Police are being urged to get tougher on farmers who fail to clear mud from roads following two collisions near Ely.
An investigation is underway after there were two car accidents on the A142 at Witchford in a matter of hours.
Emergency services were called to the busy route at around 3.05am on Friday after a BMW left the road and crashed into a ditch.
Firefighters had to cut the roof off the vehicle to release the driver - a man in his 40s - and he was taken to Addenbrooke’s Hospital with minor injuries.
Emergency services were then called to the exact same location just three hours later at around 6.20am.
The collision involved two vehicles and two casualties, although their injuries are not thought to have been serious.
Motorists have described there being a lot of mud on the road at the time and are calling for action.
Trevor Harrington said: “I reported the state of the A142 to police and was told it was being dealt with.
“I had to brake hard to avoid another car which was sliding on the mud. If this was a builder they would be made to sweep the road immediately or face prosecution so why are farmers constantly allowed to get away with leaving roads in such a state?”
Commenting on Ely News online, another motorist said: “We drove home that way on Thursday - the road was so covered in mud that the white lines and cats eyes were obliterated.
“No signs, and no sign of anyone clearing the mud, though agricultural vehicles were working in the fields adjacent.
“The fact is whoever was working in the fields did not follow the correct procedure to warn motorists. This is a stretch of road that you can drive on at 60mph, there was bound to be an accident.”
A police spokeswoman said officers are investigating the cause of the accident but said the only real powers they have is to caution farmers.
A spokeswoman for Cambridgeshire Fire and Rescue Service said: “We would urge drivers to take extra care on the roads at the moment.
“On some of the rural roads in East Cambridgeshire especially there appears to be a lot of mud, making driving conditions sometimes difficult.
“It’s also worth reminding motorists to properly clear their windscreens before they set off on their journeys.”
