Final answer:
The statement that a driver should pull to the right-hand edge of the road and stop for an approaching authorized vehicle with sirens and flashing lights is TRUE. The actual frequency of an ambulance siren matches what you hear when it is directly in front of you. Actions like running toward or alongside an ambulance are incorrect and dangerous.
Step-by-step explanation:
When an authorized vehicle using its sirens and flashing lights approaches a vehicle, the correct action for the driver is to pull to the right-hand edge of the road and stop, waiting for the emergency vehicle to pass. The statement is TRUE. If you are in a situation where an ambulance is driving by with its siren blaring, the Doppler shift will inform you about its relative position to you. The frequency you observe most closely matches the actual frequency of the siren when it is directly in front of you.
The concept of reacting to authority, such as pulling over for emergency vehicles, is an important aspect of road safety. Respecting the authority of emergency responders allows them to perform their duties effectively and reach their destinations quickly, which could potentially save lives.
In contrast, the idea of running toward or alongside an ambulance is incorrect, as it could be dangerous and would not facilitate the emergency response.
