Good morning, A vehicle fire is causing major problems on the road network this morning - and it is only expected to get worse.

As a result, traffic is at a standstill from Hatfield on the A1 and it is affecting the M25/A1 roundabout. Queues in both directions to get off at j23 on the M25. Local traffic via Chipping Barnet also affected.

Elsewhere slow on the M25 anticlockwise approaching the M40 from j18 for Chorleywood.

Busy on the M11 southbound between the M25 and A406.

Slow on the A405 between the Noke hotel in Chiswell Green and the M1 at Bricket Wood.
