Companies responsible for traffic management during roadworks on state roads will now face fines if they leave speed limit signs on the road when they are not required - to help avoid unnecessary traffic disruptions.
"This has been a particular bug bear of mine, having to slow down for roadworks when there is no work going on and no workers in sight," Mr Ellis said.
"Under new regulations which start on April 5, fines of up to $1250 will be available if incorrect speed limit signage is in place when work isn't taking place and there is no requirement from a safety perspective.
"I hope it means there will be less unnecessary disruptions for road users from now on", Mr Ellis said.
"I look forward to seeing how the regulations work in practice to determine if any further changes are required."
The Government has written to stakeholders that are major road traffic management companies who are pre-approved to undertake traffic management on DIT roads to inform them of the changes.
