In France, driving in mountainous regions during winter requires specific preparation to ensure safety and compliance with the law. Snow chains provide essential grip on heavily snow-packed roads, but using them is governed by strict traffic regulations, including the 'Loi Montagne II'. Knowing how to identify the mandatory snow chain sign (B26) and when to mount them is a key topic on the French Code de la Route theory exam.
Chaînes à neige
Snow chains are temporary metal links wrapped around drive wheels to maximize tire traction on heavily snow-covered or icy roads.
Chain the DRIVE to stay alive: Always mount snow chains on the DRIVE wheels to maintain traction on snowy mountain climbs.
Quickly understand the most important facts, rules, and meanings related to Snow Chains in French driving theory for France. This focused summary helps learners revise key terminology, traffic concepts, and exam-relevant knowledge efficiently.
See how Snow Chains appears in realistic driving situations relevant to France. These examples explain correct behaviour, safety implications, and how Snow Chains connects to French driving theory exam questions.
You are approaching a mountain road covered in heavy snow and pass the blue circular B26 sign.
Pull over safely in a designated chain-mounting area (aire de chaînage) and install the snow chains on at least two drive wheels before continuing.
Sign B26 makes snow chains mandatory on snow-covered roads to prevent vehicles from losing traction, sliding, or blocking mountain passes.
After crossing a snowy mountain pass with snow chains fitted, you pass sign B44 and the road is now completely clear and dry.
Pull over safely in a designated parking or stopping area to remove the snow chains before continuing on the dry tarmac.
Sign B44 signals the end of the mandatory snow chain zone. Driving on dry tarmac with chains damages the road surface, ruins your tires, and severely degrades vehicle handling.
You are driving through a department in the French Alps during the winter regulation period (November 1 to March 31) under the 'Loi Montagne II' rules, but the weather is clear and sunny.
Ensure you have a set of removable non-skid devices (like snow chains or snow socks) in your boot, or ensure your vehicle is fitted with four winter tires marked with 3PMSF.
The Mountain Law makes winter equipment mandatory in designated zones during the winter period regardless of the immediate weather conditions on that day.
Learn the legal requirements for using snow chains in mountainous zones under French law, including speed limits, mounting locations, and road signs.

Get clear answers to the most searched questions about Snow Chains in French driving theory for France. This FAQ explains the definition, real exam context, practical meaning, and common learner doubts to support confident theory test preparation.
Snow chains must be mounted on at least the two drive wheels (the wheels that receive power from the engine). For front-wheel-drive cars, mount them on the front tires; for rear-wheel-drive cars, mount them on the rear tires. On four-wheel-drive (4WD) vehicles, it is highly recommended to equip all four wheels or follow the manufacturer guidelines.
Driving with snow chains severely limits your vehicle's speed and handling. In France, it is strongly recommended not to exceed 30 to 50 km/h when chains are fitted, as higher speeds can break the chains and damage your car's suspension or bodywork.
The circular blue sign B26 indicates that snow chains are mandatory on the road ahead. The sign B44, which features the same symbol crossed out with a red diagonal line, indicates the end of this obligation, meaning you should safely remove the chains when the road is clear.
The 'Loi Montagne II' is a French regulation requiring drivers in 34 mountainous departments to equip their vehicles with winter tires or carry removable non-skid devices (like snow chains or socks) in their trunk from November 1 to March 31, ensuring readiness for sudden snowfall.
Yes, in France, high-quality textile 'snow socks' are legally recognized as removable non-skid devices, provided they are certified. However, classic metal snow chains are still preferred for deep snow, steep slopes, and long-distance winter driving due to their superior durability.

Obtaining a French driving license involves more than just passing the theory and practical tests; it requires a structured learning approach. This article breaks down the official minimum driving lesson requirements for the permis B in France, exploring both the mandatory hours and what is typically recommended by driving schools (auto-écoles) for success. Learn how to navigate your training effectively.
Zonal signs are used when a rule applies to more than one point or street, such as parking controls, speed zones, pedestrian areas, home zones, restricted access areas, or winter-equipment zones. The sign tells drivers to remember the rule even when it is not repeated on every side street. Safe driving means adapting speed, access, stopping, or equipment from the zone entry until the signed exit. Official French sign code: B58.
