Dramatic video of a crash caught on a squad car dash camera.
A State Trooper pulled a car over for a defective headlight Tuesday night on I-41 near Kaukauna.
Moments later a Pontiac slams into the back of the stopped car.
Both drivers were injured. One was taken to the hospital.
The other now faces charges for causing the crash.
The State Patrol says this video is a reminder of the importance of Wisconsin's Move Over Law, which requires drivers to change lanes or slow down when vehicles are on the side of the road with their warning lights flashing.
