Swiss Category A Theory common mistakes

Swiss Category A Theory · Understand the traps and how to avoid them.

Mistake 1

Treating the right-hand priority rule as absolute and failing to apply the exceptions: not yielding when emerging from a priority road, from a dirt track or field path, when a tram is present, or in the specific cases where priority is reversed.

Candidates memorise "rechts vor links" (right before left) as a slogan and then apply it mechanically, without anchoring the exceptions to the sign types and situations that create them. The rule is learned as a list rather than as a hierarchy of rules.

What to do instead

Build a decision tree you can recite: first check for signals (police, lights, signs), then road type (priority road, main road, dirt track), then trams, then the default right-before-left. Practise by naming, for each of ten junctions you know, which level of the tree decides it.

Mistake 2

Reading a sign's shape and colour but not its exact symbol or supplementary plate, for example missing the distance or direction arrow on a priority-road sign, or missing the exemption plate under a prohibition sign.

Under time pressure the eye categorises signs by silhouette (triangle = danger, circle = prohibition) and skips the detail. In Switzerland, many signs are only distinguishable by small supplementary plates.

What to do instead

On every practice run, say aloud the full content of each sign: shape, colour, symbol, and any supplementary plate. Drill sets of signs that share a silhouette but differ in symbol or plate until the detail becomes the first thing you notice.

Mistake 3

Confusing the meaning of road markings with the meaning of signs, for example treating a broken white line as a permission to cross without checking for a solid line further ahead, or misreading yellow markings that indicate bus lanes, parking restrictions or construction zones.

Markings are learned as a decorative background rather than as binding rules, and yellow markings in particular are less familiar because they appear less often in everyday riding.

What to do instead

Learn markings by function: longitudinal lines (crossing rules), transverse lines (stop, yield), and coloured areas (yellow = restriction or temporary, white = guidance). Ride a route with construction zones and name each yellow marking and what it forbids.

Mistake 4

Underestimating stopping distance on a motorcycle by using car intuition, especially failing to account for the front brake's dominant share of braking force and for the effect of a pillion passenger or luggage on the rear.

Candidates learn the physics abstractly and never convert it into a felt number. They also brake with the rear only out of fear of locking the front, which lengthens the stop.

What to do instead

Learn the split explicitly: the front brake provides the majority of deceleration, the rear stabilises. Practise emergency stops from 50 km/h on dry tarmac, then repeat with a pillion, and note the difference in distance. Always brake in a straight line before leaning.

Mistake 5

Entering a bend too fast and then braking or rolling off the throttle mid-corner, which stands the bike up and pushes it wide toward the centre line or the outside edge.

Speed is judged at the entry point rather than for the whole curve, and the rider trusts the brake as a safety net instead of setting speed before the turn. Target fixation on the outside of the curve makes it worse.

What to do instead

Adopt a fixed sequence: brake and select gear before the turn, look through to the exit, maintain or gently open throttle through the curve. Practise on a known curve, entering deliberately slowly and accelerating out, until the sequence is automatic.

Mistake 6

Riding in the driver's blind spot or alongside a lorry's cab, and failing to anticipate that a turning lorry sweeps a wide path and can crush a motorcycle at the inner side of the turn.

Riders treat the lane as shared space and assume being seen. The blind-spot concept is understood for cars but not applied to the much larger blind zones of lorries and buses.

What to do instead

Adopt a positioning rule: never linger beside a heavy vehicle; either hang back where the driver can see you in the mirror or pass decisively and get clear. At junctions, never enter the space on the inside of a turning lorry.

Mistake 7

Failing to perform a proper shoulder check (life saver) before changing lane or position, relying only on the mirrors.

Mirrors feel sufficient and the check feels exaggerated, so it is dropped under pressure. Mirror blind spots on a motorcycle are larger than riders expect, and a shoulder check is brief but decisive.

What to do instead

Make the check a fixed part of a signal sequence: mirror, shoulder check, indicate, manoeuvre. Practise until the shoulder check precedes every lane change and every significant position change, including before a turn.

Mistake 8

Following too closely, especially behind a vehicle that blocks the view ahead, and not adjusting the gap for rain, gravel, or a pillion passenger.

The two-second rule is known as a number but not applied as a dynamic quantity. Riders also close the gap to "keep up" with traffic flow.

What to do instead

Use a fixed reference point and count the time gap; double it in rain and add margin with a pillion. Position slightly offset within the lane to see past the vehicle ahead, and drop back when the view is blocked.

Mistake 9

At an accident scene, moving an injured motorcyclist without necessity, or removing the helmet, instead of securing the scene, calling for help, and providing first aid in place.

The instinct to help physically overrides the protocol. Candidates also underestimate the risk of a spinal injury after a motorcycle crash and the danger of the scene itself.

What to do instead

Learn the order as a fixed sequence: secure the scene (warning triangle, hazard lights, high-visibility), alert emergency services with location and number of casualties, then provide first aid. Do not remove the helmet or move the casualty unless there is an immediate danger such as fire.

Mistake 10

Riding in a way that wastes fuel and increases emissions: holding high revs in a low gear, harsh acceleration and braking, excessive idling, and carrying unnecessary load or a badly adjusted chain and tyre pressures.

Economical riding is treated as a theoretical topic rather than a riding style, and riders do not connect maintenance state (tyre pressure, chain tension, brake drag) to fuel consumption and safety.

What to do instead

Ride in the highest gear that pulls cleanly, accelerate smoothly, use engine braking and anticipation instead of late braking, and switch off the engine during long waits. Check tyre pressures and chain tension weekly, since both affect consumption and handling.
