Two children were among those injured in a four car crash on the A329.
Half the cars caught fire and other drivers stopped to rescue passengers.
A Ford, Nissan, Polestar and Volkswagen collided on the slip road at Coppid Beech roundabout at around 1.20pm on Saturday (January 22).
The children, aged seven and ten, a woman in her forties, a woman in her twenties and a man and a woman in their seventies suffered minor injuries.
All were either checked at the scene or taken to Royal Berkshire Hospital as a precaution and released later that day.
“I want to reach out to the public for any possible dash-cam footage people may have of this collision but to also thank those that stopped to assist before the emergency services arrived,” said PC Martin Danks, of the Joint Roads Policing Unit, based in Reading.

“The collision caused two of the vehicles to catch fire and I understand a good number of people stopped and assisted in getting those involved, some of whom were injured, out of the burning vehicles.
“Unfortunately, many who had done the good deed left before leaving their details, likely because they did not see the collision itself and thought their bit was done.
“I would like to praise those that took the time to stop and help but please get in touch with us if you haven’t already.
“Anyone with information should call 101 or make a report online, quoting reference number 43220031808.”
