In South Yorkshire residents are also entitled to free travel from 09.00 on weekdays and all day at weekends and Bank Holidays on the following services:

• Any bus or tram within South Yorkshire
• Between stations on the South Yorkshire rail network
• To and from West Yorkshire on Northern Rail services (without changing trains in West Yorkshire)
• Into South Yorkshire by bus from neighbouring areas.

East Riding of Yorkshire

You can use your pass between 09:30 and 23:00 Monday to Friday and at all times on Saturdays, Sundays and Bank Holidays. Please be aware that these time conditions also apply within the East Riding. If you wish to travel within the East Riding before 09:30 or after 23:00 you must purchase the Early Bird Bus Pass.

West Yorkshire

As a West Yorkshire resident, you are also entitled to train travel within West Yorkshire for just 35p after 9.30am, Monday to Friday, and all day at weekends and public holidays. Before 9.30am, bus and rail travel is at full fare.

North Yorkshire

The National pass provides free travel across England from 9.30am until 11.00pm on weekdays, and all day on weekends and on bank holidays. Passes issued by North Yorkshire District Councils and City of York Council will also be valid at all times except between 6.00am and 9.00am Monday to Friday for journeys starting within North Yorkshire and City of York only. Local extensions to the national minimum standard, such as longer times when the pass is valid, will not be available when travelling in other areas. This is also likely to apply to other local scheme enhancements. For example, disabled people who are entitled to travel with a free fare companion may not be able to do so on journeys starting outside North Yorkshire or York. In other areas, only the passholder will be able to travel free.
