Firefighters were called to a road traffic collision on Raglan Road in Plumstead.
One car was in collision with a lorry and a parked car. Firefighters released four people who were trapped inside their vehicles. They were treated on scene by London Ambulance Service crews as a precaution.
Station Commander Stephen Irvine, who was at the scene, said: “The car had tried to squeeze through a gap between a parked car and a lorry coming in the opposite direction.
“On arrival crews stabilised the car and the driver and two passengers were able to climb out of the top. They were checked over by London Ambulance Service crews and luckily, were all okay. Crews then made the scene safe by winching the car back on to all four wheels.
“Remember to give larger vehicles, like vans and buses the extra space they need. They will take longer to stop so take extra care.
“It’s also important that you always wear a seat belt, even on short journeys and make sure that children are correctly secured.”
The Brigade was called at 0826 and the incident was over for firefighters by 0845. Two fire engines from East Greenwich Fire Station and a fire rescue unit from Bexley Fire Station attended the scene.
