Thank you! Much appreciate it.

In Brussels and Wallonia - outside of the build-up area's [img]http://wegcode.be/images/stories/verkeerstekens/F/f3b_H.png[/img] :

120 km/h when there are 2 x 2 lanes, divided by a central reservation :!:
90 km/h anywhere else


There is no special speed limit with regular snow tyres - the general speed rules apply.
[Theoretically, there's also a speed limit depending on the tyre's speed rating, though I doubt you can still buy regular car tyres that aren't rated for at least 120km/h. Special tyres for oldtimers can be a rare exception.]

Till the end of this year: 90 km/hour if there are at least 2 x 2 lanes (divided by a central reservation or by a road marking).

1/1/2017:
In Flanders: If there are at least 2 x 2 lanes divided by a central reservation: 90 km/hour.
In Wallonia and Brussels-capital region: 90 km/hour if there are at least 2 x 2 lanes (divided by a central reservation or by a road marking).

On ordinary roads: 70 km/hour.

The max speed on regular roads with 2x2 lanes is 90 with studded or snow tyres. But is this true for both cases of central reservation and just a solid line between the two directions?
Thanks
