Chapter 2: The public highway

What is the highway?

Motorway designates a public road whose beginning or access is indicated by sign F5 and whose end or exit is indicated by sign F7.

The highway is a two-way public road divided into 4 or more lanes with at least two lanes in the same direction and whose directions of traffic are separated by a central berm.

What is the emergency lane?

The emergency lane is a lane reserved for broken down vehicles on a motorway or on a road for automobiles.

It is located on the right of the roadway and is separated from it by a wide, continuous white line.

On the emergency lane it is prohibited to:


Failure to comply with the above prohibitions will cause you to lose 5 points in the theoretical exam.

Driving without reason on the emergency lane constitutes a third degree offense, which will cause you to lose 5 points during your theoretical exam.

Who are prohibited from driving on the highway?

Access to the motorway is prohibited to:

moped drivers
riders, harnessed vehicles and other animal drivers
to drivers of vehicles towing another vehicle
agricultural vehicle drivers
fairground vehicle train drivers

Où monter sur l'autoroute ?

Vehicles admitted to motorway traffic can only access or exit from specially designated areas.

How to get on the highway?

When getting on the highway, you must accelerate on the launch strip so as to quickly reach the minimum authorized speed in order to be able to merge into traffic, without disturbing the drivers traveling there.

In addition, priority must be given to drivers already engaged.

What speed should you respect?

The motorway is the only public road on which a minimum speed is imposed.

When traveling on the motorway the minimum speed is 70 km/h.

While the maximum speed is 120 km/h.

On the Brussels Ring Road, the limit is 100 km/h.

Cependant, à l’approche d’un virage ou de travaux, une limitation de vitesse inférieure peut être imposée.

In certain locations, the maximum authorized speed will only apply on one or more traffic lanes or only on the exit ramp.


On the motorway it is prohibited to:

turn around
travel in the opposite direction
tow a vehicle
use the cross connections

All these offenses are 4th degree offenses which will cost you 5 points during the theoretical test and will result in disqualification from driving.

Other prohibitions:

the processions
demonstrations and gatherings
advertising parades
sporting events or races

Place on the road

On the motorway you must stay as close as possible to the right edge of the road.

Unless there is heavy traffic, you can therefore choose a lane.

Or when you have to comply with directional gantries to follow a given destination.

In case of density, bikers are authorized to move up the lines between the two left lanes.

Their maximum speed must be 50 km/h and the difference between their speed and the speed of the vehicles they are overtaking cannot exceed 20 km/h.

For example, if the speed of the vehicles being raised is 20 km/h, the bikers will travel at a maximum of 40 km/h.

Please open a lane for them and look in the rearview mirror every 5 to 10 seconds.


Overtaking on the motorway is always done on the left.

After overtaking you must immediately move to the right lane unless you wish to overtake several vehicles at once.

The driver who complies with the directional gantries or the choice of lane in the event of heavy traffic can pass to the right and this movement is not considered as overtaking.


On the motorway, it is allowed to overtake, which means overtaking a vehicle that is overtaking.

La bande "heure de pointe"

The rush hour lane is a lane located on the right of a motorway roadway.

It is recognizable by its ground marking consisting of a white line made up of long discontinuous lines.

It is open to traffic with a green arrow pointing down.

And closed to traffic with a red cross placed above the strip.
