Abstract: A proximity alert system includes a vehicle that may be driven on a roadway. A proximity alert is coupled to the vehicle and the proximity alert detects obstacles around the vehicle when the vehicle is driven on the roadway. The proximity alert is electrically coupled to the turn signal such that the proximity alert is turned on when the turn signal is actuated. The proximity alert generates an alarm sequence when the turn signal is actuated and the proximity alert detects the obstacle. Thus, the proximity alert alerts a driver of the vehicle to the presence of the obstacles when the vehicle changes lanes on the roadway. The proximity alert generates an all clear sequence when the turn signal is actuated and the proximity alert does not detect the obstacle. Thus, the proximity alert facilitates the driver to safely change lanes on the roadway.
