Understanding Blind Spots: Enhancing Driver Safety

What this actually means for you
Your hands and feet learn the car in a few weeks. Learning to read the road takes longer, and it starts with understanding what is on this page. Blind spots are the areas where the driver cannot see vehicles. The practical payoff is time: seeing things earlier means deciding earlier, and deciding earlier means nothing on the road ever has to be an emergency.
Blind Spots in Driving: Key Risks & Safety Tips
Blind spots are the areas where the driver cannot see vehicles. However, this can be solved by looking into the side mirrors. The driver must turn their head to check if a car is in one of those blind spots. Drivers must not linger in another driver's blind spot. If a driver is lingering, the driver must either drop back or pass the vehicle as soon as it is safe. However, another driver may not see their car and could change lanes and hit them.
Before changing lanes, look in the rearview mirror for nearby vehicles, motorcycles, and bicycles and perform an over-the-shoulder check to check the blind spot. Motorcycles and bicycles are small and may be hiding in a vehicle's blind spot.
Blind spots are regions around the vehicle where drivers may not see another car. This is because the mirrors do not cover that area, or the pillars are blocking the view.
Suppose there is another vehicle or road user in this region. In that case, the driver is unlikely to see them when they check their mirrors.
On the other hand, trucks have blind spots directly in front, to the left and right of their cabins and directly behind. Avoid being in this spot near a truck, as they will not be visible to the driver.
The driver should be aware of their vehicle's blind spots and check them before making any manoeuvres. They should also take measures to avoid being in another vehicle's blind spots.
Using this on Ontario roads — and on your road test
This is, quietly, the whole road test. Examiners spend the drive scoring how early you notice things: the pedestrian stepping off the curb on Lawrence Avenue, the brake lights three cars ahead on the DVP, the cyclist hidden by a parked SUV. GTA driving compresses all of it — merges on the 401, delivery vans double-parked on arterials, school zones at dismissal time. Practise narrating what you see when you drive with your instructor or supervisor: 'car pulling out, cyclist on the right, light about to change.' If you can say it early, you are already doing what this page teaches.
Questions drivers ask us
Can you explain blind spots in simple terms?
The driver must turn their head to check if a car is in one of those blind spots.
How do I actually get better at this?
Practise out loud. When you drive with your instructor or supervisor, say what you are seeing and what you plan to do about it: car waiting to pull out, watching it; light has been green a while, covering the brake. Commentary driving feels odd for one lesson, and then it sticks — it is how instructors build this skill.
How do examiners test this on a road test?
They watch your eyes and your timing: mirror and shoulder checks, how early you react to hazards, and whether your speed and following distance leave you room. You will not be asked theory questions — your driving is the answer.
