Driving in the UK and Scotland: licence rules, road rules and city zones

Driving in the UK is easier than many Thais expect, because the UK drives on the left, just like Thailand. Visitors with a full, valid foreign licence can drive for up to 12 months from entry. The adjustments are roundabouts, speeds in miles per hour, London charging zones and narrow roads in Scotland.

Which side does the UK drive on, and what changes?

England, Wales, Scotland and Northern Ireland all drive on the left, with the steering wheel on the right, as in Thailand. The differences are that speed limits and distances are in miles (mph), and at roundabouts you give way to traffic from the right and travel clockwise. Read the Department for Transport's Highway Code before you go.

Can you drive in the UK with a Thai licence?

Yes, within limits. The DVLA says visitors can drive vehicles covered by their foreign licence for up to 12 months from entering the UK, and nidirect gives the same guidance for Northern Ireland. Use the gov.uk checker for driving in Great Britain on a non-GB licence to confirm your own case.

Gov.uk does not state that visitors legally need an International Driving Permit (IDP), but car-hire companies may ask for one. Thai drivers can obtain an IDP from the Department of Land Transport (DLT), so ask your rental company before booking. See “What is an International Driving Permit, how do you get one, and can you actually drive abroad with it?”

What do you need to hire a car in the UK?

Before you drive away from the hire desk, photograph any scratches, confirm the car is right-hand drive with the gearbox you booked, and find the lights and wipers before joining a main road. City parking has its own rules: yellow lines usually mean restrictions at the times shown on nearby signs, so read the sign every time. In Wales, popular parking such as Pen y Pass in Eryri (Snowdonia) may need advance booking, so check Visit Wales before you go.

What should you know about driving in London: Congestion Charge and ULEZ?

Transport for London (TfL) runs the Congestion Charge in central London during set hours, and the Ultra Low Emission Zone (ULEZ) covers all London boroughs 24 hours a day except Christmas Day. Both apply to hire cars and foreign-registered vehicles. Check your vehicle and pay on the TfL website at the current rates.

For sightseeing inside central London, the Tube and buses are usually more convenient than a car, and hiring is more sensible when you plan to leave the capital.

Where are Scotland's Low Emission Zones?

Transport Scotland states that Low Emission Zones (LEZs) operate in Glasgow, Edinburgh, Aberdeen and Dundee, enforced by number-plate cameras. A vehicle that does not meet the standard can be penalised on entering, so check your hire car's registration on the official site before you plan a route.

How do you drive on single-track roads in the Highlands?

Single-track roads in the Highlands and islands are wide enough for one vehicle, with passing places at intervals. Pull into a passing place on your left, or stop opposite one on the right so the other driver can use it. Never park in a passing place, and let faster traffic behind you overtake when it is safe.

• Drive slowly and look well ahead for passing places before oncoming traffic arrives.
• Sheep, cattle and deer can appear on the road, so slow down and leave space.
• Refuel whenever you see a station, because petrol stations are far apart on islands such as Skye.
• In winter, days are short and it can be dark by mid-afternoon in Scotland, so plan to arrive before dark.

How should you use data and maps while driving, and where does signal drop?

Drivers need navigation, LEZ and ULEZ checks and online payment, so you want mobile data that works in the UK. EE, O2, Vodafone and Three cover cities well, but coverage has gaps in the Highlands, the islands and mountain areas. Download offline maps before you set off, and use a phone mount rather than holding the phone.
