Driving licences, eyesight and renewals
You need a valid licence that covers the category of vehicle you drive, and you must meet the relevant medical and eyesight standards. A standard Great Britain photocard normally needs renewing every 10 years; from age 70, driving entitlement is normally renewed every three years. Vocational licences, medical licences and Northern Ireland processes may differ.

Insurance, vehicle tax, MOT and roadworthiness
- Insurance: at least the legally required third-party cover when using a vehicle on a road or public place, subject to applicable exceptions.
- Vehicle tax: keep tax status correct; an off-road vehicle may need a SORN.
- MOT: most cars in Great Britain first need a test at three years old, then annually. In Northern Ireland, most cars first require testing at four years old, then annually. Vehicle-type exceptions apply.
- Roadworthiness: an MOT pass is not a promise your vehicle will remain safe. Check tyres, lights and other safety items regularly.
Driving without insurance and driving without a valid MOT are different offences with different consequences; do not assume both automatically result in identical penalties.

Speed limits: why the same road can have a different limit
For cars not towing, the national speed limit is generally 60 mph on a single carriageway and 70 mph on a dual carriageway or motorway. But posted limits, road conditions and vehicle categories can change what is permitted. Vehicles towing trailers, vans, buses and lorries can have lower limits.
In built-up areas, the usual default is 30 mph in England, Scotland and Northern Ireland, but 20 mph on many restricted roads in Wales. Local 20 mph or other signed limits can also apply elsewhere. A speed limit is a maximum, not a recommended driving speed.
Handheld phones, maps and music controls
It is normally illegal to hold and use a phone or other handheld interactive device while driving, including when stopped at lights or in a queue. This can include checking messages, choosing music or using maps.
There are limited exceptions, such as a genuine 999/112 emergency when stopping is unsafe or impractical, or certain contactless payments in a stationary vehicle. Hands-free systems are not a licence to drive while distracted. The normal fixed penalty for handheld use is £200 and six points, with more serious penalties possible in court.
Road signs, police stops and penalty points
Mandatory road signs and lawful directions from police officers must be obeyed. Police can require you to stop when safe, and may request your licence, insurance and MOT documents. If you cannot produce requested documents at the roadside, there are rules about providing them later.
Offences can lead to fines, endorsements, disqualification or other action depending on the circumstances. Different rules apply to newly qualified drivers and to some Northern Ireland endorsements.
What would you do?
Try these everyday situations. Open a card to reveal the answer — no trick questions, just useful road knowledge.
You're stationary at traffic lights. Can you pick up your phone to read a message?
No. The handheld-device ban normally still applies when stopped in traffic. Park safely before using the phone, unless a specific legal exception applies.
You're driving through a typical built-up road in Wales. Is 30 mph always the default?
No. Many restricted roads in Wales have a 20 mph default. Look for signs and obey the limit displayed at your location.
Your car passed its MOT last month. Are worn tyres now automatically legal?
No. A valid MOT does not remove the duty to keep the car roadworthy. Tyres must meet ongoing legal requirements for tread, condition and suitability.
You've just bought a car. Can you rely on the previous keeper's vehicle tax?
No. Vehicle tax does not transfer to a new keeper. Arrange tax before using the vehicle, unless a specific exemption applies, and ensure appropriate insurance is in place.
You drive a van or tow a trailer. Can you assume car national speed limits apply?
No. Limits depend on the vehicle and what it is towing, as well as the road and signs. Check your specific vehicle category before setting off.
Quick-reference guide: what changes across the UK?
Four nations share many road rules, but not every detail is identical.
England
The usual limit on restricted roads with street lighting is 30 mph unless signs show otherwise. Some local roads have signed 20 mph or other limits.
Scotland
The usual limit on restricted roads with street lighting is 30 mph unless signs show otherwise. Signed 20 mph and other local limits also apply.
Wales
20 mph is the default on most restricted roads with street lighting unless signs show another limit. Some roads have signed 30 mph or higher limits.
Northern Ireland
The usual limit on built-up roads with street lighting is 30 mph unless signs show otherwise. Signed 20 mph and other local limits also apply.
This is a practical overview, not a complete statement of law. Follow local signs and current official rules.
