Children and families are big winners from slower speeds. Wide 20mph limits help parents and children to get around locally. Less danger or parent ‘taxi – duty’ and more walking and cycling means happier, healthier families with extra money to spend.

Child protection should focus more on slower speeds because crashes are the top avoidable cause of early death or injury for 5 – 35 year olds. Some children are not allowed to go out without an adult because of fears of being run over.

Just 20% of child casualties happen on school journeys. Yet until recently transport officials had focused on engineering slower speeds with humped, school zones. But, humps are costly. They result in confusing limits. Zones only protect a few hundred metres near schools (about 17% of a school trip). Zones encourage parents to drop off in the “safe area” and then remind them to speed up on leaving it. Wide 20mph limits are better because people who walk or cycle the journey enjoy a 20mph limit throughout the majority of their route.
