Police in Cumbria are looking for the driver of a car, which twice rammed another vehicle in what officers have described as a road rage incident.
The incident happened in the village of Dearham, near Maryport, on Tuesday.
Police say a grey Ford Sierra overtook a line of standing traffic near a BP garage on the A594 in the village.
The Sierra pulled in front of a Peugeot car and twice reversed into it. The Sierra then sped off, leaving the Peugeot driver shaken, but unhurt.
The Sierra is said to have sped off towards Broughton.
Police are appealing for witnesses.
