In the United Kingdom, cars drive on the left side of the road. Arriving by car from France, it's possible to take a ferry or cross on a shuttle car train running the Eurotunnel under the English Channel. The Channel Tunnel has provided a rail/road connection since 1994. Shuttle trains carry cars from Calais, France to Folkestone, the journey taking around 40 minutes. Fares start at £49 one way. The most basic motorway junction is a two-lane flyover with four slip-roads, where there are two on each side of the motorway, to exit or enter. In the country, the majority of motorways and dual carriageways allow a maximum speed limit of 70 mph (110 km/h) for cars.

As the United Kingdom is the place where the steam engine was invented, its railway network is the oldest in the world. More than 20 train operators service nearly 5,000 kilometres of electrified track, making it easy to get into and around the country. The famous Eurostar high-speed train service, running through the tunnel under the English Channel, allows you to reach London from Paris in 2.5 hours. For 4 to 15 days of unlimited travel on trains within the United Kingdom, it's recommended to invest in the BritRail Pass.

The United Kingdom boasts well over a hundred airports scattered around Great Britain, Northern Ireland and even the smaller off-shore islands. Virtually all of the airports serve international flights. London has a total of six airports: Heathrow, Stansted, Gatwick, Luton, Biggin Hill and London City. Heathrow Airport is considered Europe's busiest. It handles more than 60,000,000 international passengers per year, more than any other airport in the world. The major airports in Scotland are Edinburgh and Glasgow, Cardiff in Wales, and Belfast in Northern Ireland. The national carrier, British Airways, as well as a number of other airlines and low-cost carriers provide scheduled domestic and international connections.

There are regular ferry services that connect the British and Northern Irish passenger ports with harbours in Belgium, France, Denmark, Germany, Spain, Ireland, Norway and Sweden. Major ferry operators include P&O European Ferries, Stena Line, Sea France and many others. The most important ferry terminals are located in Plymouth, Poole, Dover and Portsmouth.

Major cities in the United Kingdom boast the world's oldest public transportation systems. The London metro, commonly known as the Tube, is the oldest underground system, in operation since 1863. The metro in Glasgow was opened in 1896, and is the third-oldest in the world. Apart from the underground, the major cities rely upon conveniently planned bus networks, with the famous red double-deckers servicing London. In recent years, tram service has seen a revival all around the country, with many cities restoring their previously neglected tram networks.
