Before the motorcycle stops, what should you do with the handlebars?

Answer: D — Square them so the motorcycle can be more easily held up

When coming to a stop on a motorcycle, it is important to square the handlebars so that the motorcycle can be more easily held up. By having the handlebars squared to the direction of travel, the motorcycle will be in a stable position, making it easier for the rider to maintain balance and control. Turning the handlebars left and right alternately, keeping them straight, or turning them all the way to the left can lead to instability and potentially cause the motorcycle to tip over. Therefore, squaring the handlebars is the correct technique to ensure a safe and stable stop.
