A general duty, not a certificate
It's easy to assume "roadworthy" only comes up at a testing station, because that is the one place the word is officially stamped on a piece of paper. The Act says something broader than that.
Section 42(1) of the National Road Traffic Act states plainly: "No person shall operate a motor vehicle which is not in a roadworthy condition on a public road." That is a standing duty on every driver, every time, not a periodic event. Section 42(2) is the separate requirement — a roadworthy certificate, for the classes of vehicle prescribed in Chapter V of the regulations — and it is easy to conflate the two because they share a section number and a word.
The Act defines "roadworthy" as a vehicle which complies with the relevant provisions of the Act and "is otherwise in a fit condition to be operated on a public road". That second half is doing real work: a car can hold a valid roadworthy certificate from last year and still fail section 42(1) today, if something has since broken.
What actually defines "roadworthy", regulation by regulation
The Act's general duty is not a checklist in itself — it is a conclusion. What it rests on is a long run of separate, specific regulations, each governing one system: regulation 149 requires working brakes, regulation 157 requires working lights, regulation 203 requires a working windscreen wiper, regulation 204 requires an unobstructed view and functioning mirrors, regulation 212 sets the tyre condition and tread standard, and regulation 213 requires any fitted seatbelt to be in good working order.
None of these regulations is written as a single combined "before you drive" procedure. Each stands alone, and each applies at all times the vehicle is on a public road — not once at a testing station and then forgotten. Together, they are what "roadworthy" actually means for an ordinary car, component by component.
Where the equipment duties actually live
This is not a legal checklist procedure — it is the regulation you'd be checking compliance with, system by system, if you looked over your car before setting off.
| System | The regulation that governs it |
|---|---|
| Lights | Regulation 157 — lit between sunset and sunrise, and whenever visibility requires it |
| Tyres | Regulation 212 — tread depth, damage, bulges and cuts |
| Brakes | Regulations 149 and 155 — service, parking and emergency brakes, each to a performance standard |
| Windscreen wiper | Regulation 203 — at least one, working continuously, evenly and adequately |
| Mirrors and view | Regulation 204 — a clear reflection of traffic to the rear, and an unobstructed view ahead |
| Seatbelts | Regulation 213 — fitted seatbelts must be in good working order |
Each of these is examined in more depth on its own page in this cluster — this table is the map between them, not a new set of rules.
So is a pre-drive check a legal requirement or good practice?
Both, in different ways, and the distinction matters more than it might seem. It IS the law that your vehicle be roadworthy every time you drive it — that part is section 42(1), a genuine offence provision. It is NOT the law that you must run through a specific numbered sequence of checks before starting the engine — no such procedure appears in the Act, the regulations, or any of the three Department of Transport learner-driver manuals searched for this page.
The practical consequence is that looking over your lights, tyres, mirrors and wipers before you drive off is simply the sensible way to satisfy a duty the Act already places on you continuously. It is good practice built on a real legal foundation, not a separate rule with its own number to memorise.
The mistake
Treating a roadworthy certificate as proof the vehicle is fine today. Section 42(1)'s duty is continuous — a blown bulb or a tyre that has since gone bald puts you in breach of the Act regardless of what the certificate says.
The other one, on the exam paper: assuming there is a named "pre-drive check" regulation to quote. There is a general duty and a long list of component-specific rules behind it, and the honest answer to "which regulation covers a pre-drive check" is that no single one does.

Take the free readiness testCommon questions
Is it a legal requirement to check your vehicle before driving?
The underlying duty is legal — section 42(1) of the National Road Traffic Act requires your vehicle to be roadworthy whenever it is on a public road. There is no separate regulation requiring a specific checklist procedure before you set off; the duty is continuous rather than a one-time act.
What does "roadworthy" mean in South African law?
The Act defines it as a vehicle that complies with the relevant provisions of the Act and is otherwise in a fit condition to be operated on a public road. A valid roadworthy certificate does not by itself guarantee this — the condition can change afterwards.
Is a roadworthy certificate the same as a pre-drive check?
No. A roadworthy certificate is a periodic certification under section 42(2) and regulations 138 to 145, required for prescribed classes of vehicle. The general duty to keep the vehicle roadworthy under section 42(1) applies every time you drive, certificate or not.
What should you actually check before driving?
There is no single official checklist, but the equipment regulations point to the systems that matter: lights (regulation 157), tyres (regulation 212), brakes (regulations 149 and 155), wipers (regulation 203), mirrors and your view of the road (regulation 204), and seatbelts (regulation 213).
Is a pre-drive check examined in the K53 learner's test?
Not as a named topic. The regulations behind individual controls — lights, tyres, brakes, mirrors — are examinable, and a pre-drive check is simply the practical habit of confirming those same things are in order before you set off.

The roadworthiness duty exists; a checklist procedure to satisfy it does not appear in these sources.
