1What is the blood alcohol concentration (BAC) limit for a driver operating a heavy vehicle with a GVM greater than 4.5 tonnes in Tasmania?

A.Zero — no alcohol is permitted

B.0.05 grams per 100 mL of blood

C.0.02 grams per 100 mL of blood

D.0.08 grams per 100 mL of blood

Explanation: Under Tasmanian law, the BAC must be zero when driving any heavy vehicle with a GVM of more than 4.5 tonnes, a public passenger vehicle such as a bus or coach, or a vehicle carrying a dangerous load. This is stricter than the 0.05 limit that applies to most car drivers.

2A heavy vehicle driver in Tasmania has a GVM of more than 12 tonnes. What is the maximum speed they may drive even if the posted speed limit is 110 km/h?

A.110 km/h, the same as the posted limit

B.90 km/h

C.100 km/h

D.80 km/h

Explanation: The Tasmanian Heavy Vehicle Drivers Handbook states that if the posted speed-limit sign shows a number over 100 and the driver is driving a vehicle with a GVM over 12 tonnes (or a bus with GVM over 5 tonnes), the maximum speed applying to that driver is 100 km/h, regardless of the posted limit.

3What is the minimum following distance a heavy vehicle driver should maintain behind another vehicle to provide adequate crash avoidance space?

A.Two seconds

B.Three seconds

C.Four seconds

D.Six seconds

Explanation: The Tasmanian Heavy Vehicle Drivers Handbook specifies that a total of at least four seconds of crash avoidance space is needed for a heavy vehicle driver to react and respond to a situation in front. In poor conditions such as rain, night-time or gravel roads, even more than four seconds may be required.

4Under the Tasmanian Road Rules, what minimum distance must vehicles 7.5 metres or longer keep between themselves and the next long vehicle ahead, on a single-lane highway outside a built-up area?

A.30 metres

B.45 metres

C.60 metres

D.100 metres

Explanation: The Tasmanian Road Rules require all vehicles 7.5 metres or longer to keep at least 60 metres between themselves and the large vehicle in front. This rule does not apply on multi-lane roads, in built-up areas, or when overtaking.

5Under standard fatigue management hours in Tasmania, what is the maximum continuous work time allowed before a heavy vehicle driver must take a rest break?

A.3 hours with no required break

B.5 hours and 30 minutes

C.7 hours and 30 minutes

D.12 hours

Explanation: Under standard fatigue management hours, a solo heavy vehicle driver must take a minimum 15-minute rest break within the first 5 hours and 30 minutes of work after a major rest break. Work includes driving and all other tasks associated with the vehicle.

6Under standard fatigue management hours, what is the maximum total work a solo heavy vehicle driver may perform in any 24-hour period?

A.8 hours

B.10 hours

C.12 hours

D.14 hours

Explanation: The standard fatigue management rules allow a maximum of 12 hours work in any 24-hour period, combined with at least 12 hours rest (including at least 7 hours of continuous rest). Exceeding this limit is a serious offence under the National Heavy Vehicle Law.

7When is a heavy vehicle driver required to use a National Driver Work Diary in Tasmania?

A.Only when driving interstate

B.Whenever driving a fatigue-regulated vehicle of any kind

C.When driving a fatigue-regulated vehicle more than 100 km radius from their base

D.When carrying a load greater than 8.5 tonnes on a single axle

Explanation: A National Driver Work Diary is required when driving a fatigue-regulated heavy vehicle more than 100 km radius from the driver's base. For local work (100 km or less), drivers still need to record work and rest times, but the formal National Diary is only required for the greater-than-100 km distance.

8What is the maximum height of a vehicle and trailer combination (including the load) that may use Tasmanian roads without a permit?

A.4.0 metres

B.4.3 metres

C.4.6 metres

D.5.0 metres

Explanation: The statutory limit for the height of any vehicle or combination (including load) in Tasmania is 4.3 metres. Exceeding this height requires an oversize vehicle permit. The maximum length for a combination is 19 metres and width is 2.5 metres.

9What is the maximum width (excluding exemptions such as mirrors and lights) allowed for a heavy vehicle or combination on Tasmanian roads without a permit?

A.2.0 metres

B.2.5 metres

C.3.0 metres

D.3.5 metres

Explanation: The statutory width limit for any vehicle or combination in Tasmania is 2.5 metres (measured excluding mirrors, lights, reflectors, and anti-skid devices). Exceeding this requires an oversize permit.

10How many portable warning triangles must a heavy vehicle with a GVM exceeding 12 tonnes carry?

A.One

B.Two

C.Three

D.Four

Explanation: A vehicle or combination with a GVM of more than 12 tonnes must carry three portable warning triangles at all times. If the vehicle stops and is not visible for 200 metres in all directions, the driver must place one triangle 50–150 m from the front, one 50–150 m from the rear, and one at the side of the vehicle.

This is stricter than the 0.05 limit for ordinary car drivers. Heavy vehicle learner drivers must also have zero BAC.

What is the maximum speed for a heavy vehicle over 12 tonnes GVM in Tasmania?

100 km/h, even if the posted speed limit is higher (e.g. 110 km/h). In addition, heavy goods vehicles with a GVM over 15 tonnes built after 1 January 1988 must be fitted with a speed limiter set at 100 km/h. Learner heavy vehicle drivers are limited to 90 km/h in 90–100 km/h zones and 100 km/h in 110 km/h zones.

How long is a Tasmania Heavy Vehicle Knowledge Test result valid?

The result is valid for 12 months from the date you passed. If more than 12 months pass before you complete your practical assessment and obtain your licence, you must sit the knowledge test again. There is no limit on the number of times you can sit the test.
