A driver who swerved to avoid a pothole, causing another car to crash into a tree, is being sought by police.
A bronze-coloured Ford Fiesta left the road and hit the tree in Chappel Road, near Bures at about 5.55pm on Saturday.
The driver was badly shaken but was uninjured.
Pc Allan Discombe, of Essex Police, said: “We are looking for any witnesses who may have seen a dark-coloured car, possibly a Vauxhall Corsa, which swerved to avoid a pothole causing the Fiesta to swerve and crash.
“We would also ask the Corsa driver to come forward so that details can be obtained.”
Anyone with information should call Pc Discombe on 101.
