filters to address and prevent interference among AM stations, with few significant problems". Low-power FM stations In 2000 the FCC began authorizing non-commercial Low Power FM (LPFM) stations, which are not formally a part of the TIS/HAR service, although in a few cases stations have been adapted to serve a similar function. LPFM stations operate with up to 100 watts and generally have somewhat larger service areas than TIS stations on the AM band, and also avoid the increased nighttime interference from distant stations which affects AM band stations. However, in contrast to the TIS service, there are only limited "filing window" periods to apply for permission to build an LPFM station, and these stations are required to produce up to 8 hours of new programming each day, and also in certain instances to share airtime with other licensees. LPFM examples include WTUS-LP in Tuscaloosa, Alabama, originally operated by the Tuscaloosa Tourism and Sports Commission before being transferred in 2016 to the Tuscaloosa City Board of Education, and WGEO-LP in Georgetown, South Carolina, which is operated by the Georgetown City Fire Department. State and local governments may also create state-wide networks to provide non-commercial public safety information via radio using LPFM stations. Colorado has a statewide network of LPFMs used in this manner, while many other state, county, or local governments use one or more stations. Europe In France information is provided at 107.7 MHz FM along selected autoroutes. In Italy most highways are covered by RAI's Isoradio network, broadcasting in most areas on 103.3 MHz. In Germany and the former Yugoslavia, highways and motorways are provided with traffic information by radio, although the original systems have been largely replaced. Newer RDS-based systems interrupt a station's regular programming to give travelers current information about the highway, updated traffic and weather reports, public service announcements by various governmental and public organizations, railway information and news bulletins. These radio systems are most commonly used in Slovenia, Croatia and partly in Serbia. Highways served with traffic radio information include: European route E61: Villach–Kranj–Ljubljana European route E70: Ljubljana–Zagreb–Sisak–Slavonski Brod–Belgrade. Japan In Japan Highway Radio broadcasts on 1620 and 1629 kHz AM along stretches of major expressways. Canada TIS stations operate in Canada (on both AM and FM bands). Brazil TIS stations in Brazil are known as Radiovias ou Rádio-estradas. Currently, Brazil has only a single TIS station in operation, called CCR FM. The radio
