If you see a regulatory sign (like a speed limit or prohibition) or a signal with the C25b, you must obey the stricter instruction from the regulatory sign or signal.

Not necessarily. The C25b sign provides information about speed limits, but the actual requirement to reduce speed depends on any accompanying regulatory signs or the actual speed limit displayed. It prompts you to be aware and prepare to adjust your speed if indicated, rather than demanding an immediate change without further instruction.
