A car fire on the M40 caused traffic misery for commuters this evening.

All lanes on the northbound carriageway, between junction 2 for Beaconsfield and junction 3 for Loudwater, were blocked while emergency services were on the scene. 

Traffic was also held just after junction 2 while the fire brigade put out the blaze. 

Lane four (of four) remains closed, though traffic is now able to pass the scene.

One lane was also closed on the southbound carriageway due to smoke blowing across the motorway, but has recently reopened. 

However, drivers are still facing delays of up to 30 minutes.

More information as we get it.
