There is locally dense fog, with visibility that can drop to less than 200 meters. The institute warns that the fog may spread further in the coming hours.
Traffic may be disrupted, and motorists are urged to adjust their driving behavior by reducing speed and keeping sufficient distance.
The ANWB warns motorists with modern cars equipped with light sensors. These systems do not automatically turn on the lights in fog, which can reduce visibility.
The dense mist has not yet caused any major problems on the road. Delays can only occur on the A9, where a rush-hour lane is closed between the Rottepolderplein junction and Velsen due to fog.
