A 26-year-old woman was racially abused and spat on during a road rage incident in Guildford in Surrey.
Surrey Police said the woman was assaulted after she manoeuvred her Mercedes round a Vauxhall Envoy which had stopped on the A320 Woking Road.
A male passenger in the Vauxhall Envoy shouted racial abuse at the 26-year-old before he got out of the vehicle and spat in her face.
Detectives have urged any witnesses to Wednesday's incident to contact them.
The suspect was described as white, in his 40s, about 5ft 7in tall with a pock marked face and ginger hair.
He was wearing a dark coloured jumper and dirty black trousers.
