A campaign seeking to improve road worker safety has been launched in Hobart.
The first advertisement in the 'Your Speed is Our Safety' series aired in 2016, with two more to run on television, radio and online in the coming months.
Infrastructure Minister Michael Ferguson said the advertising campaign highlights the impacts of unsafe driving around road works and the serious risks road workers face at their workplaces each day.
"In the past seven years, there have been two road workers killed on Tasmania's roads, and seven road workers have been injured as a result of crashes at work since 2005," Mr Ferguson said.
"The message to the Tasmanian community is this - your speed is our safety.
"We need to trust that when those 40 or 60 signs are out there, it's for a reason."
Mr Ferguson said the advertisements were hard hitting and heart wrenching.
"It's the story of a little girl who was thinking of her dad who was hit and killed because somebody wasn't following the road rules," Mr Ferguson said.
Road Safety Advisory Council chairman Garry Bailey said the campaign drew attention to the wider issue of speed.
"Speed is the biggest killer on our roads," Mr Bailey said.
"Sadly there are too many Tasmanians who are putting time ahead of saving lives."
Mr Bailey said earlier this year 17 drivers were caught driving 20 kilometres an hour over the speed limit at road works areas on the Midlands Highway.
"20 kilometres over is a deliberate act. People need to slow down," Mr Bailey said.
Traffic Management Association of Australia national secretary Camille O'Meara said there are almost daily reports of issues and incidents in the field such as near-misses and people speeding through work sites.
"There is a lack of understanding about why speed limits are put in place around road sites and a sense of frustration," Ms O'Meara said.
"We live in a world where we are all trying to be somewhere as quickly as possible but we need to understand there is a reason behind those speed limits.
"Signs are not just there for the safety of traffic controllers or road workers but also for the safety of the general public."
