Motorists driving home for Christmas have been urged to take care after a series of crashes on a major Oxfordshire route. 

Thames Valley Police said it has been called to five separate crashes on the M40 in the heavy rain this morning (Friday). 

All five of these collisions were as a result of motorists "spinning out of their lane" due to the slippery road conditions.

Drivers have been asked to remember to keep their lights on and to avoid tailgating. 

A statement from Thames Valley Police said: "Please take extra care on the roads this morning with heavy rain causing lots of surface water hazards.

"We’ve attended five collisions on the M40 already where motorists have spun out." 

Heavy rain has been falling in the county this morning (Friday). 

It comes after the Environment Agency issued a flood alert for Oxfordshire earlier this week.

This was due to rising water levels in the county following high levels of rain. 

People have been urged to avoid using low lying footpaths or entering areas prone to flooding.
