ALL
QUESTIONS TOGETHER.
1: What is the maximum legal overall width of a motor vehicle or trailer, whether laden or unladen?
Answer: The maximum legal width is 2.6 metres. This limit ensures that
vehicles can safely navigate roads, bridges, and other structures without
causing accidents or damage.
2: What is the maximum legal overall height of a motor vehicle from the road surface?
Answer: The height is limited to 4.6 metres to guarantee safe clearance
under bridges, tunnels, and overhead structures, preventing collisions and
infrastructure damage.
3: What is the maximum legal length of a rigid vehicle?
Answer: A rigid vehicle cannot exceed 12.5 metres. Rigid vehicles have a
single, fixed chassis where the cab and cargo section are permanently attached.
This ensures safe maneuverability, especially in urban and confined areas.
4: What is the maximum legal length for an articulated vehicle?
Answer: Articulated vehicles can be up to 17.0 metres long. They consist
of a separate cab and trailer, and this length ensures safe navigation of roads
and junctions.
5: What is the maximum length allowed for any combination of vehicles?
Answer: Vehicle combinations must not exceed 22.0 metres in total. This
regulation prevents overly long vehicle combinations from creating hazards or
damaging road infrastructure.
6: Which condition may be imposed to enhance safety during transit?
Answer: The use of escorts may be required. Escorts guide vehicles
carrying abnormal or heavy loads, ensuring other road users are warned and
reducing the risk of accidents.
7: What is one key responsibility of a weighbridge officer?
Answer: Weighbridge officers are responsible for monitoring and
verifying vehicle weights. This ensures regulatory compliance, prevents road
damage, and promotes road safety.
8: What actions regarding a special permit are considered offences?
Answer: Altering, defacing, forging, or interfering with a permit with the intent to deceive is an offence. These rules prevent misuse of permits and
ensure vehicles comply with safety regulations.
9: How does computer literacy help a weighbridge officer?
Answer: Computer skills enable officers to manage data, analyze vehicle
weights, and prepare accurate reports efficiently, improving decision-making
and operational effectiveness.
10: What is the minimum fine for failing to comply with a special permit condition?
Answer: The minimum fine is 2,000 US dollars or its Tanzanian shilling
equivalent. This penalty encourages compliance with permit conditions and
deters violations.
11: When is an axle or group of axles deemed overloaded for enforcement purposes?
Answer: An axle is considered overloaded when the weight exceeds 105% of
the legal limit, rounded down to the nearest 100 kg. This accounts for minor
weighing variations while maintaining safety standards.
12: According to the Road Traffic (Maximum Weight of Vehicles) Regulations, who is liable to pay the prescribed fees for vehicle overload offences?
Answer: The owner of the overloaded vehicle is responsible for paying
the fees, as they are legally obliged to ensure compliance with vehicle weight
regulations.
13: When must overload fees be paid?
Answer: Overload fees must be paid on the spot to the Road Authority.
Immediate payment ensures compliance and discourages repeated violations.
14: What is required for a vehicle carrying an abnormal load that exceeds legal dimensions but not axle load limits?
Answer: The vehicle must pay an abnormal permit fee of 20 US dollars (or
TZS equivalent) and obtain a permit from the Road Authority. This ensures safe
transport and regulatory compliance.
15: Can a person with outstanding debts under the Road Traffic (Maximum Weight of Vehicles) Regulations be issued a special permit?
Answer: No, the person is disqualified until debts are cleared.
Compliance with payment obligations is mandatory before permits are issued.
16: Does liability for overload fees exclude penal sanctions for other traffic offences?
Answer: No, paying overload fees does not exempt a vehicle or driver
from other traffic penalties. Other offences may still be prosecuted under the
law.
17: For how many consecutive days will the Road Authority detain an overloaded vehicle free of charge?
Answer: Overloaded vehicles are detained free of charge for three
consecutive days, after which additional detention fees apply.
18: What is the daily detention fee charged after the three free days if an overloaded vehicle remains unpaid for?
Answer: The fee is 20 US dollars per day (or TZS equivalent) until proof
of payment is produced. This encourages the timely settlement of fees.
19: What is the penalty for bypassing or absconding from a weighbridge station, even if the vehicle is not overloaded?
Answer: The penalty is 2,000 US dollars. This ensures that all vehicles
comply with mandatory weighing regulations for road safety.
20: What consequence follows if the owner of a detained vehicle does not pay imposed fees within 90 days?
Answer: The Road Authority may issue a notice of sale by auction. This
enforcement ensures recovery of fees from non-compliant vehicle owners.
21: Before weighing begins, what is the duty of the authorized officer?
Answer: The officer must ensure the scale is set to zero. This
guarantees accurate weighing of vehicles.
22: When using a single axle weighbridge, how is the gross vehicle mass determined?
Answer: The gross vehicle mass is calculated by summing the weights of
all axles. This ensures the total vehicle weight is accurately recorded.
23: To whom may a person appeal if aggrieved by the decision of the Road Authority or an authorized officer refusing a permit?
Answer: An appeal may be made to the Minister responsible for roads, as
the first level of administrative review under the Road Traffic (Maximum Weight
of Vehicles) Regulations.
24: If a person is dissatisfied with the Minister’s decision, where can they appeal further?
Answer: Further appeals can be made to the High Court of Tanzania. This
provides a judicial avenue for review beyond administrative decisions.

This distinction helps in planning, maintenance, and management of the road
network.

local community access.
