A trailing vehicle may not recognize a braking actionin time to respond appropriately. Also, cruise control will reengage uponrelease of the brake pedal and resume the set speed. In either case, it couldresult in a crash without prior warning.
Brake stoplamps may not illuminate or, in some cases, stoplamps will not stay illuminated all the time when brakes are applied due to a faulty stoplamp switch. Also in vehicles equipped with cruise control, a faulty stoplamp switch can result in resumption of the cruise control function upon release of the brake pedal.
