Motorists faced major delays on the A14 in west Suffolk this morning after a two-vehicle collision.
A blue Peugeot 308 ended up overturned on the side of the dual carriageway eastbound near Needham Market, just before the A140 junction, after a crash involving a silver Jaguar X-Type at 7.40am, police said.
No serious injuries were reported.
Both vehicles were quickly taken off the road but a stretch of the inside lane remained closed as emergency services dealt with the incident.
The incident was cleared at 10.15am.
