Rear Bike Rack Loading Mistake: When Does It Become a Fineable Offence?
In Germany, rear bike racks (Fahrradträger) are widely used, especially for trips and holidays.
But many drivers don’t realise that loading a bike incorrectly—so that it covers the rear lights or the licence plate (Kennzeichen)—is a traffic offence that can lead to fines and even penalty points, especially if repeated or if damage occurs.
What are the legal rules for carrying a bike on the rear?
According to § 49a StVZO (Germany’s vehicle technical regulations), the driver must ensure:
the rear lights remain fully visible and clearly recognisable
the licence plate (Kennzeichen) is uncovered and clearly readable
the rear overhang does not exceed 1.5 metres (including the bike and the rack)
If any of these elements are covered, the offence applies—even if it was not intentional.
What penalties can be expected?
| Type of offence | Fine | Points in Flensburg | Notes |
|---|---|---|---|
| Rear lights covered or not properly visible | €20–€40 | No | Depending on severity |
| Licence plate (Kennzeichen) fully covered | €60 | 1 point | Affects vehicle identification |
| Load not properly secured and may fall | Up to €75 | 1 point | Safety risk |
| Accident caused by incorrect mounting | Fine + compensation | 1–2 points | May lead to criminal proceedings if damage occurs |
Can cameras detect the offence?
Yes. Covering the licence plate can be detected by automatic number plate recognition systems (Kennzeichenerkennung) in paid parking areas, at barriers/toll points, or via traffic cameras.
If the camera cannot read the plate because of the bike, this may be automatically recorded as a violation.
Real-life cases
In 2023, a driver in Baden-Württemberg was stopped because the mounted bike completely blocked the left rear light.
The outcome:
€40 fine
Official warning in case of repetition
Requirement to re-mount the bike correctly on the spot
Tips to avoid violations
Use racks with integrated additional lights and a separate licence plate holder mounted on the rack
Make sure the bike does not exceed the vehicle’s width in an impermissible way
Check the rear view before departure at night: are the lights fully visible?
Secure the bike properly with straps so it cannot move while driving
Conclusion
What seems like a “small detail” on your trip can turn into an official violation and penalty if the bike is mounted incorrectly.
Covering lights or the licence plate is not just a mounting mistake—it is a real traffic safety issue.
In Germany, careful loading means safety… and avoiding fines.
