Police are trying to trace a driver who reportedly failed to stop following a crash on the M20.

The collision happened on the London-bound carriageway near Aylesford, at 7.45pm on Monday.

A motorist reported that she was driving her silver Toyota Yaris in the outside lane when a large black vehicle came up behind her flashing its headlights.

She then attempted to move over but lost control and crashed into the central barrier.

The lane was closed while the vehicle was recovered but the woman was not seriously injured.

It is believed the vehicle that failed to stop was driven by a white man with a child in the front passenger seat.

Anyone who saw the collision or a black vehicle driving erratically around the time should call PC Simon Masterson on 01622 798538 quoting reference 25-1284.
