The final major getaway of summer will start from Friday 26 August as families take advantage of the last chance for a road trip, the AA says.

Amber Traffic Warning for 15 million bank holiday trips – AA

Sunday and bank holiday Monday afternoons and evenings are expected to be particularly busy as travellers return from vacations and the ‘last hurrah’ trips of the summer season.

The AA estimates that 45% of drivers will embark on a car journey during the long weekend, either on holiday or days out – which equates to nearly 15 million leisure trips.

The AA Route Planner has issued an Amber Traffic Warning lasting from Friday 26 August until Monday 29 August, as holidaymakers and festivalgoers meet on the roads over the last weekend before all UK schools return.

The AA expects Saturday 27 August traffic to reach its peak between 10am until 4pm, followed by the next busiest travel days of Friday and Monday.

Predicted AA Route Planner traffic hotspots:
• M4/M5 interchange near Bristol
• M25 Western and South Western sections
• M5 between Taunton and Exeter
• M1 between the M25 and Newport Pagnell
• M6/M42 Birmingham
• M62 Liverpool to Manchester section and Leeds
• M60
• M56
• Edinburgh area (M8, A90, A720)

Drivers are advised to expect delays on major routes and plan ahead.

Holiday travellers will be helped by the average price of petrol falling to 171.41p a litre on Sunday. At the beginning of July, it had hit a record of 191.53p a litre. The more than 20p a litre saving cuts £11.06 from the cost of filling the typical car tank. Diesel continues to fall and, at 182.70p a litre on Sunday, now averages 16.37p cheaper than its 199.07p a litre record at the start of July.

Sean Sidley, AA Patrol of the Year, said: “This year we are predicting up to 15 million journeys will be made over the August bank holiday, as families make the most of the warm weather and have a last hurrah before the new school year.

“With events and festivals fully back to normal localised congestion will peak at closing time around major venues, but the rest of the UK could see peak journeys throughout Saturday.”
