A 22-year-old woman hyperventilates every time she drives over a bridge and slows to a dangerously low speed. She tries to rationalize her reaction by explaining that she is just being cautious and protecting herself from traffic, but the hyperventilating and slow pace is dangerous. She realizes that this is irrational but is unable to control it. She becomes extremely anxious at the sight of a bridge, even when a passenger in the car, and worries for days before a car trip where she knows she will have to cross a bridge.
