Driving on the right is very easy once one gets used to it and I wonder why we do not do it here in UK, big logistic I know, if you have a sat nav , set it to remind you that you have to drive on the right, especially as you exit places like Supermarkets as that is when it is easy to forget, it seems so natural to go right round roundabouts, keep to the right on roundabouts even if you are going right round to the last exit, keep your left indicator going ,until your exit then signal right, do this until you feel that you can hug the roundabout,till your exit, you will find that Johnny Foreigner does pretty much what he wants when driving but overall I think the standard of driving is good over there?be aware that vehicles are joining your road from the right so keep a good look out for this when on faster roads , DO NOT flash your lights as a give way sign, Johnny Foreigner does not understand this generally, , a flash of your lights over there means LOOK I AM HERE , and just causes confusion,a lot of horn blowing is done , best to ignore this as it usually means nothing .Traffic lights do not generally have an Amber just green and red, there is usually a small light on the traffic light pole lower down from the main lights so that you can see what light is on if you are too close to the traffic light, if you are turning right at a traffic light and it is RED, there is often an Amber flashing arrow on the light , this says that you can turn right against a RED light if it is safe to do this,Be aware that the speed limit in all towns ,villages and cities is 50 kmp [30 mph ] even if NOT signed ] FRANCE but also Spain etc so be aware of this, there are also traffic lights that turn RED as you approach if you are driving too fast, or if someone coming the other way is driving too fast, this is just to control speed and is a great idea I think.
When driving in uk it is the norm to stay in the left hand lane on roads, over the Channel just stay in the right lane until you are happy to start changing lanes , when exiting a junction and joining a road such as a T junction you will be looking RIGHT watching traffic BE AWARE that this traffic on your right in the opposite carriageway is COMING TOWARD you and not away as would be the case in the UK, the traffic on your left is ALSO coming TOWARD you TOO in the carriageway you are about to cross.sounds confusing but it is all easy just take your time double think your moves and you will be OK.
