speed when leaving the built up area in Brussels

[ZAW]

I am requesting clarification on these questions, please:

1) Is the definition of "ordinary road," "normal road," and "regular road" the same?

2) The June 2021 edition of the book states in Lesson 6 that the speed limit when leaving a built-up are in Brussels region is 70 kph. Meanwhile, the online update says, "The maximum speed (1/1/2017) on an ordinary road in the region Walloon and Brussels-capital: 90 km/hour.

My exam is tomorrow and I would appreciate any clarification as soon as possible Thank you.

Please stop using an old book (June 2021. It means written in 2020) with old traffic rules. On the site www.drivinglicence-belgium.be you can find the uptodate theory.

1. The same.
2. Flanders and Brussels region: 70. Wallonia: 90.
