How much space to give cyclists when overtaking, and what the Highway Code says

Drawing of a bicycle on the tarmac

Oxford is one of the best known cycling cities in the UK, so passing cyclists safely is something you will practise on almost every lesson. Getting it wrong is one of the easiest ways to put someone at risk, and it can also cost you your driving test. Here is what the Highway Code actually says, and how to apply it on Oxford's roads.

What the Highway Code Actually Says

Rule 163 of the Highway Code says you should leave at least 1.5 metres when overtaking cyclists at speeds of up to 30mph, and give them more space when overtaking at higher speeds.

🚲

Cyclists

Leave at least 1.5 metres at speeds of up to 30mph, and give them more space at higher speeds.

🐎

Horse riders and horse drawn vehicles

Pass at speeds under 10mph and allow at least 2 metres of space.

🚶

Pedestrians walking in the road

For example where there is no pavement. Allow at least 2 metres and keep to a low speed.

Guidance, but still enforced

These are "should" rules in the Highway Code rather than specific offences. However, passing too close can still lead to a prosecution for careless or dangerous driving, and police forces use close pass operations to spot and educate drivers.

Why Cyclists Need That Space

The Highway Code was updated on Saturday 29 January 2022 with several changes that affect how drivers and cyclists share the road.

  • ASudden movementsCyclists may need to move out suddenly to avoid potholes, drain covers or car doors opening.
  • BWind from passing carsWind from a passing car can push a cyclist off line, especially at higher speeds.
  • CTime to reactMore space gives both you and the cyclist time to react if something unexpected happens.

Other Highway Code rules about cyclists

  • Hierarchy of road users: those who can cause the greatest harm have the greatest responsibility to reduce the danger they pose to others.
  • Centre of the lane: cyclists may ride in the centre of their lane on quiet roads, in slower traffic and at junctions or narrowings. This is not bad cycling, and you should not try to squeeze past.
  • Two abreast: cyclists may ride two abreast, and should move into single file when it is safe to let you overtake.
  • Turning at junctions: do not cut across cyclists going ahead. Give way to them as you would to a motor vehicle.
  • Opening doors: use the hand furthest from the door, which makes you turn and look behind for cyclists.

Passing Cyclists Around Oxford

In Oxford you will meet cyclists on almost every road. These are some of the most common situations on lessons.

🚗Busy roads with parked cars on one side, where there is often not enough room to leave 1.5 metres, so waiting behind is the right choice
🚲Cycle lanes that end suddenly, where cyclists need to rejoin the main traffic
🔄Roundabouts, where cyclists may stay in the left lane even when they are going right round
⚠Narrow roads with traffic islands or pinch points, where you should not overtake a cyclist just before the narrowing
How close passes affect your driving test

Examiners watch closely how you deal with cyclists. Passing too close, cutting in after overtaking, or turning across a cyclist's path can all be marked as faults, and a serious fault if it causes the cyclist to change speed or direction. Equally, hanging back when there is clearly enough room can be marked as a lack of progress. Patience is the key skill: in slower city traffic, waiting a few seconds behind a cyclist rarely costs you any real time.

Passing Cyclists, Step by Step

1

Look well ahead

Spot cyclists early so you can plan your pass.

2

Check the road

Check for oncoming traffic, junctions, traffic islands and parked cars before moving out.

3

Wait if you must

If you cannot give at least 1.5 metres, slow down and wait behind at a safe distance.

4

Move out in good time

Do not cut back in until you are well past.

5

Avoid the horn

Using the horn can startle a cyclist.

6

Check before turning left

Check your left mirror and blind spot before turning left, especially near cycle lanes.

Overtaking Cyclists: Your Questions Answered

How much space should I give a cyclist when overtaking?
At least 1.5 metres at speeds of up to 30mph, and more space at higher speeds. If there is not enough room to do this safely, wait behind the cyclist until there is.
Is it 2 metres at speeds over 30mph?
The Highway Code does not give a specific figure for cyclists above 30mph. It says to give them more space. The 2 metre figure applies to horse riders, horse drawn vehicles and pedestrians walking in the road.
Can I cross a solid white line to overtake a cyclist?
Yes, if it is safe. The Highway Code allows you to cross a solid white line to pass a cyclist, horse rider or road maintenance vehicle travelling at 10mph or less.
Why do cyclists ride in the middle of the lane?
The Highway Code advises cyclists to ride in the centre of their lane in certain situations, such as on quiet roads, in slower traffic and at junctions, so drivers can see them clearly and do not try to overtake where it is unsafe.
