The best face protection is:

Answer: C — To use the lights of the car ahead of you

The best face protection is to use the lights of the car ahead of you. This is the correct answer because it allows you to see potential hazards on the road more clearly, especially at night or in low-visibility conditions. By using the lights of the car ahead, you can better anticipate any obstacles or changes in the road conditions, helping to ensure your safety while riding. Riding close to the edge of the road (Option A) may increase the risk of debris or obstacles hitting your face, while Option B, keeping your eyes closed, is extremely unsafe and can lead to accidents. Riding without a helmet (Option D) is also dangerous as helmets provide crucial protection in case of a crash.
