There are several reasons why ambulances might have their lights on but no siren. One reason is to avoid panicking or distressing patients who are in a critical condition or experiencing extreme chest pain. Another is to avoid disturbing the community or drawing unnecessary attention, especially at night when there is less traffic. Ambulances might also refrain from using their sirens to protect vulnerable road users, such as cyclists, children, and animals. In some cases, law enforcement may request a silent approach so as not to warn any suspects of their arrival.

What You'll Learn
To avoid causing distress or discomfort to patients
Ambulance staff have a duty of care to their patients, and this includes avoiding causing them distress or discomfort. Ambulance sirens can be very loud and stressful, and so are sometimes turned off to avoid causing patients further anxiety. This is particularly important when a patient is suffering from extreme chest pain or has a heart condition, as stress could make their condition worse.
In addition, the use of sirens at night can be disruptive to the public, and so ambulance drivers may choose to turn them off to avoid waking people in their homes. This is especially true in non-critical situations.
It is also important to consider the impact of sirens on vulnerable people, such as children or older people, as well as animals. Ambulance drivers may choose to avoid using sirens to prevent causing distress to these groups.
In some cases, ambulance drivers may also turn off their sirens when there is no traffic, as there is no need to alert other vehicles to their presence. This can help to reduce noise pollution and avoid causing unnecessary panic.
Overall, the decision to turn off ambulance sirens is made to balance the need for speed and urgency with the potential distress or discomfort it may cause to patients and the public.

To protect vulnerable road users, including cyclists, children, and wildlife
Ambulance workers may choose to turn off their sirens to protect vulnerable road users, including cyclists, children, and wildlife. This is the second most common reason for turning off sirens, according to the North West Ambulance Service. Ambulances may also turn off their sirens when there is no intense traffic, to avoid causing panic or distress, or when they are responding to an incident with the police, who have requested a silent approach.
The loud noise of sirens can be stressful for some patients, particularly those with heart conditions or those who are already in a critical condition. Turning off the sirens can help to calm patients down and reduce their pain.
In addition, the use of sirens can sometimes be unnecessary or even counterproductive. In some cases, the noise of the siren may not be heard by other drivers, or it may cause them to panic and make erratic driving decisions. Studies have shown that EMS personnel die more often than police or firefighters in traffic collisions, and that rapid EMS response with lights and sirens only makes a significant difference in a few circumstances, such as cardiac arrest. As a result, some agencies are working to decrease the use of sirens and improve patient triage to determine when a siren response is truly necessary.
In certain situations, such as at night or when there is no traffic, ambulance drivers may choose to turn off their sirens to avoid disturbing the community or drawing unnecessary attention. This is especially relevant when the ambulance is not in a life-saving hurry and is simply transporting a patient from one hospital to another.

To avoid alerting a criminal to their arrival
In certain situations, ambulances will refrain from using their sirens to avoid alerting criminals to their arrival. This is particularly relevant at night, when the loud noise of a siren could wake people up and potentially alert a criminal that the police are approaching. In these instances, the ambulance will use lights only to help them move through traffic, without creating a disturbance.
Ambulance staff must make a judgement call on whether to use their sirens or not, and in some cases, they may choose to avoid the siren to prevent panicking a patient who is experiencing extreme chest pain or who is in a critical condition. The use of a siren could cause further stress to a patient, particularly if they have suffered a heart attack or been shot, for example. In these cases, the absence of a siren is to avoid alerting a criminal, but to also ensure the patient remains calm.
The decision to use lights only is also made to avoid bothering old citizens, children, vulnerable passers-by, and animals in the street. Again, this is a judgement call made by the ambulance driver, who must weigh up the need for a quick response with the potential disturbance caused by a siren.
In some cases, an ambulance may be running an errand or transporting a patient non-emergently between hospitals. In these instances, the use of a siren is unnecessary, and the ambulance crew will opt for lights only to move through traffic more easily.

To avoid disturbing the community or drawing unnecessary attention
Ambulance workers may choose to drive with the lights on but no siren to avoid disturbing the community or drawing unnecessary attention. This is especially true at night, when the loud noise of a siren might wake people up in their homes. Ambulance drivers may also choose to only use lights and no siren when they are transporting a patient who is not in a critical condition and they want to avoid stressing them out. For example, a patient experiencing a heart attack might become more worried if the siren is on, which could make their symptoms worse. Ambulance drivers may also choose to only use lights when there is no traffic, to avoid panicking people without a good reason.

To calm patients with injuries that worsen with stress
Ambulance workers may turn off the sirens or avoid using them altogether to calm patients with injuries that worsen with stress. For example, if a patient is experiencing extreme chest pain or a heart attack, the siren may be turned off to avoid stressing them out further. In addition, if a patient is in a critical condition, such as being shot by a gun, the loud sirens and flashing lights may cause them to panic.
The use of sirens is also dependent on the situation and the driver's judgment. For instance, during the night or in low-traffic areas, ambulance drivers may choose to use only lights to avoid disturbing others unnecessarily. This is especially important when considering the impact on young children, older citizens, vulnerable passersby, and animals.
In some cases, ambulance drivers may also turn off the sirens when stuck in heavy traffic or at intersections to avoid causing panic or unnecessary noise disturbance. However, it is important to note that the absence of sirens does not indicate a lack of urgency, and drivers should still pull over or make way for ambulances even when they are not using their sirens.
