All applicants applying for a new learner’s licence, driving licence, or renewing a driving licence card in South Africa must undergo a mandatory eyesight screening to ensure they meet the visual standards set by the National Road Traffic Act. The test checks visual acuity and visual fields using a specialized electronic screener at the Driving Licence Testing Centre (DLTC), or through an official screening certificate issued by a registered optometrist. Light motor vehicle drivers must achieve a minimum visual acuity of 6/12, while professional drivers (PrDP) and heavy vehicle operators are held to a stricter standard of 6/9 in each eye.
Overview of DLTC Eye Test Requirements in South Africa
Visual awareness accounts for over 90% of the information a driver processes while operating a vehicle. To maintain safety on public roads, the South African Department of Transport requires vision testing across three primary licensing stages:
- Learner’s Licence Applications: First-time drivers must pass the eye test before writing the theoretical exam.
- Driving Licence Card Renewals: Card renewals occur every five years, requiring a fresh eyesight assessment each time.
- Professional Driving Permit (PrDP) Applications & Renewals: Commercial, passenger transport, and heavy vehicle drivers require frequent vision checks upon permit issue and renewal.
The visual evaluation assesses both sharpness of vision (visual acuity) and side vision (horizontal visual fields). If a candidate fails to meet the minimum legal criteria without vision aids, they must wear corrective lenses (spectacles or contact lenses) while driving, which is recorded as an official restriction on their driving licence card.
Visual Acuity Standards by Driver Category
South African law distinguishes between non-professional motorists and heavy vehicle or commercial operators. Visual acuity is measured according to the Snellen fraction scale (or metric equivalent 6/6 notation).
Private Motorists (Code A, A1, B, and EB)
To qualify for a licence to drive motorcycles, light motor vehicles, or small vehicles pulling light trailers, an applicant must meet the following baseline requirements:
- Visual Acuity: A minimum Snellen acuity of 6/12 (20/40) in at least one eye, or in both eyes combined.
- Visual Field: A minimum horizontal visual field of 70 degrees to the left and right (a total combined field of at least 120 degrees).
- Corrective Lenses: Lenses may be worn to reach the 6/12 threshold. If passed using corrective lenses, the driver’s licence card will carry an endorsement code indicating that glasses or contacts must be worn whenever driving.
Heavy Vehicle & Professional Drivers (Code C1, C, EC1, EC, and PrDP)
Because larger vehicles carry higher risk, larger blind spots, and longer braking distances, commercial drivers are held to a higher visual acuity threshold:
- Visual Acuity: A minimum Snellen acuity of 6/9 (20/30) in each eye individually.
- Visual Field: Full peripheral visual field coverage without significant visual defects or scotomas.
- PrDP Restrictions: Commercial passenger drivers (taxis, buses) and hazardous goods transporters cannot obtain a PrDP if visual standards fall below 6/9, even in one eye.
Monocular Vision Drivers (Vision in One Eye)
Drivers who have lost vision in one eye or have functional sight in only one eye can still hold a valid Code B driving licence under strict statutory conditions:
- The functioning eye must achieve an unassisted or corrected visual acuity of at least 6/9.
- The good eye must have an unobstructed horizontal visual field of at least 115 degrees.
- Monocular drivers are generally excluded from holding a Professional Driving Permit (PrDP).
What to Expect During the DLTC Machine Screening
When taking the vision test directly at the licensing department counter, testing is conducted using a tabletop optical screening machine rather than a standard wall letter chart.
The Landolt “Tumbling E” Chart
Instead of asking applicants to read alphabet letters, the DLTC screener displays the “Landolt Tumbling E” symbol. The capital letter “E” appears in various sizes and four orientations:
- Facing Up ($\uparrow$)
- Facing Down ($\downarrow$)
- Facing Left ($\leftarrow$)
- Facing Right ($\rightarrow$)
The test examiner will instruct you to look into the viewer, rest your forehead against the cushion, and indicate which direction the “legs” or “open end” of the E are facing on each row.
Screening Steps
- Right Eye Testing: The examiner isolates the right ocular view to measure single-eye acuity.
- Left Eye Testing: The left ocular view is isolated and measured.
- Binocular Testing: Both eyes are evaluated together to test combined clarity and depth perception.
- Peripheral Vision Sweep: Light indicators flash on the far left and right extremes inside the machine. You must verbally report when you detect a flash on either side without moving your eyes away from the central target.
Common Machine Screening Challenges
Many drivers with perfectly healthy vision experience difficulty or fail the counter machine due to:
- Poor lighting or glare inside the screener viewer.
- Inadequate hygiene or smudges on the optical lenses.
- Physical discomfort from improper seating height or forehead alignment.
- Dry eyes caused by prolonged waiting in licensing department queues.
Bypassing the DLTC Eye Test: Optometrist Eye Certificates
To save time and avoid long queues at the counter machine, drivers in South Africa are legally permitted to have their eyesight tested by a registered private optometrist prior to visiting the DLTC.
Advantages of an Optometric Certificate
- Skip the Queue: Presenting an official eye certificate allows you to bypass the eye-testing desk entirely at the DLTC, shortening your overall renewal time.
- Better Testing Conditions: Examinations conducted in a controlled, clinical environment reduce artificial failures caused by dusty or misaligned counter machines.
- Professional Prescription Updates: If your vision has changed, the optometrist can immediately update your lens prescription before you submit your renewal application.
Key Requirements for the Certificate
- Must be completed by a registered South African optometrist or ophthalmologist.
- Must include the practitioner’s official practice stamp, HPCSA registration number, signature, and date of examination.
- Must explicitly state your visual acuity measurements for each eye, binocular vision, and horizontal visual fields.
- Validity Period: The certificate must not be older than 3 months (90 days) from the date it is presented at the licensing centre.
What Happens If You Fail the Eye Test at the DLTC?
Failing the counter machine test at the DLTC does not mean your application is rejected permanently. If you fail to meet the standard on the machine:
- Official Referral Form: The DLTC official will issue a formal referral notice requesting an evaluation by a private eye care professional.
- Optometric Assessment: You must visit a qualified optometrist for a full visual screening.
- Corrective Action: If your vision improves to legal limits with corrective lenses, the optometrist will issue the standard driving licence eye test certificate specifying that glasses or contacts are required.
- Resubmission: Return to the DLTC with your valid optometrist certificate to finalize your licence application or renewal without re-taking the counter machine test.
Frequently Asked Questions
Can I wear my glasses or contact lenses during the DLTC eye test?
Yes, you are permitted to wear your prescribed glasses or contact lenses during the vision test at the DLTC or during an optometrist screening. If you use corrective lenses to pass the test, your driving licence card will be issued with a driver restriction code (Code 1), making it legally mandatory for you to wear visual aids whenever operating a motor vehicle.
How long is an optometrist eye test certificate valid for at the DLTC?
An official eye test screening certificate issued by a registered optometrist is valid for 3 months (90 days) from the date of issue. You must present the original, stamped, and signed document at the licensing department before this period expires.
What vision standard is required for a Professional Driving Permit (PrDP)?
To qualify for a Professional Driving Permit (PrDP) or heavy vehicle licence (Code C1, C, EC1, EC), applicants must achieve a visual acuity of at least 6/9 in each eye individually, with or without corrective lenses. In addition, commercial drivers must possess full visual fields without uncorrected defects.
What type of vision chart is used at South African DLTCs?
South African Licensing Departments use the Landolt Tumbling “E” style test inside automated vision screeners. Instead of reading letters of the alphabet, you are asked to state the direction in which the legs of the letter “E” are pointing (up, down, left, or right) as the symbols decrease in size.
Can you drive legally in South Africa if you have vision in only one eye?
Yes, monocular drivers can legally hold a Code B (light motor vehicle) driver’s licence in South Africa, provided the good eye achieves a visual acuity of at least 6/9 and maintains a horizontal field of vision of at least 115 degrees. However, monocular drivers are generally disqualified from receiving a Professional Driving Permit (PrDP).
Do I have to pay extra at the DLTC if I bring an optometrist eye certificate?
No, presenting an optometrist eye test certificate does not incur an additional processing fee at the DLTC. While you will pay the optometrist for the private consultation or screening service, the licensing department accepts the official certificate in place of their on-site machine test without charging extra administration fees.
