Skid Marks

Last week we had a class on accident investigation. This was our first out of the classroom, hands on lecture. We of course had some time in the classroom, learning how to preserve the scene, the steps we go through if we are the first on scene, and also how to judge the speed a vehicle was going by looking at the skid marks on the road and other evidence that is left behind at the scene of a crash.

We had three instructors from the Westminster Police Department teach us, all of them had extensive knowledge on the subject, as well as a lot of experience in the field. We discussed real life accidents, looking at pictures from the scenes, and had explained to us the chain of events that caused the accident based on our instructor's personal investigation.

When we got out of the classroom, our first project was to examine skid marks, this was really cool. One of the instructors got into a patrol car at a safe location, and performed some high speed braking for us. We would then examine the skid marks, judge what mark was left by the rear tires, and what were left by the front tires. We would measure the length of the mark and calculate the speed of the vehicle at time of braking.

The next exercise that was set up was a mock accident. Two vehicles were set up on a public sidewalk, there were skid marks in the road, and we had witnesses to question. Apart from actually having an accident, this was as close to the real thing as they could make.

We were set up into groups, assigned responsibilities and sent on our way. My job, along with my partner Eric, was to take measurements from the accident, judge the point of impact, and relay our info back to the team so we could get a full picture of what happened. Once we had taken all the information, we then went back to the class room to write an accident report form, and decide who was at fault in the accident, and what charge we were going to cite them with.
