What are the quick memorization tips for Subject 4 knowledge points?

Subject 4 knowledge points are numerous and varied, so they should be memorized by category. Below are detailed classifications: Lighting: Adverse weather conditions: Temporary parking during nighttime, rainy, foggy, or snowy conditions requires turning on hazard warning lights, clearance lights, and rear position lights. When driving in fog, turn on fog lights and hazard warning lights. Nighttime driving: If the headlights illuminate off the road, it could indicate a sharp turn or large pothole ahead. When approaching a curve at night, the headlights will shift from the center to the side of the road. Roundabouts: Do not use turn signals when entering a roundabout. Use the right turn signal when exiting. Alternating high and low beams: When driving at night, use alternating high and low beams only for "overtaking, intersections, and crosswalks." In all other situations, use low beams. Switching from high to low beams: When turning, changing lanes, overtaking, making a U-turn, or parking on the roadside, switch from high beams to low beams at least 150 meters away from oncoming vehicles. Streetlight conditions: Use low beams when streetlights provide good illumination at night. Use high beams when streetlight illumination is poor. Speed and lighting: Use low beams when driving below 30 km/h. Use high beams when driving above 30 km/h. Highway tunnels: Turn on headlights when approaching a highway tunnel entrance within 50 meters. Distance restrictions: Vehicle breakdown on the road: If a vehicle breaks down during the day or night and is difficult to move, turn on hazard warning lights and place a warning sign 50–100 meters behind the vehicle. Breakdown on the highway: Turn on hazard warning lights and place a warning sign 150 meters behind the vehicle (except in heavy fog). Highway following distance: Maintain a distance of at least 100 meters when driving above 100 km/h. When driving below 100 km/h, the minimum distance should be no less than 50 meters. Meeting vehicles: Uphill and downhill: On icy or snowy roads, the downhill vehicle has the right of way. In all other cases, the uphill vehicle has the right of way. Roundabouts and tunnel entrances: Vehicles entering must yield to those exiting. Intersection priority: Straight-moving vehicles have priority but must yield to vehicles from the right. Vehicles with obstacles yield to those without. Right-turning vehicles yield to left-turning vehicles. No parking zones: Do not park within 30 meters of bus stops, emergency stations, gas stations, or fire hydrants. Do not park within 50 meters of intersections, tunnels, steep slopes, sharp turns, or narrow roads. Safe distances: On rainy days, maintain a longitudinal safe distance 1.5 times the usual distance. On snowy or icy days, maintain a distance 3 times the usual distance (applies to both highways and regular roads). Road construction: Place reflective signs at least 50 meters away during the day and 100 meters away at night. Same-direction highway lanes: Two-lane highway: The left lane has a minimum speed of 100 km/h, and the right lane has a minimum speed of 60 km/h. Three-lane highway: The left lane has a minimum speed of 110 km/h, the middle lane has a minimum speed of 90 km/h, and the right lane has a minimum speed of 60 km/h. Four-lane highway: The far-left lane has a minimum speed of 110 km/h, the middle two lanes have speeds of 90–110 km/h, and the far-right lane has a minimum speed of 60 km/h. If a vehicle reaches 110 km/h or more, it should drive in the far-left lane. Acceleration lane: When entering a highway acceleration lane, accelerate to at least 60 km/h as quickly as possible.
When it comes to memorization techniques for Subject 4 (theoretical driving test), I believe the most important thing is to visualize traffic rules. During my revision, I specifically took photos of various road markings with my phone. Basics like stopping at red lights and going at green lights go without saying—the real challenge lies in remembering those special scenarios: for example, seeing a diamond-shaped pavement marking means you should slow down in advance, while encountering yellow-and-black vertical markings should immediately remind you of curves or slopes. For the most easily confused traffic police hand signals, I pretended to be a traffic officer and mimicked the gestures: an outstretched arm means go straight, and a left arm swinging in a circular motion indicates a lane change. As for nighttime driving light questions, I memorized three key phrases: use high beams when there are no streetlights, switch to low beams when meeting another vehicle within 150 meters, and never use high beams when following another car. My advice is to create a separate album for your incorrect questions and review these images repeatedly three days before the exam—it’s much more efficient than rote memorization.
