Motoring experts are warning drivers to expect delays and congestion this Easter weekend.
The RAC has recommended leaving extra time for journeys as thousands of additional cars take to roads, which are already being made busier by major railway engineering works.
While some will be travelling to and from airports, others will be visiting popular tourist areas such as the Lake District and Cornwall.
RAC spokesman Simon Williams said: "With the hint of better weather ahead people will be heading to the coast and countryside to make the most of the Easter break which will create all kinds of traffic issues. With many schools going back on Tuesday 22nd April we are also expecting a manic bank holiday Monday rush home as people take to the roads en masse.
"We would advise drivers to allow plenty of time for their journeys, particularly from popular areas such as the South West, Lake District and South Wales to avoid getting stuck in the inevitable delays."
A report by Inrix suggests there will be twice as much traffic as non-holiday periods in the worst-affected congestion hotspots in the South East and South West of England.
Gatwick and Heathrow airports will be busy, with a journey around the western section of the M25 taking up to an hour, as opposed to 30 minutes.
Meanwhile there could be delays of up to an hour on the M4 between Hampshire and the West Country.
Other delays are expected on the M1, the M6 and the M4.
