Step-by-step explanation:
The maximum time within which you must deploy your emergency warning devices when stopping on a road or its shoulder is 10 minutes. It is important to quickly warn other drivers of your presence to avoid accidents. Emergency warning devices, such as hazard lights or flares, should be placed a sufficient distance behind your vehicle to give other drivers enough time to react and provide a safe clearance zone. By deploying these devices promptly, you can help ensure the safety of yourself and others on the road. In situations where you are driving and hear the Doppler shift in an ambulance siren, it is crucial to pull over and let the ambulance pass by. This can be important in determining whether you need to stop or yield to emergency vehicles. Paying attention to audio cues like the Doppler shift can help you make informed decisions on the road.
