Too little distance - and suddenly your driver's license is gone!
Why too little distance in road traffic is trickier than many people think
The following situation occurs countless times a day on the roads here: Car driver A wants to overtake car driver B, but car driver C is blocking the overtaking lane in front of him at a leisurely 110 km/h. A drives a little closer, not necessarily aggressively, but in the hope of persuading C to change lanes.
Not in every case, but increasingly often, A receives mail from the police a short time later: due to a distance measurement, criminal proceedings have been opened against him for not driving far enough. Shortly afterwards, the road traffic office also contacts him and wants to revoke his driver’s license.
Everyday situation – with legal risk
Anyone who drives in Switzerland knows that people often slow down in the left lane. If you want to overtake, you sometimes have to wait – and then move a little closer for a few seconds at best. Without indicating, without tailgating, simply as a non-verbal signal. This behavior is widespread. Many people do it – but only a few are caught. And those who are caught face severe consequences.
Distance offenses are therefore one of the most common reasons for driving disqualifications in Switzerland today. On freeways in particular, a brief moment of insufficient distance is often enough to result in severe sanctions.
What is particularly annoying is that while drivers who fail to keep a safe distance are severely penalized, unnecessary driving on the left usually has no consequences.
How is the distance measured?
Police distance measurements are usually taken with special measuring equipment or from civilian police vehicles. Based on video recordings, a so-called distance/time analysis is used to calculate how much distance there was between the vehicles. Critical: It is usually the smallest distance measured that counts, not the average driving behavior. Particularly problematic: Even cell phone recordings can be sufficient if the analysis is carried out correctly.
Even a few seconds below the permitted value will result in a penalty notice and withdrawal of the driver’s license.
How much distance is “too little distance”?
Two rules of thumb have become established in practice and case law:
- “Half speedometer rule”: The distance in meters should correspond to at least half the speed in km/h. This corresponds to a time interval of 1.8 seconds.
- “Two-second rule”: The time gap to the vehicle in front should be at least two seconds.
If the distance is too short, there are always two proceedings: A distinction must be made between the criminal qualification by the public prosecutor’s office (simple or gross violation of traffic regulations) and the administrative qualification by the road traffic authority (minor, moderate or serious violation). Under criminal law, a fine, fine or custodial sentence may be imposed. Administratively, a driver’s license may be withdrawn – for at least three months in the case of serious violations.
Distance in seconds | Criminal law qualification | Qualification under administrative measures law |
< 0.3 seconds | Qualified gross violation of traffic regulations (speeding offense) | As a rule, precautionary driving disqualification with an order for a traffic psychologist’s report |
< 0.6 seconds | As a rule, gross violation of traffic regulations | As a rule, serious offense → at least 3 months driving disqualification |
0.6-1.2 seconds | Simple or gross violation of traffic regulations (depending on the circumstances) | As a rule, moderate or minor offense (depending on the circumstances) → at least 1 month withdrawal |
over 1.2 but <1.8 seconds | Partly simple traffic rule violation | Partial minor offense → warning or at least 1 month if ID card has already been withdrawn in the previous two years |
Important: In its leading decision BGE 131 IV 133, the Federal Supreme Court clarified that an overall assessment of the circumstances of the individual case is always decisive for the qualification. In particularly unfavorable conditions (poor visibility, wet conditions, heavy traffic), even a smaller distance violation can lead to a stricter assessment.
Conclusion
There is a fine line between everyday behavior and breaking the law. What many consider to be a harmless gesture in the overtaking lane becomes grounds for disqualification in the measurement protocol. In the interests of fairness, unnecessary driving on the left should also be punished more consistently – because it is often the cause of dangerous situations.
If you are affected, you should not simply wait and see, but should actively clarify at an early stage whether the measurement is correct. This is the only way to protect your rights.
