The next time you see your school lollipop man or woman, make sure you stop to say "happy birthday".
It's 50 years since the first crossing attendants took to streets to help kids stay safe when walking to school.
As they celebrate their 50th birthday, statistics prove they have made a valuable contribution to road safety.
In 1953, when there weren't as many cars around as there are today, 797 kids were killed on the roads. That figure had dropped to just 179 by 2002.
