United States Embassy in Bucharest, Romania
Bucharest has cheap and plentiful public transport provided by underground, bus, and tram. Yellow taxis are also abundant but make sure prices are listed on the side of the vehicle and that the taxi bears a company name. There are frequent reports of foreign visitors being overcharged by taxi drivers. Other cities have fairly good bus services. Cities and towns are linked by extensive but generally slow rail services.
If travelling on a domestic air flight, have your passport ready for inspection at all times. If you are driving to Romania, you are required to pay a road toll to allow you to use the national roads. Tolls are charged on motorways and main roads out of town, payable in Euros. Upon payment, ensure you receive and display the windscreen stickers confirming you have paid the toll. Failure to pay the road toll or to display the sticker may lead to a heavy fine. The cost for cars is three Euros for a one-week vignette, seven Euros for one month and 28 Euros for an annual permit, but prices may change. Costs are higher for freight vehicles and coaches for eight or more passengers. Tickets can be purchased at border points on entering the country or at post offices and at most petrol stations throughout Romania.
If driving, be alert for horse-drawn carts and livestock especially at night.
The police carry out frequent checks, and it is essential that you observe the speed limit, ensure that your vehicle is roadworthy and have with you all your car documents including evidence of insurance valid in Romania.
It is illegal to change money on the streets. Money should be changed in recognised exchange shops, banks and hotels.
Ask permission before photographing anything potentially sensitive (e.g. official buildings, police cars).
Contact your GP around eight weeks before your trip to check whether you need any vaccinations or other preventive measures. Country specific information and advice is published by the National Travel Health Network and Centre, and useful information about healthcare abroad, including a country-by-country guide, is available from NHS Choices.
If you are visiting Romania you should obtain a free European Health Insurance Card (EHIC) before leaving the UK. The EHIC is not a substitute for medical and travel insurance, but it entitles you to state provided medical treatment that may become necessary during your trip. Any treatment provided is on the same terms as Romanian nationals, so if a Romanian national is required to pay a fee towards their treatment, you would also have to pay the same fee. The EHIC will not cover medical repatriation, ongoing medical treatment or non-urgent treatment, so you should make sure you have adequate travel insurance and accessible funds to cover the cost of any medical treatment and repatriation. See our EHIC page and the NHS - About the EHIC page.
If you need emergency medical assistance during your trip, dial 112 and ask for an ambulance. If you are referred to a medical facility for treatment you should contact your insurance/medical assistance company immediately.
General - Money
Any person entering or leaving the EU will have to declare the cash that they are carrying if this amounts to 10,000 Euros or more; this includes cheques, travellers’ cheques, money orders, etc. This will not apply to anyone travelling via the EU to a non-EU country, as long as the original journey started outside of the EU, nor to those travelling within the EU.
Carry Euros in Romania. Dollars and Sterling are not always easy to exchange for the local currency especially outside of Bucharest. You may also have difficulties using travellers’ cheques and credit cards. Scottish and Northern Irish bank notes/coins may not be exchanged in banks and bureaux de changes.
The list may seem extensive, but it is always a good idea to have all your bases covered. Remember that this is a foreign country and your contries rules and laws no longer apply here. Common sense should prevail with you no matter where you travel to, always stay alert, keep a cool head and don't cause trouble. Above all, remember to enoy yourself! This is the trip of a lifetime!
