The Kennewick Police Department has released a traffic safety graph to drive home why people need to go slow in school zones.

KPD put out the information Thursday, explaining why such zones are only 20 MPH.  We know for some drivers it's an annoyance when they're in a hurry.

But according to these statistics, it makes a big difference. When a pedestrian is struck by a vehicle moving 20 mph, 9 out of 10 on average survive.

When you up that to 30 MPH the survival rate drops to only 5 out of ten, and when you move that up to 40 MPH, on average, only ONE out of ten pedestrians struck survive the crash.

The severity of this is why school zone tickets are so high as well. So slow down. This graph drives the point home.
