France Introduces new red lines on certain roads to discourage dangerous overtaking. If you read this article you'll have a better understanding of what UK drivers need to know when touring on French roads.
British drivers hitting the roads in France may notice a new feature on certain roads: red lines running down the centre of the road in areas prone to accidents.
These bold red markings, recently introduced on stretches of the A7 near Lyon and the A10 towards Bordeaux, are part of an experimental safety measure aimed at discouraging overtaking in high-risk areas with reduced visibility or sharp bends.

What Do These Red Lines Mean?
For those accustomed to traditional white or yellow lines marking no-overtake zones, the red lines serve a similar function but are designed to be far more noticeable. They’re placed where conditions require extra caution, like near motorway exits, in construction zones, and on stretches with complex intersections where errors in judgment can be dangerous.
Much like a continuous white line in the UK or a double yellow line in the US, the red line prohibits overtaking. By using the highly visible colour red, French authorities hope to alert drivers to potential danger, encouraging them to slow down and stay in their lane.
Why Is This Important for British Tourists?
Many British tourists may not be aware of this new measure, which differs from road markings they’re used to. Missing these red lines and overtaking in prohibited areas could lead to fines and penalties. A single violation can result in a €135 fine and the loss of three points from a driving license.
There are many things that can land you with an on-the-spot fine while driving in France, so you should read our Driving in France Checklist, for full details.
The fines in France are comparable, maybe even slightly less, than the fines issued in Spain. Spanish police have been pretty strict on this. They have tested red lines in Spain for a while, and fines there can be over €200, with the possibility of a driving ban for up to three months.
My Opinion
I've not experienced too many problems with crazy drivers whilst in France, but my parents lived in Spain for over 20 years and I've driven to their villa there many times. I must say the level of dangerous overtaking in Spain used to scare the life out of me sometimes.
So if these red lines work then I'd be all for them.
France’s Broader Strategy for Road Safety
This initiative reflects France’s ongoing effort to reduce road fatalities, which amounted to over 3,000 in 2023. Inspired by similar measures in Spain, the French government hopes that these red lines will make dangerous areas more obvious, prompting drivers to take extra care.
If this pilot program proves successful, these red lines could become a common feature on other accident prone roads throughout France.
For British tourists unfamiliar with these new markings, it’s essential to stay vigilant and understand that crossing these red lines could carry serious consequences. Be mindful of these changes and stay alert to help ensure a safer driving experience while exploring France.
