Launceston's Southern Outlet's speed limit could be reduced by 20km/h under a new proposal from the Department of State Growth.
State Growth is seeking feedback from users who travel the Southern Outlet on the Midland Highway.
The proposed reduction would affect both lanes for about two kilometres, from the Bass Highway interchange to the Pipeworks Road intersection.
"This section of the Southern Outlet carries about 28,000 vehicles a day and has a high rate of crashes per kilometre and crashes per vehicle-kilometre travelled," State Growth said.
"Since 2013 there have been 137 reported crashes on this section on the Midland Highway."
The department said research showed that even a small reduction of 10km/h of travelling speeds can lead to a 25 per cent reduction in serious casualties.
Comments on the proposal opened on Wednesday, with comments about the proposal already getting mixed reviews.
"Travel this road at least six days a week, three of those at peak morning and afternoon times. Lowering the speed limit is a good idea. Way too difficult to enter the outlet from the Bass Highway at 110[km/h] given the need to slow down in the slip lane," one comment said.
"Too many impatient drivers sitting less than one car length behind each other heading North at 110km/h is dangerous. Have witnessed many near misses and fed up with aggressive tailgating. Heading south [is] not much better."
However, others have said there is no need for a reduction.
"I travel this road every day and cannot see any reason to reduce the speed limit. Maybe the police should start booking all the [people] who think the right lane is the slow lane," another said.
Royal Automobile Club of Tasmania's membership and community executive general manager Stacey Pennicott noted the proposal and will refer it to its Northern advisory council for consideration and comment.
The proposal will be open for comment until May 29.
