There's chaos on many Essex roads this morning following heavy rain overnight.
Essex Police has received reports of 37 weather-related incidents across the county since midnight.
Most of the problems have been in central and northern areas of the county.
The A12 southbound was closed near Kelvedon due to flooding on the carriageway. The section of road was closed at about 4am following a crash on which a car went out of control and struck the central reservation.
One lane of the A12's northbound carriageway was also closed but the road re-opened in both directions just before 8.45am.
Other areas where roads have been flooded include: Heybridge, Clacton, Horsley Cross, Colchester, Eight Ash Green, Great Tey and Great Chesterford.
An Essex Police spokesman said: "A large number of roads have been affected by flooding and in some places the water is deep.
"Drivers should take care and drive within the conditions. The rain was heavy overnight and early this morning and there is still a lot of surface water on the roads.
"Reduce your speed in wet conditions and drive with dipped headlights so that they can been seen in surface spray that is being thrown up by other vehicles.
"If drivers are confronted by a large pool of water on the roads they should avoid trying to drive through it and seek an alternative route."
