The true statement about speed is option C: You should choose a speed that will allow you to stop within the distance you can see ahead. It is important to choose a speed that allows you to stop safely within your line of sight. This ensures that you have enough time and distance to react to any potential hazards on the road. For example, if you are driving at a high speed and cannot see far enough ahead, it becomes difficult to stop in time if there is a sudden obstacle. By choosing an appropriate speed based on visibility conditions, you can reduce the risk of accidents and ensure a safe driving experience.
