The present invention is a system and method for stopped vehicle driver alert. The system gives alert to the driver at traffic light when a vehicle is stopped at red light, when the light changes from red to green, and/or when the front vehicle clears out moving away above a threshold distance. In preferred embodiments, system comprises optical sensors to detect traffic lights and changes of traffic light status, object detection and object distance measurement sensors, GPS location sensors, a microprocessor with memory, engine control module, and alert systems capable of playing or displaying alerts of audible, visual, and haptic formats. The system is also capable of generating engine start signal. The method detects if the ego vehicle is stopped due to a traffic light and/or traffic jam or a scenario where the front vehicle is almost stopped or within a threshold distance from the ego vehicle. When the condition changes. If the traffic light is red the method determines how long the red light will exist before changing to green with the help of precalculated table where red light duration of a particular GPS location on a particular road is given. The method also calculates a complete red light duration of it can detect the start of the red light and update the red light duration. The method generates remaining light duration signal and send the signal to audible or visual alert systems. Right before or after the remaining time turns to zero, the method generates audible, visual, and/or haptic signals and sends the signals to the audible, visual, and haptic alert systems and/or sends engine start signal to engine control module. The method also determines if red light changed to green and sends audible, visual, and/or haptic signals and/or engine start signal to engine control module.
