The C20g road sign in Portugal means that a specific action, such as entry, movement, parking, stopping, overtaking, or a speed limit, is prohibited. You must comply with this restriction until it is cancelled or modified by another sign.
The C20g sign prohibits specific actions that will be indicated by the sign itself or any accompanying panel. This could include a particular manoeuvre, vehicle category, speed, or parking/stopping. You must not perform the forbidden action.
When you see the C20g sign, you must understand what specific action is forbidden and cease performing it. Look for any additional panels that clarify the restriction, such as which vehicles it applies to. Continue driving only if your vehicle and intended manoeuvre are outside the scope of the prohibition, or choose an alternative route.
A common exam trap is assuming a prohibition applies to all vehicles or situations. Always check for supplementary panels that might limit the prohibition to specific vehicle types (e.g., lorries, motorcycles) or specific actions. Another trap is forgetting that the restriction remains in effect until an 'end of prohibition' sign is displayed.
If there's an additional panel with the C20g sign, it's crucial to read it carefully. This panel will specify the exact nature of the prohibition or the vehicles/situations it applies to. For example, a panel might state the prohibition only applies to vehicles over a certain weight or only during specific hours.
The prohibition indicated by the C20g sign continues until it is explicitly ended by a 'no longer prohibited' sign (such as C21g), replaced by a different restriction sign, or limited by another sign. Always be aware of subsequent signs that might alter or cancel the restriction.
