China Driving Subject 4 (Motorcycle) common mistakes
China Driving Subject 4 (Motorcycle) · Understand the traps and how to avoid them.
Treating a flashing yellow light the same as a green light and riding through without slowing or checking the intersection.
Candidates memorize the three solid colours and lump flashing signals into 'go' categories, forgetting that a flashing yellow means proceed with caution after yielding to traffic already in the intersection and to pedestrians.
What to do instead
Build a small table of every signal variant (solid red, flashing red, solid yellow, flashing yellow, green arrow, flashing green arrow) and for each write the required action and the right-of-way rule. Drill until a flashing yellow triggers an automatic 'slow, look, yield' response rather than 'go'.
Reading a road marking in isolation and ignoring the sign or signal above it, for example crossing a solid white edge line to overtake because no sign appears to forbid it.
Markings and signs are studied as separate chapters, so candidates do not form the habit of combining all three channels (sign, marking, signal) at one location before deciding.
What to do instead
Practise 'layered reading' of each scene: identify the sign, then the marking, then the signal, then decide. When any one of them prohibits a manoeuvre, the prohibition applies. Do timed exercises where you must name all three cues before answering.
Assuming a motorcycle's shorter stopping distance means it can safely follow a car at a shorter gap on wet or gravelly roads.
Riders over-trust the bike's agility and forget that a two-wheeler has only two small contact patches, and that a fall removes the protection a car body would provide. The habit is carried over from dry-road riding.
What to do instead
Apply a fixed following-distance rule: at least two seconds in good conditions and four seconds or more in rain, at night, or on unfamiliar roads. Rehearse counting the gap to a roadside marker and adjust before the ride, not during it.
Braking hard with the front brake only in an emergency, or grabbing the brake lever abruptly.
Panic narrows attention, and the instinctive grab feels like 'maximum braking'. Candidates also believe the front brake alone is strongest and skip coordinated use of both brakes.
What to do instead
Learn and rehearse progressive, coordinated braking: both brakes together, front pressure building smoothly, rear applied lightly to stabilise. Practise emergency stops from 40 km/h in a safe empty area until the motion is automatic, and keep the bike upright with the bars straight.
Leaving the scene of a minor collision because 'no one was hurt and the bike is fine'.
Candidates confuse the duty to stop with serious-injury scenarios and do not know that stopping, protecting the scene, and exchanging information is required regardless of damage.
What to do instead
Memorise the accident-response sequence as a fixed checklist: stop and secure the scene, warn other traffic, check for injuries and call emergency services, report to traffic police, exchange details, and only then leave. Recite the sequence until it is automatic.
Failing to place a warning triangle or other warning device when a motorcycle breaks down or crashes on a road.
Riders think a small vehicle is easy to see and skip the warning step, or they do not know where the device should be placed relative to the vehicle and traffic flow.
What to do instead
Learn the rule that a warning device must be set at a sufficient distance behind the vehicle on the same lane or shoulder so approaching drivers have time to react, and that hazard lights and high-visibility clothing should be used at night. Rehearse the placement distance for urban and highway speeds.
Riding at normal speed into fog, heavy rain, or a flooded section, relying on the headlight alone.
Candidates underestimate how much visibility and grip drop in bad weather and do not know that standing water can hide depth and cause a wobble or stall.
What to do instead
Adopt a weather rule set: reduce speed substantially, increase the gap, use low beam (not high beam, which reflects back in fog), avoid sudden braking or steering on wet paint and metal covers, and if water depth is uncertain, stop and check before crossing. Practise identifying these hazards in scenario questions.
Weaving between lanes or filtering to the front at a red light and treating it as normal riding.
Candidates see experienced riders do it and assume it is legal and safe, and they underestimate how a car driver's blind spot and unexpected lane change can trap a filtering motorcycle.
What to do instead
Learn the specific rules on lane use and overtaking for motorcycles, and treat lane changes as a full manoeuvre: signal, mirror, shoulder check, then move. In queued traffic, hold a position visible in a mirror rather than in a blind spot.
Memorising penalty amounts and demerit points as isolated numbers without linking them to the conduct that triggers them.
Candidates cram tables of fines and points the night before and cannot map a described behaviour to the correct penalty under exam pressure.
What to do instead
Build a two-column list: behaviour on the left, penalty and points on the right, and group behaviours by theme (drink-riding, speeding, licence offences, helmet offences). Test yourself by reading only the behaviour and recalling the penalty, then reverse the direction.
Skipping the pre-ride check and assuming a motorcycle that starts and rolls is roadworthy.
The bike is small and familiar, so riders check only fuel and tyres under pressure, ignoring brakes, lights, chain tension, mirrors, and fluid levels that fail gradually rather than suddenly.
What to do instead
Use a fixed pre-ride walk-around: tyres and pressures, both brakes, lights and indicators, horn, mirrors, chain or belt tension and lubrication, fluid levels, and a check that the stand retracts. Make it a 60-second routine performed every time, not only before long trips.
