C20b - Fim da limitação de velocidade (Fim da limitação de velocidade) belongs to the Portuguese prohibitory signs category in the Regulamento de Sinalização do Trânsito. It normally uses the red-bordered regulatory style associated with restrictions, limits, bans, or cancellation of a previous restriction. The official wording is: fim da limitação de velocidade: indicação do local a partir do qual é permitido circular a velocidade superior à imposta pelo sinal C13. It creates a binding restriction from the point where it applies and normally continues until it is ended, replaced, or limited. For theory preparation, connect the sign to a concrete driving decision: where to look, when to slow, whether to stop or yield, which route or lane to choose, and whether any panel changes the scope of the rule. On the road, interpret it together with markings, traffic lights, police directions, temporary works signs, and any additional panel placed with it. A strong exam answer explains both recognition and behaviour: not only what the sign is called, but what a safe and lawful driver must do next.

The C20b sign means that any speed limit that was previously in effect, often indicated by a sign like C13, no longer applies. You are now allowed to increase your speed, provided it is safe and within legal limits for the road type and conditions.
No, the C20b sign signifies the opposite. It indicates that you can now drive at a speed higher than the one previously imposed. Always ensure your speed is appropriate for the current road and traffic conditions, even after seeing this sign.
A speed limit sign, like C13, imposes a maximum speed you must not exceed. The C20b sign, conversely, lifts that restriction, allowing you to drive faster than the previous limit, but you must still adhere to general speed regulations and any new limits indicated by subsequent signs.
A common trap is confusing the C20b sign with a sign that *imposes* a speed limit. Learners might incorrectly assume they still need to drive slowly. Always remember C20b means the *previous restriction has ended*, and you can increase speed, but safely and legally.
No, the C20b sign only cancels a *previous, specific* speed limit. You must still adhere to the general speed limits applicable to the road you are on (e.g., urban, rural, highway) and any new speed limits indicated by other signs or traffic conditions. It simply removes the prior, lower restriction.
