Emergency Vehicle Lighting - Purpose

Purpose

Emergency vehicle lighting is generally used to clear the right of way for emergency vehicles, or to warn approaching motorists of potential hazards, such as a vehicle that is stopped or moving slower than the rate of traffic, or a car that has been pulled over. It may also be used to provide specific directions to motorists, such as a command to pull over. Some vehicles incorporate a small arrow board to direct traffic.

The use of emergency beacons is restricted by law in many jurisdictions only for responding to an emergency, initiating a traffic stop, bona fide training exercises, or when a specific hazard exists in the road. Most private security agencies have special permits that allow them to use beacons in specific areas.

Famous quotes containing the word purpose:

    To found a great empire for the sole purpose of raising up a people of customers, may at first sight appear a project fit only for a nation of shopkeepers. It is, however, a project altogether unfit for a nation of shopkeepers, but extremely fit for a nation that is governed by shopkeepers.
    Adam Smith (1723–1790)

    In the present civil war it is quite possible that God’s purpose is something different from the purpose of either party.
    Abraham Lincoln (1809–1865)

    In considering the policy to be adopted for suppressing the insurrection, I have been anxious and careful that the inevitable conflict for this purpose shall not degenerate into a violent and remorseless revolutionary struggle.
    Abraham Lincoln (1809–1865)
