Police are warning of “serious disruption throughout the day” as fuel protests are set to target motorways across the UK.
Roads in various areas could be subject to traffic jams on Monday as protesters take action and call for a cut in fuel duty.
Protests will target mainly three-lane motorways and see slow-downs on two lanes, leaving the fast lane free, according to FairFuelUK founder Howard Cox.
While he said his organisation is not involved in the action, he is “fully supportive” of the demonstrations so long as they are conducted legally.
The protests are understood to be organised via social media under the banner Fuel Price Stand Against Tax.
Chancellor Rishi Sunak has said he will carefully consider calls for a “more substantial” fuel duty cut after the 5p per litre reduction implemented in March failed to halt price rises.
Figures from data firm Experian show the average price of a litre of petrol at UK forecourts reached a new high of 191.4p on Thursday, while diesel rose to 199.1p.
The UK Government said while it understands people are struggling with rising prices and have a right to protest, “people’s day-to-day lives should not be disrupted” and warned that traffic delays “will only add to fuel use”.
Organisers are expected to block the Prince of Wales Bridge crossing between England and Wales, while disruption is also possible in Essex and Gloucestershire.
Cox said: “I totally support their protest because people have reached the end of their tethers at the moment.”
He said other countries had cut fuel duty by more than the UK and asked “why the hell are we not doing it here?”
Cox called for a cut of at least 20p, and warned that protests will continue if not.
He said: “There is an appetite (for such protest). If the Government don’t actually deliver on this, I think there’s going to be some serious escalation of protests.”
Gwent Police said protests are expected to take place on the road network between 7am and 7pm on Monday.
They said organisers had indicated an intention to block the Prince of Wales Bridge, with the protest starting on the M4 at Magor services, junction 23A eastbound, and junction 20 of the M4 westbound.
Essex Police Chief Inspector Anna Granger said her officers “are experienced at dealing with incidents which cause significant disruption”.
She said: “We will be monitoring the situation closely and have a policing operation in place to limit disruption.”
Gloucestershire Police said protests are likely to affect the A48, causing travel disruption in the Gloucester and Forest of Dean areas.
