A vehicle roadworthy certificate in South Africa is a statutory requirement under the National Road Traffic Act, legally mandated whenever a vehicle changes ownership or is registered in a new owner’s name. The official roadworthy inspection evaluates critical safety and operational components—including the braking system, tyres, steering, suspension, lighting, engine, and structural integrity—to ensure the car meets SANS 10047 national safety standards. Passing this test confirms that a vehicle is mechanically sound and safe to operate on public roads.
Understanding South African Roadworthy Requirements
Before taking a vehicle to an accredited testing station, it is essential to understand the legal framework and baseline requirements governing roadworthiness in South Africa.
Legal Mandate and Relevant Regulations
Under the National Road Traffic Act (Act No. 93 of 1996), every motor vehicle driven on South African public roads must be in a roadworthy condition. While private passenger vehicles are not subjected to annual roadworthy inspections, a valid Roadworthy Certificate (RWC) is compulsory during ownership transfers, vehicle re-registrations, or when converting a private car for commercial or public transport use. Testing stations conduct checks in accordance with South African National Standards (SANS 10047 for roadworthiness testing).
Vehicle Identification and Documentation Checks
The inspection begins with a verification of the vehicle’s legal identity. Examiners match the physical vehicle with its official documentation to prevent fraud and illegal vehicle cloning:
- VIN and Engine Numbers: The Vehicle Identification Number (VIN) stamped on the chassis and the engine number must match the details recorded on the National Traffic Information System (eNaTIS) and registration certificate (RC1).
- Tamper Verification: Stamping marks and VIN plates are inspected for any signs of grinding, welding, or illegal alterations.
- Registration Papers: You must present the original vehicle registration certificate and the owner’s valid South African ID document at the testing center.
Detailed Roadworthy Checklist for Cars
To ensure a first-time pass, vehicle owners should inspect their cars against the official evaluation areas outlined below prior to booking a test.
1. Wheels, Tyres, and Spare Tyre Specs
Tyres are the only contact point between the vehicle and the road surface, making them a primary focus during inspection:
- Tread Depth: All tyres—including the spare wheel—must have a minimum tread depth of 1.6 mm across the entire tread surface.
- Physical Condition: Tyres must be free from visible bulges, sidewall cuts, cracks, exposed cord, or uneven tread wear caused by alignment issues.
- Specification & Sizing: All fitted tyres and wheels must match manufacturer specifications and be correctly sized for the vehicle axle.
- Spare Wheel: The spare tyre must be securely mounted, properly inflated, and meet all standard tyre condition rules.
2. Braking System and Components
Braking efficiency is evaluated on a roller brake tester to measure stopping force and balance across all wheels:
- Service Brakes: Foot brakes must operate evenly across both left and right wheels without pulling or fading.
- Parking Brake: The handbrake (or electronic parking brake) must securely hold the vehicle stationary on steep inclines.
- Discs and Pads: Brake discs must not be excessively worn, grooved, or concave. Pads must have sufficient friction material remaining.
- Hydraulics: The brake master cylinder, calipers, lines, and hoses are checked for fluid leaks, cracking, or soft pedal pressure.
3. Lighting, Indicators, and Electrical Wiring
All exterior illumination and signaling devices must function independently and reliably:
- Headlights: Both high and low beams must function properly, with correct vertical and horizontal beam alignment.
- Brake & Tail Lights: Tail lights, primary brake lights, and high-mounted center stop lamps must illuminate instantly upon pedal depression.
- Indicators & Hazards: All turn signal lamps and hazard warning lights must flash at a consistent, regulated speed.
- Fitment & Lenses: Light housings must be securely attached, water-tight, free from moisture ingress, and fitted with clear, uncracked lenses.
- Electrical System: The battery must be firmly secured with proper hold-down clamps, free of corrosion or acid leaks, and wiring must be insulated without loose, exposed connections.
4. Steering, Suspension, and Alignment
The steering and suspension systems are inspected from both inside the cabin and beneath the vehicle on a pit hoist:
- Steering Play: Excessive free play in the steering wheel or loose steering linkages is an immediate failure point.
- Suspension Components: Control arms, bush mountings, ball joints, kingpins, and anti-roll bars must be securely anchored with no worn rubber bushings.
- Shock Absorbers: Dampers must show no signs of hydraulic fluid leakage and must stabilize body movement effectively.
- Wheel Alignment: Front and rear wheels must be aligned within manufacturer tolerances to prevent vehicle drift.
5. Windscreen, Windows, and Wipers
Driver visibility is crucial for road safety:
- Windscreen Cracks: The windscreen must be free from cracks, stone chips, or discoloration within the driver’s direct field of vision (swept wiper area).
- Wiper Performance: Windscreen wiper arms and blades must operate smoothly and clear water efficiently without leaving streaks or possessing split rubber.
- Window Mechanism: All side windows designed to open must roll up and down without sticking or binding.
6. Engine, Transmission, and Exhaust System
The mechanical driveline is checked for fluid leaks, structural integrity, and environmental compliance:
- Fluid Leaks: The engine bay and undercarriage must be clean and free from active oil, coolant, or fuel leaks.
- Mountings: Engine and transmission rubber mountings must be intact and free from cracks or severe sagging.
- Exhaust System: The exhaust pipe, silencer, and catalytic converter must be securely mounted on rubber hangers, free of blowholes/leaks, and must not emit excessive noise or dark smoke.
7. Bodywork, Interior Safety, and Chassis Integrity
The structural condition of the car is thoroughly vetted:
- Chassis & Undercarriage: The chassis must show no signs of structural weakness, severe rust, or improper frame repairs from past major collisions.
- Body Panels & Doors: All doors, bonnet, and boot lids must latch securely and open effortlessly from both inside and outside. Bumpers and side mirrors must be firmly mounted.
- Seatbelts & Seating: All seatbelts must anchor properly, latch cleanly, retract smoothly, and display no fraying or cut webbing. Seats must remain firmly bolted to the floor pan.
- Instruments & Horn: The speedometer, odometer, and warning horn (hooter) must be fully operational.

Navigating the Inspection Process
Approved Testing Stations and Requirements
Roadworthy tests in South Africa can be conducted at either public vehicle testing stations (municipal traffic departments) or private, accredited testing stations (such as DEKRA or AVTS). When taking your vehicle for inspection, ensure you bring:
- The original vehicle registration certificate (RC1).
- A valid South African ID document or smart card.
- The prescribed inspection fee (typically ranging between R450 and R700 depending on the facility and vehicle class).
- A completed Application for Certification of Roadworthiness (ACR) form.
Retest Rules and Common Inspection Pitfalls
If your vehicle fails the initial inspection, the testing station will issue a failure report detailing the specific defects. Under South African regulations:
- 14-Day Grace Period: You are generally granted 14 calendar days to rectify the noted defects and return the vehicle to the same testing station for a re-inspection.
- Re-test Fee: Many stations conduct the re-test for free or at a reduced rate if brought back within the 14-day window.
- Full Re-inspection: Failing to return within 14 days requires you to pay the full fee again and undergo a brand-new inspection from scratch.
Frequently Asked Questions
Is a roadworthy certificate mandatory when buying or selling a car in South Africa?
Yes. A valid Roadworthy Certificate is legally required whenever a vehicle changes ownership in South Africa. The Department of Transport will not issue a new license disc or complete the registration of the vehicle in the new owner’s name without a valid RWC.
How long is a South African Roadworthy Certificate valid?
A Roadworthy Certificate is valid for 60 days from the date of issue. The vehicle ownership transfer and registration process must be completed within this 60-day window, or a new roadworthy inspection will be required.
What happens if a car fails the roadworthy inspection test?
If a vehicle fails, the examiner provides a failure report detailing all non-compliant components. You are given 14 calendar days to repair the listed faults and return the car to the same testing station for a focused re-test.
How much does a roadworthy test cost in South Africa?
The cost of a roadworthy test varies depending on whether you choose a municipal or private testing station, as well as the vehicle category (light motor vehicle vs. heavy commercial vehicle). Standard passenger car tests generally cost between R450 and R700.
Does the spare wheel need to pass the roadworthy inspection?
Yes. The spare tyre is subjected to the exact same safety standards as the four road tyres. It must have at least 1.6 mm of tread depth, hold correct air pressure, and be free from structural defects or cracks.
Can a car pass roadworthy with a cracked windscreen or minor body rust?
A car will fail if a windscreen crack or stone chip falls within the driver’s direct line of sight (the wiper sweep area). Minor surface rust on body panels may pass, but structural rust on the chassis, door sills, or suspension mounting points will result in an immediate failure.
