The road is a shared space where thousands of strangers cooperate at speed without ever speaking. The rules of the road are simply the shared language that makes that possible — who goes first, where you sit, and how you tell others what you're about to do.
On UK roads you keep left, use lanes with discipline, and signal early and clearly so nobody has to guess. Overtaking is allowed when it's genuinely safe and legal — but there are many places you must never attempt it.
The single idea that ties it all together: priority is given, not taken. Having right of way is not the same as having a clear road. A safe driver holds their priority lightly and always leaves the other person a way out.

What you'll be able to do
- Understand who has priority at junctions — and why right of way is something you're given, never something you take.
- Understand which lane to pick on a roundabout, and a simple clock trick that takes the guesswork out of every exit.
- Understand when it's safe to change lane or overtake — and the one junction you must never block.
The facts that matter
- Keep to the left; use the right-hand lane only for overtaking or turning right
- Never overtake near a junction, bend, brow of a hill or pedestrian crossing
- At roundabouts, give way to traffic coming from your right
- In a one-way street you may pass on either side, whichever suits your exit
- Signal early and clearly — a signal is information, not a demand for priority
Make it stick
Memory anchors
Given, not taken
Right of way is a gift the other driver hands you. If they forget to hand it over, you don't grab it — you slow down. Priority you take is priority you crash on.
Left is home, right is a visit
Live in the left lane. Only visit the right to overtake or turn right, then come home. That keeps faster traffic flowing and stops you blocking the road.
The blind-spot bermuda triangle
Junctions, bends and hilltops all hide what's coming towards you. Overtaking there means gambling against a car you literally cannot see. Wait for the open, straight, clear stretch.
Stay sharp
The mistakes everyone makes
Treating right of way as a shield
"I had priority" is cold comfort at a collision. The other driver pulling out doesn't stop being a hazard just because you were in the right. The fix: read intentions, cover the brake, and be ready to give up a priority you're technically owed.
Living in the middle lane
On a dual carriageway or motorway, sitting in the middle lane when the left is clear is called lane hogging — it's an offence and it forces others to undertake. The fix: overtake, then move back left. Left is your default home.
Signalling too late — or into a gap
A signal flicked on as you're already turning tells other people nothing. Worse is signalling to force your way into traffic that hasn't offered space. The fix: indicate early so people can plan, but never assume the signal itself gives you the right to move.
Out on the road
What this looks like in real life
The tempting country overtake
You're behind a slow tractor on a rural road, itching to pass. Then you spot a field entrance ahead and a slight rise beyond it. That's a junction and a brow — two no-go zones stacked together. You hold back, and moments later a car crests the hill exactly where you'd have been.
The roundabout that flows
Approaching a busy roundabout, you glance right, see a steady stream, and ease off rather than nosing out. A gap appears, you go smoothly, and the whole thing feels calm. You gave way to the right, chose your lane early, and never once had to snatch a priority.

Quick answers
Frequently asked questions
What does 'priority is given, not taken' actually mean?
It means having right of way never guarantees a clear road. Even when the rules say you may go, another driver might not yield. A safe driver treats priority as something offered by others, staying ready to slow or stop rather than insisting on their turn.
Where am I not allowed to overtake?
Never overtake approaching a junction, on or near a bend, at the brow of a hill, at a pedestrian crossing, or where road signs or markings forbid it. In each case something you can't see may be coming towards you, so wait for a clear, straight stretch.
Which lane should I normally drive in?
Keep to the left. On multi-lane roads the left lane is your home; use lanes to the right only to overtake or to position for a right turn, then move back left once you've finished. Sitting needlessly in a right-hand or middle lane holds up traffic.
Who has priority at a roundabout?
Give way to traffic coming from your right, since it's already on the roundabout. Choose your lane before you arrive based on your exit, signal in good time, and only join when there's a safe gap — never force your way into the flow.
Can I overtake on the left in a one-way street?
Yes. In a one-way street all traffic moves the same direction, so you may pass on whichever side is clear and suits your intended exit. Signal your move, check your mirrors and blind spot, and position early for the lane you need.
