The public route microbuses can be small, medium-size, and sometimes big buses, with a higher fare than on ordinary municipally funded buses. They also do not take month subscription tickets. Marshrutkas do not carry pensioners. Depending on the city, persons with disabilities, students, law enforcement workers, and civil servants (pass holders) ride for free. Marshrutkas will not take more free passengers (e.g. disabled) than the strictly limited quantity of one per vehicle, while in ordinary buses, trolleybuses and trams the number is not limited and more categories of people (pensioners, etc.) have the right to ride for free. This is why there are many times more marshrutkas in the city than ordinary buses, trolleybuses and trams altogether. Since municipally funded buses must transport pass holders for free, pass holders prefer using municipal buses to private buses. The lack of marshrutkas' free-ride obligations is because they are classed as "taxis." Ordinary municipal buses, which are usually "full of free riders", are as a result unprofitable and cause economic loss. If a marshrutka charges the same fare as a municipal bus, the marshrutka will profit more, since there is an effective doubling of the profit due to there being one or no free pass riders on board. Marshrutka usually operate faster and with greater frequency than ordinary buses. Stopping marshrutka in the city, at established stops, comes out of practice, being difficult because of the large number of passengers and the high frequency of the stops. In the 1990s when local authorities temporarily lost their ability to finance city bus work, the bus drivers installed tablets with the inscription "Taxomotor" in their bus windows. That meant that every passenger had to pay the fare. Belarus In Minsk, Belarus, the fleet of vehicles is the same as Russia, consisting of Mercedes-Benz Sprinter and Ford Transit. Moldova In Moldova, rutierele run all over the capital and to most large cities in the country. Most rutierele are white and have only the roof vent and front windows for airflow. Rutierele will usually seat around 16 people with space for another 15 to 20 to stand while holding railing.
