The C4b sign signifies the conclusion of a previously advised speed limit. It's an informational sign, meaning it doesn't impose a new mandatory speed but rather confirms that a prior recommendation has ended, and you can revert to the standard speed limits for the road you are on.
When you see the C4b sign, it means the advisory speed previously suggested by signs or road conditions is no longer in effect. You should prepare to adjust your speed if necessary, but the sign itself does not dictate a new specific speed; rely on the general speed limits and other traffic signals.
No, the C4b sign is an information sign, not a prohibition sign. It informs you that a previous advisory speed has ended. You must still obey all other traffic signs, signals, road markings, and general speed limits that apply to your location.
An advisory speed is a recommendation for a safe speed under certain conditions, often indicated by signs like C4b to signal its end, or by signs warning of hazards like curves. A mandatory speed limit is a legal maximum speed you must not exceed, enforced by law. The C4b sign marks the end of the former, not the start of a new mandatory limit.
While an advisory speed itself isn't a legally enforceable speed limit, driving significantly faster than advised could still lead to issues. If an accident occurs, driving at an unsafe speed, even if it was advisory, could be considered. The C4b sign simply confirms the advisory period is over.
Learners sometimes mistake information signs like the C4b for a new mandatory speed limit or a signal to immediately speed up. It's crucial to remember it simply marks the end of a previous recommendation and to always check for other signs or conditions that dictate your actual speed.
