The most important rules for transport with a rear bike rack within the EU
During the holiday season, rear-mounted bike racks are popular companions to easily transport your own bikes. Depending on where you go on vacation, different rules than in Germany apply to this transport.
In Germany, for example, a third license plate must be used if the carrier covers the license plate on the vehicle. In addition, the carrier may protrude a maximum of 150 cm at the back and the bicycles may protrude a maximum of 20 cm on the sides. Special labeling for the bicycle racks and/or their load is not required in Germany. However, any lamps that may be hidden on the vehicle must work on the rear bike carrier.
It’s similar in Austria too: In Germany we are allowed to protrude 20 cm on the sides of bicycles. If the license plate is not readable and is covered up, a third license plate must be used. If taillights and reflectors are used, it is mandatory to use a light bar.
Rules for rear bike racks in Belgium and the Netherlands
In Belgium it is a little different, where the width of the vehicle with a bike rack cannot exceed a total of 255 cm. In addition, the vehicle’s license plate and lighting must be fully visible; if this is not the case, both a separate lighting bar and a third license plate are required. What is also special is that a bicycle rack with its own rear fog light is also required for vehicles with a Belgian license plate.
In the Netherlands, bicycles are also allowed to protrude 20 cm, so the maximum width is 255 cm. The rear bike carrier may protrude a maximum of one meter to the rear. A third license plate and extra lighting must be used if this is obscured by the use of the rack on the vehicle. As in Germany, special labeling of the rear bicycle carrier is not required.
Rear bike rack in southern Europe
In Italy, bicycles may protrude a maximum of 30 cm on each side when transported; a red and white marking board is also mandatory there. This must have dimensions of 50×50 cm. We have summarized all the information about this in a separate blog post. When it comes to the license plate and the lighting, in Italy you have to remember that both have to be fully visible. If this is not guaranteed, you will have to use a separate light bar and a third license plate.
Also in Spain, light bars and the third license plate are required under the same conditions. In addition, a square, red and white striped sign measuring 50×50 cm is mandatory there, even if there are no bicycles loaded on the rack.
In Spain’s neighboring country Portugal, it is initially advised to transport bicycles on the roof with a roof rack. If a rear bike carrier is used, the carrier and the bicycles must not be wider than the car. It must also be proven that the carrier is approved for the transport of bicycles and that the carrier is demonstrably suitable for transport. At the rear, the rear bike rack is only allowed to protrude 45 cm, which is significantly less than in all other countries. Important to know: For carriers that are mounted on the towbar, this is measured from the trailer hitch. In addition, in Portugal the necessary measures apply if the license plate and lighting are obscured (use of third license plate and light bar). The warning sign is also mandatory.
Regulations in Northern Europe
In Northern Ireland the regulations are quite simple, bikes are only allowed to protrude a maximum of 30.5cm on each side. If the license plate is covered, it must be replaced by a third license plate; the same applies to the lighting.
In Sweden, bicycles are only allowed to protrude a maximum of 20 cm on each side and a third license plate must always be attached. The lighting must also be fully visible, otherwise a light bar is required. There are also country stickers.
