PUBLIC hearings about the challenges of newly introduced alcohol interlock devices will resume in parliament in a couple of weeks.
The devices became mandatory on July 31 for Tasmanian drivers who record high blood-alcohol levels or who are repeat offenders.
Drivers are unable to start their car if the device detects alcohol in their breath.
The retrospective nature of the law and the high cost of the devices has been criticised.
Yesterday the Parliamentary Standing Committee on Subordinate Legislation heard from a lawyer, a driver and representatives from the Department of Infrastructure, Energy and Resources.
Committee chairwoman Ruth Forrest MLC said there was "broad agreement" that alcohol interlocks were an appropriate measure.
"It helps people to separate drinking from driving," she said.
"It allows people to drive, but not to drink while they do drive.
"It's part of an educative process."
Ms Forrest said drink- drivers put themselves and other road users at risk.
"The department did provide figures about the number of fatalities and serious injuries in relation to alcohol," she said.
"You can't deny those statistics, in respect of anyone who has lost a family member on the road.
"This is not appropriate behaviour.
"Whatever we can do to separate those behaviours - it is of benefit to the broader community."
Ms Forrest said the department recognised some of the challenges with the regulations and possible changes to the area of exemptions were being considered.
She said further discussions would be held.
