More than 30 passengers were taken to hospital after a coach overturned as it left the M40 in Oxfordshire.
Police said it had turned on its side just before 2300 GMT on Saturday, at the top of the northbound exit of junction seven, near Thame.
The driver and 33 passengers were taken to hospital as a precaution. There are not thought to be any serious injures.
Two passengers received treatment at the scene. Police said no other vehicles were involved in the incident.
Those who were taken to hospital were walking around, a spokeswoman for Thames Valley Police said.
