A couple years ago we were going through Lake Havasu, The traffic was heavy and I was taking it pretty easy. The traffic light turned yellow up ahead and I was slowing down when some goof pulls over right in front of me and slams his brakes on hard enough to howl his tires.
Thank god for ABS brakes,the coach just planted itself just inches away from this guy.
One thing we did learn was that we pack things the right way because nothing went flying.
Years ago when I trained new drivers on heavy haul highway trucks one thing I would make them do was to make a panic stop at 60 miles per hr. It is a real eye opener even in a coach.
