Anyone who goes karting regularly will probably recognize it immediately: on many tracks, you drive to the right, so clockwise. It feels so natural that you hardly stop to think about it. Yet, that driving direction is rarely chosen by chance. Behind the scenes, multiple practical, technical, and even human considerations play a role — from the geometry of the human body to the complexity of track maintenance.
Is driving clockwise really the standard?
Many kart circuits do indeed opt for a clockwise layout. This means that you have a relatively large number of right-hand turns and that the flow of the track is tailored to this. It is not a hard and fast rule — there are plenty of tracks that run counter-clockwise or alternate — but clockwise layouts occur remarkably often, especially at indoor and recreational circuits.
Interestingly enough, this pattern applies more broadly than just karting. On motorcycle and car circuits, you also regularly see a clockwise direction of travel. Oval circuits, which are particularly popular in North America, on the other hand, run counter-clockwise by default. This has to do with banking angles (the tilt of the track) and the historical development of American motorsport, where the steering wheel is typically mounted on the right or in the center. In that case, racing is done clockwise.
The human factor: anatomy and the brain
One of the most fascinating — and least known — explanations for driving direction choices lies in our biology. Research shows that most people have a preference for a particular turning direction, and that this has to do with the asymmetrical functioning of the brain.
According to scientific research into directions of movement, the tendency to turn is likely caused by an asymmetrical development of both hemispheres. Dopamine concentrations in the left and right hemispheres are not equal, and people tend to turn in the direction of the hemisphere with the lowest dopamine concentration.
In running and skating, this effect is well documented. As early as the nineteenth century—a Dutch sports magazine from that period describes it explicitly—leftward (counter-clockwise) was considered the "preferable" skating direction: the right leg, which is the strongest for most people, can then be optimally utilized for the push-off. The 1908 Olympic Games codified this principle by stipulating that athletics would always be skated counter-clockwise.
In karting, this works differently because the power comes from the engine rather than the legs. Nevertheless, body asymmetry still plays a subtle role: when karting clockwise, your body is consistently pushed to the left in corners, which is a relatively familiar load for most right-handed drivers. Consequently, the sense of control—and thus the confidence among recreational drivers—is slightly greater.
Safety and clarity
One of the most direct reasons for a fixed direction of travel is simply safety and clarity. Kart tracks attract many beginners and casual drivers. For this group, it helps if everything is as predictable as possible. A fixed direction of travel prevents confusion and makes it easier for track staff to assess situations and react quickly.
In countries where traffic drives on the right — such as the Netherlands — driving clockwise also offers a practical advantage for visibility: the driver sits on the left, giving them a clear view of the center of the turn when turning right. We are familiar with this principle from parking garages as well, where driving counter-clockwise is often recommended because the driver has a better view of approaching traffic and available spaces from their seating position.
When a circuit is driven in the reverse direction, run-off zones, guardrails, and sightlines change dramatically. As is also evident in Formula 1 when circuits are theoretically reversed: corners that normally have safe run-off zones can, in the reverse direction, suddenly border directly on walls or grandstands without any margin. On kart circuits, which are already naturally compact, this argument carries significant weight.
The design of the track
The available space largely determines the layout of a circuit. Especially for indoor tracks, a designer has to puzzle over pillars, walls, and limited square footage. In such a process, a "logical" direction of travel often emerges: a direction in which the turns connect well, the flow is correct, and the speed differences between sections are manageable.
In many cases, it simply works out better when you drive the circuit clockwise. That is not a law of nature, but rather a consequence of how the space is utilized — and of the fact that track designers have traditionally worked with clockwise as a starting point, just as architects of parking garages take counter-clockwise as the standard.
Furthermore, a well-designed circuit has a balance between right- and left-hand corners that are pleasant to drive. With a fully asymmetrical layout—where almost all corners are in one direction—it is especially important that the steepest corners are positioned correctly in the design. This influences the flow, the maximum speeds, and the excitement on the circuit as a whole.
Technique: what the direction of travel does to a kart
A kart is a unique vehicle. Unlike a car, a kart does not have a differential on the rear axle: both rear wheels are attached to the same rigid axle. This means that when taking a corner, the outer wheel travels a greater distance than the inner wheel. To compensate for this, the steering system of a kart is designed so that the inner rear wheel lifts and the outer wheel lowers when turning, causing the inner rear wheel to briefly leave the ground and allowing the kart to turn smoothly.
In principle, this mechanism works the same way when driving left or right, but it does make the chassis setup direction-sensitive. This is because a kart is not built completely symmetrically: the engine is usually located on one side, the driver sits asymmetrically, and various parts are not perfectly mirrored. As a result, the g-forces generated in left turns are naturally slightly different from those in right turns.
On circuits with a highly asymmetrical layout — many more right-hand than left-hand turns, or vice versa — this is noticeable in the setup. A kart optimally set up for a clockwise circuit ideally has a slightly different weight distribution than a kart for a counter-clockwise circuit. For rental tracks, this is a practical argument for sticking to one fixed direction of travel: the karts can then be adjusted so that they behave predictably and stably for every driver.
Wear and maintenance
Driving direction also has a direct influence on material aging. If you always drive in the same direction, tires, brakes, and the road surface itself wear in a predictable, consistent manner. For rental tracks, this is a significant logistical advantage: maintenance intervals are easier to plan, parts behave consistently, and replacement patterns are predictable.
This effect is clearly visible among motorcyclists on circuits: on a left-hand circuit like the Sachsenring — with only three right-hand corners and the rest left-hand — the right side of the tires wears down significantly faster than the left side. The same logic applies to karts. By always driving in one direction, the outer tire towards the dominant corners always wears down the fastest. For a rental track that wants to switch driving directions, this means the wear distribution changes — which can have advantages in itself, but also requires extra attention to planning.
The road surface itself is also affected by the direction of travel. The rubber granules left behind by tires on the asphalt — the so-called "marbles" — build up along the racing line of the dominant direction. This provides grip, but makes a change more complicated: after all, the new racing line lies elsewhere, and the circuit does not yet have a rubber layer in that direction.
Physical strain on the rider
While karting, you have to cope with significant lateral forces. On a right-hand circuit, your body is pushed to the left in every corner — your ribs, neck, and shoulders continuously absorb those forces. After a few sessions, you notice that one side is under more strain than the other.
For recreational drivers, this is hardly a problem. However, for serious kart racers, the one-sided load is a recognized point of concern. Professional drivers perform targeted physical training to strengthen the neck and core muscles on both sides. On circuits that alternate driving directions, drivers can better distribute their load and train more symmetrically.
This is also a reason why training circuits and competition-oriented tracks switch direction more often: it makes drivers more versatile and physically better balanced.
Why some jobs *do* change
Not all kart circuits stick to a single direction. On outdoor tracks and circuits that are also used for serious training and competition, you see deliberate variation more often. The reasons are manifold:
Challenge and variety. When you drive a circuit in reverse, you won't recognize it anymore. Familiar braking points, turn-in moments, and racing lines must be relearned. This increases the technical challenge and keeps the driving engaging, even for experienced kart drivers.
Symmetrical development. For riders who want to improve, it is valuable to ride corners in both directions. Just like a tennis player who trains both their forehand and backhand, a racer benefits from experience with both left and right turns.
Fairer wear. By alternating, you distribute wear across both sides of the tires and the track. This can extend the lifespan of materials, although it also requires more attention to planning.
The downside is that switching places higher demands on the infrastructure: run-off zones, guardrails, and directional signs must function in both directions. Not every circuit is built for this.
The broader context: direction of travel in motorsport
Karting does not stand alone. In the broader motorsport world, racing disciplines are often the result of historical, geographical, and technical choices made decades ago.
Formula 1 circuits almost all run in a fixed, specially designed direction. Driving an F1 track in reverse is theoretically interesting, but in practice it encounters major safety problems: run-off zones calculated for the normal direction of travel are positioned in the wrong place when reversed. Walls that are normally far away sometimes lie directly in the collision line after a braking zone on a reversed circuit.
Oval circuits in North America run counter-clockwise by default, with steeply banked corners and walls instead of run-off zones. This is so deeply ingrained in the tradition and design of these tracks that switching is technically impossible.
In the karting world, there is slightly more freedom — circuits are more compact and speeds are lower — but the same fundamental considerations apply here as well.
More than a random choice
The fact that many kart tracks have clockwise driving is no coincidence, nor is it arbitrary. It is the combined result of practical choices regarding safety, track design, equipment maintenance, technical tuning, and ease of use — supplemented by subtle influences from human anatomy and habit.
At the same time, it is not an immutable law. Circuits that deliberately vary driving direction offer drivers an extra challenge and ensure more balanced development — but pay a price for this in complexity and infrastructure.
The next time you go karting, it is worth paying attention. Not just to the direction, but also to how the corners flow into one another, where you are stressed the most, and how the track utilizes the space. Chances are you will notice that there is more to it than meets the eye.
