This study developed a system that can prevent car collision through an early warning device capable of measuring the distance of the obstruction detected in front or at the back of the car. Also, it had the ability to detect appropriate use of seatbelt and presence of liquor near the driver's position to disable the engine; thus ensuring the safety of the people inside the car and thereby reducing the probability of car accident.
Experimental development method was utilized to construct the system. This was followed by a descriptive method to evaluate the functionality of the design. Ten purposively chosen evaluators were asked to participate in the study.
Findings of the study indicated that the device was able to measure the distance of the obstruction and to display the data on the LCD and to detect the presence of liquor and disable the car from starting. Furthermore, the device was able to detect whether the seatbelt is fastened or not and could play the voice-prompt-alert.
