What should you do if you notice another driver behaving erratically on the road?

Answer: B — Give them extra space

Giving extra space to a driver who is behaving erratically is the best course of action for ensuring safety on the road. Erratic behavior can indicate various issues, such as impairment, distraction, or stress, which can lead to unpredictable driving patterns. By increasing the distance between your vehicle and the erratic driver, you reduce the risk of a collision and provide yourself with more time to react to any sudden maneuvers they might make. Maintaining this space allows for greater awareness of the situation and provides an opportunity to safely maneuver away from potential danger. It's important to prioritize safety over the desire to maintain speed or engage with the erratic driver, which could escalate into more dangerous scenarios.
