To anticipate a hazard's impact, you should know its speed, distance, and direction.

• A. Its color
• B. Its weight
• C. The license plate
• D. Speed, distance, and direction

Answer: (D)

Anticipating hazards relies on understanding how the hazard is moving. Knowing its speed, distance, and direction lets you estimate how soon it could affect you and whether you have time to react, brake, or maneuver safely. Speed tells you how quickly the hazard is closing in; distance shows how far away it is now, which helps you calculate time to contact; direction indicates where the hazard is headed relative to your path, so you can judge if it will cross into your lane or stay away. Colors or plate numbers don’t inform motion or risk, so they don’t help you predict impact. With speed, distance, and direction, you can gauge time to collision and choose a safe response to maintain a prudent margin.
