As well as warning motorists to take care, police officers have also warned farmers of their legal obligations to help keep roads safe.
It comes as officers warned of a seasonal increase in the number of accidents reported during the harvest.
Ch Insp Steve Owen, from Warwickshire and West Mercia Police's joint operations department, said legal action would be taken against anyone found to be breaking the rules.**
Farming vehicles should pull into lay-bys to let traffic pass during busy times, he said, and need to make sure their vehicles are clear of mud before hitting a public road.
Officers have also warned motorists to take extra care and avoid dangerous manoeuvres.
Slow-moving tractors and extra mud on road surfaces during harvest season means motorists need to take extra care on the region's rural roads, police have warned.
As farmers across the region prepare to harvest their crops, the Safer Roads Partnership run by Warwickshire and West Mercia Police revealed the increase in farming activity at this time of year traditionally leads to a surge in the number of accidents.
They say drivers often take unnecessary risks such as overtaking at inappropriate points or speeding, not leaving themselves enough time to stop if they unexpectedly come across a slow-moving tractor.
The amount of mud and other debris on the roads also increases, making the surface slippery and more difficult to stop on.
