You signal, glance at your mirror, start drifting over, and then it hits you: you never looked over your shoulder. If that sounds familiar, you’re far from alone. Missed blind spot checks are one of the most common habits new drivers struggle with, especially in Ottawa traffic, where lanes merge quickly and cyclists, buses and trucks seem to appear from nowhere. The good news is that this is a habit problem, not a talent problem, and habits can be rebuilt. Here’s why it happens and how to fix it.
What Is a Blind Spot Check, and Why Does It Matter?
A blind spot is the area beside and slightly behind your vehicle that your mirrors can’t show. A blind spot check (or shoulder check) is a quick head turn in the direction you plan to move, to confirm nothing is hiding there. Examiners watch for it on lane changes, turns and curb pull-aways. Skipping shoulder checks is described as one of the most common reasons students fail the G2 road test, and a mirror check alone isn’t enough.
The law is more nuanced than most learners expect. According to The Globe and Mail, provincial laws don’t mention looking over your shoulder, but they do require you to make sure a lane change is safe, and driver manuals teach the shoulder check as the way to do that. If you skip it and a collision follows, the responsibility is yours.
7 Reasons You Keep Forgetting Your Blind Spot Check
1. Your brain is overloaded.
New drivers juggle speed, steering, signals, mirrors and traffic at once. The shoulder check is the first thing to drop when attention runs out.
2. Nerves take over.
An examiner in the passenger seat or heavy traffic can make you freeze up and fall back on the easiest check, the mirror.
3. You don’t trust your mirrors (or you rely on them too much).
Poorly adjusted mirrors create bigger blind spots, and some drivers lean on mirrors alone and never turn their head.
4. You have no fixed routine.
If your lane change order changes every time, steps get skipped. A routine makes the check automatic.
5. Looking away from the road feels risky.
Many learners avoid the head turn because they fear losing sight of the road ahead. A proper check takes about a second.
💡 Tip: Keep the head turn quick and controlled, then return your eyes to the road. Don’t stare at the blind spot.
6. You trust technology too much.
Blind spot monitoring helps, but it’s a backup, not a replacement for your eyes.
7. You only practise it on “big” moves.
Learners remember it on highways but forget it when pulling away from a curb or leaving a driveway.
Blind Spot Checks by the Numbers
| Finding | Why It Matters |
| Drivers who don’t look over the shoulder before changing lanes were about 3.85 times more likely to be involved in crashes in one lane-change study. | Skipping the check measurably raises crash risk. |
| In that same study, drivers glanced over the shoulder in only about 8% of right-to-left lane changes. | Most people under-use the habit. |
| Vehicles with blind spot monitoring had 14% fewer lane-change crashes, and 23% fewer injury crashes, than those without. | Technology helps, but it doesn’t replace a head check. |
| 18% of Ontario drivers in a DIG Insights study admitted making unsafe lane changes. | Unsafe lane changes are common on Ontario roads. |
| The average Ontario road test pass rate is 69%. | Roughly 3 in 10 test takers don’t pass, so small habits count. Factors affecting lane change crashes – ScienceDirect +4 |
What Real Drivers Are Saying
Community discussions show that drivers have different views on shoulder checks. In one Quora discussion, a driver argues that properly adjusted mirrors can provide a clear view during some lane changes. Other drivers in related discussions recommend looking over the shoulder to check areas that mirrors may not show.
These discussions highlight why blind-spot checks can be confusing for new drivers. For learners preparing for an Ontario road test, however, it’s important to follow the procedures taught by Ontario’s official driver-training guidance rather than relying on individual forum opinions.
A Simple Routine: Mirror, Signal, Shoulder, Go
Use the same four steps on every lane change:
- Mirror: check your rearview and side mirror for approaching traffic.
- Signal: show your intention early.
- Shoulder: turn your head over the shoulder on the side you’re moving to.
- Go: if it’s clear, steer smoothly across, then cancel your signal.
Do the shoulder check last, just before you move, so the information is fresh. If you check too early, traffic can change before you commit.
💡 Tip: Turn your head, not just your eyes. An eyes-only glance is easy to miss and impossible for an examiner to see.
⚠️ Warning: Don’t turn the steering wheel while looking over your shoulder. Keep your hands steady so the car doesn’t drift.
Practice Drills That Build the Habit
- Narrate out loud. Say “mirror, signal, shoulder, go” during every lane change until it’s automatic.
- Adjust your mirrors properly. Lean toward each side window and set the mirror so you just lose sight of your own car’s flank.
- Use a passenger as a spotter. Ask a licensed friend to tell you when you forget.
- Exaggerate for the test. Turn your head clearly enough that an examiner can see it.
- Check every move. Include curb pull-aways, driveways and parking lots, not just highways.
💡 Tip: Short, focused sessions of 10 to 15 minutes on quiet roads build the habit faster than one long, tiring drive.
Road Safety in Canada: The Numbers
Shoulder checks may feel like a small detail, but the national data shows why they matter. Canada recorded 1,964 road deaths in 2023, the highest total in a decade, and serious injuries reached a five-year high of 9,261. Ontario’s fatality rate remains the lowest in the country, which is a good reason to protect that record with careful habits.
Distraction was a factor in nearly 18% of fatal collisions that year, and a missed shoulder check is often a lapse in attention. These figures cover all collision types, not just lane changes, but they show how often crashes come down to attention and routine. A one-second head turn before every lane change is one of the easiest ways to stay on the right side of these numbers.

Final Thoughts
Missing your blind spot check doesn’t mean you’re a bad driver. It means the habit isn’t automatic yet. Set your mirrors correctly, follow one routine every time, and practise until your head turns without thinking. Do that, and you’ll be safer on Ottawa roads and far more confident on test day.
Frequently Asked Questions
1. Do you have to check your blind spot every time you change lanes?
Yes. Every lane change needs a blind spot check, even on a quiet road. Mirrors can’t cover the area beside and behind your car, and a vehicle, cyclist or motorcycle can sit there unseen. Turn your head just before you move, because a check done too early can be out of date by the time you commit.
2. How do you check your blind spot when changing lanes?
Follow Mirror, Signal, Shoulder, Go:
- Check your rearview and side mirrors.
- Signal early.
- Turn your head over the shoulder on the side you’re moving to, for about one second.
- If it’s clear, steer smoothly into the lane, then cancel your signal.
3. Can you fail your road test for not checking your blind spot?
Yes. Examiners watch for head movement on every lane change, turn and curb pull-away, and a mirror check alone isn’t enough. A single miss may not end your test, but repeated misses, or one that creates an unsafe situation, can mean a fail. Turn your head clearly so the examiner can see it.
4. What are two reasons you don’t notice a blind spot?
- Your mirrors aren’t set correctly. Poorly adjusted mirrors overlap too much with what you already see and leave a gap beside your car.
- Your attention is elsewhere. Distraction, nerves or a heavy workload mean you may glance at the space but not register a car in it.
Car pillars and headrests can also hide vehicles, which is why a head turn matters.
5. What is a blind spot check when driving?
A blind spot check (or shoulder check) is a quick head turn to look at the area your mirrors can’t show. Use it before changing lanes, merging, turning or pulling away from a curb.
6. Is a shoulder check mandatory in Ontario?
Ontario law doesn’t use the term “shoulder check,” but it does require you to make sure a lane change can be made safely first. Driver training and road tests treat the shoulder check as the way to do that, so make it a habit every time.
7. Do I still need to shoulder check if my car has blind spot monitoring?
Yes. In a U.S. study, vehicles with blind spot monitoring had 14% fewer lane-change crashes and 23% fewer injury crashes. That is a real benefit, but sensors can miss fast-approaching vehicles, and they don’t replace a head check on a road test.
8. How do I adjust my mirrors to reduce blind spots?
Lean your head toward the driver’s window and set the left mirror until you just see the side of your own car. Lean to the centre of the car and do the same on the right. With well-set mirrors, your blind spot shrinks and the shoulder check becomes a quick confirmation.
9. How do I remember to do a blind spot check every time?
Use the same routine on every lane change and say it out loud while practising. Apply it to every sideways move, including driveways, parking lots and curb pull-aways, not just highway lane changes. A passenger or an instructor can flag the checks you miss.
10. How can I practise blind spot checks before my G2 or G road test?
Practice on quiet streets, exaggerate your head, turn slightly so an examiner can see it, and ask a licensed friend to spot missed checks. For real-time correction, book G2 test preparation session.
