Key Points at a Glance: Traffic Violations & Driver’s License Suspension
➤ The Tricky Dual Track: One Incident, Two Proceedings. In cases of traffic violations, the public prosecutor’s office (criminal law) and the Department of Motor Vehicles (administrative law) conduct investigations in parallel and often independently of one another.
➤ The “cascade trap”: What begins with a fine or a suspended fine usually leads, as a second step, to the mandatory revocation of a driver’s license. In the event of repeated violations, the penalties are increased. For speeding offenses or driving under the influence of alcohol or drugs (FiaZ), drivers face not only a precautionary license suspension but also costly traffic psychology or medical evaluations.
➤ The defense strategy: Anyone who accepts a penalty order without challenging it effectively makes the revocation of their driver’s license permanent. Our goal is to strategically coordinate both proceedings from the very beginning in order to minimize the legal consequences as much as possible.
Time as a Risk Factor
In traffic law, the most important decisions are made during the initial interviews. Anyone who acts here without legal consultation risks severe professional and personal consequences..
Many people only concern themselves with the Road Traffic Act (SVG) once their driving license has already been confiscated or a penalty notice has arrived in the mailbox. For many of those affected, this poses an acute threat to their professional and private existence.
This guide will lead you through the jungle of Swiss authorities and show you how to react correctly at every stage of the procedure.
The underestimated dual track: one incident – two proceedings
The biggest surprise for most clients is the fact that in the case of a traffic offense in Switzerland, not just one, but two authorities usually take action against you in two proceedings with completely different rules and largely independently of each other.
1. criminal proceedings (public prosecutor’s office & courts)
Here it is checked whether you have violated the penal provisions of the Road Traffic Act (SVG). The authorities classify the offense as a simple, gross or qualified gross violation of traffic regulations (speeding offense). This often results in a criminal sanction: a fine, a fine or – in the case of serious offenses – a prison sentence.
2. the administrative procedure (Road Traffic Office)
The focus here is on road safety. The road traffic office responsible for your place of residence will classify your offense as a minor, moderate or serious offense. Based on this, the office will decide on administrative measures such as a warning or the withdrawal of your driver’s license.
Important: If there are doubts about your general fitness to drive right from the start (e.g. suspicion of addiction or medical problems), the office can also order a precautionary withdrawal – your driving license is then immediately removed even before the actual procedure has been completed.

Driving license revocation Switzerland: How the authorities assess your fault
Before deciding on the duration of a deportation order or the amount of the fine, the authorities must classify the incident in legal terms. This classification is at the heart of any defense strategy:
Criminal classification by the public prosecutor’s office & courts
Simple traffic rule violation: minor fault, usually only a fine. Usually no entry in the criminal record.
Gross violation of traffic regulations: Reckless behavior that creates a serious danger for others. Consequence: fine and entry in the criminal record.
Qualified gross violation of traffic regulations: the so-called speeding offense. Consequence: Mandatory prison sentence and entry in the criminal record.
The administrative qualification (Road Traffic Office)
The Road Traffic Licensing Office is generally bound by the findings of the criminal proceedings, but has its own leeway in determining the measure:
Minor offense: As a rule, a warning is issued. Withdrawal of at least one month only occurs in the case of previous offenses.
Moderate offense: The driver’s license is revoked for at least one month .
Serious offense: Withdrawal lasts at least three months. In the case of speeding offenses, the withdrawal is at least two years. In addition, a traffic psychologist’s report is mandatory.
Classic offense areas and their pitfalls

Frequently asked questions (FAQ): Road traffic law & driving license revocation
This is the most common misconception surrounding the withdrawal of a driver’s license. Throughout Switzerland, the so-called dual-track procedure applies in such cases. The public prosecutor’s office punishes you for the offense (e.g. with a fine), while the Road Traffic Licensing Office takes road safety measures independently of this (e.g. withdrawing your license). Paying the fine does not stop the proceedings at the Road Traffic Licensing Office – on the contrary: by paying, you accept the facts of the case, to which the Road Traffic Licensing Office is then legally bound.
This depends on where you were flashed and whether you have already received a warning in the last two years. If you have a “clean” ticket, the ticket is lost for at least one month after deduction of the safety margin from the following values (medium offense):
-
In urban areas: from 21 km/h too fast
-
Out of town: from 26 km/h too fast
-
Highway: from 31 km/h too fast
Please note: You will receive a warning (minor offense) for even minor violations (e.g. 16 km/h in urban areas or 26 km/h on the highway). If you then commit another offense in the next two years, the cascade system will take effect and your license will be forfeited. If you drive at even higher speeds, you could face a much longer ban or even speeding proceedings.
Warning withdrawal: This is an educational “reminder” for a clearly defined period of time (e.g. 1 or 3 months). At the end of this period, you will automatically receive your ID card back.
Provisional withdrawal: This is imposed if there are doubts about your general fitness to drive (e.g. from 1.5 per mille alcohol, drug use or serious medical problems). The license is withdrawn indefinitely. You will only get it back when you can provide positive proof of your fitness to drive by means of an expert opinion (traffic doctor, hair test, traffic psychologist’s report).
Yes, this is possible, but the legal route is different from that of a car. In the case of a bicycle or a slow e-scooter (up to 20/25 km/h), there is generally no direct “warning withdrawal” (e.g. for 3 months). Instead, the Road Traffic Licensing Office will check your basic fitness to drive on the basis of the police report (Art. 15d SVG). If you have high alcohol levels or have taken drugs, there are doubts as to whether you can safely drive at all. If the ordered traffic medical examination is negative, your driver’s license may be withdrawn indefinitely. In the case of “fast” e-bikes (up to 45 km/h), on the other hand, a direct warning withdrawal is possible for all categories.
In the case of simple administrative fines, the case is usually closed once the fine has been paid. However, when it comes to more serious offenses (which lead to criminal proceedings and deportation), many managing directors fall into a dangerous liability trap: the so-called “owner indication”. According to case law, there is a presumption that the owner – in the case of companies, the person responsible (e.g. the managing director) – drove the vehicle themselves. If you invoke your right to silence across the board and do not provide a plausible explanation as to who else was driving, the court will often count this against you. This means that you personally could face a criminal conviction and the withdrawal of your driver’s license. Furthermore, there is no obligation to incriminate yourself, but anyone who knowingly lies to cover up for an employee may be liable to prosecution for abetting or misleading the administration of justice.
