5. Built-up area

A built-up area is an area containing concentrated buildings, streets and regular local activity. Drivers should expect more pedestrians, cyclists, intersections, parked vehicles, public transport and vehicles entering or leaving properties.

Many countries apply special traffic rules and lower default speed limits within built-up areas. The area may be identified by entrance and exit signs, street lighting or other legal criteria, so drivers must follow local signs and regulations.

How can you recognise a built-up area in Belgium?

A built-up area begins at a built-up-area sign showing a buildings symbol, which may also display the place name. It ends at the corresponding end sign. After that sign, the rules applicable outside built-up areas take effect unless another sign indicates otherwise.

What is the speed limit in a Belgian built-up area?

The general maximum speed is 30 km/h in the Brussels-Capital Region and 50 km/h in the Flemish and Walloon Regions. A traffic sign may impose or permit another speed, and lower vehicle-specific limits may still apply.

Must you allow a bus to leave its stop?

Yes. Inside a built-up area, a driver travelling in the same direction must allow a bus or trolleybus to leave its stop when its driver indicates the intention to move off. You must slow down and stop if necessary.

How much space must you leave when passing a cyclist?

Inside a built-up area, a car or motorcycle driver must leave at least one metre between the vehicle and a cyclist or rider of a two-wheeled moped. Outside a built-up area, the minimum distance is 1.5 metres.

Where should you place a warning triangle inside a built-up area?

The warning triangle is normally placed at least 30 metres behind the vehicle on an ordinary road. Inside a built-up area, when that distance cannot be maintained, it may be placed closer to the vehicle or, when necessary, on the vehicle.

How do Belgians refer to a built-up area?

The official Dutch term is bebouwde kom. The French term is agglomération. In traffic law, the entrance and end signs determine the boundaries of the built-up area.
