How to make myself more visible in traffic as an EU mainland driver in the UK?

I'm going to take issue with Dan North's accepted answer, not that it is bad, but let me put my own perspective on it. I am a Canadian, but spent most of my life in Scotland, learned to drive there and did for nearly 30 years before returning to Canada a few months ago. During this time I also did regular (2-3 times a year) multi-week driving stints on holidays in Europe (France, Spain, Greece), so hope to have some insight.

Driving on the opposite side ISN'T THAT HARD (takes me about 30 secs to re-orientate after doing it for years). Yes the first hour or so on your first ever drive on the other side is pretty scary (ironically I found it best to start on a big motorway where you could cruise and get your bearings, small roads in town are much harder).

The thing for you coming from Europe is that the roads behave in a similar way - signs are similar if not identical, motorway lanes are more familiar, you'll be used to how roundabouts work etc. I found driving in Canada much more of a shift - right turns on red, left filter signals, 4 ways stops rather than roundabouts, motorway free-for-alls with people just ignoring speed limits (fun to be doing 15 over the speed limit in the middle lane on a big highway and have 10 cars undertake you at a much higher speed), different words on some signs.

This brings me to my issue on using a P plate. Drivers in Scotland are not forgiving, you can see them venting frustrations as they have to overtake learners in branded driving school cars (that can be recognised half a mile away), and the feeling I suggest would be as a P plate (even a pretend one), you are supposed to know how it all works and get on with it. New drivers I've known have discarded P plates in a few days as they felt less pressure without one.

To me the biggest hurdle will actually be your LHD car. One of the cues for my brain (at least in Europe) is changing gear with the opposite hand (so not done by muscle memory). I would find driving on the "wrong" side of the road in my normal car very disorientating, especially at roundabouts, and I would hazard getting a right hand drive car would make things much easier to acclimatise.

I would additionally suggest getting the LHD car registered in the UK will be difficult. You'll need very good evidence of the age of the car to avoid getting a Q plate which will make the car much more expensive to insure and harder to sell (cars in the UK are more identified by number-plate rather than VIN, and have digits showing the age, cars of unknown or questionable age get a Q reg). You'll need to get the UK reg to get insurance for the car in the UK, and you'll find at sale time most dealers won't touch a LHD with a 10 foot pole.

So I would just ditch the LHD car, buy a UK one (yes it will likely be older as I'm assuming you are bringing it to offset the high price of vehicles in the UK, it isn't some classic Bugatti), and a couple of good runs will bring you the confidence you need, the more you make issue of it being different (by sticking in the LHD), the longer it'll take to acclimatise.

So in summary, my answer is Don't make yourself more visible, you'll be better treated, and get used to driving in Scotland much better by getting a UK car and blending in.

Put an oval country bumper sticker on your car.

Use a white one with the code of your country (which is not a secret anyway because of your license plate), not a "generic European" one with a circle of stars, because that could be confused for an anti-Brexit statement.

You can also use a sticker like this:

It can be found at online stores, like eBay.

I learned to drive in the Netherlands and then moved to the UK with a Dutch car. It took me less than a day to get into the habit of driving on British roads and whilst I did have to be more careful on lonely country roads, in the dark after a long, tiring day (when it's easy to make mistakes such as driving on the wrong side of the road for a while), I never had any incidents.

That said, I wouldn't recommend bringing a LHD car to the UK, unless you're only doing so for a limited time:

• You will be less safe driving an LHD car in the UK due to reduced visibility (overtaking and exiting into traffic is more difficult)
• You'll need to import your car, which is a hassle and expensive
• You'll need to pay more for insurance once you're on the UK plates
• You'll sell your car for much less than you could at home since local buyers won't want an LHD car unless it's a pretty unique/collectable one.

Getting used to driving on the other side of the road won't be the difficulty, the other issues will be in the long-term.

Don't worry about it. If you are in the rural parts of Scotland, motorists are used to tourists driving relatively slowly, especially away from the main roads. Erratic driving (e.g. tourists suddenly braking because they nearly missed a turning, and not indicating they were going to turn) is more annoying and dangerous than people who are just driving a bit slower than "average" while giving clear signs of their intentions.

In towns with speed limits and more traffic, you will very quickly learn to "keep up with the traffic flow" anyway.

Your biggest problem with a LHD drive car will be overtaking other slow moving or parked vehicles on relatively narrow roads. Just learn to keep a bit further back and drive closer to the centre line of the road, so you have a better view past them.

Let's be clear, though. Safety isn't about which side of the car you sit on.

Safety is about placing safety ahead of every other priority, including road rage, ingrained habits, testosterone displays, playing with your phone, not missing your turn (let yourself miss your turn! And recover), everything else.

It's about having a love-of-craft toward safety, a desire to learn, to critically examine ones own driving for opportunities to improve, maybe even reading accident reports to see where others go wrong.

Developing confidence that your driving is good so you aren't flustered.

Last but not least it's about putting your full attention on what you are doing.

If you have those things, you could drive backwards and you'd be fine.

Being Dutch, I used to work and live in the UK a couple of years. If you're a confident driver, there's nothing to worry about.
I took the ferry from IJmuiden to Newcastle, drove around a couple of months on Dutch license plates, applied for UK registration and only had to pass the MOT.
Plus was that driving on foreign license plates, I would not get any tickets for speeding ;)
You have to adapt your mirroring a bit and look over the "wrong" shoulder but you'll get used to that pretty easily.
One piece of advice, do adjust your headlights as right now they're beaming in the wrong direction.
