After some heavy snowfall in the last few weeks, if you are driving to the French Alps for your ski holiday make sure you are prepared with the necessary equipment. Snow chains are easy to put on and may be a crucial requirement in order for you to reach the mountain resort.

Are snow chains a legal requirement in France?

Technically snow chains are not always compulsory by law in France. However on certain roads after large amounts of snowfall, Police/Gendarmerie will often stand at the bottom of these roads to prevent any vehicle without special equipment from going any further.

How will I know when to put them on?

Whenever you are required to use snow chains, there will be signs to alert you to do so present on pretty much all of the mountain roads in the Alps that look a little like this:


Will every vehicle need snow chains?

Even if you are driving a 4x4 vehicle, chains will still be required in certain circumstances so the advice is to always keep a pair in the boot. Snow chains are like insurance, you probably won’t need to use them and with insight you may feel it was a waste of money, but when you do require them you are glad you have them in the car!

Will I need to use snow chains if I already have snow tyres?

Cars equipped with snow tyres will only need to add chains if snow is very deep and has not been cleared (eg. getting out of a steep driveway), or if the roads have completely iced over.


How likely is it that I will have to use them?

95% of the time you won’t need to use them. If you are amongst the 5% that does (most likely when driving out of your parking spot in resort) then you will be glad you have them.

How easy is it to fit snow chains?

It’s a common misconception that snow chains are difficult to install, but this short video shows you just how easy fitting snow chains can be:


Step One

Your car will be either front or rear wheel drive – prepare to install your chains on the drive wheels.

  • For traction cables, check for broken cables or links

Step Two

Drive about a foot onto the chains. Next drape the chains over the tire and fully engage the knob in the fastener.

  • At this point the ends of the connector cables should be on the outside of the tire
  • Make sure the cross-member cables are centred over the tire tread
  • To make it easier, turn the wheel

Step Three

Secure the cable on the inner sidewall. Pull the cable ends with knobs, up to the keyhole latch then secure the cable slack with the “S” shaped plastic fastener.

  • If the cables are too loose, pull some slack out of the chains

Things to Note 

  • Tire sizes vary so check for the proper fitment before you use your chains
  • After installing, drive about half a mile and recheck the installation
  • Always accelerate slowly and evenly
  • Do not exceed 30mph
  • Do not spin the tires
  • Do not lock the wheels when braking
  • Do not drive on pavement that’s not covered with ice or snow
