Understanding how to effectively use your mirrors and check blind spots is a fundamental skill for any moped rider. This lesson, part of Unit 6 on positioning and visibility, will ensure you know exactly when and how to perform crucial head checks to prevent accidents, especially when changing lanes or turning. Mastering these techniques is vital for both your theory exam and safe everyday riding.

Navigating the roads safely as a Category AM moped rider in Sweden demands constant vigilance and a highly effective visual strategy. One of the most critical aspects of this strategy involves the intelligent use of your mirrors combined with essential physical head turns, known as shoulder checks, to eliminate blind spots. This lesson, part of your Swedish Driving License Theory Course – Category AM (Moped), will provide you with the knowledge and techniques to develop a comprehensive visual scanning routine that can prevent collisions and ensure your safety, especially during dynamic maneuvers like lane changes, merging, and turning.
Effective visual scanning is not merely about looking ahead; it’s a dynamic, systematic process that encompasses your entire surroundings – front, sides, and rear. For moped riders, who are more vulnerable on the road, a disciplined approach to seeing and being seen is paramount. Mirrors offer crucial rearward and side views, but they are inherently limited. The areas they cannot reveal are known as blind spots, and these zones pose a significant risk if not actively checked. Developing a consistent scanning routine will significantly improve your hazard perception and reaction time.
As a moped driver, your field of vision is your primary defense against unexpected hazards. Other road users might not always see you, so it's your responsibility to see them. Mirrors allow you to monitor traffic approaching from behind and to the sides without constantly turning your body. However, vehicle geometry and the laws of physics mean that every vehicle has areas that its mirrors cannot capture. These "dead zones" are where other vehicles, cyclists, or pedestrians can hide, making a direct visual confirmation through a shoulder check absolutely essential before any lateral movement. Mastering this comprehensive approach is not just a best practice; it is a legal obligation in Swedish traffic law designed to standardize safety-critical habits.
Mirrors are fundamental tools that extend your field of vision, providing critical information about your immediate surroundings without requiring major head movements. Knowing the types of mirrors on your moped and how to properly adjust them is the first step towards effective visual scanning.
Most mopeds, like other motor vehicles, are equipped with at least two, often three, primary mirrors:
These mirrors are designed to give you quick, peripheral glances at your surroundings, allowing you to maintain your primary focus on the road ahead.
Mirrors come in different forms, and understanding their characteristics is crucial:
Never rely solely on a convex mirror for distance perception. Always supplement mirror checks with a physical shoulder check.
Correct mirror adjustment is a prerequisite for safe riding and must be done before you start your journey. Improperly adjusted mirrors create larger blind spots and reduce your overall awareness.
Sit in your normal riding position. Ensure you are seated as you would be while riding, including any passenger or cargo that might affect your moped's angle.
Adjust the interior rear-view mirror (if applicable). Position it so that you can see the lane directly behind your moped, with the horizon appearing slightly above the middle of the mirror's view. This provides maximum visibility of following traffic.
Adjust the left side-view mirror. Lean slightly to the left and adjust the mirror until you can just see a sliver of your moped's left side or bodywork. The primary focus should be on seeing the left rear lane and the adjacent lane clearly.
Adjust the right side-view mirror. Similarly, lean slightly to the right and adjust the mirror to show a sliver of your moped's right side, with the main view covering the right rear lane and adjacent lane.
Verify the settings with a quick shoulder check. After adjustment, perform a brief shoulder check to each side to ensure there are no major blind zones that you might have missed. Fine-tune as necessary.
Remember to re-adjust your mirrors anytime your riding position changes significantly, such as when you carry a passenger or a heavy load, as this can alter the moped's angle and affect your mirror's view.
Even with perfectly adjusted mirrors, there will always be areas around your moped that remain hidden. These critical zones are known as blind spots or dead zones. Understanding what they are and why they exist is fundamental to safe riding.
A blind spot (or dead zone) is a spatial area adjacent to and partially behind your moped that is not visible through any of your installed mirrors due to the vehicle’s own body structure and the limited angular field of the mirrors. Every moped, like all vehicles, has blind spots to its left and right sides.
These zones can typically extend 1 to 3 meters behind and to the side of your moped, varying slightly with vehicle design and mirror adjustment. Objects within these zones are completely invisible in your mirrors.
The primary danger of blind spots is obvious: another road user can be traveling in this unseen area, completely unbeknownst to you. If you initiate a lateral movement—such as changing lanes, merging into traffic, or even turning—without checking your blind spot, you risk colliding with that hidden vehicle, cyclist, or pedestrian. These side-impact collisions can be particularly severe for moped riders, often leading to serious injuries. Blind spots are a leading cause of accidents involving lane changes or turns, highlighting the absolute necessity of manually checking them.
Since mirrors cannot cover all areas, the shoulder check (also known as a head check) becomes an indispensable safety measure. It is the only way to get direct visual confirmation that your blind spots are clear.
A shoulder check is a brief, deliberate turn of your head and upper torso toward the side of your intended movement. It allows your eyes to directly scan the area that your mirrors cannot reach.
The shoulder check is not an optional extra; it is a mandatory part of safe riding and a legal requirement in Sweden. You must perform a shoulder check:
Skipping the shoulder check significantly elevates your risk of collision and can lead to legal penalties.
Effective visual awareness is a dynamic, sequential process. It combines mirror checks with the crucial shoulder check in a repeatable, systematic order. This sequence, often called the "Look-Signal-Look" routine, ensures no critical visual area is overlooked.
To guarantee a structured, repeatable visual sweep that reduces omission errors, always follow this order before any lateral movement:
Deviating from this sequence can create dangerous gaps in your awareness, especially in fast-moving traffic or complex situations.
Before you even begin your scanning sequence, you must communicate your intentions to other road users. This is where the Signal-Before-Scan Principle comes into play. Activate your turn signal before you start checking your mirrors and blind spots. In Sweden, the turn signal must be activated for a minimum of 3 seconds before the start of the maneuver. This alerts surrounding road users to your intentions, allowing them time to adjust their speed or position and creating a more predictable environment.
The correct order is: Signal → Mirrors (interior, left, right) → Shoulder Check → Execute Maneuver. Signaling after scanning increases surprise for other users and is illegal.
Mirror and blind spot checks are not a one-off event performed only before a maneuver. Continuous monitoring is a critical aspect of defensive riding. You should repeat mirror checks regularly, even when simply maintaining your lane.
Infrequent checks cause delayed reactions to overtaking or merging traffic, increasing your risk.
Swedish traffic regulations explicitly outline the obligations of drivers, including moped riders, regarding visual awareness. Adhering to these laws is essential not only for safety but also for legal compliance.
According to Trafikförordningen (Traffic Ordinance) 1998:112, § 3 9, before any lateral movement (such as a lane change, merging, overtaking, or turning into a side road), the driver must:
Trafikförordningen 1998:112, § 3 8 states that mirrors must be adjusted to provide the widest possible view of the rear and side traffic before the vehicle is started. This regulation also implicitly means re-adjusting mirrors after loading passengers or cargo, as changes in weight distribution can alter the vehicle's angle and thus the mirror's field of view.
Trafikförordningen 1998:112, § 4 2 mandates that turn signals must be activated at least 3 seconds before the start of any lateral maneuver and remain on until the maneuver is completed and the vehicle has stabilized in its new lane or position. This provides advance notice to surrounding traffic, allowing them sufficient time to react safely.
If your moped is equipped with convex side mirrors, you must be aware that they distort distance perception, making objects appear smaller and farther away. While providing a wider field of view, this distortion means that a shoulder check remains absolutely compulsory. Transportstyrelsen guidelines (e.g., Transportstyrelsen 2022/01 regarding mirror marking requirements) often include specific symbols (like "½") on convex mirrors to remind drivers of this effect.
The principles of mirror usage and blind spot checking remain constant, but their application needs to be adjusted based on prevailing conditions. Smart riders adapt their scanning frequency and technique to maintain optimal awareness.
Adverse weather and light conditions significantly impact visibility, making blind spots even more dangerous.
The context of the road also influences your scanning strategy.
Many collisions are a result of preventable errors in visual scanning. Being aware of these common mistakes can help you develop safer habits.
A disciplined and comprehensive visual scanning routine is the bedrock of safe and responsible riding. Its impact extends beyond simply avoiding fines; it directly influences your ability to prevent accidents and contributes to a safer road environment for everyone.
In Sweden, failing to adhere to the legal requirements for mirror and blind spot checks can lead to serious consequences:
By diligently following the principles outlined in this lesson, you not only comply with Swedish law but also significantly enhance your own safety and the safety of those around you.

Moped mirrors, like those on cars, have inherent limitations and cannot cover the entire area around the vehicle. A physical head check, or shoulder check, is essential to see what's in your blind spot – an area invisible in the mirrors. This is a critical safety step before any manoeuvre.
You must perform a head check before any manoeuvre that involves changing your lateral position or direction. This includes changing lanes, turning at intersections, merging into traffic, overtaking, or even pulling away from the side of the road.
A head check involves turning your head over your shoulder in the direction you intend to move or turn. It should be a quick but thorough scan to ensure no other road users, especially cyclists or other mopeds, are present in your blind spot.
Yes, questions regarding mirror usage, blind spots, and safe manoeuvring are common in the Swedish AM theory exam. Demonstrating understanding of these safety procedures is crucial for passing.
In adverse weather, visibility is often reduced, making blind spots even more critical. Ensure your mirrors are clean and adjusted, and always perform a thorough head check before any manoeuvre, as other road users may be harder to spot.
