Easter holidaymakers are being warned of potential travel misery over the extended weekend, with jams and widespread delays expected.
While 1.6 million Britons will head abroad in search of some sun, those staying on home soil face the threat of packed roads, disrupted rail journeys and unsettled weather.
Traffic information company Trafficmaster reckons as many as 16 million cars will be on the move between Friday and Monday, especially given the fact that last Easter proved to be a distinctly chilly one.
Drivers from Northern Ireland are the most likely to get behind the wheel, while Scots appear the least likely to do so.
Inrix, another traffic information company, claims the busiest periods will be all day on Thursday; between 10am and 3pm on Good Friday and between 10am and 4pm on Easter Monday. It's advisable toplan your best journey ahead of setting off.
The M4 between Hampshire and the West Country; the western section of the M25, and the M4 between London and Reading in Berkshire will be some of the most congested stretches of road over the weekend.
To compound the misery, forecasters expect to see isolated showers hit the UK on Good Friday and Easter Saturday.
