This is the shocking moment two motorists trade blows as they waited in traffic on a busy motorway.
Footage shows how the two middle-aged men get out of their stationary cars and throw punches as stunned commuters look on.
The incident occurred on the London-bound section of the M25 on June 15 - a sweltering summer's day which saw the mercury reach 25C.
The road rage incident began after the man in the pink shirt allegedly cut off the other driver, according to the person who filmed the video.
