ALL QUESTIONS TOGETHER.
1. What is the minimum Gross Vehicle Weight (GVW) that requires weighing on Tanzanian public roads?
A. 2,000Kg B. 3,000Kg C. 3,500Kg D. 4,000Kg
Answer: C. 3,500Kg
Rationale: In Tanzania, the legal minimum GVW that subjects a vehicle to
mandatory weighing at a weighbridge is 3,500Kg. This threshold is set to ensure
that vehicles with significant potential to damage road infrastructure are
monitored. Lighter vehicles typically do not pose the same risk, hence are
exempt.
2. Which authority is responsible for overseeing trunk and regional roads in Tanzania?
A. LATRA B. TANROADS C. TRA D. TBS
Answer: B. TANROADS
Rationale: TANROADS (Tanzania National Roads Agency) is the statutory body mandated to manage, maintain, and regulate all trunk and regional roads across the country. LATRA handles transport services, TRA handles taxes, and TBS is focused on standards—not roads.
3. What is the main purpose of a weighbridge?
A. To collect toll fees B. To regulate traffic C. To prevent road damage D. To issue driving licenses
Answer: C. To prevent road damage
Rationale: The core objective of a weighbridge is to ensure that
vehicles do not exceed permitted weight limits, which could lead to excessive
road wear and damage. This control helps preserve the road infrastructure and
promote road safety.
4. Which of the following best describes ‘Axle Load’?
A. Total weight of the vehicle B. Weight of the vehicle’s engine C. Weight transmitted through each axle D. Load in the trunk of the vehicle
Answer: C. Weight transmitted through each axle
Rationale: Axle load refers to the amount of weight carried by a single axle or group of axles. It's a crucial measurement in road safety and maintenance, as excess axle load contributes significantly to road deterioration.
5. When a vehicle is found to be overloaded, what must be imposed immediately?
A. Traffic fine B. Road damage fee C. Insurance penalty D. Arrest of the driver
Answer: B. Road damage fee
Rationale: In line with Tanzanian regulations, an overloaded vehicle is
typically subject to a road damage fee. This fee is meant to compensate for
potential damage caused by the excessive load and deter future violations.
.6. Which of the following departments does a Weighbridge Officer II report to?
A. Legal B. Engineering C. Transport D. Operations
Answer: D. Operations
Rationale:
Weighbridge Officers report to the Operations Department because their primary
duties involve operational oversight of vehicle weighing, record-keeping, and
enforcement of axle load regulations on a daily basis.
7. Which legislation gives TANROADS authority to control vehicle weights?
A. Road Act B. Motor Vehicle Act C. Penal Code D. Transport Safety Act
Answer: A. Road Act
Rationale: The Road Act legally empowers TANROADS to regulate vehicle
weight on trunk and regional roads. This includes overseeing weighbridge
operations and ensuring road infrastructure is protected from overloaded
vehicles.
8. A Special Permit is needed for:
A. Public buses B. Vehicles with abnormal load C. Personal cars D. Motorcycles
Answer: B. Vehicles with abnormal load
Rationale: A special permit is required when transporting abnormal loads
that exceed legal size or weight limits. This permit authorizes legal movement
under specified conditions to prevent road damage and ensure public safety.
9. A weighbridge officer is required to supervise weighing of vehicles during:
A. Off-peak hours B. Emergency times only C. Shifts D. Daytime only
Answer: C. Shifts
Rationale: Weighbridge operations run continuously in shifts to ensure
24/7 enforcement of vehicle compliance. Officers are assigned specific shifts
to maintain consistent and efficient service coverage.
10. One of the key responsibilities of a weighbridge officer is:
A. Training new drivers B. Measuring fuel consumption C. Evaluating scale reliability D. Designing roads
Answer: C. Evaluating scale reliability
Rationale: Weighbridge officers must ensure that the scales are accurate
and functioning properly. This responsibility is vital because any error in
scale readings can lead to incorrect enforcement and legal issues.
11. In case a weighbridge scale malfunctions, a weighbridge officer should:
A. Ignore the error B. Continue using it C. Report the issue immediately D. Shut down the station
Answer: C. Report the issue immediately
Rationale: The correct action is to report the malfunction immediately
to supervisors or technical personnel to prevent incorrect weighing and
potential legal or operational consequences.
12. What does GVW stand for?
A. General Vehicle Weight B. Gross Vehicle Weight C. Guaranteed Vehicle Weight D. Group Vehicle Weight
Answer: B. Gross Vehicle Weight
Rationale: GVW refers to the total weight of a vehicle, including its chassis, body, engine, fuel, driver, passengers, and cargo. It is the primary measurement used to determine compliance with road weight limits.
13. A tandem axle load consists of:
A. One axle B. Two axles C. Three axles D. Four axles
Answer: B. Two axles
Rationale: A tandem axle configuration includes two axles placed closely
together to share the load. This setup helps distribute weight more evenly and
reduces the stress on road surfaces.
14. What tool is primarily used to measure vehicle weight at a weighbridge?
A. Speedometer B. Weighing scale C. Thermometer D. Barometer
Answer: B. Weighing scale
Rationale: A weighing scale, either mechanical or electronic, is the
standard tool used to measure a vehicle’s weight accurately at a weighbridge
station.
15. Which software is commonly used by weighbridge officers to generate reports?
A. AutoCAD B. SPSS C. Excel D. Photoshop
Answer: C. Excel

versatility in organizing, calculating, and analyzing weighbridge data for
daily, weekly, or monthly reports.
16. A weighbridge officer must have skills in:

Answer: C. Record keeping
Rationale: Effective record keeping is crucial for documenting every

traceability, and accountability in weighbridge operations.
17. In case of non-compliance with vehicle dimension limits, the officer should:
A. Confiscate the vehicle B. Call the police C. Instruct transporter to get special permit D. Ignore it
Answer: C. Instruct transporter to get special permit
Rationale: If a vehicle exceeds the legal dimensions without a permit,
the officer must inform the transporter to obtain the required permit before
proceeding, as moving without it is illegal.
18. The term 'Abnormal Load' refers to:
A. Loads under 500Kg B. Standard cargo C. Loads exceeding legal size or weight limits D. Passenger loads
Answer: C. Loads exceeding legal size or weight limits
Rationale: An abnormal load is any cargo that exceeds legally prescribed
size or weight limits. These loads require special permits and often escort
services to ensure safety.
19. The maximum GVW limit for most roads in Tanzania is:
A. 25,000Kg B. 30,000Kg C. 40,000Kg D. 56,000Kg

Rationale: According to Tanzanian road regulations, the general upper
limit for Gross Vehicle Weight on most trunk roads is 56,000Kg. Vehicles
exceeding this limit require special authorization.
20. What is the penalty for overloading a vehicle?
A. Verbal warning B. Traffic court trial C. Road damage fee D. Driver’s license suspension
Answer: C. Road damage fee

responsible for overseeing transport safety, including passenger services,
freight regulation, and fare control.
24. What does an axle represent in vehicle terms?
A. Steering system B. Weight distribution C. Connecting rod between wheels D. Fuel tank
Answer: C. Connecting rod between wheels
Rationale: An axle is a key mechanical component that links the wheels
and supports the weight of the vehicle, facilitating movement and load
distribution.
25. Road damage caused by overloading results in:
A. Better traction B. Smoother roads C. Shorter Road lifespan D. Lower maintenance cost
Answer: C. Shorter Road lifespan
Rationale: Overloaded vehicles apply excessive pressure on road
surfaces, leading to cracks, ruts, and potholes, ultimately shortening the
road's functional lifespan and increasing maintenance costs.
26. Who issues abnormal load permits in Tanzania?
A. Police B. LATRA C. TANROADS D. TBS
Answer: C. TANROADS

A. Inspecting axle load B. Issuing business licenses C. Measuring vehicle dimensions D. Reporting scale malfunctions
Answer: B. Issuing business licenses
Rationale: Issuing business licenses is the responsibility of local

focus on load compliance, recordkeeping, and equipment monitoring.
29. What does it mean if a vehicle is non-compliant?
A. It has no cargo B. It exceeds size/weight limits or lacks permit C. It is in good condition D. It is a government vehicle
Answer: B. It exceeds size/weight limits or lacks permit
