According to the data from RAC Traffic Watch, Saturday October 22 will see some 4.4 million leisure journeys being made on motorways and A-roads, meaning this will be the busiest day.
But these roads look set to be busy throughout the half-term break, with around 4.1 million trips expected to be made on both October 21 and 24.
From October 21 to the end of the half-term, some 31 million leisure trips will be taken in total, as motorists rush to take advantage of the last break before Christmas, according to the RAC.
“We’ve had a long period of pretty settled weather recently and while things might be set to cool down a little into next week, there is still likely to be a lot of dry weather about – meaning this half-term will be a great time for families to pack up the car and get away for a day or more,” said the RAC’s Traffic Watch spokesman Rod Dennis.
The motoring organisation is also advising drivers to make a few simple checks of their vehicle before they head off on a longer journey.
These include looking at things like oil, coolant and washer fluid, as well as tyre and tread pressure.
Figures show that last year nearly 600 road accidents were caused by motorists driving on illegal, defective or underinflated tyres.
Drivers are also being cautioned to be wary of glare from the sun and to be sure to travel with suitable eyewear within easy reach.
Every year there are between 2,500 and 3,000 accidents on UK roads caused by the dazzling sun, the RAC said.
