Whenever I drive in France I have to change more than the side of the road.
In the UK we drive on the left. At roundabouts traffic already on the roundabout, or coming from my right, has priority.
In France they drive on the right. But at roundabouts traffic coming from my right STILL has priority. Unless otherwise stated by road sign, ALL traffic coming from my right has priority even if it is a tractor coming out of a farm track on to a main road.
On Autoroutes, the French equivalent of UK motorways and US freeways, traffic MUST keep to the right hand lane at all times unless actually overtaking another vehicle. So drivers pull out to the left to overtake, pull back to the right as soon as they can, and out to the left to pass the next vehicle, repeating this several times in a kilometre if there are several slow vehicles in the right hand lane. In the UK to pass three slower vehicles I would stay in the fast lane until I had passed all three.
Speed limits are in kilometres per hour. If you pass a town or village sign, unless there is a speed sign mandating a higher limit, the speed limit is 30 kilometres per hour until you pass the same town or village sign with a red line across it to show the end of the community. 30 kph seems very slow, but do 35 and you'll get a ticket to be paid in cash on the spot. No cash? Your vehicle is seized and you are dumped at the roadside.
Also in France you have to have:
A fire extinguisher
Enough hi-vis jackets inside the car, not in the trunk, for the driver and passengers.
A First Aid kit
At least two breathalyser test devices. If the police ask you to demonstrate that you are not alcohol impaired you must still have another breathalyser.
A warning triangle
Spare bulbs for all driving lights and the knowledge to fit them.
In other European countries the requirements vary.
Almost like driving in Canada yet they still drive to the right side of the highways.
They prefer doing stuff in metric.
