Why should a motorcyclist maintain a larger following distance (such as a minimum two-second gap, increased in poor conditions) behind the vehicle ahead?

A motorcyclist should keep at least a two-second following distance under good conditions, and more in rain, traffic, or at higher speeds. Adequate following distance gives the rider time to see a hazard developing ahead, and the space to brake smoothly or swerve without a sudden, traction-breaking maneuver. Because a rider is far more vulnerable than a car occupant in any collision, that extra cushion is critical. The gap also keeps the rider out of the lead vehicle's blind spot and provides a clearer view of the road ahead. More space means more time to react safely.
