Karen – really, as long as your supports are there and glued down as it was, if you drive carefully, you should be fine. The mom admitted to a very hard turn out of a gas station and knew when it happened. I’ve transported 4 tier cakes with no problems but I drive like an old geezer the entire way! A center dowel could be used of course, but I never center dowel three tier cakes.
