A village resident claims the council must sort out a notoriously slippery Harefield road where there have been a dozen accidents in the past year and two more last week.
At around 8am Malcolm Brown, of Newdigate Road East, was horrified to find a car had overturned on 'sheet ice' in Breakspear Road North.
Mr Brown said: "A van driver stopped, then a nurse from Harefield Hospital. I held the door open while they got the woman driver out, and in five minutes the ambulance arrived. We then pushed the car back over.
"The ice is from water that comes off a farm, where the drain is blocked.
"The council needs to sort out all the potholes too."
Another driver was taken to hospital after an incident at the junction of Gilbert Road which involved two cars.
Mary Worrall, Head of Highways and Green Spaces, said local knowledge is vital to Hillingdon Council, which had not had recent reports of problems on Breakspear Road North.
"The council maintained a vigilant watch on weather conditions and responded by gritting major routes and blackspots," she said. "Following the bad weather there were unusually high quantities of water on some semi-rural roads.
"Drivers are always advised to take extra care during exceptional road conditions."
