Roundabouts, pioneered by the UK's Transport Research Laboratory in the 1960s, are designed to improve traffic flow and minimise the risk of collisions between motor vehicles at junctions.
But they can present particular risks to cyclists for a number of reasons including motorists accelerating into the roundabout to make it into a gap, switching lanes suddenly after realising they were in the wrong one, cutting across the rider's line to get to their exit, being distracted by road signs as they try to work out which exit to take, and that old staple, simply not seeing them.
Our latest Near Miss of the Day features two videos from road.cc reader Paul Wharton, who lives in Craigavon, County Armagh. The first, above, shows a driver pulling out onto a roundabout into his path, the second, a driver who takes the wrong lane into a roundabout for the exit he or she is heading for - both occurrences that will be familiar to anyone who cycles on UK roads.
Paul told us: "We have a high number of roundabouts and lots of motorists have no idea how to use them."
The Police Service of Northern Ireland (PSNI) launched its first close pass operation in Belfast in April this year.
Last month, the PSNI said it would be extending the initiative across Northern Ireland, and that as part of its #seethecyclist campaign officers would also be joining in on club rides.
That move followed the death a few days previously of Gavin Moore, who was killed when a driver crashed into him and fellow members of North Down Cycling Club while they were on a ride.
Over the years road.cc has reported on literally hundreds of close passes and near misses involving badly driven vehicles from every corner of the country – so many, in fact, that we’ve decided to turn the phenomenon into a regular feature on the site. One day hopefully we will run out of close passes and near misses to report on, but until that happy day arrives, Near Miss of the Day will keep rolling on.
If you’ve caught on camera a close encounter of the uncomfortable kind with another road user that you’d like to share with the wider cycling community please send it to us at info [at] road.cc or send us a message via the road.cc Facebook page.
If the video is on YouTube, please send us a link, if not we can add any footage you supply to our YouTube channel as an unlisted video (so it won't show up on searches).
Please also let us know whether you contacted the police and if so what their reaction was, as well as the reaction of the vehicle operator if it was a bus, lorry or van with company markings etc.
