Our speed breakers or bumps usually have a gap or two in them and I go through the gap. Even when they don't I usually go around the end of them. I only go over them when there is no choice. Butt off the saddle and sometimes a hop to ease the weight off the front.

Back in ROTC I always wondered while having to do the obstacle course why a normal thinking person wouldn't go around any obstacles encountered in real situations. Our drill instructor didn't think it funny.
