Abstract
An automatic turn signal monitor and warning device for use with a vehicle such as a motorcycle which requires manual deactivation of the turn signals. The device monitors turn signal activation which initiates a timer, and the timer activates a warning signal to remind the operator to deactivate the turn signal when the turn signal remains activated beyond an adjustable time interval after initiation. The warning signal can be produced by one or more audible, visual, or tactile mechanisms. The vehicle's hazard lights do not activate the device's timer, and the device's timer resets when the vehicle's brakes are applied. The device can be retrofitted onto an existing vehicle or included as original equipment when a vehicle is manufactured.
