Motorcyclist knocked off bike as car turns left on Greenford Road near Sudbury Hill

A motorcyclist was knocked off his bike on Greenford Road near Sudbury Hill on Thursday 8 October. A car appears to have turned left across his path into a driveway.

Dashcam footage shared with UB1UB2 appears to show an Audi moving left from the middle lane towards a driveway while the rider came up on its inside. The bike and rider then go down onto the road.

The rider appears to have been able to get back up without serious injury. The driver is seen coming back out of the car to help him lift the motorcycle and move it onto the pavement.

The Metropolitan Police has not said whether the collision was reported to officers. There are no reports that anyone needed hospital treatment.

A busy route

Greenford Road, part of the A4127, is one of the main north to south routes between Greenford and Sudbury Hill. It carries heavy traffic, buses and many motorcycles and delivery riders.

The stretch near Sudbury Hill has a lot of side turnings, driveways and parked cars. Near the junctions with Sudbury Hill and Harrow Road, Greenford Road also has more than one lane for traffic heading the same way. Drivers changing lane or turning off can easily miss a smaller vehicle coming up alongside.

What the Highway Code says

The Highway Code tells drivers to check their mirrors and signal well before turning left. It says they should not overtake just before a left turn, and should look out for traffic coming up on their left, because motorcyclists and cyclists can be hidden from view.

Drivers are also told to move into the correct lane in good time before a turn, not at the last moment. Turning across another lane of traffic means the driver must make sure that lane is clear.

The Code also asks motorcyclists to take care when passing traffic on the left or filtering between lanes. Riders should watch for vehicles that may turn or change lane, and be ready to stop, especially near junctions and driveways.

Road safety groups often say that many collisions involving motorcyclists happen at junctions and turnings, where a driver did not see the rider in time. Motorcyclists make up a small share of traffic in London but a large share of the people killed or seriously injured on its roads.
