When driving a motor vehicle on muddy roads, the maximum speed must not exceed 30 kilometers per hour according to traffic laws and regulations. Relevant regulations stipulate: When a motor vehicle encounters any of the following situations, the maximum speed shall not exceed 30 kilometers per hour (for tractors, battery vehicles, and wheeled special machinery vehicles, the speed shall not exceed 15 kilometers per hour): 1. When entering or exiting non-motorized lanes, crossing railway crossings, sharp curves, narrow roads, or narrow bridges; 2. When making U-turns, turning, or descending steep slopes; 3. When encountering fog, rain, snow, dust, or hail with visibility within 50 meters; 4. When driving on icy, snowy, or muddy roads; 5. When towing a malfunctioning motor vehicle.

When driving on muddy roads, I really think you need to be careful with the maximum speed. As an experienced driver, I've had several skidding incidents on muddy terrain, and now I never exceed 40 km/h. The key issue is the slippery surface and poor tire grip—higher speeds make it easier to lose control, especially during rain or on dirt roads. My suggestion is to adjust based on vehicle type: keep regular sedans between 20-30 km/h, while SUVs or off-road vehicles can go up to 40 km/h but avoid sudden acceleration. Also, pay attention to tire condition—avoid muddy roads with worn or shallow-tread tires. During routine maintenance, check tire pressure and windshield wipers frequently to maintain clear visibility. These small habits can significantly reduce risks.

When to Straighten the Wheel When Exiting a Curve?

Straighten the wheel when the rearview mirror passes the curve corner. Below are some related tips for driving through curves: 1. Avoid stopping: When entering the curve, pay attention to the position of the front of the car. Try to keep the outer front tire close to the right edge of the curve while driving. Use the rearview mirror to judge the distance from the edge line to avoid crossing it. Proceed in first gear with the clutch partially engaged, and the speed can be slow, but stopping is not allowed. During the movement of the vehicle, observe the left and right rearview mirrors to control the distance from the edge line. 2. Pay attention to the position of the front of the car: When exiting the curve driving test area, align the front of the car with the exit, straighten the wheel, and continue driving to complete the curve driving.

Why does the car air conditioner not cool when the car is not running?

Reasons why the car air conditioner does not cool when the car is not running: 1. Insufficient battery voltage: The car air conditioner requires electricity. If the voltage is insufficient, it will not cool. When accelerating, the engine generates electricity to provide higher voltage to the battery, allowing the car air conditioner to cool normally. 2. Compressor operation status: If the compressor belt slips, it will affect power transmission, resulting in insufficient pressure at low speeds; internal components of the compressor may be damaged, causing noise, and internal wear may prevent effective compression; if the compressor clutch slips, it will also lead to insufficient compression pressure. 3. Condenser and fan status: If the condenser radiator is severely blocked, the condenser's efficiency will decrease at low speeds; check if the condenser fan is faulty—if there is noise or poor motor operation, it will affect insufficient airflow at low speeds. 4. Refrigerant level inspection: Observe the refrigerant in the inspection window for excessive bubbles; check the high and low-pressure pipelines and connections for leaks—repair or replace if necessary.

Where is the car thermometer sensor located?

Automotive temperature sensors are installed at the air intake grille of the front bumper. This sensor is a component of the automatic air conditioning system, primarily responsible for providing the ECU with external temperature signals. The ECU compares this signal with the interior temperature signal to determine the cabin temperature, meeting the needs of the occupants. Additional information: 1. How automotive sensors work: They convert various operational data such as light, electricity, temperature, pressure, and time into electrical signals, which are then input into the vehicle's computer system. The computer uses pre-stored programs to perform calculations and analysis, thereby determining the vehicle's operating status. 2. Types of automotive sensors: Based on their structural design and the principle of air intake measurement, they can be categorized into four types: vane-type air flow sensors (MAF), Karman vortex air flow sensors (MAF), hot-wire air flow sensors (MAF), and hot-film air flow sensors (MAF). Currently, the most commonly used are the hot-wire and hot-film types.

What's the reason for no response when starting the Transit?

The reasons for no response when starting the Ford Transit are as follows: 1. Long-term parking: The usage time of the car battery is the main cause of power loss. Typically, the lifespan of a car battery is two to three years. If it exceeds this period, the car is prone to power loss after just two to three days of parking, resulting in weak starting. 2. Forgetting to turn off lights and onboard electrical devices: If you forget to turn off the interior lights when parking and turning off the engine, the battery may be depleted after a night's consumption, leading to weak starting. 3. Forgetting to turn off the air conditioning before shutting down: Not turning off the air conditioning before shutting down the engine will cause the air conditioning system to automatically start working when the ignition switch is turned on, resulting in an immediate high power load on the vehicle. Over time, this will cause damage to the battery. 4. Insufficient fuel pressure. 5. Poor performance of the fuel pump, spark plugs, or distributor.

What does MPV car refer to?

MPV stands for Multi-Purpose Vehicle, which evolved from station wagons. It combines the spacious passenger area of a station wagon, the comfort of a sedan, and the functionality of a van, typically featuring a two-box structure that can accommodate 7-8 people. Below are the detailed introductions: Classification of MPV: MPVs can be classified in various ways. Based on usage, they can be divided into family MPVs and commercial MPVs. According to seating capacity, they can be categorized into 5-seater MPVs, 7-seater MPVs like the Nissan NV200 and Dongfeng Fengxing Lingzhi, as well as multi-seater MPVs similar to the Toyota Granvia. From the development platform perspective, some MPVs are derived from sedan platforms, while others are derivatives of light buses. MPV models: MPVs feature a complete and spacious passenger area, offering great flexibility in interior design, which is one of their most attractive features. The cabin can be configured with seating for 7-8 people, along with a certain amount of luggage space. The seats are flexibly arranged and can be fully folded or laid flat, with some models even allowing seats to move forward, backward, sideways, or rotate. When the third-row seats are folded down, it resembles a large-capacity station wagon. Folding down the three right-side seats creates an extra-long cargo space. Rotating the second-row seats 180 degrees backward allows passengers to face the third row for conversation, or folding the seatbacks forward turns them into a desktop for work or entertainment.

What is a white rectangular marking box parking space?

White rectangular marking boxes indicate parallel parking spaces. Below are specific details about parking space size standards: 1. Dimensions: Standard parking space sizes are mainly divided into large and small types. Large parking spaces measure 15.6 meters in length and 3.25 meters in width, suitable for medium and large vehicles. Small parking spaces measure 6 meters in length and 2.5 meters in width, suitable for compact vehicles. 2. Arrangement: Parking space layouts can be classified as parallel, angled (30°, 45°, or 60° inclination), or perpendicular. Large vehicle spaces should not use angled or perpendicular arrangements. Standard parallel spaces measure 6 meters long and 2.5 meters wide. Angled spaces have a diagonal length of 6 meters and width of 2.8 meters, with 2.5 meters maintained as the vertical distance between two angled lines. Perpendicular spaces should be at least 5 meters long (typically 6 meters) and 2.5 meters wide, with 2.5x5.3 meters being the optimal standard parking space size.
