Final answer:
Using emergency lights and sirens while transporting a patient to the hospital is a potential risk due to the increased risk of a vehicular crash.
Step-by-step explanation:
Using emergency lights and sirens while transporting a patient to the hospital is considered a potential risk because it increases the risk of a vehicular crash. Answer choice C is the correct option. When an ambulance runs its lights and sirens, it is allowed to go through red lights and exceed speed limits, which can increase the chances of an accident. The safety of both the ambulance crew and the patient is compromised when emergency lights and sirens are used.
