Answer options
AWhen you pass a fixed object beside the road, count the seconds until the vehicle ahead reaches that object.
BWhen the vehicle ahead passes a fixed object beside the road, time how long you take to reach it with your phone's stopwatch.
CWhen the vehicle ahead passes a fixed object beside the road, count the seconds until you reach that object. Correct

Choose a landmark such as a sign or pole, begin counting as the vehicle in front passes it, and stop counting when you get there yourself; that number of seconds is your following distance. Timing it with a handheld phone while driving is a dangerous distraction.
