What does this sign mean?

Explanation: If you're in a place where there are likely to be pedestrians (for example, outside a school, near a park, in a residential area or in a shopping area), you should be cautious and keep your speed down. Many local authorities have taken steps to slow traffic down by creating traffic-calming measures such as road humps. They're there for a reason; slow down.
