The Art of Using Car Mirrors
When you are learning to drive, one of the first habits you need to build is using your mirrors correctly. This is not just about passing your driving test — it’s one of the most important skills for becoming a safe, confident driver. Good mirror use helps you stay aware of what’s happening around your vehicle, anticipate hazards, and drive in a way that is considerate of others.
In this article, we’ll go over why mirrors matter, when to check them, how each one works, and some practical tips to help learner drivers build this essential habit.
Why Are Mirrors So Important?
Think of your car as being inside a moving “bubble.” To drive safely, you need to know what is happening all around that bubble — not just ahead. Your mirrors give you the information you need to:
- Anticipate hazards – spotting a motorbike weaving through traffic or a fast-approaching car.
- React in time – deciding whether it’s safe to slow down, overtake, or change lanes.
- Communicate effectively – understanding how your actions affect drivers, cyclists, and pedestrians around you.
Without regular mirror checks, you are effectively driving “half blind.”
The Three Key Times to Check Your Mirrors
The golden rule is simple: always check your mirrors before changing your car’s speed or position.
- Before signalling – you must know what’s behind you before telling others you intend to move.
- Before changing direction – whether you are turning, overtaking, moving lanes, or pulling over.
- Before changing speed – braking, accelerating, or even easing off the accelerator.
These three checks form the first step in the MSM routine (Mirror, Signal, Manoeuvre), a method every learner driver will practice until it becomes second nature.
Understanding Your Three Mirrors
Each of your mirrors gives you a different piece of the picture:
- Interior (centre) mirror – your main source of information. Shows what is directly behind and how close vehicles are. Is a car tailgating? Is a bike approaching fast?
- Right door mirror – covers the lane to your right. Vital when overtaking, changing lanes, or turning right.
- Left door mirror – covers the lane to your left. Essential for spotting cyclists before turning left or moving into a left-hand lane.
⚠️ Don’t forget the blind spot! No mirror covers everything. A quick glance over your shoulder is essential before moving off, overtaking, or changing lanes.
Interesting Fact: Mirror Laws Once Less Strict
Here’s a fascinating legal tidbit for your learners: in the UK, vehicles first registered before 1 June 1978 were allowed to have just one external mirror—typically the offside one. Nearside (passenger-side) mirrors weren’t made mandatory until after that date GOV.UKReddit. That means some classic cars legally ran without a mirror for decades!
Mirror Checks in Real Driving Situations
Here are some common driving situations and the correct mirror routine:
- Moving off from the roadside – Interior → Right Mirror → Right Blind Spot. Ensures it’s safe to rejoin traffic.
- Turning left at a junction – Interior → Left Mirror. Checks for cyclists or vehicles undertaking you.
- Turning right at a junction – Interior → Right Mirror. Confirms no one is overtaking.
- Changing lanes – Interior → Relevant Side Mirror → Blind Spot. Ensures the next lane is clear.
- Slowing down or stopping – Interior Mirror. Helps you judge if the vehicle behind can react safely.
- On a straight road – Check your interior mirror every 5–10 seconds. Maintains awareness of following traffic.
Building Good Habits as a Learner Driver
Using mirrors should become automatic, but that takes practice. Here are three simple tips to help you:
- Commentate while driving – say out loud, “Checking interior mirror, car behind at safe distance.” This reinforces the habit.
- Look before you brake – make it a rule: no brake pedal until you’ve checked your interior mirror.
- Scan, don’t stare – a mirror check is a quick glance, not a long look. Your main focus must remain on the road ahead.
❓ Frequently Asked Questions About Using Mirrors
1. When should learner drivers check their mirrors?
Learner drivers should check their mirrors before signalling, before changing direction, and before changing speed. Regular mirror checks (every 5–10 seconds on straight roads) help maintain awareness of what’s happening behind.
2. What is the MSM routine in driving?
MSM stands for Mirror, Signal, Manoeuvre. It’s the core routine learner drivers are taught. You check mirrors to see if it’s safe, signal your intentions, and then make the manoeuvre.
3. Which mirror should you check first?
Always check your interior mirror first, as it gives the most accurate picture of what is directly behind. Then check the relevant door mirror before making a move.
4. Why do I need to check my blind spot?
Your blind spot is the area your mirrors cannot cover. A quick glance over your shoulder ensures no cyclist, motorbike, or vehicle is hidden before you change lanes or move off.
5. Do examiners look for mirror checks in the driving test?
Yes. Examiners want to see regular and well-timed mirror checks, especially before signalling, braking, or changing lanes. Missing mirror checks can lead to minors — or even serious faults.
6. How can I build the habit of using mirrors?
Practice commentary driving by saying out loud when you check mirrors and what you see. This helps make mirror checks a natural, automatic habit over time.
Final Thoughts
For learner drivers, mastering mirror checks is one of the best investments you can make in your driving future. It’s a habit that not only improves your chances of passing the driving test but also makes you a safer and more confident driver for life.
Keep this guide handy, review it before each lesson, and remember: mirrors are not just for the examiner — they are for your safety and the safety of everyone around you.
