How far should you stay behind a motorcycle?

The correct choice of staying at least 3 seconds behind a motorcycle is appropriate because it allows for a safe distance that accounts for the unique handling characteristics of motorcycles. Motorcycles can stop more quickly than many cars, and the 3-second rule provides a reasonable buffer to react to any sudden changes in the motorcycle's speed or position. Additionally, this distance helps ensure that the driver has enough time to see and respond to potential hazards involving the motorcycle, including avoiding road obstructions or changes in traffic conditions.

Choosing a shorter distance would not provide enough reaction time, while a significantly longer distance might not be necessary unless conditions are particularly hazardous. This balance helps maintain safety for both motorcycle riders and drivers of larger vehicles.
