Drivers across the UK are being urged to make important checks on their vehicles and even change planned travel times ahead of the Bank Holiday weekend.

The Queen’s Platinum Jubilee celebrations has led to experts warning drivers they face long delays on popular routes over the weekend as nearly 20 million getaway journeys are planned.

The RAC estimated that 19.5 million leisure trips by road will take place between Wednesday and Sunday.

A survey of 1,460 drivers’ travel plans indicated that Friday is likely to be the most congested day on the roads as day-trippers combine with families returning home from half-term breaks.

RAC traffic spokesman Rod Dennis said: “Drivers clearly see a double bank holiday this close to the summer as a gift with so millions eager to make the most of it – although many appear keen to keep their car journeys short, perhaps mixing a daytrip or two with a Jubilee celebration at home.

“The fact the bank holidays coincide with the end of half-term in many places has the potential to put some extra pressure on the road network, so planning a journey carefully is important to beat the worst of any queues.”

Experts urge drivers to do five things

Traffic information supplier Inrix advised drivers to set off either before 6am or after 3pm to avoid the worst of the traffic.

Meanwhile Rod Dennis urged drivers to carry out essential checks on their vehicles before setting off, such as making sure oil, coolant and screen wash levels are correct, and tyres are properly inflated and free from damage.

“A bit of TLC now could make the difference between a straightforward trip and one beset by a breakdown,” he said.

Network Rail issue update on lines over Platinum Jubilee Bank Holiday weekend

Network Rail normally carries out widespread engineering work during bank holidays, but nearly all major lines will remain open during the Jubilee celebrations.

Chief executive Andrew Haines said: “We are really pleased to say that all routes into London’s major stations will be open across the Queen’s Platinum Jubilee bank holiday weekend.

“We know that demand will be high as people travel into the capital to celebrate this special occasion and our station staff will be on hand to welcome passengers and help them with their journeys.

“Of course, we are still carrying out hundreds of important projects to upgrade the railway, but the majority of these will have no impact on passenger or freight services.

“As ever I’d like to thank the countless railway staff who will be out delivering upgrades or who will be working hard to keep services running for passengers.”
