Priority vehicles, especially white or blue police cars, are not always the most conspicuous, which can have negative consequences in traffic. Especially in situations such as accident scene insurance, it is very important to be able to see and identify police and other emergency vehicles from a distance and in all weather situations, as this can reduce the likelihood of an encounter and thus protect the lives of police officers, paramedics, firefighters and also ordinary people involved in a potential roadside or roadside incident.   In addition, conspicuous vehicles, again especially police vehicles, are a good aid to traffic calming: the longer they are seen, the greater their impact. Unmarked vehicles are still available for covert action; those that are marked are marked for a purpose and so it would make sense to make them more visible.   Already in 1998, a special group of the British police produced a study on changing the markings of police vehicles on motorways. They recommended the use of retro-reflective markings in yellow and blue, alternating in a checkerboard pattern. Today, the vast majority of police, ambulances and fire engines in the UK use the style recommended at the time, while other countries such as Ireland, Sweden and New Zealand have also adopted this style, and pilot deployment projects are underway in the United States.   The style is called Battenburg and the vehicles look like this: http://media.il.edmunds-media.com/vauxhall/ns/vauxhall_oth_ns_6_717.jp... http://reklamtips.se/media/polisbil1.jpg http://upload.wikimedia.org/wikipedia/commons/d/de/East_of_England_Eme... http://www.police.govt.nz/images/photos/new_livery_elbow.jpg http://fire-engine-photos.com.s3.amazonaws.com/4425.jpg A British study has developed a style of signage that allows the following: - increases the safety of police officers and the public by reducing the likelihood of road accidents, where the visibility of the police vehicle is a factor - police vehicles are visible from 500 m away in normal daylight - allows public and visible policing, giving the public a higher sense of security and also works better in preventive traffic calming - uses the latest materials and is no more expensive than other signage in use before the introduction of this style A summary of the study can be found at http://scienceandresearch.homeoffice.gov.uk/hosdb/publications/road-po... and includes some details of the British solution.   Not only are these types of markings safer, they are also very pleasing to look at (at least to me) and I therefore suggest that the possibility of gradually introducing similar high visibility markings for all types of vehicles in Slovenia should also be explored, with priority for newly purchased vehicles at least.
