It is advisable to perform maintenance before the annual inspection, including changing the engine oil, oil filter, and air filter, checking the driving system, braking system, steering system, and power system, replenishing any insufficient fluids, inspecting various electrical equipment, and checking for any rust or damage on the vehicle's exterior. The items tested during the annual inspection and situations that may cause the vehicle to fail the inspection are as follows: Items tested during the annual inspection: If an on-site inspection is required, the vehicle must be driven onto the inspection line. On the inspection line, the vehicle's braking system, lighting system, exhaust emissions, chassis, etc., will be tested. Situations that may cause the vehicle to fail the inspection: If any test item does not meet the standards, the vehicle will not pass the annual inspection. During the on-site inspection, it is also necessary to bring the vehicle registration certificate, compulsory traffic insurance policy, and the owner's ID card.

From my years of driving experience, getting a minor service before the annual inspection is quite necessary. It's not mandatory, but it saves a lot of hassle. The inspection checks brakes, lights, emissions, and other areas—if neglected, these components might fail, causing repeated trips to the repair shop. Last year, I changed the oil in advance and checked the tire pressure, passing the inspection in one go. Simple steps like cleaning dust and ensuring emissions compliance can prevent bigger issues at a small cost. A neighbor skipped maintenance, failed due to a faulty brake light, and spent the whole day fixing it. Now, I make it a habit to book a mechanic before each annual inspection to ensure safety and save time.

Why Can I Still Schedule the Subject Four Exam After It Expires?

Because the total examination period has not expired. Below is relevant information about Subject Four: 1. Concept: Subject Four, also known as the Subject Four theory test or driver's theory examination, is part of the motor vehicle driver's license assessment. 2. Retake Instructions: Failing Subject Four does not require retaking previously passed exam components (Subject One, Subject Two, Subject Three). Candidates can independently schedule retakes without paying additional fees. There are no scheduling restrictions for the safe driving theory test, but the driving skills test admission certificate remains valid for three years. If applicants fail to complete all exams within this period, their passed subject results will become invalid.

Why Won't the Car Start After Going Through a Puddle?

When a car fails to start after going through a puddle, it is usually due to water entering the engine. Here are specific solutions for dealing with a car that won't start after going through a puddle: 1. Do not attempt to restart in water: If the engine stalls while driving through water, do not try to restart it while still in the water. 2. Tow or push the vehicle out of the water: After moving the car to dry ground, try to park it on a slight incline to allow water in the exhaust pipe to drain naturally. Remove all spark plugs using specialized tools, then crank the starter to expel any water from the intake system. Once done, reinstall the spark plugs, and the car should start normally.

What are the possible causes of diesel mixing into engine oil?

When diesel mixes into engine oil, it will cause the engine oil to become thinner, resulting in changes in both its color and odor. As the oil level continues to rise, it indicates that the oil pressure is increasingly sinking due to the addition of diesel, and symptoms such as idle vibration may occur. Additional information: 1. The role of engine oil: During operation, the metal components inside the engine that undergo frictional motion move at high speeds, and the working temperature can reach 400 to 600 degrees Celsius. Given the harsh working environment of engine components, engine oil effectively reduces friction between internal parts, lowers operating temperatures, and extends the service life of components. 2. The quality of engine oil: Engines have specific requirements for engine oil, which contains elements such as sulfur and lead. The content of these elements must be controlled within certain limits; otherwise, they can accelerate the wear and tear of engine components. The quality of engine oil significantly impacts the performance and longevity of the engine.

What is the wheelbase of the Mercedes-Benz CLS?

The wheelbase of the Mercedes-Benz CLS is 2939mm, with body dimensions of 4988mm, 1890mm, and 1424mm respectively. The optional dual-control air suspension system ensures that the CLS coupe can easily navigate over bumps and uneven road surfaces. The exterior of this model features Mercedes-Benz's new family design, with a further enlarged front grille area and irregular quadrilateral LED headlights that enhance the imposing presence of the CLS front fascia. The interior maintains stylistic consistency with the new E-Class Coupe, featuring a black main theme complemented by a moderate amount of satin chrome elements.

How Does Water Get into the Transmission?

During the summer, there is more rainfall, and vehicles often drive through water. The frequency of car washing also increases. Additionally, the frequent use of air conditioning for cooling may lead to water entering the automatic transmission. Carelessness can result in automatic transmission failure. Depending on the extent of water ingress, the repair costs will vary. Related information: 1. Transmission Fluid Deterioration: Water entering the automatic transmission directly causes the transmission fluid to deteriorate and oxidize, thereby reducing its friction coefficient. This can lead to insufficient friction between vehicle components, resulting in issues such as jerking, impact, or slipping in the automatic transmission. For very minor cases, only changing the automatic transmission fluid and seals may be required. However, if some electrical components are also affected by water, the cost may increase. 2. Timely Repair: The earlier the vehicle is repaired after water ingress, the lower the cost will be. If the automatic transmission has minor water ingress and is not repaired promptly, it may lead to a series of problems over time, such as oil leaks, abnormal noises, or "jerking" issues. By the time the automatic transmission is repaired, the owner's repair costs could be 3-5 times higher than before.

What is the speed limit on ramps?

Generally, the speed limit on ramps is 40km/h, and it increases to 60km/h in sections where the ramp approaches the main highway. While driving on ramps, motor vehicles are not allowed to overtake or exceed the speed limit. Pay attention to oncoming traffic when entering or exiting ramps. Ramps, also known as access roads, are typically short adjacent auxiliary roads that provide access to main highways. Their length is determined based on factors such as traffic volume and speed on the main highway, usually ranging between 150-200 meters. They are a key component of highway interchanges. Before entering a highway ramp, drivers should reduce speed in advance and observe the speed limit signs posted alongside the ramp. Overtaking is prohibited on ramps. When approaching the junction of the ramp, do not immediately merge into the main highway, as this may result in penalties. Instead, enter the acceleration lane first to increase speed to the required level before safely merging into the main highway lane. When exiting the main highway onto a ramp, reduce speed in advance, follow ramp signage, and avoid crossing the guide lines to prevent missing the ramp exit. Once missed, drivers cannot make a U-turn and must proceed to the next exit to leave the highway.
