The temporary rumble strips will be rolled out over the next few months at selected worksites where the speed limit is 60 kilometres per hour or less.
The bright yellow 20mm high strips will generate a sound along with vibrations when a motorist travels over them.
Minister for Regional Transport and Roads Paul Toole said road safety was a priority of the NSW Government.
“There is an unprecedented amount of roadwork happening across NSW – and the government wants to ensure we are doing everything possible to keep road workers on these sites safe,” Mr Toole said.
“When you approach any worksite, remember to slow down, be patient and help keep everyone on our roads safe.”
Temporary portable rumble strips are currently used in Victoria, Western Australia, South Australia and Queensland.
