The combination of cheap petrol prices and a train strike will see an extra 14 million drivers descend on Britain's roads this bank holiday.
With a First Great Western strike starting on Saturday, the RAC expects there to be an increase of 50 per cent in the amount of people travelling in their cars. With road works stretching along wide areas of the road network, delays are expected to be widespread.
A spokesman for First Great Western told The Telegraph that "positive" talks had been had with the union on Tuesday.
Pete Williams, of the RAC, told The Telegraph: "With the best of the British weather set to make a reappearance, a significant amount of tourists are expected to flock to coastal towns in a bid to soak up what's left of the summer sun."
With oil prices at $43 per barrel, Tesco and Sainsbury's have followed Morrisons by cutting 2p of a litre of unleaded and 1p off a litre of diesel.
Petrol prices are now 24p a litre lower than they were this time last year, with unleaded now costing an average of 113.9p and diesel around 110.8p.
The traffic problem is made worse by festival goers returning from the Reading and Leeds music festivals. This will put even more pressure on an already congested road network.
