Road rage reared its ugly head in Kampong Speu on Saturday when one Lexus driver’s rear window was smashed by an angry motorist.

The Lexus owner tapped on the horn when he saw a Ford Ranger barrelling towards him on the wrong side of the road.

Enraged, the Ranger whipped around, speeding after the Lexus and shattering a window with a hunk of metal.

Cops are using footage from a camera installed on the car to investigate.
