234. Salt
Salt is commonly used for deicing and anti-icing roads in winter. It lowers the freezing point of water, helping to prevent ice from forming or to melt existing snow and ice. Road authorities may spread dry salt, wet salt or brine before or during freezing conditions. Salt improves road safety, but drivers should still reduce speed and adapt to slippery conditions because treated roads can remain hazardous, especially during heavy snowfall, freezing rain or very low temperatures.
Is salt used to treat roads in Belgium?
Yes. Belgian road authorities use salt, wet salt and brine to help prevent or remove snow and ice during winter conditions.
Are Belgian roads salted before ice forms?
Yes. Road authorities can carry out preventive salting before frost, ice, snow or freezing rain develops. This is known as anti-icing and can reduce the risk of slippery roads.
Who is responsible for salting roads in Belgium?
Responsibility depends on the road. Regional authorities maintain motorways and regional roads, while municipalities are generally responsible for local roads under their control.
Does salting mean a Belgian road is no longer slippery?
No. Even after treatment, roads can remain slippery during snowfall, freezing rain, frost or rapidly changing temperatures. Drivers must still adapt their speed and following distance to the actual conditions.
Does Belgium use preventive salting?
Yes. In Flanders and Wallonia, winter services use preventive treatments based on weather forecasts and road-condition monitoring to reduce the risk of frost and ice forming.
When does the winter road service operate in Belgium?
The exact organisation differs by region. In Flanders, the winter service normally runs from the third Monday of October until the fourth Monday of April. In Wallonia, the regional winter service normally runs from 15 October to 15 April.
