The KNMI weather bureau has issued a code amber warning for black ice on the roads in Brabant and Limburg, and says thick fog in the far south will also cause problems.

A code yellow warning remains in place for the east of the country.

The black ice, formed by moisture hitting frozen roads, will disappear as the morning progresses but motorists should be particularly careful, the KNMI said.

Black ice caused a number of accidents on Thursday evening and one driver was killed on a provincial road in the far east of the country after skidding into two other cars. There were also accidents on the A1 between Hengelo and Apeldoorn and on the A2 in Limburg.

The KNMI says the temperature will remain above freezing for the next few days and the weekend will be overcast with some showers. Night frost will return next week and there could be some sleet later in the week.
