According to the AA, traffic is slow on the M25 clockwise between J9 A243 (Leatherhead) and J12 M3. An earlier accident on the motorway between Cobham Services and J10 A3 (Wisley Interchange) led to queues.
The cars were stopped on the clockwise carriageway, but all lanes have since been reopened.
Drivers are facing further delays on the M25 clockwise between J13 A30 (Staines) and J15 M4.
Meanwhile, motorists are stuck in traffic jams on the M25 anti-clockwise at J23 A1(M) (South Mimms) due to an overturned car.
All lanes have now been reopened following the incident.
