The overtaking of trucks on the highway

Driving quietly on the highway at 130km / h, you are brutally blocked by a truck that doubles at 90km / h ... annoying, is not it? But is it forbidden?

To my knowledge, these trucks can be sanctioned in two very special cases only ... the rest of overtaking are certainly embarrassing, but not prohibited.

Lanes of at least 3 lanes

The principle

If you are on a lane of at least three lanes (ie 2 × 3 lanes or more), there is a special rule concerning the use of lanes by heavy goods vehicles.

In fact, for heavy vehicles over 3.5t or over 7m in length, they are forbidden to use other routes. than the two most right lanes (R412-25 of the Highway Code):

When a road has three or more lanes, assigned to the same traffic direction, drivers of vehicles whose total authorized laden weight exceeds 3.5 tonnes or of a combination of vehicles whose length exceeds 7 meters are prohibited '' take other lanes than the two lanes closest to the right edge of the road, except, as little as possible to prevent the normal running of other vehicles, to prepare for a change of direction.

To put it simply, heavy goods vehicles can use the routes indicated in this diagram:

Failure to comply with this rule may result in a fine

The really slow heavyweights…


When overtaking, heavy vehicles must be careful not to slow down other vehicles too much (in reality, this is also true for all vehicles).

Thus, when a vehicle uses the left-most lane, it must not be below 80 km / h (R413-19 of the Highway Traffic Act).

As a reminder, there is no minimum speed on the motorway, but your speed must not, in any case, " interfere with the normal operation of other vehicles while driving for no good reason at an abnormally reduced speed »(R413-19 of the Highway Traffic Act).

Driving under the 80km / h threshold on the leftmost lane is punished by a 2nd category fine of 150 € (R413-19 of the Highway Traffic Act together R131-13 penal code).


  1. hello, I just do 1450 kms on the highway and I find that there is very little, yes I say trés, very few accidents on the French motorways when we see the intense traffic and especially the risks that heavy vehicles take !!!!!! it is absolutely scandalous to repress so much in order to penalize the motorists and to do nothing to supervise the driving of these truck drivers ... of course, not all but especially all these immense trucks which take the aspiration of the previous one so to start doubling, which put their flashing and deporting to pass in front of & ptct; #8230; this is a scandal and all these truckers are foreign most of them & #8230; & #8230; and what are the authorities doing to put a brake on these abuses ?? nothing & #8230; .. ON PENALIZE CARS THAT ROLL TO 140 BUT WHO ARE 2TUDIEES AND CAPABLE OF ROLLING TO 180/200 BUT WE SAY NOTHING TO ALL THOSE TRUCKS THAT ROLL 100/110 BUT ARE AT THEIR LIMITS OF POWER ??? ?????

  2. Hello

    What about two-lane highways (Toulouse Narbonne for example & #8230 ;.) where we see regularly on the path of the panels "trucks forbidden to double" but where we often miss getting into a truck that debunks to overtake another truck (express passage from 130 km / h to max 80 & #8230; grrr! i hate !!!)
    My question: do they really have the right to double then? What are the signs "trucks forbidden to overtake" otherwise? (or how many km are these signs valid? ??? !!!)

  3. Do trucks have the right to dock without worrying about vehicles?
