Can You Still Drive a Car with a Flat Tire?

You should not continue driving with a flat tire. Here are the relevant details: Hazards of a flat tire: Continuing to drive with a flat tire can cause significant damage to the vehicle's suspension, transmission, and other systems, and may also deform the wheel rim. Most importantly, it endangers personal safety. As the tire loses its support, the stability of the vehicle body severely decreases, making it highly prone to traffic accidents. Therefore, the immediate priority is to slow down gradually and park the car in a relatively safe place to replace the spare tire or call for assistance. Run-flat tires in case of a flat: Of course, run-flat tires offer relatively higher safety. Even after a flat, they do not lose pressure instantly like regular tires. Their sturdy sidewalls can support the car to drive at speeds below 80km/h for about 80 kilometers. However, it's important to note that if the damage area of the run-flat tire is too large, you should not continue driving as it still poses certain safety risks.

Can You Still Drive When the Exhaust Malfunction Light Is On?

When the exhaust malfunction light is on, you can still continue driving. Not all exhaust malfunction lights indicate that the vehicle cannot be driven. If the engine malfunction light is on, there are no abnormal noises in the engine compartment, no other abnormal warnings on the dashboard, the vehicle's power is unaffected, and the transmission shifts normally, you can continue driving to a 4S shop for further diagnosis. Issues such as intake or exhaust problems may trigger the engine malfunction light. Introduction: This commonly referred to exhaust malfunction light is also known as the fuel injection system malfunction light. As long as there are no unusual changes in engine power or sound, you can continue driving. This is because the ECU (Engine Control Unit) has a fault substitution program. If any sensor among the many sensors fails, the ECU will use pre-set backup parameters to replace the faulty sensor's data to prevent the vehicle from stalling. For example, if the coolant temperature sensor fails, the ECU will use a backup value of 80 degrees Celsius as the control parameter for fuel injection and ignition. Therefore, while driving is possible, timely repairs are still necessary. If not addressed promptly, the following issues may arise: Deterioration in exhaust gas quality, leading to environmental pollution; increased fuel consumption; elevated combustion chamber temperature and accelerated wear, causing faster engine deterioration; increased engine noise, affecting driving and passenger comfort.

What is the Hand Signal for Prohibiting Forward Vehicle Movement?

The hand signal for prohibiting forward vehicle movement is to extend the left arm straight upward with the palm facing forward. Below is relevant information about the passing scores for the driver's license test: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. It is a written test conducted on a computer, with a full score of 100. A score of 90 or above (including 90) is required to pass. 2. Subject 2: Field driving skills test. It is a practical test conducted in a designated area, with only pass or fail results. The test includes five mandatory items performed in sequence: reversing into a parking space, parallel parking, S-curve driving, right-angle turning, and hill start and stop. The full score is 100, and a score of 80 or above (including 80) is required to pass. 3. Subject 3: Road driving skills test. It is a practical test conducted on a road or simulated area, with a full score of 100. For large buses, a score of 90 or above is required to pass; for large trucks, 80 or above; and for other vehicle types, 70 or above. 4. Subject 4: Safe and civilized driving knowledge test. It is a written test with a full score of 100, and a score of 90 or above (including 90) is required to pass.

What is a Sequential Transmission?

Sequential transmission refers to a manual gearbox that shifts gears in a sequential order. Its input shaft is directly connected to the engine, eliminating redundant gear-shifting transmission structures, making its design simpler, more compact, and faster in shifting with reduced chances of mis-shifting. Differences between sequential and manual transmissions: Nature: The sequential transmission differs from a regular manual transmission primarily in its operation method—shifting up or down is achieved simply by pushing or pulling the gear lever forward or backward. In contrast, a manual transmission requires manually moving the gear lever to change the gear engagement positions inside the transmission, altering the gear ratio to achieve speed changes. Features: The existence of a manual transmission is determined by the physical characteristics of the engine, as every engine has its peak RPM. Additionally, the engine's maximum power and torque occur within a specific RPM range. In a sequential transmission, all shifting operations can be entirely controlled by a computer, allowing the driver to complete gear shifts effortlessly without using the clutch pedal, even in 'S' mode, where all that's needed is to push or pull the gear lever. Operational Setup: In a sequential transmission, the combination of a shift drum and straight-cut gears enables trained drivers to switch gears without operating the clutch pedal. In a manual transmission, the gears (blue) rotate freely on the splined shaft. When the engine is off but the vehicle is still moving, both the gears (blue) and the countershaft remain stationary, while the splined shaft continues to rotate with the wheels.

What Are the Essential Items for Driving?

Daily driving essentials in the car include a vehicle tool kit, spare tire, first aid kit, jack, original car manual, etc. Vehicle Tool Kit: Every car comes with a tool kit, which usually contains basic tools such as wrenches, screwdrivers, and wheel nut wrenches. Owners should regularly organize and inspect it, preferably cleaning and maintaining the tools after each use to extend their lifespan. Spare Tire: The spare tire is often forgotten in the trunk and lacks maintenance. Therefore, it is recommended that owners check the spare tire every three months and inflate it if necessary. First Aid Kit: This is an emergency item that most drivers do not carry. In Audi cars, for example, you can find a factory-equipped first aid kit. The kit should contain bandages, gauze, disinfectant, and other emergency medications to provide first aid in case of an accident. Additionally, the first aid kit should be checked and replenished every six months. Jack: The jack is an indispensable tool for changing tires. Almost all car manufacturers include a jack with the vehicle. When buying a used car, be sure to check if the jack is in good condition, as the original factory-supplied jack is lightweight and easy to use. Original Car Manual: Keeping the manual in the car long-term allows you to clearly understand the vehicle's various conditions. When a problem arises, you can immediately refer to the manual to identify the cause.
