Final answer:
When riding at night, it is safest to wear reflective clothing and use car headlights; one should not follow other vehicles too closely. Actions like moving towards ambulances should be avoided for safety. Moonlight is unlikely to cause visual impairment in drivers.
Step-by-step explanation:
When you ride at night, the safest practices include: a) Wearing reflective clothing to increase visibility to other road users, b) Keeping headlights on your car to light your path ahead and ensure you are seen by others, and c) Staying alert to your surroundings and not following the vehicle ahead too closely for safety. It is not recommended to always ride in the center portion of the lane as this might not always be the safest position depending on traffic conditions, and you should never follow the vehicle ahead more closely for safety as this can reduce your reaction time and increase your risk of an accident.
In contrast, options such as running toward or alongside an ambulance are dangerous and should be avoided. It is best to stop moving and become stationary until emergency vehicles have passed. In the context of unexpected situations, like a car accident, aspects such as being blinded by the moon are implausible since the moon is not bright enough to cause significant visual impairment to drivers.
