Firefighters have been called to the M40 to deal with a vehicle fire.
Traffic is stationary while firefighters are on the scene between junction 3 for Loudwater and junction 4 for Handy Cross.
It comes just hours after firefighters dealt with another vehicle fire further up the northbound carriageway, between junction 5 for Stokenchurch and 6 for Lewknor.
The rear nearside brakes of a coach caught fire and passengers had to be evacuated at around 9am.
