You know where you want to go, but everything seems to happen at once. The indicator goes on, your speed changes and you are already steering before you have properly checked the space beside you. You may know the individual checks; the difficulty is giving yourself time to use them.
At Licence Link, MILO means Mirror, Indicate, Look Over, while MIB means Mirror, Indicate, Brake. MILO helps you prepare for a sideways move; MIB helps you prepare for a planned manoeuvre that needs signalling and a reduction in speed. Neither is permission to move, and neither should delay an urgent safety response.
In both cues, “Mirror” means the interior rear-view mirror, not a side mirror. The cues organise these particular actions; they are not a complete description of every observation a manoeuvre may require.
These cues are not just for someone trying to pass a driving test. Whether you are on P plates or have held a licence for years, they can help you organise the observations and decisions behind an everyday manoeuvre.
Start with the decision, not just the letters
A mirror check is only useful if you take in and understand what it shows. A quick glance followed by moving anyway does not become a sound decision because you remembered the acronym.
Ask yourself what you need to know: is there someone beside you, is a vehicle approaching from behind, and is the gap you noticed still suitable? Then use that information. Sometimes the correct outcome of a check is to wait.
The same applies to your indicator. It tells people what you intend to do; it does not tell them that you have already decided to move regardless of what they are doing.
MILO: Mirror, Indicate, Look Over
Think of MILO when you are preparing to change your position sideways, such as changing lanes or moving out from the kerb. The aim is to build a useful picture of the space you want to enter, communicate and check again before committing.
- Mirror: Check the interior rear-view mirror and understand what it shows about traffic behind you. Is a vehicle approaching the space you want, rather than simply sitting in it at the moment you look?
- Indicate: Give useful warning of the intended move. Keep your position while you assess the situation; switching on the indicator does not create a gap or give you priority.
- Look Over: Make a brief check of the relevant blind spot just before moving sideways. Return your attention ahead and move only when it is safe, continuing to monitor the situation in front of and behind the vehicle.
Looking over does not mean holding your gaze behind you while the car continues towards changing traffic. Keep the check brief and purposeful, and maintain your lane position while you do it.
If you signal but then have to wait, the first observation is not a permanent clearance. Traffic may have changed, so reassess before moving. If you abandon or finish the manoeuvre, make sure the indicator is no longer sending the wrong message.
A lane change that does not need to be rushed
Imagine you need the next lane for an upcoming turn. You check the rear-view mirror and notice a car closing from behind in that lane. That observation gives you a reason to plan, not a reason to hurry across before it arrives.
Communicate your intention, keep your lane and let the situation develop. When a suitable gap is available, check that it is still clear, including the relevant blind spot, before moving gradually. If the turn becomes unreachable without a rushed move, continue and find a suitable alternative route.
The freeway version involves the same need for useful observations, but also has specific merging and lane-discipline considerations. Our Freeway Driving guide explains those situations without treating every entry ramp as the same layout.

Moving off from the kerb
Our established cue is “Set to move. M.I.L.O. Then go.” Get the vehicle ready before the final observations, rather than checking the traffic and then spending time sorting out the controls while that picture changes around you.
Allow the required signalling time and check the space you will enter before moving out. “Then go” still means only when safe and after giving way as required, not automatically as soon as you have looked.
MIB: Mirror, Indicate, Brake
MIB is useful when you can see a planned manoeuvre coming, such as turning into a side road or slowing to pull in and park. It helps you prepare before everything becomes a last-second action.
- Mirror: Before a planned reduction in speed, check the rear-view mirror for what is happening behind you when it is safe to do so. Notice whether someone is close and give yourself room to slow progressively, rather than arriving at the turn and suddenly braking.
- Indicate: Signal the intended turn or movement early enough to give useful warning. Make the signal clear for the manoeuvre you actually intend, rather than leaving others to guess why you are slowing.
- Brake: Reduce speed to suit the manoeuvre, visibility and conditions. Use controlled braking as the situation allows, keeping your attention on the road and other road users.
The point is not to rush through three actions and call the preparation finished. Looking earlier gives you more opportunity to communicate and adjust progressively.
A planned turn into a side road
You know the left turn is coming up. Instead of reaching the corner and then trying to signal, brake and work out who is around you, start preparing while you still have time.
Check behind, signal the turn and reduce speed appropriately. Continue looking for people and vehicles around the turn, and make any additional observations needed before changing position. MIB does not replace giving way or checking the area your vehicle will enter.
If another driver is close behind, that is information to use in your planning, not a reason to take the corner too fast. Prepare earlier where possible, but respond to the situation in front of you when braking is needed.
When you need both cues
Some manoeuvres involve both slowing down and moving sideways. Entering a turning lane is an everyday example: you need to prepare your speed and also check that the lane you want to enter is available.
MIB does not remove the need for a blind-spot check, and MILO does not remove the need to choose an appropriate speed. Use the cues for the decisions in front of you, with a fresh check of the relevant blind spot just before the sideways movement.
Do not try to force every situation into one long memorised sequence. The road layout, traffic and required give-way decisions still govern what you can do and when.
Roundabouts add their own questions about lane selection, entry gaps and exits. Our roundabout guide covers those decisions; the observation cues here are preparation, not a complete set of roundabout instructions.

What the cues do not mean
The letters are a reminder, not a rule that overrides what is happening around the car. These distinctions matter just as much as remembering what each letter stands for.
- Not an indicator before every brake application: If you are slowing for a queue while continuing straight ahead, you are not signalling a turn. In a car with working brake lights, those lights communicate braking; do not add a misleading left or right indicator just to complete MIB.
- Not a delay before emergency braking: If an immediate hazard requires you to brake, respond. Do not wait to complete a mirror-and-indicator routine first.
- Not permission to take a gap: An indicator, mirror check and shoulder check do not give you priority over a vehicle in the lane you want to enter.
- Not a reason to stare behind: A useful blind-spot check is brief and relevant. You still need to monitor your path and what is happening ahead.
You also need to be able to make these observations without unintentionally steering out of position. If the shoulder check and steering are getting tangled together, that is a practical skill to work on with support, not something to rush through in busier traffic.
Common questions about MILO and MIB
Are MILO and MIB official WA road rules?
No. They are the coaching cues we use to help organise observations, communication and preparation. WA road rules determine matters such as signalling, giving way and when a lane change can be made safely; remembering a cue does not replace those obligations.
How long should I indicate?
Give enough warning for other drivers and pedestrians to understand your intention. Do not treat a fixed number of flashes as the complete answer for every situation.
There is a specific WA requirement when joining a line of traffic from a stationary position at the side of the carriageway or from a centre-of-the-road parking area: signal continuously for five seconds before pulling out. That does not turn every lane change into a universal five-second formula, or remove the need to check and give way.
Do I need to look over if I have already checked the rear-view mirror?
For a sideways move, the rear-view-mirror check and relevant blind-spot check do different jobs. Do not assume that the space beside you is clear just because you did not see a vehicle in the rear-view mirror.
Make the blind-spot check close to the movement, not well before it and then rely on an old picture. If you have had to wait, reassess.
What if I remember the letters but still feel rushed?
Look at when you start preparing. If you only begin checking when you reach the turn or need to leave your lane immediately, you have given yourself very little room to make a decision.
Choose one thing to work on, such as noticing the turn earlier or keeping your steering steady during a brief shoulder check. Practical coaching can help identify which part needs attention rather than assuming the answer is simply to drive more.
Make the next drive useful
Choose a familiar route and suitable conditions, and pick one observation habit to focus on. Do not add unnecessary lane changes or difficult manoeuvres just to practise an acronym.
Afterwards, once safely parked, ask what the check actually helped you notice. “I saw the car approaching in the next lane and waited” is more useful than “I did a head check.” You are looking for an observation that informed a decision.
Build a clearer approach to everyday driving
You do not have to wait until you feel completely confident before asking for support. A useful starting point is knowing which part of your driving feels rushed or unclear and working on the observation, timing and decisions behind it.
The Licence Link Defensive Driving Course is a three-hour, face-to-face course for $297, with automatic and manual options. It is for licensed drivers, from red and green P-platers through to full licence holders who want to improve their skills or confidence.
The session includes briefing, practical coaching and debriefing, with priorities shaped around the areas you want to improve and the driving observed during the session. Freeway merging, lane changes and multi-lane planning are possible focus areas, or maybe parking is still something you avoid doing.
Drivers from across the Perth metropolitan area are welcome. Participants travel to our Bull Creek meeting point, south of the river. Bull Creek is where we meet, as it provides close access to all driving environments including the City, freeways right through to heavy industrial areas.
Your included resources are a personal digital feedback form and relevant digital cheat sheets. No subscription is needed. The aim is to leave with clearer priorities for your driving, not a guarantee that one session will remove every difficult moment.
Explore the Defensive Driving Course if you want practical help making your everyday driving decisions feel less rushed.
