A car overturned on the A505 roundabout in Stopsley during rush hour last night (July 31).
Two vehicles were involved in the incident on Putteridge Road and emergency services were called to the scene at about 5.45pm.
The drivers had slight injuries but no one was trapped in the vehicles and no one was arrested at the scene.
An onlooker said the fireman were trying to turn the blue Vauxhall Corsa back over by tying a cable to a streetlight.
Traffic was extremely congested while the incident was dealt with.
Police remained at the scene until 8.25pm after questioning the drivers.
