Tasmania school buses: size bands, bus age and seatbelts

Tasmania

Tasmania school buses: size bands, bus age and seatbelts

Tasmania runs 349 school services through 106 contracted operators, and the operators own the buses. Two things here will surprise anybody arriving from New South Wales: seatbelts are required only on small buses, and the contract sets five formal size bands that bind what an operator may run and what they may replace it with.

Where this comes from. Drawn from the Passenger Transport Contract Standard Conditions, the Vehicle and Traffic (Vehicle Standards) Regulations 2024 and the Passenger Transport Services Regulations 2023. Where a provision was reached through a law library rather than the authorised text, the substance is given and the instrument cited rather than quoted. Check the authorised version before relying on exact wording.

Who runs it

Requirement	What it says	Source
The department changed its name	On 2 July 2026 the Department of State Growth was renamed Building Tasmania. Contract contacts are now at building.tas.gov.au, but legacy State Growth branding and email addresses still appear on live government pages and in archived tenders. Expect both.	tas.gov.au machinery of government
The contracting body	Building Tasmania, through its Passenger Transport Branch. The contracting counterparty in the documents is the Crown.	Transport Services
The education department is not involved	The Department for Education, Children and Young People has no contracting, funding or specification role. It refers bus matters out. If you are selling a bus into Tasmania, the conversation is with Building Tasmania.	DECYP
Scale	106 contracted operators running 349 school services — a fragmented base of mostly small family businesses, many with one or a few buses, each needing individual Crown approval for a vehicle change.	Transport Services
Contract term	Five plus five years, running to the end of the 2029 school year.	Transport Services

The five size bands

Requirement	What it says	Source
Small Bus	At least 18 and at most 25 adult passenger seats.	PSC Standard Conditions
Medium Bus	At least 26 and at most 35.	PSC Standard Conditions
Large Bus	At least 36 and at most 49.	PSC Standard Conditions
Extra Large Bus	A rigid bus with at least 50.	PSC Standard Conditions
Articulated Bus	Two rigid sections on a pivoting joint with bellows, at least 60 seats.	PSC Standard Conditions
How the band is read	From the adult passenger seating capacity on the compliance plate, or a later modification plate. The operator may not change that capacity without the Crown’s prior written consent — a seat-count change is a contractual act, not a workshop job.	cl. 1.8(b)–(c)
How it binds	Where the service table specifies a bus size, the operator may only use a vehicle equal to or greater than it, and must match any specified seating configuration and minimum operational capacity. A replacement must normally be the same size as the bus it replaces unless the Crown directs otherwise because passenger numbers have changed.	cl. 9.3, 10.3(f)

Seatbelts — the opposite of what you would assume

Requirement	What it says	Source
The rule	Seatbelts are required only on Small Buses, where lap-sash belts must be fitted for all passengers. There is no seatbelt requirement for a Medium, Large, Extra Large or Articulated school bus. That single clause is the only mention of seatbelts in the whole 107-page contract.	cl. 9.4(b)
The reasoning	The government’s own safety booklet says most school bus seats are unsuitable for belts, and that lap belts on low seatbacks can increase head and neck injury risk. Large buses rely instead on closely spaced energy-absorbing seatbacks, stronger bodies, a higher seating position and greater mass.	School Bus Safety Booklet 2023
Three-for-two seating	Permitted, counting three children as two passengers, but only where none of them has turned 10 and the seats either have no belts or have belts designed specifically to convert two adult positions into three child positions. The age limit was lowered from 12 to 10 in June 2023, so an older source saying under 12 is out of date.	PTS Regs 2023 Sch 1 cl. 2
Standing passengers	Permitted on a prescribed vehicle: at least 1.8 m floor to roof wherever someone may stand, an aisle at least 380 mm wide, and a holding device for each standing passenger. Capacity is the number of holding devices, capped at one person per 1,600 cm² of unobstructed floor. A vehicle that is not a prescribed vehicle has a standing capacity of zero. Operational capacity must be displayed inside the bus.	PTS Regs 2023 Sch 1 cl. 3; reg 15(2)
What this means for a bus	A Tasmanian school bus is specified for unbelted seating, three-for-two child seating and standing passengers. A belted bus optimised for New South Wales is a different product.

Bus age — two separate tests

Requirement	What it says	Source
Maximum age in service	A Small Bus may run to 15 years. A Medium, Large, Extra Large or Articulated bus on a school service may run to 30. On a general access service the limit is 21.	cl. 9.4(d)
Maximum age entering a contract	Different, and tighter. The Crown may refuse to approve a bus for a school service over 10 years for a Small Bus, over 20 for a Medium, Large or Extra Large, or over 25 for an Articulated. For a general access service the bar is two years — effectively a new bus.	cl. 10.3(b)–(c)
The age clock can reset	Bus Age normally runs from the year of manufacture. But where a bus is not more than two years old when it becomes an Approved Vehicle and has never been used commercially by anyone, its age is counted from the year it entered the contract instead. A genuinely new bus is therefore worth up to two extra years of contract life.	PSC definitions
Where the year comes from	The year on the body compliance plate or identification plate, or where there is none, from the vehicle identification number.	PSC definitions
Replacement	Breaching the in-service age ceiling makes a vehicle automatically cease to be an Approved Vehicle, which triggers a mandatory replacement obligation. The same applies if the bus is lost, stolen, destroyed or damaged beyond economic repair.	cl. 10.6, 10.7
Approval takes time	Every change of Approved Vehicle needs the Crown’s prior written approval. The Crown must answer a replacement application within fifteen business days.	cl. 10.1–10.3

School bus signs and lights

Requirement	What it says	Source
The instrument	Part 8 Division 19 of the Vehicle and Traffic (Vehicle Standards) Regulations 2024, regulations 98 to 101. Tasmania has no TS-style numbering.	SR 2024-015
When it applies	Two warning lights and a sign front and rear, unless the bus operates wholly within an urban area listed in Schedule 1, or is carrying children on a school charter or excursion, or is a regular passenger service not provided primarily to carry children to or from school. The trigger is the urban area exemption, not a weight threshold as in South Australia.	reg 98
The front sign	One of three: the AS 1743 40 km/h speed-limit roundel, image R4-1(40); or the word SCHOOL or the words SCHOOL BUS in capitals at least 100 mm high; or, on an electronic destination sign, those words at the same height shown while the warning lights are flashing. That last option is a genuine specification choice worth knowing about.	reg 101(2)
The rear sign	Both the 40 km/h roundel and the words WHEN LIGHTS FLASH.	reg 101(3)
The roundel	Square or rectangular, in AS 1743 R4-1(40) proportions, with the red circle at least 200 mm in diameter on the front and at least 440 mm on the rear, in class 1 or 2 retroreflective material to AS 1906:2007.	reg 101(4)
The legend	Sixty-millimetre black lettering in series D characters to AS 1744-1975 on white. Either two separate signs each 450 by 70 mm, or one 900 by 70 mm. Alternatives exist for a single stacked sign, and for a bus at or under 6,000 kg GVM, three stacked signs each at least 300 by 70 mm.	reg 101(5)–(6)
The lights	Flashing yellow, 90 to 180 times a minute, the pair at each end alternating, with an effective lit lens area of at least 60 cm² and a specified candela pattern peaking at 1,500 cd, measured by the third edition ADR 6 test method. Automatic on door opening and for 10 to 20 seconds after all doors close unless the driver switches them off, with a visible or audible indicator and an off switch.	regs 99–100
State law overrides the ADR here	Regulation 99 applies to a bus despite any requirement of a third edition ADR.	reg 99(6)
Passing speed	Forty km/h within 50 m of a bus displaying the sign or lights — against 25 km/h in South Australia.	Transport Services

Other things the contract requires of the bus

Requirement	What it says	Source
A clear panel on the back	At least 1,200 mm wide by 500 mm high must be left free on the external rear surface for the Crown’s road safety and school safety advertising. The Crown pays installation and removal and no fee is payable to the operator. That panel has to coexist with a 440 mm roundel, a 900 by 70 mm legend and two rear warning lights, which is a real constraint on rear body design.	cl. 9.8
Cameras	Not fitted by default. The Crown may direct monitoring equipment be installed, and doing so counts as a directed service variation, so it is paid for. Once video recording is fitted, the contract is prescriptive: interior footage of passengers boarding and alighting and of any payment to the driver, with date and time, retrievable per trip, retained 45 days, supplied on at least five business days’ notice, and exportable through software that automatically blurs faces.	cl. 9.5, 20
Accessibility	The Crown may refuse to approve a vehicle that does not comply with the Disability Standards for Accessible Public Transport 2002 unless an exemption applies. It is a discretionary refusal ground at the point a bus enters the contract rather than an absolute fitment mandate.	cl. 10.3(d)
Emissions	None. The word does not appear anywhere in the 107-page contract, and we found nothing extending the government’s own fleet emissions policy to contracted buses.
Cleaning and advertising	Cleaned regularly and at least weekly. Operator advertising must not obscure route, destination or Crown network branding, and the Crown can require removal at the operator’s cost.	cl. 9.6–9.7
Performance tolerance	School services run on a tighter demerit threshold than general access services — ten points against fifteen to thirty.	cl. 1.10(a), 14.3

Is there a Tasmanian equivalent of BP4?

Requirement	What it says	Source
No	Tasmania publishes no vehicle construction or specification document at all. We checked the full index of industry and operator documents and the student travel policies index.
Where the requirements live	In four places that are nowhere consolidated: the Passenger Transport Contract Standard Conditions for seatbelts, bus age, bus size, monitoring equipment and the rear panel; the Vehicle and Traffic (Vehicle Standards) Regulations 2024 Part 8 Division 19 for signs and lights; the Passenger Transport Services Regulations 2023 Schedule 1 for capacity, three-for-two and standing; and the ADRs through the contract’s requirement to comply with all applicable laws.
What is not a specification	The School Bus Safety Booklet is guidance for parents. It is useful for understanding why the rules are as they are, but it is not a technical requirement and should not be cited as one.

Where ZBus stands

Our three sizes land in three different Tasmanian bands.

The H12 at 57 seats is an Extra Large Bus, the L8 Hybrid at 29 is a Medium, and the L7 Diesel reaches into the Small Bus band at its upper seat count. Only the Small Bus needs seatbelts. And because a bus that is two years old or less and has never been used commercially has its contract age counted from the year it enters the contract rather than the year it was built, selling new rather than low-hour used is worth up to two extra years of contract life to a Tasmanian operator.

What our L7 Diesel does meet

At its upper seat count the L7 Diesel reaches the Small Bus band of 18 to 25 seats
The L8 Hybrid at 29 seats sits in the Medium Bus band of 26 to 35
The H12 at 57 seats is an Extra Large Bus, which needs at least 50 and is rigid
All three are new, so the age clock would run from the year they entered the contract rather than the year of build

What would need checking before a Tasmanian bid

Lap-sash belts for all passengers, which a Small Bus must have and the larger sizes need not
Whether the seat count on the compliance plate puts a given build in the band the service calls for
The 1,200 by 500 mm clear panel on the rear, alongside the roundel, legend and warning lights
Schedule 1 of the vehicle standards regulations, which lists the urban areas where signs and lights are not required — we could not retrieve it
The contract payment model, which sets the capital allowance by bus size and which is not public

If you are replacing a bus under this category, ring 0477 957 513 or email sales@zbus.com.au and we will tell you straight whether we can help. If we are not the right answer, we will say so.
