When should you not follow too closely?

Answer: C — When driving too fast or closely

Not following too closely is crucial primarily when driving too fast or in close proximity to the vehicle in front of you. Maintaining a safe following distance is essential for adequate reaction time; if the vehicle ahead suddenly stops or slows down, being too close can prevent you from reacting in time to avoid a collision. This principle applies in all driving conditions, but it is especially critical when speed increases or when the distance to the vehicle ahead decreases. While it is also advisable to maintain a greater following distance at night or during adverse weather conditions such as heavy rain, the key factor here is the speed and close distance to other vehicles, which directly affects stopping distance and reaction time. In light traffic, while it may seem safer to follow closely, it is still important to prioritize safe driving practices and maintain sufficient distance.
