Final answer:
The recommended following distance when following a motorcycle is a 2-second distance.
Step-by-step explanation:
The recommended following distance when following a motorcycle is a 2-second distance. This means that you should keep a distance equal to the amount of time it would take for the motorcycle to pass a fixed point after the car has passed it. For example, if the car passes a tree, you should count how long it takes the motorcycle to pass the same tree and make sure that at least 2 seconds have passed. This allows for a safe stopping distance and gives you enough time to react to any sudden changes.
