Are You Driving a "Heavy Vehicle" Without Knowing It?

If you own a pick-up, small truck, or trailer in Zimbabwe, you might be driving a roadside traffic fine waiting to happen. Many motorists are caught completely off guard at VID or ZRP checkpoints when learning that their vehicle is legally classified as a ‘heavy vehicle’ under the Road Traffic Act (Chapter 13:11). To protect you from roadside debates and ensure your journeys are hassle-free, here are Big Sky Supplies’ notes on what constitutes a heavy vehicle or trailer in Zimbabwe—and the statutory guidelines your vehicle or trailer must meet to be fully compliant.

The Short Version:

Under the Road Traffic Act (Chapter 13:11), a “heavy vehicle” is defined as a motor vehicle exceeding 2 300 kg nett mass, but excludes a passenger vehicle having seating accommodation for less than eight passengers.
Under the same Act, a “light trailer” means a trailer with a factory rated load capacity not exceeding 550 kg. Therefore, although not written in law, a heavy trailer has a factory-rated load capacity of 551 kg and above.
Speed monitoring and speed limiting devices are mandatory for heavy vehicles with a NVM of 4 600kg or more.

The documents you and your company drivers’ will find very useful at ZRP checkpoints are available under the “Roadblock Kit” section.

The Long Version:

The relevant legislation is the Road Traffic Act (Chapter 13:11), the Vehicle Registration and Licensing Act (Chapter 13:14), and the Vehicle Registration and Licensing Regulations, 1999 (Statutory Instrument 427 of 1999).
To clarify, the Acts are the senior piece of legislation, as passed by parliament. The Regulations are subsidiary legislation, which the Minister has gazetted, and usually clarifies or updates the relative content in the Act. For context:

The Road Traffic Act (“Driver and Road Rules”). This Act focuses primarily on the people using the roads and the rules to be followed, such as driver licensing, rules of the road, etc.
The Vehicle Registration and Licensing Act (The “Vehicle Identity”). While the Road Traffic Act manages the driver, this Act focuses on the vehicles.
S.I. 427 of 1999: Vehicle Registration and Licensing Regulations (The “How-To” rulebook) The Statutory Instrument is a set of detailed administrative rules created under the authority of the broader Acts. S.I. 427 of 1999 was created specifically under the authority of the Vehicle Registration and Licensing Act to provide the day-to-day, practical steps for registering and licensing a vehicle

Under the Road Traffic Act (Chapter 13:11), a “heavy vehicle” is defined as a motor vehicle exceeding 2 300 kg net mass, but excludes a passenger vehicle having seating accommodation for less than 8 passengers. (See Part 1(2) Interpretation. Definition amended by section 2 of Act 3 of 2000).

A “light trailer” means a trailer fitted with pneumatic tyres, with a factory rated load capacity not exceeding 550 kg. (Road Traffic Act (Chapter 13:11), Part 1(2) Interpretation). Therefore, a trailer with a factory-rated load capacity of 551 kg and above, is classified as a “heavy trailer”.

Vehicle Registration:

Vehicle registration fees fall under the Vehicle Registration and Licencing Act (Chapter 13:14). The fees schedule currently appears in S.I. 10 of 2026, published on 12.01.26. There is no reference to vehicle mass in the schedule; the metric used is engine capacity (above or below 1 500 cc). Registration is administered by Central Vehicle Registry (CVR).

Vehicle Licensing:

Vehicle licensing fees also fall under the Vehicle Registration and Licencing Act (Chapter 13:14). The fees schedule currently appears in S.I. 67 of 2024, published on 12.04.26. The Vehicle Classifications and Tariffs Schedule is found under Part II. In this Schedule vehicles are classified by weight. Vehicle licencing is administered by the Zimbabwe National Roads Authority (ZINARA).
