What action should you take when driving behind a motorcycle?

Maintaining a greater following distance when driving behind a motorcycle is crucial for several reasons. Motorcycles are smaller and can stop more quickly than larger vehicles, meaning that a driver needs to anticipate their speed and stopping capability. By keeping additional space, you provide yourself with more time to react in case the motorcycle slows down or makes a sudden move, which is more likely due to the maneuverability of motorcycles. This practice not only enhances safety for yourself and the motorcyclist but also allows you to see more of the road ahead, better assessing conditions and potential hazards.

In terms of the other options, staying too close to a motorcycle can lead to dangerously limited reaction time and may cause anxiety for the motorcyclist. Passing quickly without regard for conditions is dangerous and could result in a collision if there's unexpected traffic or obstacles. Lastly, while it's essential to be cautious about changing lanes, it is necessary to change lanes safely when required; just doing so without awareness or signaling can create hazards. Therefore, maintaining a greater following distance is the most prudent and safe option while driving behind a motorcycle.
