If the speed limit is 55 mph but traffic is moving at 35 mph, what is the safest speed for you to travel?

• A. 35 mph
• B. 50 mph
• C. 55 mph
• D. 25 mph

Answer: (A)

When other vehicles are moving slower than the posted limit, the safest approach is to match the flow of traffic. If the speed limit is 55 mph but surrounding traffic is about 35 mph, driving with them around 35 mph keeps your speed consistent with what’s happening on the road, reducing the risk of rear-end collisions and the need for abrupt braking or risky lane changes. Going up to the full limit would create a large speed difference with the vehicles ahead, making it harder to react to sudden changes. Driving much slower than the traffic can also cause hazards for others. So the best choice is to travel at about 35 mph, the pace of the traffic.
