In plain English
Children are unpredictable and small enough to hide between parked cars. Drop your speed and scan low — feet under cars are often the first clue.
Where you'll see it
Near schools, playgrounds and parks. Sometimes paired with a flashing amber light at school times.
The common trap
Treating it as a school-hours-only sign. Children use these roads in the evening and at weekends too.
Memory anchor
Two figures hand in hand — where there's one child, expect another right behind.
