I think its important to know the concepts and also be able to practice them at work. Its fine too if you can recite them word for word but I don't think we should be required to do so. I say this because I know there are a percentage of drivers with learning disabilites and they CAN'T memorize the stuff.
Oh, did you hit the nail on the head! If you are trained on the concepts of the various principals, wouldn't you not only be more inclined to know them, but apply them?
OK, class is in session. I say that when approaching an intersection, that you should look left, right, left
as a minimum. Here are some examples that you might want to look more than left, right, left:
1) if the intersection is somehow at a unusual angle, or if the intersection has more than four streets.
2) if your professional driving experience tells you that the intersection is particularly dangerous.
3) if the intersection has places of business very close to the actual crossing
4) if you are unsure of the traffic light pattern
5) if there are pedestrians on the corner.
I bet you guys could come up with many more, especially in a classroom setting with A QUALIFIED TEACHER. Experience something like this, and you will never miss this principal when asked to regurgitate the 10 point commentary.
I've said it before, but it is worth repeating: I am trained better (light years better) to referee hockey games for eight year olds then I am to be a UPS driver.
