Yes, you are generally allowed to sit in a priority seat on public transport if it is currently vacant and no one with a clear priority need is standing nearby. In 2026, the global transit etiquette remains consistent: these seats are not reserved exclusively for specific groups but are designated to be the first given up when someone in need boards. This includes the elderly, pregnant women, people with disabilities, or those traveling with small infants. As a "pro-tip," if you choose to sit in a priority seat, you must remain highly observant of your surroundings. It is considered poor form to be distracted by a phone or to sleep in these seats, as you should be ready to stand immediately and offer the spot without being asked. Some regions may have stricter social norms, but generally, as long as you are prepared to move, utilizing the space is acceptable during off-peak hours.
