Driving while taking medication

1. The most important things in a nutshell

Driving a car while taking medication is permitted according to the road traffic regulations if the medication is necessary to treat an illness and - very importantly - has been prescribed by a doctor. In addition, the attending physician must assess the patient's fitness to drive and provide the patient with information.

2. Obligation to take medication: check your driving ability yourself

In the case of proven poisoning and other effects of drugs that impair the ability to drive a motor vehicle, the prerequisite for driving motor vehicles of all kinds is until they have completely subsided Not given. In principle, doctors are Committed, Drivers license holders who are dependent on medication, e.g. painkillers or psychotropic drugs, to point out possible restrictions and dangers. This notice is usually given in writing and confirmed by the patient. Otherwise doctors could be held responsible for the costs of possible accidents.

The following intoxicating substances and substances are expressly not permitted in the Road Traffic Act (appendix to ยง 24a StVG): Amfetamine, designer amfetamine, benzoylecgonine, cannabis, cocaine, heroin, metamfetamine, methylenedioxyamfetamine (MDA), methylenedioxyethylamfetamine (MDE), methylenedioxymetMAfetamine , Morphine, tetrahydrocannabinol (THC). They may only be taken as intended for a specific case of illness and must be prescribed by a doctor (Section 24a (2) StVG).

If a patient is allowed to drive a car despite these medications, they should have this confirmed in writing by the doctor. This confirmation is usually only given if the patient regularly takes his medication according to the instructions and is in a good, stable general condition, and if the therapy is effective.

Medicines are never allowed suddenly discontinued because both the withdrawal itself and the lack of medication can make it unfit to drive. Changes should always be made in consultation with the doctor.

Particular attention should be paid when starting drug treatment. But even later, and especially in the case of chronic and serious illnesses, the doctor must conduct the therapy and monitor it regularly.

Basically: Even if the doctor gives the general permission to drive, the patient must before every trip critically assess his / her fitness to drive. If the patient is concerned about their fitness to drive, it is better to use a taxi or public transport.

3. Driving a car with certain illnesses and ailments

The assessment of driver skills in connection with medication must always be viewed in a very differentiated manner. On the one hand, there are diseases that exclude driving (e.g. epilepsy) - but with the help of medication, fitness to drive can be restored. On the other hand, there are illnesses that do not affect driving - but the drugs (e.g. strong painkillers or psychotropic drugs) reduce performance for road traffic, e.g. by slowing down or having difficulty concentrating.

As a rule, the reduction in mental and / or physical performance is detrimental to driving motor vehicles. Painkillers, sleeping pills and sedatives (tranquilizers), anticonvulsants, neuroleptics, antidepressants and antiallergics are of particular importance here.

3.1. Cardiovascular funds

Most cardiovascular diseases are permanently treated with medication. These work very differently. The following are the most common impairments for driving a car:

  • Anticoagulants (blood thinners) carry the risk of acute bleeding. The treatment should be regularly monitored by a doctor and fitness to drive should be confirmed by a corresponding certificate.
  • Drugs of the digitalis group can Cause rhythm disturbances, rarely also visual disturbances or acute psychological disturbances. Here too, medical supervision with evidence is indicated.
  • Antihypertensive drugs (blood pressure lowerers) cause dizziness and fainting if the blood pressure is lowered too much.

3.2. Psychiatric drugs

If patients are treated with higher doses of psychoactive drugs, this may affect their ability to drive, regardless of whether the actual illness affects the person's ability to adapt and perform.

3.3. Taking opioids

Various studies on the fitness to drive while taking opioids have shown that with a stable dose, in general, exercise tolerance, concentration, orientation, attention or ability to react are not significantly impaired.

Nevertheless, the following must be taken seriously with opioids, e.g. also with pain plasters:

  • Patients who are able to drive should have an opioid ID with them. You can download it here as a PDF file, cut it out and fold it along the lines (first in the middle) to keep it in your wallet. The doctor notes on the opioid ID card that the person concerned is dependent on these drugs.
  • During the Recruitment phasee.g. of morphine, driving a vehicle will probably not be possible, as attention-impairing side effects are common in the first 14 days and after each dose increase. For well-adjusted patients who no longer suffer from visual disturbances, tiredness, nausea, vomiting or dizziness, nothing stands in the way of driving a car.

3.4. Medical cannabis

When prescribing cannabis by a doctor, special rules regarding the ability to drive may apply, see Medical cannabis for more information.

3.5. Dizziness from medication

Dizziness can be a side effect of centrally acting drugs such as psychotropic drugs or anti-high blood pressure drugs. This can severely limit suitability for road traffic. Therefore, if you feel dizzy as a result of medication, you are not allowed to drive a vehicle. Exceptions are possible, taking into account the guidelines for long-term drug therapy.

3.6. alcohol and drugs

Since alcohol can increase the side effects of medication, it should be avoided completely - and not just with a view to driving a car.

Anyone who is addicted to alcohol can Not Drive.

Anyone who takes narcotics or is dependent on them cannot drive a car. However, fitness to drive may be given if the agent has been prescribed by a doctor and is taken as intended, i.e. if no There is addictive behavior.

If you have lost your driving license as a result of addiction to alcohol or drugs, you will usually only get it back if you can prove a successful withdrawal treatment and a year-long abstinence (proven by medical examinations). A psychological report and, in some cases, a new driving test are also required. In addition, the consumption of addictive substances must not have caused any damage to the central nervous system or personality changes that affect the ability to drive.

4. Assessment of fitness to drive

The guidelines can be downloaded free of charge from> Behavior and Safety> Technical Topics> Assessment guidelines for suitability for driving> below "for download ..."> above "assessment guidelines ..."> right "full text ...".

Fitness to drive is assessed separately for group 1 (e.g. motor vehicle) and 2 (e.g. truck, passenger transport). More details under driving license groups.
