What is the minimum distance you should be scanning ahead in urban areas?

• A. 8 seconds
• B. 12 seconds
• C. 4 seconds
• D. 20 seconds

Answer: (B)

In urban driving you need to scan far enough ahead to spot hazards early and have time to react. Scanning about 12 seconds ahead gives you a window to see pedestrians stepping into crosswalks, vehicles braking suddenly, doors opening from parked cars, and traffic signals changing, so you can slow, stop, or change lanes smoothly before you reach the danger. At typical city speeds, 12 seconds translates to several hundred metres of visibility, which is enough to handle the unpredictability of urban traffic. If you only scan 8 seconds or 4 seconds, you’re closer to hazards and may have to brake hard or swerve at the last moment. Scanning 20 seconds ahead in city traffic isn’t practical; you’d be looking so far ahead that you could miss closer hazards and late signals. Adapt your scan to conditions, but the minimum in urban areas is 12 seconds.
