4.1. Engine Cutoff Switches on Boats: A Precedent for Safety
One notable example is the federal law that went into effect on April 1, 2021, requiring the operator of a boat to use an engine cutoff switch link. These links, often in the form of a coiled bungee cord lanyard, are wrapped around the wrist of a boat operator and connected to the boat’s kill switch.
In the event of ejection or a fall inside the vessel, these links will disconnect from their port and subsequently cut power to the boat’s engine. This can significantly reduce the risk of injury to the boat’s occupants. For example, a typical three-blade propeller spinning at 3,200 rpm can inflict about 160 impacts in one second. In addition, a person ejected from a boat may be stranded in open water if the boat’s engine were to continue running, sending the unoccupied boat far away from the individual.
4.2. Implications for Automotive Kill Switch Legislation
The existing law requiring engine cutoff switches on boats provides a precedent for the use of kill switches in other types of vehicles. It demonstrates that the government is willing to mandate the use of technology to improve safety and prevent injuries.
However, there are also some key differences between boats and cars that need to be considered. For example, cars are typically operated on land, while boats are operated on water. This means that the risks associated with a malfunctioning kill switch may be different for cars and boats.
4.3. Potential Expansion of Kill Switch Laws
It is possible that the proposed mandate for kill switches in new cars could lead to the expansion of kill switch laws to other types of vehicles and equipment. For example, there has been some discussion of requiring kill switches on motorcycles and other recreational vehicles.
Ultimately, the future of kill switch laws will depend on a variety of factors, including the success of the proposed mandate for new cars, the development of new safety technologies, and the public’s acceptance of these technologies.
