Installing speed bumps as a traffic calming measure is far more effective when these are used in conjunction with clear signage. The Health & Safety Executive states the following:
Traffic-calming measures should be signed and clearly visible. Many features can be lit or made reflective. Take care when you are deciding where to use traffic-calming features, because they can sometimes increase risks (for example, by affecting the stability of vehicles or less secure loads).
Speed hump warning signs should be clearly visible, and should be far enough away from the hump to allow drivers to change their speed safely. The humps themselves should also be clearly marked.
