Car For Teens Experiment: Good or Bad?

White and Green: Used by Carabineros on patrol bicycles used in urban and beach settings. Red: Historically used by Carabineros de Chile as their main color for emergency lighting. Blue: Used mainly by Policia de Investigaciones de Chile as their main lighting color on their vehicles. Other agencies and authorities that are permitted to carry blue lights on their service or intervention vehicles include the customs administration, the military police, the service for the removal and destruction of explosive devices, the governors of the provinces, the civil defense service, the security service of the railroad network, Infrabel and utility companies. Blue is used for police, red for ambulances and combination of red and blue for fire trucks. Red/red blue combination is used for ambulances. Civilian Ambulance and most fire units across the country use red and blue lights with State Emergency Service motor vehicles in most states being authorised to use the red and blue light combination (WA SES only fit red and blue lights to Priority One Cliff/Vertical Rescue or Road Crash Rescue vehicles, with all others having red only). New South Wales also allows red and blue to be used by Transport for NSW traffic commanders and traffic response crews designated as emergency vehicles.

Fire-fighting equipment imported from European fire brigades (mainly Germany) also uses blue lighting. From May 2022, in the European Union, by law, new vehicles will have advanced emergency-braking system. Red lighting used to be in use for fire engines, ambulances, Patient Transport Service (PTS) ambulances in Queensland, non WA State Emergency Service motor vehicles before they changed to red and blue. Fire trucks are generally imported from the US, and therefore primarily use red lights although European-style fire trucks with blue lights can sometimes be seen and, more rarely, yellow lights as in Spain. Other, more minor law enforcement vehicles (Military Police, CTI, UNP) generally follow the same scheme. This creates a more level ride and reduces vehicle sway. French law strictly states what kind of blue lights and sirens an emergency vehicle can display, with 2 different categories. All emergency vehicles in Austria use blue emergency lights. Amber or yellow lights are used by roadside breakdown vehicles, railway companies, security patrol vehicles, tow trucks, road construction/repair motor vehicles and most other utility vehicles. Amber lights are used for non-emergency warning on many different vehicles - e.g. road construction vehicles, heavy transports, tow trucks, and municipal services.

Taxis commonly display flashing blue lights as decoration, although some taxi drivers install sirens onto their vehicles in order to get around traffic. Blue is used, along with red, for Police/Peace officers, as well as for snow removal vehicles in Ontario (with Amber for Municipal snow removal and amber and blue for Saskatchewan, Alberta). This is used by all State and Federal Police forces, NT Police, Naval Police, Military Police, Air Force Police and Australian Border Force motor vehicles. Until the early 1990s, these police vehicles were equipped with yellow lights, although today they are equipped with a single red and blue LED lightbar on the roof, and sometimes supplementary red, white, and blue grille lights. Blue lights are reserved for emergency motor vehicles in general, such as police, fire, ambulance, State Emergency Service and traffic commanders. Saskatchewan allows red lights with sirens or red and blue lights with sirens for the Personally Owned Vehicles of firefighters and emergency medical first responders. Municipal patrol/community outreach vehicles tend to also use this color if equipped with lightbars. Some restored and or newer firefighting trucks also carry wig-wag or support lighting equipment in this color. Certainly no businesses have been capable of confronting their encroachment into ever newer sources of business while controlling the search engine landscape.

White lights are used on most newer emergency vehicles, both as an extra color on lightbars and in the form of ‘wig-wag’ headlights. Red is used as a main color during emergency procedures, prisoner transport and other situations that might warrant its usage. White flashing lights can be used as a supplementary color in lightbars, and must face forward. Persons driving an emergency vehicle must be 21, and are restricted by law from eating, drinking, or smoking while operating. Belgian law prohibits red lights facing forward and therefore emergency vehicles normally only use blue lights (red lights are allowed at the rear). Red: Fire Department, Volunteer FD responders in certain Provinces (Manitoba, Prince Edward Island, Saskatchewan); other non-police law enforcement in the provinces of ON and QC and search and rescue vehicles in BC. As in most of the world, utility vehicles usually use flashing yellow/amber lights. Alberta also allows red lights on certain classes of utility vehicles, such as natural gas utilities which may need to disconnect a gas line in an emergency.
