The general speed limits are as follows:
- 50 km/h (31 mph) within built-up areas;
- 90 km/h (56 mph) outside built-up areas;
- 120 km/h (75 mph) on roads with at least two two-lane roadways separated by a median, and on freeways.
The limits shown above apply only if there are no other signs present, as the signs may prescribe a lower or a higher speed limit. The speed limit outside built-up areas is in many places, especially in the Flemish Region, restricted to 70 km/h (43 mph). Around almost all schools, 30 km/h (19 mph) zones are found.
Drivers Licence and Insurance

Car insurance is Compulsory. Most western-european car insurances include Belgium, but it's always best to inform with your insurance company before you depart.
Apart from a valid drivers licence and an insurance certificate, you'll need to carry the vehicle registration documents as well with you. And of course a valid passport.
