• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 20 seconds

Answer: (B)

To safely execute a passing maneuver at a speed of 55 mph, it is essential to consider both the distance required to overtake and how long it will take to do so. At 55 mph, a vehicle travels approximately 80 feet per second. When planning a pass, a driver needs to factor in the time it takes to accelerate past the vehicle being overtaken, re-enter the lane, and ensure there is adequate space between vehicles for a safe merge. Generally, a minimum of 10 seconds is suggested for a safe passing distance and action. This timeframe allows drivers to observe their surroundings, assess the speed of oncoming traffic, and complete the maneuver without rushing, which could lead to accidents. This duration also provides enough time to signal intentions and maintain a safe distance from the vehicle being passed. Considering these factors highlights why 10 seconds is the most appropriate estimate for safely executing a pass at that speed.
