Participating cities in the "In town without my car!" event (held each 22 September since 1998), present their urban centres in a different light for one day by restricting motorised traffic in certain areas, encouraging the use of sustainable modes of transport and raising awareness for the environmental impacts of citizens modal choice. There were 47 participating cities and towns in Hungary in 2003.
Many of the same cities also conduct events on sustainable mobility as part of the associated week-long European Mobility Week. There were 7 participating cities and towns in Hungary in 2003.
