Have you Noticed the Red Lines at the Back of Trucks?

When driving around Spain, have you ever noticed that most trucks have red lines at the back, usually following the frame of the doors, or circular on tankers? Well, these lines are not just to make it look pretty, they serve a very clear safety role, and they are mandatory.

The lines, or stripes, have been mandatory in Spain since the end of 2024, and draw an outline around the truck, so as to make it more visible, as they are also reflective so highlight the presence, size, and gauge of the vehicle during poor visibility episodes, such as at night, and they also serve as an indicator as to the characteristics of the truck for those approaching.

These lines are technically a road sign, with the official catalogue number of V-23, and is not only present on the rear, but also required on the sides.

The V-23 sign is a key reflective device for improving road safety, especially in low-visibility conditions. According to the General Vehicle Regulations, the V-23 sign is a reflective adhesive tape placed on the rear and side contours of transport vehicles. Its main function is to ensure that these vehicles are visible from any angle at night or in adverse weather conditions.

According to Royal Decree 1030/2022, for all vehicles with a maximum weight exceeding 7.5 tonnes and measuring more than six metres long and 2.1 metres wide, as well as trailers and semi-trailers with a maximum weight exceeding 3.5 tonnes, registered after July 10, 2011 and before 20 December 2022.

For vehicles registered before 2011, the installation of the V-23 marking is voluntary, but recommended to improve visibility and safety.
