What should you do if another vehicle is too close to you while riding?

Answer: D — Increase your following distance and remain aware

When another vehicle is too close to you while riding, increasing your following distance and remaining aware is the best course of action. This approach allows you to create more space between you and the vehicle, which can provide you with additional reaction time in case of an unexpected situation. Maintaining a greater distance not only enhances your safety but also gives you a better ability to maneuver if needed. Being aware involves constantly monitoring your surroundings, which is crucial for anticipating the actions of other drivers. This heightened awareness could involve looking for escape routes or evaluating how other vehicles are moving. It is always better to prioritize safety and maintain control of your riding situation, rather than relying on quick maneuvers or communication that might not guarantee the response you'd hope for from other drivers.
