The National Highway Traffic Safety Administration (NHTSA) is reminding pedestrians of all ages to walk with care – using crosswalks where possible – and urging drivers to be on the lookout for pedestrians at all times.

When noise is a problem, it’s usually in the “too much” rather than “too little” category. The opposite is true of ultra-quiet electric and hybrid vehicles, who emit so little noise that pedestrians and bicyclists may not be able to detect their presence, thus increasing their chances of an accident.
