This is the moment a driver deliberately blocked a sneaky motorist who tried to beat a traffic jam in the UK with an undertaking manoeuvre.
Traffic had started to build up on the M58 around England's Switch Island on Merseyside, with one motorist filming the gridlock on a dashcam.
But one driver in a silver Mercedes obviously wasn't prepared to wait in the queuing traffic on the outside lane, where vehicles were merging.
He attempted to sail up the inside lane in a sneaky bid to avoid having to wait.
But to his shock, a silver Renault then pulls into the inside lane to block the Mercedes from advancing any further.
