A cyclist from Nottingham says he feels lucky to be alive after he got his bike wheel stuck in a new tram track and fell over.
Terence Granger, 64, suffered eight cracked ribs and a punctured lung in the accident - and says it could have been avoided with better signage around the roadworks at Southchurch Drive, Clifton.
He told the Nottingham Post: "To my knowledge there aren't any sort of warning signs for cyclists to be careful, and there are no cycle paths around the road works.
"I think more needs to be done. I had my arm out to turn right and the next thing I knew I was literally flung off my bike. The wheel had just got stuck in the track."
Mr Granger added that his helmet was badly cracked in the fall, and that he thinks it probably saved him from further injury.
His wife Jacqui added: "We hope it will make people realise how important it is to wear one."
A spokesman for construction contractor Taylor Woodrow Alstom said: "We are very sorry to hear of Mr Granger's accident and wish him a full and swift recovery.
"We have been working with several local cycling groups to raise awareness of cycle safety in areas where tram tracks have recently been installed.
"This safety campaign has included sending leaflets to homes along the route of the expanding tram network, posters, press articles and an online video.
"We recommend that cyclists crossing tram tracks prepare early, and cross them at a 90 degree angle, and where construction work on the tram expansion is still in progress we have advised them to dismount.
"Many new cycling opportunities are being created as part of the tram extension with new cycle paths, crossings, and cycle stands being installed."
Last year we reported how cyclists in Edinburgh had said a new stretch of tramlines in the city centre are 'lethal' for those on bikes.
A video showing a man having a near miss with traffic when his wheel becomes lodged in the tracks was posted to the internet.
Campaigners said the road's layout could either be addressed, or the grooves in the tracks could be plugged with rubber, as they are in other cities in the Netherlands.
Zurich is also experimenting with rubber plugs at the points where cyclists need to cross the rails.
