BRITS are being warned of traffic chaos this August bank holiday as nearly 18 million drivers prepare for getaway trips. In England and Wales, motorists are set to make 17.6 million leisure journeys between Friday and Monday. The RAC said traffic will start building on Friday with three million trips planned. On top of that, another 6.1 million drivers say they will be on the roads at some point across the long weekend, adding to the strain. Drivers are advised to top up oil and coolant, check tyre tread and pressure, and ensure vehicles are “road ready” before a long trip.
