When following vehicles that often stop or turn suddenly, what is the recommended action?

Increasing your following distance when behind vehicles that frequently stop or turn suddenly is essential for maintaining safety on the road. This practice provides you with more time to react to unexpected situations. By having a greater distance between your vehicle and the one in front, you can better anticipate potential hazards, such as sudden stops or turns, and allow yourself a larger buffer for braking if necessary. This additional space is particularly important in urban environments or when driving behind buses, delivery trucks, and other vehicles that are often required to make quick maneuvers.

The other options emphasize reducing or maintaining distance, which may not provide adequate safety margins when dealing with unpredictable driving behavior. Changing lanes frequently could also create further risks, as it may lead to additional distractions and potential conflicts with other vehicles.
