When driving, it's important to maintain a safe following distance to allow for enough time to react and stop in case of an emergency. Keeping a distance of at least 4 seconds is recommended when driving at speeds under 40 mph. This allows for enough space and time to stop in case the car in front of you suddenly brakes or an obstacle appears on the road. Options A, B, and C are all incorrect as they do not provide enough space and time for safe stopping. A following distance of 5 seconds may be appropriate for speeds over 40 mph, while 3 and 6 seconds may be too short or too long of a distance, respectively. Therefore, the correct answer of 4 seconds is the best option for safe driving at speeds under 40 mph.
