How far from an approaching intersection should you be prepared to stop?

• A. 50 feet
• B. 100 feet
• C. 150 feet
• D. 200 feet

Answer: (B)

When you approach an intersection, you must have enough distance to stop safely if a hazard appears or the light changes. About a hundred feet gives a reliable buffer for perception and reaction plus the braking distance, especially at moderate speeds on dry pavement. If you’re closer than that, you may not have enough time to notice something, decide to stop, and brake before entering the intersection. Too much extra distance, like the longer options, isn’t needed in normal conditions and can disrupt traffic flow, while the shortest distance leaves too little room to stop safely. So, a hundred feet is the practical, safe preparedness distance.
