Fixed penalties on the cards for cyclists
Dangerous cyclists face fixed penalties under a plan being considered by the Government.
Chief Superintendent Mark Curran said being called to the scene of a cyclist death was "one of the most tragic things you could ever see".
Speaking at Dublin Port for the launch of a new campaign highlighting the danger of 'blind spots' surrounding trucks, Chief Supt Curran warned of a "lax regime" amongst some cyclists.
He backed the fixed charge penalty notice being considered by gardaí, saying "anything that changes behaviour makes a difference".
And he said it was "certainly not a bad idea" that cyclists should learn the rules of the road, adding: "It's not a game, it's a very serious pastime to go out on to the road."
Some 20pc of fatalities of cyclists have been in urban areas so anywhere with congested traffic is a high risk.
The quays in Dublin were "springing to mind" as one of the most dangerous spots in the capital for cyclists, added Chief Supt Curran.
He said the front, back and left sides of trucks posed extra risks. A new campaign to mark Bike Safety Week focuses on the blind spots of trucks - it warns cyclists that if they can't see the driver, the driver cannot see them.
Transport Minister Paschal Donohoe said more than 10,000 cyclists come in and out of Dublin city centre each day and their attitude "makes a huge difference" to safety. In 2014, 12 cyclists were killed, seven more than in 2013.
