Moment police van BLOCKS queue-jumping driver who tries to sneak off a slip road

A police van was caught on camera toying with an apparent queue jumper by repeatedly nudging forward to stop them making a last-minute cut in on a slip road.
However, it later emerged the vehicle was carrying emergency medicine.
The footage, filmed by lorry driver Alan Crosby, shows a Metropolitan Police vehicle standing up to a blue van as tries to barge into a slip road in Bow, East London, moments before the road split.
The 51-year-old said the video shows cringe-worthy scenes between the police van and the Courier Network Systems vehicle.
Officers appear to dish out a few words of advice to the hopeful queue jumper, before forcing them to miss the junction and continue on in the lane they were originally in.
However Courier Network Systems hit back at the tactics and said that the vehicle was carrying patient medication that had a limited lifespan.
A Met spokesman said that the officers would not have been aware that the vehicle was transporting medication.
A spokesman for Courier Network Solutions said: 'Our vehicle was carrying patient medication, which is only effective for a short time, after which it is deemed useless.
'It was, therefore, imperative that the material be delivered to its intended destination in the shortest possible time.
'Our driver was completing his duties to the best of his ability and certainly was not committing any traffic offences. He explained to the police officer that he was transporting urgently-needed medication.
'The manoeuvre caused our vehicle to lose valuable time as it was diverted.'
A Met spokesman said: 'Of course the officers would have been completely unaware of what was being transported by this courier company.
'There are recognised couriers, who for example transport blood urgently around London, that police are well aware of and interact with.
'Any driver carrying out a risky manoeuvre should expect the police to pay attention to their driving as risky manoeuvres are one of the five identified top risk factors that are present in over 70 per cent of all serious or fatal collisions in London.'
