Traffic mirrorBelgium

No. A traffic mirror is roadside equipment and does not have its own numbered sign or regulatory meaning in the Belgian Highway Code.

No dedicated traffic-mirror sign is included. Traffic mirrors remain visibility equipment rather than regulatory traffic signs.

No. Drivers must continue to follow B1, B5, traffic lights, priority from the right and every other applicable priority rule.

Yes. Sign B5 requires a complete stop. The mirror may be consulted only as an additional aid after the mandatory stop.

Yes. A driver subject to B1 or B5 may proceed only when this can be done without danger to road users who have priority.

No. A cyclist, pedestrian, moped, motorcycle or vehicle may be outside the reflected area or hidden by distortion, weather or glare.

No. Drivers must exercise extra caution when entering an intersection and should check the road directly as far as the road layout permits.

No. The applicable speed limit remains in force, but drivers must adapt their speed to the restricted visibility and remain able to stop safely.

The road authority responsible for that road decides whether the installation is authorised and appropriate.

No. Responsibility may lie with the municipality or the relevant regional road authority, depending on who manages the road.

A person may install a mirror within their own private property, subject to property and local planning rules, provided it does not obstruct or endanger public-road users.

Prior permission from the responsible road authority is required when the installation occupies or affects the public road or its roadside equipment.

Not without authorisation. Placement on or across the public road requires approval from its managing authority.

No. Walloon technical guidance treats their installation as exceptional and recommends first considering more reliable measures that improve direct visibility.

Possible measures include trimming vegetation, removing or relocating visual obstructions, changing parking arrangements, adapting traffic directions or redesigning the intersection.

Walloon guidance allows it only in restricted circumstances, including a branch controlled by B5, severely limited visibility, no better available solution and a short distance between the stop line and the mirror.

The recommended distance between the stop line and the mirror is less than 15 metres.

The guidance specifies a free height of at least 2.20 metres beneath the mirror so it does not obstruct pedestrians.

Yes. The installation may not hinder pedestrian movement. Walloon guidance generally refers to approximately 1.50 metres of unobstructed passage, depending on the location and pedestrian use.

The mirror is provided with a clearly visible frame using alternating red and white bands so it can be distinguished from the background.

Parking near the mirror should be avoided where a parked vehicle could block its reflected view, particularly when the vehicle is high.

Yes. It should be cleaned, inspected and correctly aligned. A shifted, damaged or obscured mirror can provide misleading information.

Where a public-road mirror is exceptionally authorised for a private access, the applicant may be responsible for the installation and maintenance under the authority’s conditions.

The convex surface makes vehicles appear smaller and farther away. Drivers should assume that approaching traffic may be closer and faster than it appears.

Headlights reflected in the mirror may make a vehicle appear to approach from another direction or make its speed and distance difficult to assess.

Treat it as unavailable. Stop or give way as required and proceed only after obtaining enough direct visibility to enter safely.

Do not rely on the image. Report the problem to the municipality, regional road authority or other responsible manager.

Yes. Drivers must immediately follow lawful instructions from police or another authorised person, regardless of the reflected traffic image.

No. Drivers will continue to be responsible for adapting their behaviour to visibility, road conditions and other road users and for obeying the applicable priority rules.
