Emergency vehicle lights are red, blue, or white lights sported by a police vehicle, an ambulance, or a fire truck. When such a vehicle is proceeding in response to an emergency, the lights on it would be continuously blinking. When the emergency vehicle lights are flickering and are accompanied with an active siren, it is the duty of every other vehicle on the road to yield to the emergency vehicles and let them pass at the speed they want.

Emergency vehicle lights may also be used on personal vehicles responding to an emergency situation. Different states have different rules on the colors usable on personal vehicles. A blue flashing light is used in many states by volunteer firefighters, while a green one is used by emergency medical technicians or volunteer ambulance services. Amber is used on vehicles like tow trucks, or snow plows that are involved in hazardous operations. In larger cities amber light could be used on the vehicles of those doing volunteer crime patrol.

Those who use emergency vehicle lights on their personal vehicles must have the authorization from the head of their volunteer organization to use such lights. Other vehicles on the road are not bound to yield to these vehicles. The special lights used on a personal vehicle are known as courtesy lights in that it is a sort of request from those vehicles to the other vehicles on the road to let them go faster. But the other drivers need to do so only at their discretion and they are not bound by rule to give way.

When an ambulance or police vehicle or fire engine with flashing emergency vehicle lights approaches an ordinary vehicle, that vehicle should move to the curb or right hand edge in a way parallel to the road, away from the intersection. For other drivers to give way, it is important that emergency vehicle lights should be flashing. Depending on the angle in which an emergency vehicle is approaching, the color of the light may not be clearly perceivable from other vehicles whereas eyes will clearly record the flashing effect. That is why flashing is a must for emergency vehicle lights

Both the public and the operators of emergency vehicles should be coached well on rgency vehicle lights. This is a must to avoid accidents that could result from the extra speed at which emergency vehicles move. And it is not enough that both parties are familiar with the rules of their own state. They should ideally be familiar with the rules of at least their bordering states because both emergency vehicles and ordinary motorists will have to cross borders now and then.

Besides the rules set by the law, operators can use their own discretion also in using rgency vehicle lights sirens to minimize accidents. All emergency situations are not such that emergency vehicles should move towards the point at breakneck speed. Once the vehicle operators know clearly that reaching the place superfast is not crucial for saving the situation, they can move at the same pace as other vehicles so that there is less inconvenience for other vehicles and less chances of an accident.
