Can a 3-meter-wide road make a right-angle turn?

Roads with a width of 3 meters cannot make right-angle turns. Right-angle turn: A right-angle turn is an assessment point in Subject 2 of the driver's test, evaluating the driver's ability to correctly manipulate steering and accurately judge the inner and outer wheel differences when driving through sharp turns. Engage first gear, release the handbrake, slowly lift the clutch to maintain semi-engagement for smooth forward movement, and keep the left wiper's left dot (the first rivet) aligned with the right edge of the road's yellow line at a 20 cm distance. Then, focus on a point slightly ahead of the middle door lock on the left front door of the car. Deduction points: Touching the protruding point with the wheels results in failure; each time the wheels touch the road edge line, 20 points are deducted; completing the maneuver with reverse gear results in a 10-point deduction. Failing to use turn signals or using them incorrectly results in a 10-point deduction.

What causes the CR-V to shake when the AC is on but not when it's off?

CR-V shaking when the AC is on is generally caused by carbon buildup on the spark plugs, carbon buildup on the throttle body, or fan deformation/screw loosening. Below are detailed explanations of the reasons for car shaking when the AC is on: 1. Spark plug carbon buildup: After some time of vehicle use, spark plugs accumulate carbon deposits. If not cleaned promptly, this can reduce engine torque output, causing shaking when the AC is activated. Soak the spark plugs in white vinegar for 2-3 hours (4-5 hours for severe cases), then scrub with a stiff brush to remove carbon deposits. Clean with gasoline and air dry. 2. Throttle body carbon buildup: When the AC activates, the sudden increase in engine load requires greater throttle opening. Existing carbon deposits then cause throttle sticking or improper opening, restricting air intake and reducing engine power, ultimately manifesting as engine vibration. 3. Fan deformation or screw loosening: Check whether resonance occurs during fan operation after AC activation due to fan deformation, or whether vibrations are caused by loose fan mounting screws.

What Causes a Car Steering Wheel to Shake Left and Right?

Steering wheel shaking is primarily due to lack of lubrication or component damage. Causes of car steering wheel shaking: Lack of lubricating oil in the shock absorber plane bearing; Loose or damaged stabilizer bar bushings; Lack of lubricating oil in the steering column dust cover; Lack of lubricating oil or damage to the steering wheel airbag clock spring. The steering wheel is a wheel-shaped device that controls the driving direction, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. Solutions: Apply grease to the plane bearing or replace it; Add shims to the stabilizer bar bushings; Apply grease inside the dust cover; Remove the steering wheel's airbag clock spring, apply grease, or replace it.

What are the screen functions of the Inspire Delicate Edition?

inspire Delicate Edition screen features include Vehicle Stability Control, Hazard Warning Lights, Auto Hold, and Air Recirculation functions. Auto Hold function: In situations like traffic lights where the vehicle stops, after releasing the brake pedal, the Auto Hold function will lock the wheels, relieving the driver's foot fatigue. When the driver presses the accelerator pedal again, the electronic parking will unlock the wheels. Air Recirculation function: Air Recirculation means heating or cooling the air inside the car and then sending it back into the cabin, while Fresh Air mode allows outside air to enter the car. During traffic jams, in tunnels, or when the outside air quality does not meet standards, prioritize using Air Recirculation. On highways, switch to Fresh Air mode periodically to ventilate the cabin and prevent health issues caused by stale air.

How many bottles of fuel additive should be added each time?

Usually, the initial use requires 2 bottles, followed by 1 bottle for subsequent uses. Fuel additive usage: Fuel additives are unnecessary for new vehicles with less than 20,000 kilometers of mileage. For vehicles exceeding 20,000 kilometers, they should be added as needed, typically one small bottle per tank of fuel. Long-term use of fuel additives can be harmful to the engine. Excessive use can increase carbon deposits in the combustion chamber, and prolonged overuse may even lead to engine knocking, detonation, and worsened vehicle emissions. Precautions: New vehicles are not recommended for fuel additive use, as they have not been driven many kilometers and generally operate under good conditions, with minimal carbon deposits. Frequent use of fuel additives is not advisable, as it can lead to oil sludge, gum formation, and increased carbon deposits in the combustion chamber. Instead, additives should be used based on the vehicle's specific conditions. For severe carbon deposits, manual cleaning is still necessary. Fuel additives are not a miracle solution; vehicles with heavy carbon buildup require manual treatment, as additives cannot completely remove them. For older vehicles, the oil filter should be cleaned or replaced before adding fuel additives. Use fuel additives cautiously and rationally according to the vehicle's condition.

Does Only Capturing the Front Count as Driving Against Traffic?

Generally, driving against traffic requires capturing both the front and rear license plate numbers in two images to be considered a traffic violation. Principle of Capturing Driving Against Traffic: Typically, there are two vehicle detection loop sensors installed at the front and rear of the motor vehicle lane—Sensor 1 and Sensor 2. Normally, vehicles should pass Sensor 1 first, followed by Sensor 2, which does not trigger the electronic police to take photos. If a vehicle is driving against traffic, it will pass Sensor 2 first, then Sensor 1, reversing the normal sequence, which triggers the electronic police to capture images. Determination of Driving Against Traffic: On roads with solid dividing lines (double solid lines or single solid lines), vehicles must not cross the line under any circumstances. If a motor vehicle enters the opposite lane, it is considered driving against traffic. On roads with dashed dividing lines, vehicles may overtake by borrowing the opposite lane if it is safe, but in the event of an accident, the borrowing vehicle will be deemed to be driving against traffic. On roads with one-way signs, any motor vehicle entering is considered to be driving against traffic.
