Cyclists & Motorcyclists

Two of the road's smallest, most exposed users share your lane space every day. Learn the passing distance that keeps cyclists safe, why they sometimes ride centrally, and the habit that stops a motorcyclist disappearing at a junction.

A cyclist has no metal shell around them; a motorcyclist has a machine a fraction of a car's width. Both are common in hazard-perception clips because both can be genuinely hard to judge — how much room they need, why they position themselves the way they do, and how easily a motorbike hides in a gap your eyes have learned to skip over. This lesson covers all three.

💡
The big idea: Cyclists need real physical space and often position themselves centrally for their own visibility and safety, not to obstruct you; motorcyclists need a second, deliberate look at every junction because their narrow profile is genuinely easy to miss.
🎯 By the end, you'll be able to
  • State the minimum passing distance and speed guidance for overtaking a cyclist
  • Explain why a cyclist may ride in the centre of the lane or two abreast
  • Describe the 'Dutch reach' and why it prevents 'dooring' collisions
  • Explain why motorcyclists need a deliberate second look at junctions
📎 Helpful to know first

Cyclists need room, not just courtesy

A cyclist has nothing between them and the road but balance. A gust of wind, a pothole, or a car passing too closely can be enough to bring them down — and unlike a stationary hazard, they can't simply move out of your way at the last second without losing control. That's why the Highway Code sets an actual passing distance, not just a suggestion to "leave some room."

🔑 1.5 metres up to 30 mph — more above that
When overtaking a cyclist, leave at least 1.5 metres (about 5 feet) of space at speeds up to 30 mph, and give even more room the faster you're going. If there isn't enough space to do that safely — a narrow lane, oncoming traffic — wait behind the cyclist until there is, the same as you would for any overtake you can't complete safely.

Why a cyclist rides where they do

Cyclists are allowed to ride in the centre of the lane on quiet roads, in slow-moving traffic, and when approaching junctions — not to block you, but because it makes them clearly visible and prevents drivers from squeezing past in a gap that isn't actually wide enough. Two cyclists riding side by side ("two abreast") is also legal, particularly useful on quieter roads or when riding with children or less experienced riders, though a considerate cyclist will usually move to single file when it helps traffic pass on a narrower road.

✨ Central positioning is a safety choice, not an obstruction
A cyclist riding centrally near a junction is usually protecting themselves from a driver turning across their path or squeezing past just before the junction — one of the most common cyclist collision patterns. Treat it as a signal to hang back, not a reason to force a pass.

A grid of three UK cycling signs: a blue circular sign marking a segregated cycle track, a red-triangle warning that a cycle route crosses or joins the road ahead, and a red-ringed circle with a bicycle and a diagonal line meaning cycling is prohibited.

A blue circle gives an instruction (use this cycle track); the red triangle warns of a cycle route crossing ahead; the red-ringed circle prohibits cycling on that stretch of road or path.

The Dutch reach: checking before you open a door

A cyclist passing a line of parked cars can be struck by a door opened without warning — a collision known as "dooring." The Dutch reach is a simple habit that prevents it: use the hand furthest from the door to open it. Reaching across your body naturally turns your head and shoulders toward the door and the road behind you, so you check your mirror and blind spot for a passing cyclist before the door swings open, rather than after.

Motorcyclists: hard to see, easy to misjudge

A motorcycle presents a much narrower profile than a car, which causes two distinct problems at junctions. First, it can be hidden behind a windscreen pillar or another vehicle for the exact moment you glance that way. Second, because it's narrow and often approaches faster than expected, drivers can misjudge its distance and speed even when they do see it. The result is the classic "sorry, mate, I didn't see you" collision — pulling out of a side road or turning across a motorcyclist's path.

⚠️ Look twice — a deliberate second check, every time
Before pulling out of a junction or turning across oncoming traffic, make a second, deliberate look specifically for motorcyclists — they can be closer and faster than a first glance suggests, and a narrow profile is genuinely easy for your eyes to skip over the first time.

Check your understanding

1. What does this sign mean?
This blue circular sign is a mandatory instruction: cyclists must use the segregated cycle track rather than the main carriageway.
2. What is the minimum distance you should leave when overtaking a cyclist at speeds up to 30 mph?
Leave at least 1.5 metres when passing a cyclist at speeds up to 30 mph, and more room the faster you're travelling.
3. Why might a cyclist ride in the middle of the lane on a quiet road or near a junction?
Central positioning keeps a cyclist visible and stops drivers from overtaking through a gap that isn't actually safe — it's a protective choice, not an obstruction.
4. What is the 'Dutch reach' and what is it for?
Reaching across your body to open the door with your far hand naturally turns you to check your mirror and blind spot for an approaching cyclist before the door opens.
✅ Key takeaways
  • Leave at least 1.5 metres when overtaking a cyclist at speeds up to 30 mph — more the faster you're going — and wait if there isn't room.
  • Cyclists may legally ride centrally or two abreast; it's usually a visibility and safety choice, especially near junctions.
  • The Dutch reach — opening a car door with the far hand — turns your body so you check for a passing cyclist before the door opens.
  • A motorcycle's narrow profile makes it easy to miss or misjudge — take a deliberate second look before pulling out or turning across traffic.
➡️ Cyclists and motorcyclists share your speed of travel; next, two road users that move at a very different pace — horses and animals — and the extra room they need.

Frequently asked questions

How much room should I leave when overtaking a cyclist?
At least 1.5 metres (about 5 feet) at speeds up to 30 mph, and more the faster you're travelling. If you can't leave that much space safely, wait behind the cyclist until you can.
Is it legal for cyclists to ride two abreast?
Yes. Riding two abreast is legal and can be safer on quieter roads or when riding with children or less experienced cyclists, though a considerate cyclist will often move to single file to let traffic pass where the road narrows.
Why do drivers sometimes not see motorcyclists at junctions?
A motorcycle's narrow profile can be hidden behind a windscreen pillar or another vehicle for a moment, and its speed and distance can be misjudged even once seen — which is why a deliberate second look before pulling out matters.
