This FAQ strengthens your understanding and supports accurate decision making for the Belgian driving theory exam in Belgium.
The C3 sign means that traffic is prohibited from entering the road or section in either direction. You must not proceed past this sign if your vehicle is covered by the prohibition. Always look for supplementary panels that might specify exceptions, such as for certain vehicle types, times of day, or distances.
The C3 sign generally prohibits entering, turning, parking, passing, or continuing on the road in a way that the sign forbids. It's crucial not to assume exceptions apply without a specific supplementary panel, and you must not rely on local habits if they contradict the sign's instruction.
You can only drive through a road with a C3 sign if a supplementary panel explicitly states an exemption for your vehicle category, direction, or manoeuvre. If there are no such panels and the sign applies to your vehicle, you must not enter and should choose an allowed route or wait for the prohibition to end.
A common trap is assuming the sign only applies in one direction or ignoring supplementary panels. Learners might also incorrectly assume that because a road looks usable, the sign doesn't apply. Always treat the C3 sign as a strict prohibition unless clearly informed otherwise by an accompanying panel or road markings.
You might see the C3 sign on roads that are closed to general traffic in both directions, perhaps for maintenance, special events, or because they are designated for specific users only (like pedestrian zones or cycle paths, though often those have specific signs too). It's essential to be vigilant and check for any signs indicating these exceptions.
