Luas operator Transdev has released CCTV footage of near misses between trams and cyclists. It's to highlight how close cyclists can come to being seriously injured when breaking red lights.
The videos show a man swerving close to a moving Luas and another man running in front of a tram carrying a bike.
Luas says it does "not want more cyclist injuries", and has described "this type of cyclist behaviour" as "irresponsible."
Dervla Brophy, Communications Manager of Transdev said she wants to "shine a light on the actions of these gambler cyclists."
"We must reduce the number of emergency brakes the trams are forced to make because of reckless cyclist behaviour, we must ensure that cyclists see the footage and understand the trams cannot swerve and take time to stop", she said.
Separately, new figures show the number of cyclists killed in collisions in Ireland rose from 5 to 10 so far this year.
There has, however, been an overall decrease in the number of people killed on our roads.
77 people have lost their lives in crashes - compared with 87 for the same time in 2016.
13 of the road deaths so far this year occurred in Dublin.
