Winter tires & snow chains

No legal requirement for winter tires or chains anywhere in the UK, even in Scotland's more mountainous areas — carry them at your own discretion if traveling in winter through remote or high-altitude routes.

Tolls

System
Mixed tolls

Most UK roads have no toll, but a handful of specific crossings and roads charge a fee (e.g. the Dartford Crossing near London, the M6 Toll near Birmingham); pay online or at the crossing. London and a few other cities also charge separate congestion/low-emission zone fees for entering, which function like a toll but aren't a road-use charge.

More things to know before you drive

Seatbelts
Mandatory front and rear for all occupants.
Mobile phone use
Hands-free only; holding or otherwise using a phone while driving (including at a red light) is prohibited, with a fixed penalty and licence points.
Child seats
Children must generally use an appropriate child car seat until they are 135 cm tall or turn 12, whichever comes first; a seatbelt is sufficient after that.
Headlights
Not generally mandatory in daylight; dipped headlights are required from dusk to dawn and in poor daytime visibility.
Low-emission & restricted zones
London has a Congestion Charge zone and an Ultra Low Emission Zone (ULEZ) covering nearly the whole city; several other UK cities (e.g. Birmingham, Bristol, Bath) run their own Clean Air Zones — non-compliant vehicles pay a daily charge, checked by camera.
Right of way & roundabouts
There is no general "priority to the right" rule — give way according to posted signs and road markings. Roundabouts (very common in the UK) go clockwise; give way to traffic already on the roundabout, approaching from your right.
Parking
Yellow lines along the road indicate parking restrictions (double yellow generally means no parking at any time, single yellow means restricted at certain times); paid bays are common in towns via meter or app.
Speed cameras
Fixed and mobile cameras are widespread, including average-speed camera stretches on motorways and major roads.

Good to know

Drives on the left, unlike every other country currently listed here — if you're used to right-hand traffic, take extra care at junctions and roundabouts. Speed limits are posted in mph, not km/h (the km/h figures above are the metric equivalent for comparison): 30 mph in towns, 60 mph on single-carriageway roads, 70 mph on motorways/dual carriageways. Scotland has a stricter drink-drive limit (0.5‰) than England, Wales, and Northern Ireland (0.8‰, shown above). The emergency number 999 is standard; 112 also works and reaches the same services.
