The article is generally reliable and trustworthy as it provides accurate information about the current weather conditions in the Netherlands. The article also provides useful advice from Rijkswaterstaat and ANWB on how to drive safely in these conditions. However, there are some potential biases that should be noted. For example, the article does not provide any counterarguments or alternative perspectives on the situation; it only presents one side of the story. Additionally, there is no mention of any potential risks associated with driving in such conditions or any other safety measures that could be taken by drivers. Furthermore, there is no evidence provided for some of the claims made in the article such as "enkele ongelukken" (several accidents). Finally, there is a lack of exploration into other factors that may have contributed to the current weather conditions such as climate change or human activity.
