Speed Limit and signs – Driving rules

The speed limit rules in Belgium are pretty simple to understand. Let’s first start with the default speed limits that apply throughout the country. When you enter the country by road you will see a huge sign, pictured below, stating the default speed limits. I’m going to explain what is shown on the board from top to bottom.

  • Atop the sign is the name of the country, here written in Dutch.
  • Outside of populated urban areas the speed limit is 90km/h. That is about 55mph.
  • Inside of populated urban areas the speed limit is 50km/h. That is about 30mph.
  • On roads with 2 lanes in each direction and divided by a wall of some sort, the speed limit is 120km/h. That is about 75mph.
  • On freeways, indicated by the freeway sign (see below), the speed limit is 120km/h. That is about 75mph.

Below is a list of the current traffic signs that have a speed limit implication.

There are two kinds of speed signs. Zonal signs are valid until they are canceled by another sign. Normal speed signs are valid until just after the next intersection. Every side street where traffic can come out of, is an intersection, not just crossroads.

  1. Zonal signs
    • Enter a populated urban area
      Enter populated urban areaThis is a zonal sign, this means that as long as you are inside the zone indicated by this sign, the speed limit applies. In this case the limit is 50km/h for populated urban areas. When you encounter the same sign with a red (or sometimes black) diagonal line through, then you have exited the zone and the limit no longer applies.
    • Enter an inhabited district with children possibly playing on the street
      WoonerfThis sign is used only on roads in heavily populated districts of the city, where children could be playing in the streets. This is a zonal sign and the speed limit that is implied is 25km/h (about 14mph). The sign is valid as long as you don’t see the same sign with a red diagonal through it.
    • Enter an area with a stated speed limit
      F4AThis is a zonal sign with a speed limit indicated, it is valid as long as you don’t see the same sign with diagonal sign through, in this case the diagonal is black, as it is normally with other non-zonal signs. This sign is mostly used with speed limit 30km/h (about 16mph) around schools. There is also an automated version of this sign that lights up when school children could be present (at scheduled hours). In that case the sign only applies when it is illuminated. When it’s off you can’t read it and thus it does not apply.
    • Enter a freeway
      Freeway signThis sign indicates the start of the freeway. On the freeway the default speed is 120km/h, unless otherwise stated by speed signs. Trucks that carry over 3,5 metric tons of weight are limited to 90km/h speed. The limit is mechanically enforced. On the freeways there are regular speed checks by the police.

  2. Speed Signs
    • Normal speed sign
      Speed SignThis sign is heavily used on all the Belgium roads. Outside of the populated areas the speed limit is mostly enforced with a 70km/h (about 44mph) speed sign.
