Korea Class 1 Written Test common mistakes
Korea Class 1 Written Test · Understand the traps and how to avoid them.
Answering penalty-point questions by recalling the general fine amount instead of separating the administrative fine (범칙금) from the criminal penalty points (벌점) attached to each violation.
Candidates memorize one number per offence from news or hearsay, and the exam deliberately pairs a violation with both a fine and a point total, so the single memorized number maps to the wrong field.
What to do instead
Build a two-column table per violation type (fine / penalty points) and drill it in both directions: given the points, name the violation; given the violation, state the points. Treat 40 points as the licence-cancellation threshold and 121 points as the suspension threshold, and check which threshold the question is asking about before answering.
Treating a yellow flashing signal or a police officer's hand signal as subordinate to the traffic light, or assuming the light always wins.
Everyday driving creates a habit of watching only the light head; the exam tests the priority order (officer > signal > sign > markings) with scenarios where the officer contradicts the light.
What to do instead
Memorize the fixed priority chain and practise applying it to short scenarios: officer's signal first, then traffic signal, then road sign, then road markings. For flashing yellow, answer 'proceed with caution after yielding' rather than 'stop' or 'go freely'.
Choosing the 'safest-sounding' action on defensive-driving items, such as always stopping dead or always honking, instead of the action the specific hazard calls for.
The items are written so that two options are both safe in the abstract; candidates pick by emotional appeal rather than by the hazard-perception sequence the exam rewards.
What to do instead
Answer using the sequence predict-predict-act: identify the hidden hazard (child behind a parked car, car door opening, wet leaf patch), then select the option that reduces speed and increases lateral margin before the hazard, not the option that reacts after it. Reject options that add noise or a sudden stop in fast traffic.
Ignoring following-distance and stopping-distance numbers, answering 'keep a safe distance' when the item asks for a specific metre value at a given speed.
Candidates learn the concept but not the arithmetic, and the exam converts speed into reaction distance plus braking distance using a stated reaction time.
What to do instead
Learn the formula (reaction distance = speed in m/s × reaction time; add braking distance) and practise with 60 km/h and 100 km/h cases, including wet-road multipliers. When a numeric option is offered, compute it rather than choosing the qualitative one.
Confusing warning-light meanings, particularly the engine oil pressure lamp, the coolant temperature lamp, and the battery charge lamp, and driving on after one illuminates.
The symbols look similar and are rarely seen in normal driving, so candidates guess by colour alone (red = stop, amber = caution) without knowing which system each icon represents.
What to do instead
Group lamps by consequence: oil pressure and coolant temperature are stop-immediately red lamps; battery charge is a red lamp meaning the alternator is not charging; ABS and tyre-pressure lamps are amber and allow a cautious limp to a workshop. Match each icon to its system name and its required action.
Answering tyre and brake inspection items by tread depth alone, forgetting the legal minimum, sidewall damage, and the difference between tread wear indicators and actual measurement.
Candidates reduce inspection to 'check the tyres' and never fix the numeric legal minimum or the list of disqualifying damage in memory.
What to do instead
Memorize the legal minimum tread depth, the tread wear indicator meaning, and the disqualifying conditions (cord exposed, bulge, deep cut, embedded object, uneven wear). For brakes, learn the check items: pedal free play, fluid level, pad thickness, and pulling to one side under braking.
Leaving the scene or moving the vehicle after a collision without first securing the scene, or conversely insisting on preserving the position when someone is injured.
Candidates conflate 'do not move the vehicle' with 'do not act', and the exam tests the priority order of rescue, secondary-accident prevention, and reporting.
What to do instead
Fix the order in memory: stop, switch on hazard lights and place the warning triangle, check for injuries and call emergency services, then report to police. Move the vehicle only when no one is injured and traffic safety requires it, and record the position first.
Mishandling the first-aid items, such as giving food or water to an unconscious casualty, removing a helmet from a motorcycle rider, or moving a suspected spinal injury.
Candidates answer from everyday instinct ('help them sit up, give water') rather than from first-aid protocol, and the exam offers those instinctive options as distractors.
What to do instead
Learn the do-not list: do not give food or drink to an unconscious person, do not remove a helmet unless breathing is obstructed, do not move a suspected spinal casualty unless there is fire or traffic danger. Learn the correct sequence: check responsiveness and breathing, call for help, control bleeding with direct pressure, begin CPR if breathing has stopped.
Mixing up licence suspension and cancellation thresholds and the point totals that trigger each, or confusing the penalty-point system with the fine system.
Both thresholds are numbers in the same range and candidates learn them as a pair without anchoring which is which, so under exam pressure the two swap.
What to do instead
Anchor the numbers to their consequence: 40 points in one year means cancellation, 121 points accumulated means suspension, and the suspension escalates with repeat accumulation. Write the pair on one line with the consequence attached and rehearse it aloud before the test.
Treating eco-friendly driving items as trivia about vehicle technology rather than as a list of driving behaviours with measurable effects, and picking 'buy an electric car' style answers.
Candidates read the domain as environmental science and overlook that the exam rewards concrete habits: steady speed, early gear shifts, avoiding idling, correct tyre pressure, and removing unnecessary load.
What to do instead
Convert the domain into a behaviour checklist and link each habit to its effect: idling for more than a short wait wastes fuel, under-inflated tyres raise rolling resistance, harsh acceleration raises consumption sharply, and air-conditioner use adds load. Answer with the driving behaviour, not the purchase decision.
