When a disabled person or someone with visibly reduced mobility enters a pedestrian crossing with a special sign, should you anticipate having to stop your vehicle?

Why?

You must stop to let a disabled person using a special identifying sign, or someone with visibly reduced mobility, cross the road. Slow down as you approach the crossing and be ready to stop, since they may need more time to cross.
