Currently there are emergency vehicles for these countries:
Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Hungary, Italy, Lithuania, Luxembourg, Netherlands, Norway, Poland, Romania, Russia, Slovakia, Sweden and United Kingdom

All vehicles are active in road events, and have working emergency lights - most of them have custom LED lightbars and additional lights. Mod allows accidents scenes for countries that didn't have ambulances, and allows customs road events for France.

Mod disables these vehicles from traffic:
- German and Luxembourg police car VW Passat CC disabled from traffic.
- Hungarian and Russian police car Ford Focus disabled from traffic.

Update:
New vehicles:

AUSTRIA
- Police car VW Transporter T6

ITALY
- Highway police Skoda Superb Combi /Polizia Stradale/
- Carabinieri Jeep Renegade

LITHUANIA
- Police car Seat Leon ST

NETHERLANDS
- Police car VW Transporter T6

POLAND

SPAIN
- National police Peugeot 2008 /Policía Nacional/
- Roads policing unit Renault Talisman /Guardia Civil Tráfico/

Changes and fixes:
- Fixed LOD model for Belgium's police Audi A3.
- Changed lightbars for Czech and Hungarian ambulances - both now feature combo of red and blue light as they should.
- Edited lightbars for other ambulances based on VW Crafter - turned main lightbar to LED one.
- Italian state police cars /Alfa Romeo Giulietta and Fiat Panda/ are now limited to Italian cities only, as they do not roam highways irl, and country roads are under control of Carabinieri. 
Highway police may still spawn outside of highways as there is no way to limit them to highways only in the game.
