Be wearing a helmet if driving a motorbike, moped, scooter, or assisted bicycle.
Be wearing a seatbelt when travelling in a motorised vehicle where a seatbelt is available for use.
You'll need to hold a full licence. A provisional licence or a CBT won't be accepted outside the UK.
Just because you're entitled to drive a vehicle in the UK does not mean you'll be able to do so in another country, as their minimum age or licencing requirements may vary.
Many rental companies have minimum age limits for rental; in particular, it is common in many countries that you'll be unable to rent or charged a surcharge if you're aged under 25.
Some countries and rental companies require you to have held your licence for a minimum number of years to be valid to rent a vehicle.
Many countries accept a UK driving licence without further documentation; some, however, require you to have an international driving permit (IDP), see https://www.gov.uk/driving-abroad/international-driving-permit for more details.
Some countries will require you to provide a licence ‘check code'; see https://www.gov.uk/view-driving-licence for more details.
It's important you understand the rules of the country you are intending to drive in; they can vary significantly, and sometimes the rules aren't ones that you'd guess. For example, did you know it's illegal to drive in flip flops in France and Spain or without a shirt in Thailand, legal to turn right on a red light in the USA and Canada, and illegal to eat or drink anything while driving in Cyprus!
