The correct answer is: 2 seconds

When driving at 55 MPH, the time it takes for a vehicle in front of you to be seen at night is generally around 2 seconds, mainly due to reaction time and the limitations of visibility in low-light conditions. At this speed, you will cover a significant distance in the time it takes for the headlights to reach another vehicle and for your brain to register its presence. Considering the context of nighttime driving, it’s important to note that visibility is reduced, and thus, drivers need to be more vigilant. Your reaction time contributes to the total time you perceive the vehicle in front of you, which is why recognizing its presence quickly is crucial to maintaining safe following distances and preventing accidents. The other options suggest longer durations, which do not accurately reflect the typical reaction and visibility time at this speed under night driving conditions.
