What is the recommended driving speed in fog with 50 meters visibility?

1 Answers

When visibility is 50 meters in foggy conditions, the recommended driving speed is 30 km/h. Here are precautions for driving in fog: 1. Proper use of lights: Do not use high beams in fog as they shine upward, causing light to scatter diffusely through the fog and creating a blinding white haze ahead. 2. Maintain low speed: Strictly adhere to speed limits set by traffic regulations when driving in fog - never speed. The thicker the fog, the shorter the visibility distance, and the lower your speed must be. When visibility is less than 200 meters but more than 100 meters, speed should not exceed 60 km/h; when visibility is less than 100 meters but more than 50 meters, speed should not exceed 40 km/h; when visibility is below 30 meters, speed should be controlled under 20 km/h; if visibility drops below 10 meters, it's recommended to pull over and stop driving.

What is generally transported in Class F refrigerated trucks?

Class F refrigerated trucks generally transport frozen meat products, ice cream, dumplings, and other types of frozen food. Class F refrigerated trucks represent that the average temperature inside the compartment is below or equal to -20 degrees Celsius. To ensure the transportation of frozen, refrigerated, insulated, and constant-temperature items, the transportation department divides refrigerated trucks into eight categories, including perishable food refrigerated trucks (Classes A to F) and biological product refrigerated trucks (Classes G and H). The eight categories of refrigerated trucks are as follows: 1. Class A refrigerated trucks: average temperature between 12 to 0 degrees Celsius; 2. Class B refrigerated trucks: average temperature between 12 to -10 degrees Celsius; 3. Class C refrigerated trucks: average temperature between 12 to -20 degrees Celsius; 4. Class D refrigerated trucks: average temperature below or equal to 0 degrees Celsius; 5. Class E refrigerated trucks: average temperature below or equal to -10 degrees Celsius; 6. Class F refrigerated trucks: average temperature below or equal to -20 degrees Celsius; 7. Class G refrigerated trucks: average temperature between 8 to 2 degrees Celsius; 8. Class H refrigerated trucks: average temperature below or equal to -20 degrees Celsius.

How Many Chances Are There to Take the Driving Test for Subject 3?

There are 5 chances to take the driving test for Subject 3. Notes for Subject 3 Test: 1. If the fingerprint verification of the examinee fails, please get off the car to re-collect the fingerprint before queuing again for the test. 2. When walking around the car to observe the vehicle appearance and surrounding environment, please keep a distance of within 1 meter between the person and the car body to ensure the accuracy of radar signal detection. 3. If there are multiple people preparing for the test at the same time, after one examinee finishes the test, the next examinee needs to follow the standard process, starting from getting off the car, preparing to get on the car, walking around the car, and simulating night lights, etc., to begin the test.

Why is the Daymay X5's exhaust pipe dripping water?

Daymay X5's exhaust pipe drips water because gasoline generates water vapor and carbon dioxide after complete combustion. Water vapor is colorless and transparent at high temperatures, but when the temperature drops below 100 degrees, the water vapor condenses into water. The condensed water vapor accumulates and forms water droplets. Below is an introduction to engine water dripping: 1. Car owners should regularly check whether the car's exhaust pipe has corroded or rusted due to water accumulation. 2. If the cooling water tank in the engine leaks and cooling water enters the combustion chamber, it can also cause the exhaust pipe to drip water. 3. Excessive water accumulation can damage internal parts of the car, leading to inaccurate fuel supply, affecting performance, and even corroding the pipes.

Why does an automatic transmission car shake when starting?

The most common cause of car shaking is a dirty throttle body or excessive carbon deposits on the fuel injectors. If an automatic transmission car shakes when starting but runs normally afterward, it may be due to the following reasons: 1. The throttle body is too dirty, causing uneven air intake and resulting in shaking. 2. Poor fuel flow, leading to insufficient fuel supply at low throttle and uneven operation of engine cylinders, causing shaking. 3. Abnormal transmission operation. 4. Broken or burned high-voltage wires or spark plug failure in one cylinder, causing unstable engine operation and shaking. 5. Check if the battery voltage is within the specified range.

What is the function of an oil filter?

An oil filter is primarily used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil, thereby protecting the engine. There are mainly two types: The first type: Full-flow filter. It is connected in series between the oil pump and the main oil passage, filtering all the lubricating oil entering the main oil passage. The second type: Bypass filter, which is connected in parallel with the main oil passage and only filters a portion of the lubricating oil pumped by the oil pump. The oil filter removes harmful impurities from the oil in the oil pan, supplying clean oil to moving parts such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning effects, thereby extending the lifespan of these components. Simply put, the function of an oil filter is to filter the engine oil, making the oil entering the engine cleaner and preventing impurities from entering and damaging the precision parts of the engine.

What is an Auto-Dimming Rearview Mirror?

An auto-dimming rearview mirror refers to the interior rearview mirror's ability to automatically reduce glare, primarily preventing strong headlights from vehicles behind from reflecting off the mirror and distracting the driver, commonly known as "dazzling." The working principle of an auto-dimming rearview mirror is as follows: 1. An auto-dimming rearview mirror consists of a special mirror, two photodiodes, and an electronic controller. 2. The two photodiodes are positioned on the front and back of the rearview mirror, respectively receiving light from the front and rear of the vehicle. When headlights from a following vehicle shine onto the interior rearview mirror, the light from behind becomes stronger than the light from the front. This contrast is detected by the two photodiodes, which send an electrical signal to the mirror's conductive layer via the electronic controller. This causes the mirror's electrochromic layer to darken, ensuring that even strong light reflected onto the interior rearview mirror does not reach the driver's eyes, eliminating glare. 3. Research has found that glare can increase a driver's reaction time by 1.4 seconds. When driving at 100 km/h, this can nearly double the braking distance, posing a significant danger. The auto-dimming rearview mirror effectively addresses the issue of glare for drivers, ensuring driving safety.
