Key points and difficult mnemonics for the driving test Subject 4 include: common knowledge of driving preparation, common knowledge of safe driving, etc. The following are specific explanations about Subject 4: 1. Common knowledge of safe driving preparation: Traffic signs and markings, hand signals must be memorized; observe the environment before driving, check tire tightness and pressure; focus on inspecting steering and braking systems, watch for water, oil, and air leaks; maintain engine oil and cooling system, tire cracks can easily lead to blowouts. 2. Common knowledge of driving in mountainous areas: Driving in mountainous areas involves long slopes and sharp curves with many dangers; there are tricks to passing safely, reduce speed, honk, and keep to the right; increase the safe distance when following vehicles, it's best not to overtake; if encountering a fault and needing to stop, pull over in a flat section.

The year I took the Subject 4 test, I summarized a set of practical mnemonics: For lighting questions, remember 'Use low beams when following or meeting vehicles, flash alternately on sharp bends, slopes, and bridges,' and turn on fog lights plus hazard lights in foggy weather. For speed questions, memorize 'No centerline: 30 in urban areas, 40 on highways; with centerline: 50 in urban areas, 70 on highways,' and halve the speed on icy roads. For accident handling, the trick is 'First rescue the injured, then call the police, place warning signs 150 meters away,' and remember to put the triangle stand behind the vehicle. For traffic police gestures, watch the movements 'A flat palm means stop, waving indicates lane change,' and a downward left hand means slow down. For animation questions, keep your eyes peeled '80% involve unbelted drivers, with lane violations and speeding common.' Finally, a reminder: Don’t be greedy on multiple-choice questions—when in doubt, choose conservatively, as safety knowledge is always correct.

I organize the key points for Subject 4 with catchy rhymes: 'Yield to straight traffic when turning, yield to left turns when turning right; Slow down for three seconds at intersections, observe before proceeding. Park properly, remember 'three at stops, five at stations'; Don't panic during a tire blowout, gently brake and steady the wheel.' The lighting rule is simpler: 'Don't use high beams when following cars, use hazard lights and fog lights in foggy weather.' For speed limits, memorize: 'On ordinary roads without a center line, don't exceed 40 for safety; On urban single-lane roads in the same direction, 50 is just right.' Traffic police gestures are specific: parallel arms mean go straight, left arm swinging means turn left. For animations, look for violations, focusing on use and unbelted passengers; overload and speeding will definitely deduct points.'

When teaching my neighbor for the Subject 4 test, I said: Focus on three key points in the questions—memorize the speed limits: urban areas 30 for public vehicles and 40 with no centerline, 50 for public vehicles and 70 with a centerline. When visibility is 200 meters, maintain a speed of 60 and keep a 100-meter distance for safety. The lighting mnemonic is most practical: ‘Alternate flashing for sharp turns, slopes, and bridges, and never forget low beams at intersections.’ For accident handling, prioritize ‘rescuing people and stopping bleeding first, and aim the fire extinguisher at the base.’ For image-based questions, watch out for dashed and solid lines—don’t cross them, and never cross double yellow lines. For traffic police gestures, recognize left-high-right-low as the stop signal, and arm swinging indicates a turn. For multiple-choice questions, pick the confirmed options to avoid regretting point deductions for missing answers.

Sharing my tips for Subject 4: For overtaking, remember 'Overtaking from the left is compliant, slowing down and yielding is virtuous'; first aid mnemonic 'Unconscious? Lay on side to prevent choking, burns? Don't rinse with water'. Three rules for meeting vehicles: 'Downhill yields to uphill, unobstructed yields to obstructed'. Number questions often test 'Highway minimum 60 km/h, hazard signs 150 meters'. Parking distances to memorize: 'No parking within 30m of bus stops, stop 50m beyond intersections'. Animation questions focus on details: 'Check before opening doors, wait for guidance when reversing in narrow roads', most commonly overlooked is stalling at intersections without shifting to neutral. Must-remember for multiple-choice: Separate counts for violations and emergency handling, don't confuse high beam with low beam in light operations.

I passed Subject 4 with this set of mnemonics: Traffic signs are divided into three categories—yellow triangular warning signs, red circular prohibition signs with black patterns, and blue background instruction signs with white arrows. For speed classification, remember 'On two-lane highways, left lane is faster, right is slower; single-lane urban roads don’t exceed 30.' Accident handling rhyme: 'Avoid people first, then objects; on highways, brake gently in emergencies.' Lighting rules: 'Use low beams at night intersections, turn on hazard lights for temporary parking.' Traffic police gestures decoded: 'The direction the officer faces indicates which lane they’re controlling; a flat palm means go.' For animation questions, focus on 'frequent use while driving, common areas for crossing lines and speeding.' Multiple-choice strategy: 'Always select the two safest options; when in doubt, play it safe.'
