Motorcycles require more space when following because they have the ability to stop faster than cars, making it essential for you to have sufficient stopping distance to react safely. This extra space is crucial to avoid collisions if a motorcyclist needs to brake suddenly or if they encounter instability on the road. Additionally, due to their single tail light and smaller profile, motorcycles can be harder to see at night, making it even more important to maintain a greater following distance to ensure their presence is clear and that you can react responsibly.
