France - Liber-t tag
As long as your vehicle is no more than 3 metres in height and less than 3.5 tonnes GVW you can use any non height restricted lane that has the Liber-t symbol illuminated. A vehicle of this size falls into the Class 2 fee structure. If your vehicle is larger than this then please contact our sister company Eurotoll.

Can you help me out on this one please ?

As far as I understand the Toll Tags you get to use in France are identical regardless of the height of your Motorhome.

So any Tag should lift the barrier as you approach regardless of the Motorhome height but they will charge you the appropriate price for your vehicle as Class 2 or Class 3 depending on height.

Someone on another Forum has been having problems, the first time abroad with a Tag, with the barrier sometimes lifting and sometimes remaining down and a Forum Member's reply says that there are different Tags for different Classes and that is the reason for the problem.

I don't believe that's the case and for the majority of normal Motorhomes the Tag we use covers those under 3 metres high and those over 3 metres high and charges us accordingly.

I think the person having problems either has the Tag in the wrong place, the battery is not working correctly or he isn't getting close enough to the barrier.

Any useful input about the situation appreciated.

Yes Jean. It now encompasses Portugal and Italy.
My referral commission is only €4. I did get one I think from Andy so I am €4 in credit.
