Motorists in the Shepton Mallet area are being urged to take care as the autumnal weather takes effect on the roads.
Emergency services have been called to a number of vehicle accidents over the last week across the district.
In one crash, during the morning rush hour, a car crashed off the A361 between West Pennard and Pilton, overturning into a ditch.
The cause of the crash on September 28, and the other accidents, are not known.
However they come as road safety charity the Institute of Advanced Motorists (IAM) issued stark warnings about the dangers of driving in the autumn.
Peter Rodger is IAM's chief examiner and urged drivers to take extra care, particularly driving in the mornings.
"Remember that leaves can be slippery, especially when wet so avoid hard acceleration or braking as it can cause skidding," he said.
"Be aware that there may be a dip, pothole or other road hazard hiding under the leaves covering the road, and hold the wheel firmly if you must drive over them."
