I'll tell you what I was told to remember when I took my test... umm, years ago. Stay slightly under the speed limit. Obey all signs. If you do not understand an instruction, ask the person to repeat it nicely. "Huh?" or "What?" are not acceptable. Simply say, "I'm sorry, could you repeat that please?" or "Beg Pardon?" Take your foot off of the accelerator and cover the brake (meaning just have your foot over it, not on the peddle) at intersections, especially when other vehicles are waiting at them. Yield to pedestrian traffic. Signal every turn, every lane change and if they make you parallel park. Utilize your mirrors and for goodness sakes, look right, left, right when you need to. Really, it's all commons sense stuff. Drive like there was a cop behind you and you couldn't aford a ticket.
