The first ever Europe-wide crackdown on speeding is taking place today.
The 24-hour marathon effort will involve speed checkpoints across 22 countries until 6pm tomorrow morning.
It is being coordinated by the European Traffic Police Network, TISPOL.
In the German state of North Rhine-Westphalia, where the concept was conceived, members of the public have once again been invited to vote on the locations where they would like speed enforcement measures to take place.
TISPOL president, Aidan Reid, said: "The speed marathon is all about prevention. We want drivers to think about the speeds they choose; speeds which are both legal and appropriate for the conditions. By doing so, they will be reducing the risks they face and the risks they pose to other road users."
"We encourage members of the public to join our road safety conversation and show their support for this life-saving work on Twitter, using the #TISPOLOpSpeed hashtag."
Illegal and/or inappropriate speed is the single biggest factor fatal road collisions. Last year, 27,500 people died in road collisions throughout the European Union.
In Ireland, 196 people lost their lives on our roads last year. To date in 2015, 47 people have died.
Chief Superintendent Reid says although that is five fewer than this date last year, "it is still 47 too many."
Over the next 24 hours:
- In Germany, 13,000 officers will be involved at 7,000 speed checkpoints, most requested by members of the public
- Estonia, Latvia, Lithuania and Finland will conduct joint speed checks and border security controls along the Via Baltica
- In Serbia, 1,000 officers will be involved in speed controls during the marathon
- A total of 90 speed checkpoints in Cyprus have been chosen for the marathon
