Clay on the road

During wet seasons, it is common for roads to become contaminated with clay. Farmers and contractors drive tractors and trailers on the roads with tires covered in clay. This clay is brought in from the fields where crops have been harvested. This is dangerous because clay on the road causes slippery conditions. We check the roads extra carefully for contamination during these periods.

Polluter liable

Littering on the road is prohibited by law. If it does happen, the litterer is liable. They must clean up the road. Otherwise, we will do it at the litterer's expense.

During months with high precipitation, there is a greater chance that the road will become dirty. Rain makes the fields more soggy and causes clay to stick to the wheels. It also has to do with the fact that crops grown on clay are harvested in the wet autumn. That is why we check our roads extra carefully for dirt during that period. 

Warning signs

Farmers and contractors may place warning signs when carrying out work. These signs alert road users to the dangerous situation. These include a warning sign for slippery conditions, a sub-sign with the text 'clay' and a recommended speed sign of 30 km/h. The signs may only be removed once the work has been completed and the road has been cleaned. Placing signs does not exempt the polluter from their obligation to keep the road clean or to clean it.

Information about where these signs can be obtained and what requirements they must meet can be found in the instructions below. It also includes tips and explanations about placing the signs on clay roads. If you have any questions or complaints about dirty roads, please contact us at 072 - 582 8282 or info@hhnk.nl, stating 'clay on the road' and the location (such as street name and house number).
