Arrow Board for Ute and Light Vehicles: Australia Spec and AS 4192 Compliance Guide

A contractor based in Perth asked our team a question that comes up regularly from Australian traffic control operators: “I need an arrow board for ute — what class do I need, and what does the state road authority actually require?”

The question sounds simple. In practice it has three distinct layers: the product class required under AS 4192:2022, the Traffic Management Plan (TMP) approval pathway for the relevant state, and the physical constraints of fitting the correct panel to the specific vehicle. Get any layer wrong and the board either fails a site inspection or physically does not fit the vehicle.

This guide addresses all three layers using publicly available standards and government documents. All state authority sources cited below are freely accessible online.

AS 4192:2022: The Current Australian Standard for Arrow Boards

AS 4192:2022 (Illuminated flashing arrow signs), published by Standards Australia, is the primary technical specification for arrow boards used for temporary diversion of vehicular traffic on Australian roads. It supersedes AS 4192:2006 and is the version state road authorities reference in current TMP frameworks. The standard is listed at store.standards.org.au/product/as-4192-2022.

Important distinction: AS 4852 governs Variable Message Signs (VMS) — electronic text and symbol display boards. It does not govern arrow boards. Specifying AS 4852 compliance for an arrow board procurement is a category error that appears in inquiries regularly. AS 4192 is the correct standard. For VMS compliance requirements, see Arrow Boards: Meeting Government Standards for AS 4852.2.

Three Classes: A, B, and C

AS 4192:2022 specifies three sign sizes. Industry-published specifications from Australian suppliers confirm the following parameters:

Class	Panel Size	Lamps	Road Speed	Typical Vehicle
A	1,260 × 660 mm	13	Up to 80 km/h	Utes, light vehicles, low-speed roads
B	1,500 × 770 mm	15	Up to 100 km/h	Utes, vans, medium-duty trucks, highways
C	2,400 × 1,200 mm	25	High-speed / freeway	Heavy trucks, TMA vehicles only

Key Performance Requirements

AS 4192:2022 mandates the following for vehicle-mounted panels:

• IP protection: Minimum IP45 per the standard; IP65 exceeds the requirement and is strongly recommended for WA dust and QLD wet season conditions
• Automatic dimming: Integrated light sensor for automatic brightness adjustment is mandatory — manual-only brightness control does not satisfy the standard
• Fail-safe operation: Circuitry must prevent unintended mode changes during electrical faults
• Display modes: Arrow left, arrow right, double arrow, caution/wig-wag — all four required
• Flash rate: Consistent flash rate across full operating temperature range

NSW Supplement: RTA FAS/5

In New South Wales, the Roads and Traffic Authority FAS/5 specification adds requirements over the AS 4192 baseline. Class A and B panels used on NSW state roads must hold FAS/5 test approval. When sourcing for NSW projects, request FAS/5 documentation separately from AS 4192 compliance confirmation. These are two different documents.

Class A and B Arrow Boards for Utes and Light Vehicles

Class A Arrow Board: The Standard Ute Solution

Class A is the correct specification for the majority of arrow board for ute applications in Australia. At 1,260 × 660 mm and 13 lamps, it fits within the standard tray width of most half-ton utes without overhanging the vehicle body.

Compatible vehicles: Toyota HiLux, Ford Ranger, Mitsubishi Triton, Isuzu D-Max, Mazda BT-50, Nissan Navara

Mounting options:

• Roof rack or tray frame cross-bar mount: Most common. The panel attaches to a dedicated bracket on the tray frame or roof rack. Confirm the rack’s static load rating — a Class A panel with bracket typically weighs 8–12 kg.
• Cab-top drilled bracket: Used for flagger and pilot vehicle roles without a tray. Limits the practical panel size to Class A.
• Ute tray cage mount: Bolts to the inside of a ute tub or cage — common in council and utility fleet configurations.

For a detailed breakdown of mount types and compatibility across different vehicle configurations, see Choosing the Right Mount for Your Vehicle Mounted Arrow Board.

Power: Class A panels draw approximately 6–9A at 12V. A factory auxiliary power outlet (APO/cigarette lighter circuit) rated at 10A is borderline sufficient for short-duration use. For deployments exceeding 30 minutes, hardwire to a dedicated circuit with a 10A fuse to avoid tripping the factory circuit.

Road speed boundary: Class A covers roads up to 80 km/h. Deploying Class A on a 100 km/h road is non-compliant under AS 4192:2022.

Class B Arrow Board: 100 km/h Roads and Larger Utes

Class B (1,500 × 770 mm, 15 lamps) is required for vehicle-mounted arrow board applications on 100 km/h roads — standard on state highways across WA, QLD, and rural NSW.

Ute fitment note: Panel width at 1,500 mm exceeds the tray width of many single-cab utes. Measure the available tray or roof width before specifying Class B on a half-ton ute. Dual-cab utes with extended trays or aftermarket tray systems typically accommodate Class B without structural concern.

Weight: Class B panels with steel bracket weigh 12–18 kg. Confirm the roof rack or tray frame load rating for the specific vehicle model and bracket combination.

Van mounting: Toyota HiAce, Ford Transit, and Mercedes Sprinter vans accommodate Class B on a roof rack or rear-face bracket. Rear-face mounting is common for pilot vehicle operations in QLD and WA.

Power: Class B draws approximately 10–14A at 12V. Hardwired circuit with dedicated fusing is required — a factory APO outlet cannot sustain this draw safely.

Class C: Not Suitable for Standard Utes or Vans

At 2,400 × 1,200 mm and typically 35–50 kg with bracket, Class C exceeds the physical and load capacity of light vehicle roof rack and tray systems. Class C is designed for heavy trucks and TMA vehicles on freeways and high-volume state highways. Do not specify Class C for ute or van applications. For truck and TMA vehicle arrow board requirements, see the Truck-Mounted Arrow Board: Complete Buyer’s Guide for Fleets and Rental Companies.

State Road Authority Requirements: What Your TMP Must Reference

The product class satisfies the equipment specification. The TMP satisfies the road authority. Both are required for deployment on state-controlled roads. Each state has a current governing document:

New South Wales — TfNSW TCAWS Manual

Transport for NSW published the Traffic Control at Work Sites (TCAWS) Technical Manual Issue 6.1 in February 2022. The manual governs all traffic control device deployment on NSW state roads and references AS 4192 for flashing arrow signs. From 26 August 2025, TfNSW also implemented new Minimum Requirements for Contractor Vehicles, raising compliance benchmarks for all vehicles operating under TfNSW contracts — including light utes used as pilot or flagger vehicles.

Victoria — DTP Code of Practice (December 2023)

The Victorian Department of Transport and Planning updated the Code of Practice for Worksite Safety — Traffic Management on 1 December 2023, incorporating the Austroads Guide to Temporary Traffic Management (AGTTM). DTP began enforcing compliance to the new CoP for all Memorandum of Authorisation (MoA) permit applications from 14 October 2024. Any arrow board for ute deployment on a DTP-managed road in Victoria must be documented in a Traffic Guidance Scheme (TGS) submitted with the MoA permit application.

Western Australia — Main Roads CoP (March 2026, Edition 2.0)

Main Roads WA published Edition 2.0 of the Traffic Management for Works on Roads Code of Practice in March 2026, incorporating AGTTM Part 8 — 2025. WA requires traffic management to be based on the Austroads Guide to Temporary Traffic Management. Arrow board equipment must be specified in the Traffic Management Plan submitted to Main Roads WA for approval.

Official source: mainroads.wa.gov.au

Queensland — TMR MRTS229

Queensland’s Department of Transport and Main Roads publishes MRTS229 — the technical specification for electrical and ITS equipment on state-controlled roads. Arrow boards deployed under TMR contracts must meet MRTS229 requirements. The current version is publicly available at tmr.qld.gov.au.

Six Checks Before Ordering an Arrow Board for Your Ute

Based on procurement inquiries from Australian traffic control operators and equipment hire companies, these are the six verification points that prevent costly post-delivery problems:

1. AS 4192:2022 compliance confirmation. Request written confirmation of the panel class and compliance with AS 4192:2022. For NSW state roads, also request FAS/5 test approval documentation.
2. Class against posted speed limit. Class A for up to 80 km/h; Class B for up to 100 km/h. Confirm the posted speed at the deployment site before specifying the class.
3. IP rating. AS 4192 requires minimum IP45. IP65 is recommended for WA and QLD conditions — dust ingress and heavy rain are standard hazards.
4. Mounting bracket compatibility. Specify the bracket type (roof rack cross-bar, tray frame, cab-top) and confirm the static load rating for the vehicle model. Request the wind load specification for highway-speed deployments — dynamic load at 100 km/h exceeds the static figure.
5. Power draw vs vehicle circuit. Class A: 10A APO borderline for short use, dedicated circuit preferred. Class B: hardwired dedicated circuit with fusing required. Confirm the controller operates on 12V DC.
6. Automatic dimming. AS 4192:2022 mandates automatic brightness adjustment via integrated light sensor. Manual-only brightness control does not satisfy the standard. Request written confirmation of auto-dimming capability.

These checks apply across the traffic safety equipment hire and contracting sector in Australia.
