The real danger of the blind spot is that it creates a false sense of security. You may think the road is clear because your mirrors show nothing but another road user could still be right next to you.

‍

This is one of the most common causes of:

‍

• Lane-change accidents
• Collisions with cyclists or motorcyclists
• Near-misses in busy traffic

‍

That’s why awareness and proper checking are absolutely critical.

The short answer is: no.

‍

No matter how well you adjust your mirrors, there will always be areas around your vehicle that remain invisible. Mirrors help reduce blind spots, but they can never remove them completely.

‍

That’s why one rule is absolutely crucial:

‍
Always check over your shoulder before changing lanes or turning.

‍

This quick glance, often called a shoulder check, is the only reliable way to make sure there isn’t a cyclist, scooter, or car right next to or slightly behind you.

Knowing when to check your blind spot is just as important as knowing how. You should always do a shoulder check in situations like:

‍

• Changing lanes
• Merging into traffic
• Turning at intersections
• Overtaking another vehicle
• Leaving a parking spot

‍

In short: any time you move sideways or change direction, check your blind spot.

Imagine two zones next to your vehicle:

‍

• Part 1: Visible in your side mirror
• Part 2: Not visible in your mirrors

‍

The blind spot is Part 2.

‍

This is the area where another road user, like a cyclist or motorcyclist, can be completely invisible to you. The only way to check this area is by physically turning your head and looking over your shoulder.

‍

Blind spots don’t just apply to cars. In fact, larger vehicles like lorries and buses have much bigger and more dangerous blind spots.

‍

Why Are Their Blind Spots Bigger?

‍

• They are longer and taller
• The driver sits higher up
• They have limited direct visibility

‍

Even though these vehicles often have extra mirrors, they still cannot show everything around the vehicle.

If you’re driving near a lorry or bus, keep these safety tips in mind:

‍

• Keep your distance
• Make sure you are visible in the driver’s mirrors
• Avoid driving directly next to them
• Never stop right in front of or beside a large vehicle

‍

If you can’t see the driver in their mirror, chances are—they can’t see you either.

Buses have multiple blind spots, and they can vary slightly depending on the vehicle. Generally, the key blind spot areas are:

‍

• Next to the bus (side blind spot)
• Directly behind the bus

‍

Even though some areas may be visible through mirrors, large sections around the bus remain hidden from the driver.

‍

The important takeaway: A bus has several blind spots, not just one.

The blind spot is one of the most important safety concepts in driving. You cannot eliminate it, but you can manage it.

‍

Mirrors are helpful, but they are not enough on their own to guarantee safety. A shoulder check is essential to fully observe your surroundings and eliminate what your mirrors cannot show. In addition, extra caution is needed when driving near large vehicles, as their blind spots are significantly bigger and more dangerous.

‍

By understanding and respecting blind spots, you significantly reduce the risk of accidents and become a safer, more confident driver.
