Dublin Traffic Light Proliferation Causes Frustration for Drivers and Cyclists
Barry Walsh attributes drivers running red lights in Dublin to the frustration caused by a 66% increase in traffic lights on key routes, often for cycle lanes. Cyclist Tom Molloy explains his reasons for running reds, including lights not detecting bikes and avoiding dangerous traffic. Both highlight the need to acknowledge the distinct challenges faced by drivers and cyclists in urban environments.
Clare Moriarty criticized motorists for running red lights, a behavior Barry Walsh attributes to the proliferation of traffic lights in urban areas, often for cyclists. He cites a one-mile stretch between Marino Crescent and the Five Lamps in Dublin, which now has 10 sets of traffic lights. Four new sets were installed in 2025 during a two-year cycle lane construction, increasing lights by 66% on this busy route.
Walsh notes that none of the new lights relate to the cycle lane; one is for pedestrians despite a nearby footbridge. He suggests Dublin's traffic management aims to deter driving, leading to driver frustration and dangerous liberties at lights. Tom Molloy, a cyclist, explains why he sometimes runs red lights: some lights only change for cars, requiring indefinite waits for cyclists. He also does it to avoid dangerous merging traffic and for convenience when turning left with no traffic, citing physical exertion.
Molloy points out that in many countries, cyclists can legally break lights when turning at their own risk. He argues that drivers and cyclists are different, with cars being more dangerous. He also notes that pedestrians often break laws by not using designated crossings or waiting for the green man, taking calculated risks. Molloy urges drivers to accept these differences.
