sleeping policeman  noun BritishA hump in the road intended to cause traffic to reduce speed.I am all for sensible traffic-calming, rumble strips, sleeping policemen and so on to keep traffic flowing, but these chicanes are a nightmare and should be dug up and replaced....- Still, demands persisted for speed cameras, radar traps, sleeping policemen, chicanes and other traffic management.
- Our roads don't need sleeping policemen - they have created a much cheaper way to slow the traffic down (plenty of holes in the road do the same thing).
