UK health body proposes removal of speed bumps to cut air pollution

Variable speed limits, removal of speed bumps and 'no idling' zones near schools among Nice recommendations

Speed bumps should be removed, speed limits made variable on England's motorways, sometimes dropping as low as 50mph, and a congestion charge considered in more cities to cut air pollution and save lives, health experts have said.

The National Institute for Health and Care Excellence (Nice) released a series of recommendations on Thursday which it said would "promote a smoother driving style" and help keep emissions down.
