Build a Safe Road

What is this experiment about?

This street is missing its safety features. Drag each one — a crossing, a light, a bump, a sign — onto the spot where it belongs.

Questions kids ask

What does a speed bump actually do?

It gently jolts a car, so drivers naturally slow down without needing to be told.

Why do crossings need painted stripes?

The stripes make the crossing spot obvious to drivers from far away, even at a glance.

Do all streets have all four features?

No — engineers choose features based on how busy and fast a particular street is.
