Dramatic dashcam footage shows two angry drivers racing to overtake each other on a busy school road.
A grey Range Rover and white transit van can be seen swerving to get ahead despite being in a long line of traffic, narrowly avoiding other vehicles.
The road rage clip was captured by a motorist in Boston, Lincolnshire, and was uploaded to social media yesterday.
The van driver speeds up along a 40mph stretch - pursued by the Range Rover - as they career past another car.
One man warns: 'It's gonna end in tears, I'm telling you.'
But as the Range Rover tries to overtake him for a final time, the van driver quickly turns left down a side road.
The video was later uploaded to Facebook where it has been viewed more than 5,000 times and has caused outrage.
