After narrowly cycling past a car in the middle lane, the cyclist crashes straight into the motorcycle on the left-hand lane.
The motorcyclist seems to have tried avoiding the cyclist, but to no avail.
The cyclist is subsequently knocked off the bicycle, and falls to the road.

Rules for cyclists on roads
According to the Road Traffic (Bicycles) Rules, cyclists must, as far as possible, keep to the "far left edge of the road" unless overtaking.
The exception to this rule is if the cyclists are turning right at the next junction.
In addition, cyclists should also ride in a manner so as not to obstruct vehicles moving at a faster speed.
Should cyclists be turning or changing lanes, they are also required to signal their intentions.
