Just a note about 'L' plates. They are really only for learner drivers, that is those who do not have a full licence. There are various regulations surrounding learner drivers, such as the fact that they cannot drive alone (obviously) and have to be supervised by someone over 21. Learner drivers can only drive on motorways if the car is fitted with dual controls and they are accompanied by a driving instructor. You could get stopped by the police if you appear to be a learner (I.e. you have an L plate) and you are breaking any of the regulations applying to learner drivers. While you will probably be able to prove you're not really a learner, it could be a bit of a hassle. So I'd actually recommend getting a 'P' plate rather than an 'L' plate. P stands for probationer or new driver and just shows other road users that you are a less experienced driver. P plates are not mandatory, so there are no regulations surrounding their use. You can buy them in all the same places as L plates, e.g. really big supermarkets or hardware stores, or shops specialising in car equipment - the chain Halfords have a branch in most large towns, often on the retail parks on the edge of town.
Here is a link to the UK Highway code that is essential reading before driving here. Highway Code The Highway Code does say you should remove your L plates when you have passed your driving test.
Hope this helps.
