The school zone speed limit is enforced from the first sign you see until you pass the crosswalk, then you may accelerate to the posted speed limit
Your front bumper may not pass another vehicle’s front bumper until you pass the crosswalk
You must stop for children crossing the street
In addition to these legally enforceable rules, you should also be very aware of your surroundings when driving near a school zone. Some children may dart out into traffic or in other ways attempt an unsafe crossing. Stay alert!
