Lee Morley, AA expert patrol, told the BBC: “Some people may have changed their plans from travelling overseas and therefore travelling closer to home.”
He added that there had also been a steady rise in the number of journeys each year since the relaxation of Covid restrictions.
This year, 1.9 million more Brits have planned an overnight trip in the UK for Easter weekend than last year, VisitEngland said. However, 5.1 million people told the tourist board that they were undecided, with the top reasons being the weather and finances.
Traffic is set to be at its busiest on Good Friday, according to the RAC, although levels are expected to be consistently high from Thursday, when many schools break up.
Drivers have been advised to set off early in the morning, as congestion is likely to be at its worst from 10:00 BST each day between Thursday and Saturday, and on Easter Monday.
Concerns about rising fuel costs have been raised over recent weeks, with almost a third of drivers increasingly worried about the cost of petrol as the war in the Middle East continues, according to a study by the RAC.
However, this has had little impact of the amount of people taking trips this Easter.
Sean Kimberlin, RAC mobile servicing and repairs team leader, said: “While a significant number of drivers are concerned about rising fuel prices, a much smaller contingent are actually changing their plans this Easter as a result.”
Prime Minister Sir Keir Starmer has addressed concerns of petrol rationing, telling motorists that there was “no need to do anything other than what is normal”. He added that petrol stations are “well-stocked nationally and any suggestion otherwise is incorrect”.
