The C3s road sign in Portugal indicates a prohibition. It means you must avoid a specific action that is forbidden by the sign, such as a particular type of vehicle entry, manoeuvre, parking, stopping, or speed. You must comply with this restriction until it is ended or modified by another sign.
When you see the C3s sign, you must immediately understand what specific action is prohibited. You should then cease that action or avoid it entirely. If the sign forbids entry, you must not proceed past it in that manner. If it forbids parking, you must not park there. Always look for supplementary panels that might refine the prohibition.
A common mistake is not paying attention to supplementary panels which often specify which vehicles or manoeuvres the prohibition applies to. Learners might also assume the prohibition is advisory rather than mandatory. It's crucial to remember that prohibitory signs create binding rules that must be followed to pass the theory test.
Not necessarily. While the C3s sign itself indicates a prohibition, supplementary panels attached to it can significantly alter its scope. These panels might specify that the prohibition applies only to certain vehicle types (like trucks or motorcycles), or certain actions (like parking or overtaking). Always read any accompanying panel carefully.
The restriction imposed by the C3s sign remains in effect until it is explicitly ended, replaced, or limited by another traffic sign. This could be a 'end of prohibition' sign, a sign that introduces a new restriction, or a sign that modifies the scope of the current one. You must remain aware of subsequent signs.
