Depending on the emergency vehicle itself, there will be many hazard warnings. The lightbar is the visible warning, and the siren on a vehicle is the audible warning. When both of these items are used in conjunction, they act as a powerful notification that the vehicle is hurrying to the scene of an emergency. We see the flashing lightbar units daily out on the streets and it is a reassuring sign that help is on hand for someone in need.

We never like to think of ourselves caught up in any kind of emergency situation that will need police, medical or fire fighters help. Sadly, many of us will find ourselves in such situations at some point in our lives. The first response personnel who come to our aid will be a very welcome sight. The first thing you will hear is the siren, then you will see the flashing lightbar, both of these things urge other motorists out of the way and help keep the road clear for the emergency vehicles to respond quickly.

It's a sad state that some motorists find the sound of sirens and the sight of a flashing lightbar somewhat of an inconvenience. Our roads are so congested and over capacity that without the lightbar and siren to draw attention to them, the emergency vehicles could never get through our traffic. You will probably have noticed publicity about the 'move over' law, which has been introduced in many states. This law has been put in place to assist and protect our emergency response personnel on our roads.

Hefty fines and penalty points on your license are what you will get if you choose to ignore any move over law in your state. Many people on our roads leave too little time to get to wherever they need to be, and not only does that cause accidents, it makes people reluctant to have any time cut from their drive. That is why it is so difficult for emergency response vehicles to get past on our highways and roads. Please, if you do see a flashing lightbar up ahead or one appears in your rear view mirror, think of the personnel who are trying to respond to an emergency.

The lightbar and siren are crucial kit on an emergency response vehicle. Some of the lightbar units are internally fitted and this can be a good option for police vehicles. A bright internal lightbar will illuminate a vehicle or person they have stopped, but the person will not be able to see into the vehicle due to the lightbar. This protects our officers from aimed attack whilst their vehicle is stationary. The lightbar is not just purely for lighting, it warns and informs and without the addition of a lightbar to an emergency vehicle, it is just another vehicle
