Trochophobia

Tophobia (from Latin t meaning "t") is the fear of being on a t or b. The phobia is usually triggered after knowing that t or b is more vulnerable to flipping over on its side, and by seeing on the news or in person a t or b is knocked over with injuries and sometimes even deaths in its wake. Sufferers would not take a b to and fro school, instead they rely on parents or guardian to drive them to and fro school via c. When they go on a field trip, sufferer would insist a teacher to drive there.
