In 1 direction there are sign of maxspeed 50, in the other there are no signs, except for 2 sign:
- Just before Rue de la Grenouillette - Waterranonkelstraat there is a sign saying 30, but I'm not sure it's a permanent sign.
- At the intersection of Rue du Planeur - Zweefvliegstraat, there is a sign 30 with herhaling/rappel, followed 20 meter further by a sign 50.

So examples in the direction of Haacht:
