Car tax in france?

off to france for the day and tax runs out the day before we get paid and go on the trip, so on the day we cant get the tax because we will be leaving too early does anyone know what the tax laws are in calais as we are taking the car for a day trip there on eurotunnel many thanks

Why would foreign authorities care about the fact that you haven't renewed your British car tax? You'd only be in trouble in the UK, not in France.

The French police enforce French laws, not English ones, and would have no idea what this car tax is that you are talking about. So you needn't worry, at least not on the French side of the Tunnel.

the french abolished the tax on cars 3 or 4 years ago it was called the vignette.you only have to display in your screen a valid mot and insurance if you live in france

Don't worry, it's free in France, the French government stopped taxing vehicles few years' ago, but then you have to pay motorway toll, it's called autoroute p茅age.
Anyway, the Gendemarie very rarely check and stop foreign cars, especially one marked GB.

don't know what you're talking about .....

you've got car tax when you live in france, not when you're tourist.
are you talking about "p茅age autoroutier" ? it's what you pay when you use some highway....

If you do not have a valid tax-disc on your car means that your insurance is invalid whatever country you are in so you will be driving illegally.

You will not get into trouble in France for not having your tax disc, but you may get into trouble when you return to the UK, either because someone spots it (unlikely) or because the DVLA computer spots that it hasn't been renewed. If payment is the issue, I would suggest that you go to a post office the day before and pay for your tax disc using a cheque, as this will not hit your bank account until after you have been paid. You can renew your tax disc up to 2 weeks before it expires.

I would worry more because your car insurance will be invalid. If you had a prang, and claimed on your insurance, they would reject the claim because you hadn't complied with the law .... and then you could be prosecuted for driving without insurance!
You can buy car tax on line at the DVLA website.

France is a lawless country so it shouldn't be a problem.
