What to Do If You Fail the Driver's License Test?

Is the Prado Air Suspension Useful?

The Prado air suspension is useful. A high-quality SUV must combine the comfort of a sedan with the off-road capability of an SUV, and the air suspension system is the best choice to achieve this goal. Here is more information about the air suspension system: 1. Generally, vehicles equipped with air-adjustable suspension will have ground clearance sensors near the front and rear wheels. Based on the output signals from these sensors, the vehicle's computer determines changes in body height and then controls the air compressor and exhaust valves to automatically compress or extend the springs, thereby lowering or raising the chassis ground clearance. This enhances high-speed stability or improves off-road capability on rough terrain. 2. The air suspension can adjust the stiffness of the car's chassis by controlling air pressure, so high-end models that prioritize both comfort and handling often opt for air suspension. This meets consumer demands in the most reasonable way. 3. Air suspension is also used in sports cars. However, in sports cars, its purpose is not to adjust comfort but to achieve the ultimate handling performance and address some daily inconveniences, such as raising the chassis height when crossing speed bumps. 4. The air suspension can be manually adjusted, and its definition varies depending on the vehicle model. Suspension adjustments are typically made by the driver via center console buttons, or the suspension adjusts automatically based on driving speed. Alternatively, the vehicle may adjust suspension stiffness based on data from related sensors, significantly improving handling and ride comfort.

How to Deal with Excessive Interior Noise in a Car?

There are four solutions to car noise: 1. Engine Noise: The vehicle engine is a source of noise, and its noise production varies with the engine speed. Solution: High-grade sound-absorbing foam materials can be installed on the engine hood, which not only suppresses vibrations caused by the hood but also absorbs a significant amount of noise, with noticeable effects. 2. Tire Noise: Tire noise is generated by the friction between the tires and the road surface during high-speed driving. The level of tire noise depends on road and vehicle conditions; worse road conditions result in louder tire noise. Additionally, there is a significant difference in tire noise between asphalt and concrete roads. Solution: Tire noise is a type of structural noise, primarily caused by vibrations. The most reasonable solution is vibration damping. Adding damping plates along with sound-absorbing mats can effectively address road and tire noise. 3. Wind Noise: Wind noise occurs when the pressure of the wind encountered during high-speed driving exceeds the sealing resistance of the car doors, allowing it to enter the interior. The faster the driving speed, the louder the wind noise. Solution: Install or replace door sealing strips. Since sealing strips are rubber products, they can age over time, leading to reduced sound insulation and sealing effectiveness. 4. Body Structure Noise: This is mainly influenced by two factors: the vibration transmission method of the body structure and the noise generated by metal components of the body under internal and external forces. Solution: This issue rarely occurs in new cars. It is important to check whether the screws of body components have become loose. Generally, tightening the screws or replacing the parts can resolve the problem.

What is the tire model of the Kia Cerato?

Dongfeng Yueda Kia Cerato uses Kumho tires, and the tire model is Kumho KH18-195/60R15 88H. Here is more information about this tire: 1. KH18 - refers to a series model of Kumho tires. 2. 195 - indicates that the tread width of the tire is 195mm. 3. 60 - represents the aspect ratio, meaning the section height is 60% of the width. 4. R - indicates that the tire is a radial tire. 5. 15 - shows the rim diameter is 15 inches. 6. 88 - stands for the load index 88, meaning the maximum load capacity of this tire is 560 kg. 7. H - represents the speed rating of 210 km/h. Tips for using tires: (1) When driving uphill, try to use inertia to drive, shift gears timely, and maintain appropriate reserve power for the vehicle. Do not wait until the car stops to start again, so as to reduce tire wear. (2) When turning, control the speed according to the curve conditions. Do not turn at high speed, otherwise the vehicle will generate a large centrifugal force, causing the cargo to tilt and the center of gravity to shift to one side, overloading and dragging a single tire, accelerating wear. At the same time, the tire may be laterally cut by the wheel rim, causing damage.

What is the original tire size of the Highlander?

The Highlander comes with two original tire size specifications: 235/65R18 and 235/55R20. In 235/65R18, the first number 235 represents the tire width of 235MM, 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width, and 18 stands for the rim diameter of 18 inches. The letter "R" in the middle denotes a radial tire. In 235/55R20, the first number 235 represents the tire width of 235MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 20 stands for the rim diameter of 20 inches. The letter "R" in the middle denotes a radial tire. The Elite trim of the Highlander is equipped with 18-inch aluminum alloy wheels, featuring a robust and simple five-spoke silver design, paired with Dunlop SP-SPOORT-MAXX-050 series tires. The Premium and Platinum trims use identical 20-inch aluminum alloy wheels with slender silver-gray multi-spoke combinations, matched with Yokohama BluEarth-XT series or Dunlop SP-SPOORTMAXX-050 series tires. If you wish to replace the tires yourself, follow these steps: Retrieve the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack contacts the metal part of the frame; Raise the jack until it supports the car, making sure the jack is positioned under the vehicle and at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise without fully removing them, just enough to eliminate resistance. Keeping the tire on the ground when first loosening the nuts ensures the nuts turn instead of the tire; Turn the nuts counterclockwise until they are loose, repeat this for all lug nuts, then remove them completely; Place the new tire on the hub, carefully aligning the tire rim with the wheel bolts, install the lug nuts, and hand-tighten them until all nuts are snug. The tire replacement is now complete. Besides the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed the tire can carry a specified load under specified conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Shows the rim size compatible with the tire for practical use, such as "Standard rim 5.00F".

Do You Need to Press the Clutch When Making a U-Turn?

If there are no other vehicles affecting the U-turn, you don't need to press the clutch, and the U-turn action should be completed quickly. If there are straight-moving vehicles in the opposite lane, you need to press the clutch and brake pedal to perform a braking operation, allowing the straight-moving vehicles to go first. Otherwise, the U-turn vehicle will bear full responsibility in case of an accident. Situations where U-turns are allowed: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn can be made. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, make the U-turn based on the specific situation without obstructing other vehicles or pedestrians. Intersections without explicit no-U-turn or no-left-turn signs: If there is no explicit prohibition of U-turns, you can make a U-turn. 'No explicit prohibition' means the intersection lacks 'no U-turn signs,' 'no left-turn signs,' or solid center lines, allowing a U-turn. Yellow grid lines also allow U-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary parking, important unit entrances, and other necessary locations. Stopping on these lines (including waiting for traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed as long as there is no central barrier, making it equivalent to 'U-turn permitted.' Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, proceed only when it's green. No-left-turn and U-turn-permitted signs appearing together: U-turns are allowed, but left turns are prohibited. However, 'no U-turn' is not the same as 'no left turn.' Precautions when making a U-turn at an intersection: Observe road markings. If there are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn spot. If there is a 'no left turn' sign, even without a 'no U-turn' sign, U-turns are not allowed at that intersection because U-turns and left turns are similar maneuvers, and U-turns always involve a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at that intersection. Always yield to straight-moving vehicles and make the U-turn only if it doesn't interfere with their normal flow. Otherwise, you will bear full responsibility for any accident. Near the intersection stop line, lanes usually have guiding arrows for vehicle direction. The leftmost lane may not always have a left-turn arrow. On some roads, if there is a straight arrow, U-turns are prohibited even without explicit 'no U-turn' signs. Making a U-turn on a crosswalk is also a traffic violation.

How Many Chances Are There for Subject One?

The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" clearly stipulate that on the day of the Subject One exam, you can take the test twice. If you fail the first time, you can retake it for free the second time. If you still fail the second time, the Subject One exam for this session will be terminated, and you can only schedule the exam again after ten days. Subject One, also known as the Subject One theory test or driver theory test, is part of the motor vehicle driver's license assessment. The exam content includes the theoretical basis of driving, road safety laws and regulations, local regulations, and other related knowledge. The exam format is computer-based, with a limited time of 45 minutes. For the driver's license Subject One exam, a score of 90 is required to pass. There are 100 questions, divided into single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If you answer 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. Subject One exam content: Driver's license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject One exam precautions: During the Subject One exam, students should pay attention to their attire. No slippers are allowed, and electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in the locker before entering the exam room. Upon entering the exam room, the identity verification station will assign a seat. After finding your seat, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail once, you can retake the exam on the same day. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it. Failure to sign will render the score invalid. There is no limit to the number of times you can schedule the Subject One exam. Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail the retake, the exam for this session will be terminated, and the applicant must reschedule the exam. For Subject Two and Subject Three, there are only five exam attempts. Subject Two and Subject Three exams can be scheduled ten days later. If you fail the Subject Three safe driving knowledge test, the previously passed road driving skills test score remains valid. There are three subjects in the driver's license exam: Subject One, Subject Two, and Subject Three. Subject One refers to the road traffic safety laws, regulations, and related knowledge exam. Subject Two refers to the field driving skills exam. Subject Three is divided into two parts: road driving skills and safe driving knowledge exam. The safe driving knowledge test is conducted after Subject Three, so it is commonly referred to as Subject Four. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as Subject Four.
