The KT4 knowledge test is a 32-question multiple-choice exam covering Victorian heavy vehicle road rules, the HVNL, Chain of Responsibility, fatigue management (work diaries, standard hours), load restraint, vehicle inspections, and rigid vehicle control. You need 26 out of 32 correct (~81%) to pass. The test must be passed before any practical assessment. Victoria applies a zero BAC limit to all heavy vehicle drivers over 4.5t GVM, and caps all heavy vehicles at 100 km/h regardless of posted limits.

1What is the maximum speed limit for any heavy vehicle anywhere in Victoria?

A.110 km/h

B.100 km/h

C.90 km/h

D.120 km/h

Explanation: In Victoria, it is an offence for any heavy vehicle to travel faster than 100 km/h anywhere in the state. Even where road signs show 110 km/h, heavy vehicles are still capped at 100 km/h under the Heavy Vehicle National Law as applied in Victoria.

2What is the blood alcohol concentration (BAC) limit for a driver of a heavy vehicle greater than 4.5 tonnes GVM in Victoria?

A.0.05%

B.0.02%

C.0.00%

D.0.08%

Explanation: Victoria requires a zero BAC (0.00%) for all drivers of heavy vehicles with a GVM greater than 4.5 tonnes. This is stricter than the 0.05% limit that applies to most car drivers and reflects the increased risks posed by heavy vehicles.

3Under standard hours, what is the maximum work time a solo heavy vehicle driver may perform in any 24-hour period?

A.10 hours

B.12 hours

C.14 hours

D.16 hours

Explanation: Standard hours for a solo heavy vehicle driver permit a maximum of 12 hours of work time in any 24-hour period, with at least 7 continuous hours of stationary rest required in that same period. Work time includes all driving, loading, unloading, and vehicle-related tasks.

4Which of the following best describes the Chain of Responsibility (CoR) under the Heavy Vehicle National Law?

A.Only the driver is legally responsible for road law breaches

B.Responsibility rests with the vehicle owner, not the driver

C.Anyone with control in a transport operation can be held legally liable for breaches

D.Liability applies only to the employer of the driver

Explanation: The Chain of Responsibility means that anybody who has control over a transport operation — including employers, schedulers, loaders, and consignors — can be held legally liable for road law breaches. Control equals responsibility equals legal liability under the HVNL.

5A heavy vehicle has a GVM of more than 12 tonnes. How many portable warning triangles must be carried at all times in Victoria?

A.One

B.Two

C.Three

D.Four

Explanation: Victorian law requires drivers of heavy vehicles with a GVM over 12 tonnes to carry three approved portable warning triangles at all times. If the vehicle or its load stops on or near the road, all three triangles must be deployed as prescribed by the HVNL.

6On a road with a speed limit of 80 km/h or more, at what distance behind a stopped heavy vehicle must the first warning triangle be placed?

A.50-150 metres

B.100-200 metres

C.200-250 metres

D.300-350 metres

Explanation: On roads with a speed limit of 80 km/h or more, one warning triangle must be placed 200-250 metres behind the stopped vehicle or fallen load, one 200-250 metres in front, and one beside the vehicle. This applies when the vehicle is not visible for 300 metres in all directions.

7A heavy vehicle driver must stop their vehicle when signalled to do so. Who is authorised to signal a heavy vehicle to stop in Victoria?

A.Police officers only

B.Police officers and VicRoads Transport Safety Services (TSS) officers

C.Any government employee in uniform

D.Local council rangers and police officers

Explanation: In Victoria, drivers must stop when signalled by either a Police officer or a VicRoads Transport Safety Services (TSS) officer. TSS officers can intercept offending vehicles, enforce HVNL provisions, and direct vehicles to weighbridges. It is an offence not to stop when signalled by either.

8A heavy rigid vehicle with pneumatic tyres is travelling on a road posted at 110 km/h. What is the legal maximum speed for this vehicle?

A.110 km/h

B.105 km/h

C.100 km/h

D.90 km/h

Explanation: In Victoria all heavy vehicles with pneumatic tyres must comply with the posted speed limit AND must not exceed 100 km/h. In a 110 km/h zone the 100 km/h cap therefore applies, making 100 km/h the effective legal maximum for the rigid truck.

9A fatigue-regulated heavy vehicle is defined as a vehicle with a GVM of more than how many tonnes?

A.4.5 tonnes

B.8 tonnes

C.12 tonnes

D.15 tonnes

Explanation: Under the HVNL, a fatigue-regulated heavy vehicle includes trucks with a GVM of more than 12 tonnes. Buses with seating for more than 12 adults are included from 4.5 tonnes. The 12-tonne threshold is the key boundary for mandatory work diary requirements for trucks.

10Under standard hours, a solo heavy vehicle driver must not work more than 5¼ hours without taking at least how much rest?

A.5 continuous minutes

B.15 continuous minutes

C.30 continuous minutes

D.60 continuous minutes

Explanation: Standard hours require that in any 5½-hour period, a solo driver must not work more than 5¼ hours. At least 15 continuous minutes of rest must be taken in that 5½-hour window. This prevents long continuous driving shifts without any break.

VIC Heavy Rigid Knowledge Test Study Tips from Top Performers

1Read the entire Victorian Bus & Truck Drivers' Handbook — every KT4 question comes from its content, including chapters on fatigue, HVNL, load restraint, and vehicle checks

2Memorise the key numbers: 32 questions / 26 to pass, 0.00% BAC, 100 km/h maximum, 12h standard hours work limit, 7h minimum rest, 100 km work diary threshold, and 3 warning triangles for vehicles over 12t GVM

3Focus heavily on Chain of Responsibility — understand that everyone in the supply chain (not just the driver) can be held liable for unsafe heavy vehicle operations

4Understand the standard hours tables: in any 5.5h period, max 5.25h work with 15 min rest; 8h period: max 7.5h with 30 min rest; 24h: max 12h work with 7h stationary rest

5Study load restraint carefully — know the difference between tie-down and friction methods, the 20% vertical restraint requirement, and the rear (3m) and front (1m) overhang limits without a permit

Frequently Asked Questions

How many questions are on the VicRoads KT4 heavy rigid knowledge test?

The KT4 knowledge test consists of 32 multiple-choice questions based on the Victorian Bus & Truck Drivers' Handbook. All questions relate to the legal requirements for driving light rigid (LR), medium rigid (MR), and heavy rigid (HR) vehicles in Victoria. This practice set has 100 questions for thorough preparation.

What score do I need to pass the KT4 knowledge test?

You must correctly answer at least 26 of the 32 questions to pass the KT4, equivalent to approximately 81%. If you fail, you will need to rebook with the accredited provider. Practising all content areas — especially fatigue management, Chain of Responsibility, and load restraint — is critical to achieving this score.

What is the BAC limit for heavy vehicle drivers in Victoria?

Victoria requires a zero blood alcohol concentration (0.00% BAC) for all drivers of heavy vehicles greater than 4.5 tonnes GVM. This is stricter than the 0.05% limit that applies to most car drivers and applies from 1 April as a statewide rule for all such vehicles.

What is the maximum speed for a heavy vehicle in Victoria?

It is an offence for any heavy vehicle in Victoria to travel faster than 100 km/h. This cap applies even where a speed sign shows 110 km/h. In built-up areas without a sign, the default is 50 km/h. In a 40 km/h local traffic zone the 40 km/h limit applies.

Do I need a work diary as a heavy rigid vehicle driver?

A National Driver Work Diary is required if you drive a fatigue-regulated heavy vehicle (over 12 tonnes GVM for trucks) 100 km or more from your home base. If you always drive within a 100 km radius (local work) under standard hours, a work diary is not required by law, but you must still comply with fatigue management limits.

What is the Chain of Responsibility (CoR) and why does it matter for the test?

The Chain of Responsibility (CoR) under the HVNL means that anyone who has control over a transport operation — not just the driver — can be held legally liable for road law breaches. This includes employers, schedulers, loaders, consignors, and receivers. CoR questions appear in the KT4 and test your understanding that control equals responsibility equals legal liability.

What is the difference between the KT4 and KT5 knowledge tests?

The KT4 (32 questions, pass mark 26) covers Light Rigid, Medium Rigid, and Heavy Rigid vehicle requirements and is based on the Victorian Bus & Truck Drivers' Handbook. The KT5 covers Heavy Combination vehicles (prime movers with semi-trailers) and is a 20-question test with a pass mark of 16, based on course-specific materials. You must pass KT4 before attempting the KT5.
