Looks like physics dictated the outcome,

The smaller car was able to negotiate the turn, while the heavier, larger cruiser was tugged away from its' preferred path. Fortunately, he did not take it broadside.

I believe it was brake fade.

So... what I know all of us are wondering. How much paperwork does it take to take the "edge" off that incident? I'm sure your partners would not let you live that down for a while though.

As long as nobody was seriously hurt, and I don't believe they were,that is classic retirement party material presented along with a gift certificate from the store.

Understeer.

With out getting into specific policies or training, I was curious if you might be able to elaborate more on what causes this?

Understeer is the front tires inability to turn the car because you're asking them to provide traction they can't provide. A tire is only capable of 100% traction at any moment (between turning, accelerating, braking). If you're asking the tire for 90% braking, and then you try to throw in another 25% to turn, the tire will do neither.



Very likely to front wheel/all wheel drive cars, very heavy cars, or cars with more weight on the front than the rear.

Brake fade is caused by brake pads/fluids/rotors getting too hot from excessive use in a short amount of time, and it will considerably increase your stopping distances. This happens often to heavy cars, a prime candidate being a loaded down police edition crown vic.

Thank you! Great links and video!

Yeah,,,, what he said. It was a little of one and a lot of the other, or the other way around.

In my opinion, the cause was improper position prior to the turn. High visual horizon and proper position are the keys to high speed driving.

Looked like the wall was made out of paper or something :rolleyes:

[roaming_gnome]

I remember this vid.... I was on vacation in Hawaii..... I got up, had a cup of coffee, got the paper, turned on CNN..... I remember thinking to myself... "Boy, how much does that have to suck to be in high management and find out via CNN."

Anywhoo... some time ago the cars got new hub caps. The new hub caps, the size of dinner plates, didnt allow the proper air flow to the brakes, thus, the collision. In the vid, you can see that the officer is on the brakes, but they did not slow down.

Soon after that, all the hub caps were changed out to the smaller "dollar size" hub caps.

Brakes just have not seemed as good since asbestos was prohibited. Do CHP cruisers get any special options on brakes?

I think all of the above are correct, but I will add - tunnelvision. Seems like the officer could have recovered by cutting back to the left once it became obvious he/she wasn't gonna make it.

Glad the officer is okay. God knows I've pulled a couple of Dukes of Hazard moves that I was lucky to walk away from. Thankfully, those moves never made YouTube :biggrin:.
