed on Tasmanian roads and the measures were needed to protect the state's growing number of cyclists.

He also announced a new Cycling Safety steering committee to be formed by the Road Safety Advisory Council and said it was important that RACT and Tasmania Police were involved, with ideas for ensuring that the 1m law was enforceable.

Mr O'Byrne also announced a partnership with the Amy Gillett Foundation.

"As a priority we will also develop a Tasmaniaspecific education and awareness campaign with the Amy Gillett Foundation,'' he said.
