At times when you are on the road, you are bound to see police cars, ambulances or VIPs flashing blinkers and sirens meaning they are in a hurry. Well, they are always in a hurry to reach their point of destination and as a sign of courtesy, private and public vehicles know for a fact that they have to give way or clear the road to let them pass.
That is a common practice that is done anywhere in the world today and for sure, no one wants to get into trouble or be ticketed as an obstruction for refusing to give way. As a rational driver, emergency or not it would be wise to allow them to pass since you never know what could happen and may be held accountable in the end if the emergencies fail to reach their actual point of destination.
As far as having blinkers and sirens is concerned, there are some people who install them without licenses or permits. By doing so, you are placing yourself in a lot of trouble. In most countries, unless you are licensed or authorized to have such things installed on your car, it would be best to keep that thought clear.
These gadgets are normally restricted to the proper people commissioned to do them. It goes in hand with their work. Some use them for status symbol while others just want to feel powerful. They are used for a purpose. Do not install one unless you have the right to have them.
