Drivers taking part in a Pro-Brexit protest along the A30 were pulled over by police this afternoon.
The Cornwall Go Slow protest was one of dozens of events due to be held across the country by pro-Brexit groups. In Devon, lorries are expected to block the M5 this evening.
Approximately 10 vehicles took part in the protest, which resulted in miles of queueing traffic but the rolling road block was halted near Bodmin after officers directed the Brexiteers into a lay-by.
The protesters had been warned by police not to take up two lanes or to travel too slow.
Officers say two drivers ignored the warning and have been reported for inconsiderate driving.
In a series of tweets Inspector Si Jenkinson, of the Alliance Roads Policing Team, said: "We stopped 9 vehicles, the front two have been reported for inconsiderate driving the remainder given words of advice and allowed to continue their way and an appropriate speed. If they repeat their actions they are aware we have their details and prosecutions will follow.
"We recognise the right to protest and make views clear but we will not tolerate careless and inconsiderate driving on our roads. We engaged with organisers before the go slow began, they ignored our advice to stay in lane 1 and limit speed to no less than 45mph."
He added: "Deliberately slowing or stopping traffic amounts to inconsiderate driving. The drivers were stopped and have been reported for that offence.
"The rest have been advised they face the same should they continue."
The vehicles, three of which have been decorated in banners and flags, left the service station at Plusha at about 3.30pm.
Traffic monitoring services reported that the protest had resulted in seven miles of traffic.
Initially organisers said 25 people had signed up to take part in the rolling road block after the prime minister asked the European Union to delay the UK’s exit date beyond March 29.
Approximately 10 vehicles took part.
Speaking at the start of the protest, organiser Ian Grindod said: “It was never going to be a massive event anyway.”
