Angles Morts sticker – where is it required and what does it mean?

Have you ever noticed stickers with the phrase “Angles Morts” placed on certain trucks?

You might be wondering what they mean and whether they are mandatory. In this article, we will clarify their purpose, explain why they are important, where to purchase them, and in which situations they are required.

What is Angles Morts?

Angles morts is a French term meaning “blind spots”. In transport terminology, it refers to areas around a vehicle that remain invisible to the driver, even when using side mirrors.

This issue is particularly significant for large vehicles such as trucks, buses, and specialized vehicles, which have substantially larger blind spots than passenger cars due to their design.

These invisible zones can create dangerous situations, as a driver may be unaware of the presence of other road users — such as pedestrians, cyclists, or smaller vehicles — leading to potential accidents.

The importance of the Angles Morts sticker for other road users

The Angles Morts sticker serves as a warning to other road users about the blind spots surrounding a large vehicle. It informs pedestrians, cyclists, and drivers of smaller vehicles about potential dangers caused by limited visibility — encouraging them to exercise extra caution when near large trucks or buses.

Mandatory use of the Angles Morts sticker in France

Since January 1, 2021, France has enforced the mandatory placement of Angles Morts stickers on all vehicles with a Gross Vehicle Weight Rating (GVWR) exceeding 3.5 tons. This applies to both goods transport vehicles and passenger transport vehicles, including trucks, buses, and coaches.

It is important to note that this requirement applies to all vehicles exceeding 3.5 tons operating on French roads, regardless of their country of registration. This means that both domestic and foreign trucks and buses traveling in France must display the Angles Morts sticker.

Placement requirements for the Angles Morts sticker

To ensure the sticker effectively serves its purpose, its placement on the vehicle must comply with specific regulations. These requirements are designed to minimize accident risks and increase awareness of the dangers associated with blind spots.

Proper sticker positioning (a total of five stickers) is not only a legal obligation but also a key factor in improving road safety.

Tractor Unit Sides

Two stickers must be placed on both sides of the tractor unit — one on each side. They must be positioned in a clearly visible area, without covering essential vehicle elements such as lights or identification plates. Each sticker must be located within the first meter from the front of the vehicle.

Trailer Sides

Another two stickers must be placed on both sides of the trailer. Their placement is strictly regulated:

• They must be positioned no further than 1 meter from the front of the trailer.
• They must be installed at a height between 0.9 meters and 1.5 meters above the ground.

Rear of the Trailer

One additional warning sticker must be placed on the rear of the vehicle at a height of 0.9 meters to 1.5 meters from the ground. It must be positioned in a clearly visible area for other road users.

The correct term is “Angles Morts”, which means “blind spots” in French. A common mistake, “Angels Morts”, likely comes from its similarity to the English word “angels”.
