A school bus driver blasted his horn for over 40 seconds as the author was cycling home from visiting her brothers grave. She warned that if everybody cycling just disappeared it would mean more congestion and more frustration. A school bus driver was apparently so incensed that he could not overtake Joan Donnelly, while she was cycling home after visiting her brothers grave, that he blasted his horn for over 40 seconds.The Rules of the Road states that motorists should Only use a horn to: warn other road users of on-coming danger; or make them aware of your presence for safety reasons when reasonably necessary. This does not include demanding a cyclist to get out of your way, but it is a guideline rather than a law.Under the current legislation, it is an offence to use a vehicles horn in a built-up area between 11pm and 7amunless there is a traffic emergency.The author and former weather presenter said that the bus driver had started to overtake while there was a solid white line on the road, and an oncoming car approached. She waved at the driver to warn him to stay back in case he couldnt see the car approaching.On X and then on Newstalk late last week, she said the drivers response was to hold down his horn for the better part of a minute. At first, when she heard the horn, she thought something might have happened between the car and the bus driver, but then she realised that the horn-blowing was aimed at her.Donnelly says the bus driver was dropping off children when she exited a cycle path about 500 metres from her home in Dublin, and she entered the roadway to cycle the last bit to her housing estate. Shortly after that, the driver tried to overtake but failed because there was an oncoming car.The bus driver who had children still on board then held down his horn, apparently just in anger that he was unable to overtake. When Donnelly made the turn towards her housing estate, she said that the bus driver then screamed abuse at her.Donnelly said: I know exactly when it happened because I was visiting my, brothers grave for his anniversary. So it was the 25th of May, right in the middle of that spell of very hot weather we had there.She said that she had cycled the 44km to the graveyard and back without issue, and it was a lovely sunny day, until she met the aggressive bus driver.I had no incidents, I had a lovely time, I was singing to myself in my head, and I was coming off the cycle path very close to my home about 500 metres from home, and I saw the bus was um unloading passengers. I noted it, but it was stopped a good distance away from the end of the cycle path, she said.Donnelly continued: I proceeded cycling [into the carragway], we went through a set of traffic lights and just after we went through the start of traffic lights, I became aware of the noise of the engine behind.It was getting quite loud and quite close, and at the same time, I saw an uncommon car from the other side. So I was like oh hes got to try and overtake, she said. She said she put my hand up to signal the bus driver behind her not to overtake. She said there was a bend in the road too, so he couldnt have safely overtaken.When the driver started beeping, she thought that the car didnt get in on time, or you know, something has happened behind her because otherwise why would he have sounded the horn? But Donnelly said: I looked over my shoulder and no, he was just annoyed that he hadnt managed to overtake. And there wasnt another opportunity for him to overtake because we are now on a bending, narrow road.She said she kept blowing the horn, which was quite startling she said that she took out her phone because she thought that hed see it and back off, but he didnt.The well-known former weather presenter said: I edited out the video because I didnt want to show the driver, but they sounded the horn for more than 40 seconds. And then, because I was at my house in the stage, so I was pulled into the filter [turning] lane to pull into my [housing] estate, and I pulled in to filter, and he stopped because he had to unload his passengers again, and he started shouting at me again.Asked what he said, she said: He was just annoyed. He was just annoyed and screaming at me. Donnelly said that maybe he got a fright with the failed overtake, But then that fear led to anger, it led him to the dark side. He just unleashed this awful anger.She said that maybe a year ago she would have put up the unedited video, but thats not the point, the point was the unnerving misuse of the horn, which was played a number of times before as well as during the item on Newstalk, which was broadcast on Friday.You dont sound a horn at someone because youre annoyed at them. Thats not the proper use, Donnelly said. Newstalk presenter Andrea Gilligan said: You certainly dont for 40 seconds continuously.Donnelly said: Absolutely not. Thats road rage. sounding the horn at a cyclist just because they are cycling on the road is not appropriate use of the horn, it should be illegal.I always say the horn should be as loud inside the car as it is outside the car, and then people might use this more judiciously. Its supposed to be alerting people to danger If the danger is that youre going to run over them, thats also not appropriate use youre not supposed to be causing the danger, she said.She called on drivers to hold their horses and be a little more patient, and outlined how, most of the time, cyclists do not hold up motorists and people cycling are allowed to be on the roads. She said another incident of a lack of patience was with a Dublin Bus driver on the Malldide Road on Thursday last, when he overtook her just to straight away pull into a bus stop. Going back to the school bus incident, Donnelly said: This bus was taking children to school because the roads are not safe for children to cycle to school.Responding to a listeners text that cyclists think they own the roads, she said: We all own the roads; the roads are there for all of us to use the road at the same time, so we do own the roads.She said that it seems some drivers just want cyclists to disappear, but that would mean more congestion and more frustration as those cyclists would get into their cars more and cause even more gridlock.Responding to other texters, she said that a group of cyclists cycling two abreast is the recommended best practise, especially in larger groups, where it would take longer to pass than if they were single-file.
