The Foreign Office offers the following advice:
If you hire a moped (for Phuket read motorcycle) or quad bike, check the small print of your travel insurance to make sure you are covered and always wear a helmet
Remember most insurers won't pay out if you injure yourself or others when you've been drinking alcohol - check your small print.
The British Ambassador to Thailand, Asif Ahmad, said: ''Thailand rightly remains an attractive tourist destination and a significant number of people have chosen to become long-term residents.
''Good planning is the best way to avoid hazards and insurance for travel and health is essential. Medical bills can run to thousands of pounds and the British tax payer cannot meet the uninsured costs of fellow citizens who have chosen to venture abroad.
''Make sure you read the small print - riding a motorbike or other activities could invalidate the insurance policy . . . We do recommend travellers check health requirements to ensure they've had all the necessary vaccinations.''
