What is the speed limit in a school zone while children are present?

Answer: C — 20 mph unless otherwise posted

The speed limit in a school zone while children are present is commonly set at 20 mph unless otherwise posted. This limit is established to enhance safety for children who may be crossing streets or walking in the vicinity of schools. Reducing the speed limit in these areas helps drivers react more quickly to unexpected situations, such as children darting into the street or unforeseen obstacles. Local jurisdictions may adjust this speed limit, which is why it is important to be aware of any specific signage indicating a different limit. This rule reinforces the importance of vigilance and caution in areas where children are likely to be present.
