The Easter getaway is set to begin with millions of people setting off for UK breaks and holidays overseas - and the RAC is warning drivers to prepare themselves for a "bad" Good Friday on the region's roads.
The roads will be busiest on Thursday, according to an AA poll of more than 24,000 drivers - and the West Country is set to see one of the busiest stretches.
One portion of the M5 made it into the AA's top three most likely to be congested list.
- M5 south from Almondsbury, Gloucestershire towards Exeter
The RAC has also published a list of likely traffic hotspots - naming all major routes to and through Devon and Cornwall and many other parts of the West.
- the M5 between Bristol and Taunton is likely to experience particularly heavy traffic
- the A30 into Cornwall is likely to be congested
- the A38 into Cornwall is likely to be congested
The RAC claimed it was "inevitable" that popular road arteries will be congested and warned drivers to expect "heavy traffic and jams on major routes".
People are advised to plan their journeys and make an early start to try and avoid the worst of the anticipated heavy traffic conditions.
