GardaI will enact a National Slow Down day for a 24-hour period starting at 7am to- morrow in an effort to re- duce the number of road accidents.
However, the campaign will take place on the sam e day that garda sergeants and inspectors are due to refuse to log on to the force's Pulse IT system as part of their ongoing industrial dispute.
Already this year, 148 people have been killed on Irish roads compared with 162 for all of 2015.
Gardai said there will be "high-visibility speed enforcement" at 1,031 speed checkpoints nationwide tomorrow.
They will be enforcing speed limits on national primary and secondary roads.
Speed vans, in-car speed detection systems and hand-held speed detection devices will all be deployed.
The operation is being led by Chief Supt Aidan Reid, of the Garda National Traffic Bureau.
"There has been a significant increase in road deaths this year compared with 2015, which was the joint-safest on record," he said.
"Excessive or inappropriate speed is a major contributory factor in road crashes.
"This is not just a catchphrase, this is a stark fact proven by the analysis of four years of fatal collision reports.
"The higher the speed, the greater the risk and the greater the injury if there is a collision."
Among the incidents that gardai dealt with on last year's National Slow Down day was a vehicle being driven at nearly 50kmh over the limit in Co Louth.
