An in-car dash camera shows how quickly a crash can happen.

An Ionia Safety officer had just made a left turn when his patrol car crashed into a car pulling into a gas station.

Upon impact, the camera pointed up but the officer and woman involved in the March 13 crash can be heard. She was trapped in the car until firefighters could arrive to free her.

A state police investigation showed that the police car was traveling 21 mph when it crashed into the car pulling into the business.

The patrol car was a total loss.

The crash happened at North Dexter and West Main streets.

The police officer can be heard calling in the crash, and calming the other driver.

The other driver was cited for failure to yield.
