The study aimed to design a device which can limit the speed of the motorcycle when the driver does not wear a helmet. The device consisted of a modified capacitor discharge ignition (CDI) that was responsible for the speed limit and a transmitter and receiver module for the helmet detection. This study sought to address the following issues: (a) the immediate response of the device and (b) its durability when the accident occurs.
Experimental development and descriptive approaches were the methods used. Fifteen purposively chosen evaluators were requested to assess the speed control system.
Findings revealed that the device was effective to limit the speed of a certain motorcycle model and was satisfactory in automation and operation.
