Eye Test for Driving Instructors (Fahrlehrer)
Introduction
Eye test for driving instructors is the first medical step for anyone who wants to teach people to drive in Germany. A Fahrlehrer, or driving instructor, sits next to a learner driver every day, watches the road, checks the mirrors, and has to react in a fraction of a second if the learner makes a mistake. That job needs excellent eyesight, and the German rules say so clearly. If you are an expat who already holds a driving licence and you want to become a driving instructor in Germany, you will need to pass an eye test for driving instructors, a medical examination, and a series of professional tests before you can teach your first pupil.
Eye test for driving instructors is stricter than the standard eye test for a car driving licence, and it works in a different way. The standard Sehtest at the optician is a screening test for private drivers, and it costs only a few euros. The eye test for driving instructors is part of a full medical examination, and it follows the rules for professional drivers, because an instructor is a professional driver and a teacher at the same time. The medical check looks at your visual acuity, your visual field, your colour vision, and your general health, and the results go to the driving licence office in a report.
In this article, you will learn what an eye test for driving instructors involves, which visual acuity you need, how the medical examination works, what the difference is between teaching car drivers and teaching lorry or bus drivers, and how often the test has to be repeated. You will also find practical advice on preparing for the test, on what happens if you fail, and on the language and qualification requirements for expats who want to work as a Fahrlehrer in Germany. By the end, you will know exactly what to expect and how to take the first step towards a driving instructor licence.

What Is a Fahrlehrer, and Why Is the Eye Test Stricter?
A Fahrlehrer is a licensed driving instructor in Germany. The job is regulated by the Driving Instructors Act, the Fahrlehrergesetz, and it requires a licence of its own, the Fahrlehrerlaubnis, which is issued by the driving licence office. To get it, you must hold the driving licence for the class you want to teach, you must be at least 21 years old for car instruction and 24 for some other classes, you must have held your licence for a set period, and you must pass a medical examination, a test of your professional knowledge, and a practical teaching examination. The eye test for driving instructors is part of that medical examination.
The eye test is stricter for instructors because their responsibility is greater than that of a private driver. A private driver is responsible for herself and her passengers. An instructor is responsible for a learner who makes mistakes, for the pupils in the cars around her, and for the reputation of the driving school. The instructor must see a hazard before the learner does, must read road signs and judge distances quickly, and must be able to teach a learner to do the same. Poor eyesight in an instructor is a risk to the learner, to other road users, and to the instructor herself, and the German rules are written to prevent it.
Eye test for driving instructors also matters because instructors work long hours in the car, often in poor light and in bad weather. They drive in the morning rush hour, in the evening, and in rain and fog, and they need eyes that can cope with glare, with low contrast, and with long hours of concentration. The medical examination checks not only visual acuity, but also the health of the eyes, because a cataract or a retinal disease can get worse over the years and become a problem in the middle of a career. That is why the eye test is not a one-off check, but part of a system of regular medical checks for professional drivers.
Eye Test for Driving Instructors: The Visual Acuity Rules
Eye test for driving instructors follows the medical fitness rules in the driving licence regulation, the Fahrerlaubnis-Verordnung, and its annex on fitness to drive. For a car instructor, the visual acuity rules are the same as those for a car driver in principle, but the assessment is carried out by an ophthalmologist or a doctor who specialises in occupational medicine, and the result is written in a medical report, not on a simple optician certificate. The instructor needs a visual acuity of at least 0.7 with both eyes together, with or without glasses or contact lenses, and the visual field must be normal.

For instructors who teach lorry or bus drivers, the rules are stricter, because they follow the rules for professional lorry and bus licences, Group 2. A Group 2 driver needs a visual acuity of at least 0.8 in the better eye and 0.1 in the worse eye, a normal visual field in both eyes, and no eye disease that could affect driving. A lorry or bus instructor who cannot meet those limits cannot teach that class, although she may still be able to teach car drivers. The medical report will state exactly which classes the instructor is fit to teach, and the licence office will issue the instructor licence for those classes only.
Colour vision is also checked for driving instructors, because instructors must be able to read traffic lights and road signs correctly and to teach learners to do the same. A mild colour vision deficiency does not normally stop a person from becoming an instructor, but a severe deficiency can be a problem, especially for lorry and bus instruction. The medical examination includes a colour vision test, such as the Ishihara test, and the ophthalmologist will note the result. If you know that you are colour-blind, tell the doctor before the test, because a simple note in the report can save time.
The Medical Examination in Detail
The medical examination for a driving instructor is usually done by an ophthalmologist or by a doctor at a technical inspection centre, such as the TueV or Dekra, or by an occupational health doctor, a Betriebsarzt. It includes a visual acuity test, a visual field test, a colour vision test, and a check of the health of your eyes, including the lens, the retina, and the eye pressure. It also includes a general health check, including blood pressure, hearing, and a check for conditions that could affect driving, such as diabetes, epilepsy, and heart disease. The whole examination usually takes between 30 and 60 minutes, and it costs between 100 and 250 euros, depending on the doctor and the state.
Bring your identity card, your driving licence, your glasses or contact lenses and your current prescription, and any medical reports about your eyes or your general health. Tell the doctor if you have diabetes, high blood pressure, or any medication that could affect your eyes, because that information helps the doctor to write a clear report. If you wear glasses, the report will state that you must wear them while teaching, and your instructor licence and your driving licence will both carry that condition. If you fail the medical examination, the doctor will explain why and what you can do about it.
How the Eye Test for Driving Instructors Differs from the Standard Sehtest
The most important difference is that the standard Sehtest is done at an optician and produces a certificate that the licence office accepts automatically for a private licence. The eye test for driving instructors is done by a doctor, and it is part of a medical report that the licence office reads and decides on. The optician cannot do the instructor medical examination, and a certificate from an optician is not enough for a Fahrlehrer licence. If you go to an optician and ask for the instructor test, you will be sent to a doctor, and you will have wasted a visit.
The second difference is that the instructor medical examination is more detailed. It includes a colour vision test and a full eye health check, which the standard Sehtest does not include, and it includes a general health check. The third difference is that the result is not a simple pass or fail. The doctor can recommend a licence with restrictions, for example a requirement to wear glasses, a limit to teaching car drivers only, or a requirement to have your eyes checked again after one year. The licence office follows the doctor’s advice, and the instructor licence is issued with those restrictions written on it.
The Application Process for a Fahrlehrer Licence
The application process starts with the driving licence office in the town where you live. You submit your identity card, your driving licence, your medical report, a recent criminal record check, and proof that you have completed the training course for driving instructors. The training course is long: it takes about a year for car instruction, and it includes theory, practical driving, teaching practice, and a final examination. The course is run by a driving instructor training school, a Fahrlehrerausbildungsstaette, and it costs several thousand euros. Your eye test for driving instructors must be done before the course starts, not at the end, because the licence office will not accept you onto the course if you are not medically fit.
For expats, there are two extra steps. The first is the language requirement. The training course and the examinations are in German, and you need a good level of German, at least B2, to follow the course and to teach your pupils. A eye test for a driving licence will not help you to learn German, but many language schools offer a course that is designed for driving instructors. The second is the recognition of a foreign driving licence or a foreign instructor qualification. The eye test for lorry and bus drivers page explains the Group 2 rules that apply when a lorry or bus instructor is involved, and the driving licence office can tell you whether your foreign documents are recognised in Germany.
Once you have the instructor licence, you must renew it regularly. The instructor licence is valid for five years, and you must pass a new medical examination before it can be renewed. For instructors over 50 who teach lorry and bus drivers, the medical check is every five years, and the eye test is part of it. The instructor must also complete regular further training, called Fortbildung, and must keep the licence up to date, or it will expire and the instructor will not be allowed to teach.

What Happens If You Fail the Eye Test for Driving Instructors
Failing the eye test for driving instructors does not mean that your career is over, but it does mean that you cannot start the training course yet. The doctor will explain whether the problem is a wrong glasses prescription, a cataract, a retinal disease, or a narrowed visual field. In most cases, a new pair of glasses is enough, and a repeat test a few weeks later will show a better result. If the problem is a cataract, surgery can often restore your vision, and your licence can be granted after the operation and a short recovery period. If the problem is a serious eye disease, you may be fit to teach car drivers but not lorry or bus drivers, and the licence office will issue the instructor licence with that restriction.
Eye test for driving instructors is also a good moment to think about your long-term eye health. Instructors spend their working day looking at the road, and that means that a problem with glare, with contrast, or with night vision will affect them more than it affects a private driver. If the doctor says that your eyes are fine now, ask how often you should have them checked, and follow that advice. Keeping your glasses current, wearing sunglasses that fit, and protecting your eyes from the sun are all simple steps that protect a long career as an instructor. And if you do fail the test, remember that the rule is there to protect your future pupils, not to punish you.
