Which of these statements about speed management is true?

• A. You should choose a speed that lets you stop in the distance you can see ahead
• B. You should always drive at the posted speed limit regardless of conditions
• C. You should speed up to maintain traffic flow
• D. You should ignore weather conditions when setting speed

Answer: (A)

Speed management means choosing a speed that lets you stop safely within the distance you can see ahead. Your total stopping distance includes both your reaction time and the actual braking distance, and both increase with speed. So driving at a pace you can stop for any hazards you glimpse ahead gives you the best chance to avoid a collision. This approach matters especially when conditions change. Wet or icy roads, rain, fog, poor lighting, or a heavy vehicle can all lengthen your stopping distance. In those cases, you reduce speed so the visible distance is enough to stop smoothly. The posted speed limit is the maximum you may drive, not a guarantee of safety under every condition, and trying to maintain traffic flow by speeding up can leave you with insufficient stopping distance if a hazard appears.
