I drove school busses for 5 yrs.
Quite a bit different then the tour/charter busses your talking about. But similar in some ways also....heres what i can tell ya...
1- Avoid sharp manuevers. Escpially at speed. They are top heavy. I dont know about charter busses they seem to sit lower, but school busses can be very tippy.
2- Dont pull out in front of anyone. The 5.9L B series cummins in the INt'l's i drove did the job, but slowly. Later on i landed one with a 8.3L Cummins, it scooted decent, but still wasnt a thrill ride.
3- Watch for idiots. People will cut you off, run in your blind spots, tailgate, anything they can do to piss ya off. I had a metro pull out infront of me one time when i drove bus, he pulled out with about 35ft of room or so, didnt even look. I creamed the car doing 45mph, luckly no on was hurt.
4- Try to operate them smoothly. Nothing pisses of passengers more then getting jerked around.
5- Be easy on there trannys. There under enough stress as it is.
6- Learn to use your mirrors for backing up. Thats about the only way you can back a bus up.
-if you wanna know anything else, lemme know.
later,
Dustin
