What does the school zone maximum speed sign mean?
Obey the lower maximum speed shown in the school zone
This is a school-zone speed sign. The speed limit in the zone is lower than normal. Obey the maximum shown (here 40 km/h), especially when the yellow lights are flashing or during school hours.
Why the other answers are wrong
-
The minimum speed in the zone is 40 km/h
The sign says MAXIMUM, so 40 km/h is the fastest you may go, not the slowest. School zone limits are set lower, not higher, during school hours.
-
School is closed; normal speed applies
This sign never announces a closure. It posts the lower school zone limit that applies during school hours, so drive no faster than the number on the sign while the yellow lights flash.
-
No vehicles over 40 km/h capability are allowed
A speed sign controls how fast you drive, not what your vehicle is capable of. Bans on a type of vehicle appear inside a red circle with a line through the symbol.
Quick way to remember
Read the number and unit; the colour tells you where you are.
