🚛 What is a long vehicle
A long vehicle refers to any single vehicle or combination (tractor + semi-trailer, articulated bus, heavy truck) that exceeds the standard legal length allowed for its type under European traffic law.
According to EU Directive 96/53/EC and national traffic codes, a long vehicle is:
-
a single vehicle over 12 meters long;
-
or a vehicle combination exceeding 16.5–18.75 meters, depending on its configuration.
📏 Common examples
-
Articulated buses (up to 18 m)
-
Heavy trucks with semi-trailers
-
Tractor–trailer road trains
-
Oversized convoys (over 19 m, require permit)
These vehicles must be clearly marked with a yellow “LONG VEHICLE” sign and equipped with reflective strips for visibility.
🚦 Signage and safety
Long vehicles must:
-
display reflective warning plates at the rear;
-
maintain greater following distances;

avoid routes marked with “No long vehicles” restrictions.
For oversized or special transport, an escort and special authorization are mandatory to ensure road safety.
