Alabama Boating License Practice Test

The main function of an ignition safety switch is to shut off the engine if the operator is thrown overboard. This safety feature is important for boats, as it can prevent accidents and potentially save lives. Options A and D, improving fuel efficiency and making the boat go faster, are incorrect as these are unrelated functions to a safety switch. Option B, enhancing the audio system, is also incorrect as it does not pertain to the main function of the safety switch. It is important to prioritize safety measures on a boat over other potential features.
