safe-driving
When is the Illinois school-zone speed limit 20 mph in effect?
- Every day from sunrise to sunset near any school
- Only when a crossing guard is directing traffic
- On school days from 6:30 a.m. to 4 p.m. when children are present and signs are posted
- From 4 p.m. until 6:30 a.m. on school days
Answer: On school days from 6:30 a.m. to 4 p.m. when children are present and signs are posted. The 20 mph school-zone limit applies on school days between 6:30 a.m. and 4 p.m. when children are present and signs are posted. It is not an automatic sunrise-to-sunset rule, and a crossing guard does not create the entire time window. Look for the marked school zone and confirm the posted sign before choosing speed. The rule combines the time, school operation, children present, and signage conditions, so leaving out any of those conditions changes the answer.
