Officers were called to the scene earlier today and discovered the car mounted on top of the barriers.
The car was travelling towards the M27 when it attempted to cross into another lane, heading to the M271.

In an online post, officers said: “If you’re in the wrong lane, do not just move over at the last minute.
“Carry on to the next available safe location to turn around and continue with your journey.
“Accidents like this in Southampton can be avoided.”
The post went on to say that a ‘keen driver’ decided to almost bring traffic to a stop to photograph the crash scene.
They added: “She failed to see the police officer stood in front of her whilst taking a picture, and our marked police car.”
