TS160 is the short name for the Bus Door Safety Systems Technical Specification, a Transport for NSW (TfNSW) standard that sets out exactly how a bus’s passenger doors must detect obstructions, limit closing force, and prevent the bus from moving while a door is open. It came into effect on 1 January 2023 for newly registered NSW buses, replacing the earlier TS155 standard.
If you’ve seen “TS160 door safety system” listed in a bus’s spec sheet, including on our own Yutong D7 page, that’s what it refers to: a door safety system engineered to meet TfNSW’s TS160 requirements, not just a marketing term.
Which Buses Does TS160 Apply To?
TS160 applies to buses in New South Wales that:
- Seat more than 12 people, including the driver
- Operate regular passenger services under the Passenger Transport Act 1990
- Were first registered in NSW on or after 1 January 2023
- Have driver controlled passenger doors
This makes TS160 especially relevant for school bus operators and public and community transport operators running regular routes. Worth noting, the standard specifically excludes tourist, charter, and long distance coach services. Most operators running mixed fleets choose TS160 doors anyway, for consistency and resale value.
What TS160 Actually Requires
TS160 isn’t a single sensor. It’s a specification covering four subsystems that all have to work together:
Door Sensor System
Detects obstructions using test rods that simulate a child’s ankle (35mm) and a wrist (20mm), and must detect obstructions at heights up to 1,500mm above the door step, the height range most likely to catch a young child’s arm or leg.
Closing Force Limits
Doors can’t close with more than 200 Newtons of force if they’re designed to automatically reopen on detecting an obstruction, or 150 Newtons if they aren’t, measured across the last 20 to 300mm before the door fully closes.
Door Brake System
The bus can’t move while a passenger door is open. This is enforced either by engaging the vehicle brakes or locking the driveline, and the system has to be strong enough to hold a fully laden bus stationary on a 12% gradient.
Accelerator Control & Warning System
The accelerator is locked out while doors are open, and the driver gets a visual and audible alert if anything is abnormal, for example a door that hasn’t fully closed.
Door controls only function when the bus is stationary, the system stays active until the doors are fully closed, and there’s an emergency override so the vehicle can still be moved in a genuine emergency. If any part of the system fails, it’s required to default to a safe state rather than fail silently.
How the Yutong D7 Meets TS160
The Yutong D7, VDI Australia’s compact bus that seats 23 to 28 passengers, is built with a door system engineered to comply with TS160 as standard, alongside its 360° Driver Warning Camera System and other advanced safety features. For operators buying under Category 2 school bus funding or running regular NSW passenger services, that means the door system is already engineered to the current standard rather than needing aftermarket modification. It’s also backed by our national service and support network if the system ever needs inspection or servicing.
TS160 vs Earlier Standards
- TS160 replaced TS155, an earlier door safety specification, and sits alongside a family of related TfNSW bus technical specifications covering different safety areas:
- TS142/TS150 (school bus warning signage and lighting)
- TS146 (door safety mechanisms for older vehicle classes)
- TS147 (driver’s field of view of the entrance door)
- TS148 (interior padding on seat backs, handrails and partitions).
- TS160 is the current, most stringent version of the door safety requirement specifically.
Quick Answers
What happens if a bus doesn’t meet TS160?
It can’t be registered for regular passenger service in NSW once the standard applies to it, and operators risk losing accreditation or contracts with agencies such as TfNSW or the Department of Education that require compliant vehicles. TS160 isn’t just a design guideline, it’s enforced at the point of registration and accreditation.
Does TS160 apply outside New South Wales?
Transport for NSW standard, so it’s specific to NSW registered buses. Other states and territories set their own bus safety requirements, though door systems built to TS160 typically meet or exceed most other jurisdictions’ requirements too.
Does a charter or tour bus need to comply with TS160?
Charter and tour services sit outside TS160’s scope, so it isn’t mandatory for those vehicles. What’s easy to miss is that if a bus is later redeployed from charter work onto a regular route, such as a school contract, it will need a TS160 compliant door system before that registration change can go through. That’s why many operators spec it in from the start rather than risk a costly retrofit down the track.
