A campaign to raise awareness of "car-dooring" is needed to save lives on Britain's roads, Cycling UK has said.

The campaign group says cyclists, motorcyclists and pedestrians are being injured and killed by drivers and their passengers carelessly opening doors.

It wants the Dutch reach - which involves opening doors with the "wrong" hand - to be taught to new drivers.

The Department for Transport says it will consider new messages on cycle safety as part of its Think! campaign.

Government figures from 2011-2015 show that eight people died from carelessly-opened car doors.

Three of these had been travelling in cars - five were cyclists knocked off their bikes.

In total 3,108 people were reported hurt but Cycling UK believes the true figure is probably much higher.

It's suggesting an information campaign, warning cyclists to ride further into the carriageway, to avoid the swing of car doors.

It also wants higher fines for careless door opening.

And it's urging ministers to have the "Dutch reach" taught in driving tests.

This manoeuvre involves the driver or passenger on the right-hand side of the car opening the door with the left hand - forcing them to turn and see if anyone's approaching.

It's a mandatory part of Dutch driving tests.

A video of the technique has been seen by more than a million people on the "Outside" magazine website.
