What must you provide for in winter?

In winter, it is important to ensure safety by preventing slipping hazards. According to German traffic rules, you must keep the steps (such as those on buses or trams) free from snow and ice to avoid accidents when passengers board or alight. Additionally, the floor must remain slip-proof to prevent passengers from slipping inside the vehicle. These measures help maintain safe conditions during the cold season. The side windows not fogging up is important for visibility but is not specifically mandated as a winter safety requirement for passenger areas.
