What are the U-turn rules?

Here are the specific rules for U-turns: 1. U-turns are allowed in yellow grid areas; 2. U-turns are allowed at intersections with U-turn signals; 3. U-turns are allowed at intersections without U-turn signals but with left-turn signals; 4. If there are no 'No U-turn' signs, U-turns are allowed. Below are the situations where U-turns are not allowed: 1. Intersections where left turns are prohibited; 2. Pedestrian crossing areas; 3. Two left-turn lanes with the middle lane not allowing U-turns; 4. Intersections with 'No U-turn' signs; 5. The leftmost lane has only a straight arrow; 6. Single solid yellow lines prohibit U-turns; 7. Road sections where U-turns are not allowed.

What vehicles can be driven after downgrading from B2 to C1M?

B2 downgraded to C1M can drive small cars, low-speed trucks, three-wheeled vehicles, and wheeled self-propelled machinery. Additional information: 1. C1 driver's license: A type of driver's license code. 2. Physical examination requirements: Motor vehicle drivers aged 70 and above (including 70) should undergo an annual physical examination, while those below 70 do not need to. 3. Types of vehicles not allowed to drive: C1 license holders cannot drive: large buses, tractors, city buses, medium-sized buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams.

What to Pay Attention to When Driving on the Highway in 40-Degree Heat

Here are the precautions for driving on the highway in 40-degree heat: 1. Avoid running the air conditioning for extended periods: When the engine idles, incomplete combustion of gasoline produces carbon monoxide. Vehicles equipped with air conditioning usually have good sealing. Most people will experience dizziness, fatigue, and reduced memory after staying in such an environment for several hours. Additionally, passengers exhale large amounts of carbon dioxide, drastically reducing oxygen levels inside the car. Therefore, adjust the air conditioning settings appropriately or open the windows periodically for ventilation. 2. Avoid overinflating tires to prevent blowouts: In summer, highway surface temperatures are extremely high, and continuous friction with the road further increases tire temperatures, making blowouts and subsequent accidents more likely. In summer, it's best to maintain tire pressure around 2.3 kPa and avoid overinflation. 3. Refill the radiator promptly if low on water: If large amounts of white smoke suddenly emerge from the front of the car while driving, pull over immediately. This is a classic symptom of low radiator water levels. 4. Prevent vehicle fires in high temperatures: Vehicle fires are mainly caused by electrical or fuel leaks. Poor maintenance, aging parts, and damaged wiring can lead to electrical leaks. A corroded fuel tank over time can also cause fuel leaks, so preventing fires in high temperatures starts with proper vehicle maintenance. 5. Inspect tires frequently and replace them when necessary: Summer demands thorough vehicle maintenance and inspections, especially when driving on the highway in extreme heat, as it puts extra strain on tires and the engine. Always perform a thorough check before hitting the road.

What are the phenomena and causes of piston slap in motorcycles?

Piston slap in motorcycles refers to a crisp, sharp "clank, clank" or "click, click" sound produced in the cylinder when the engine starts or idles, caused by the piston swinging inside the cylinder and its head or skirt colliding with the cylinder wall. It resembles a hammer striking the cylinder, hence the term piston slap. Piston slap is not a piston damage fault but rather a noise nuisance. Below are the reasons for the occurrence of piston slap in motorcycles: Around the top dead center of the compression stroke, due to the tilt of the piston and the change in the direction of lateral pressure, the contact surface of the piston with the cylinder wall shifts from the rear thrust face to the main thrust face, resulting in a lateral swing. This leads to the periodic knocking sound of the piston striking the cylinder, known as piston slap.

What Causes Black Smoke from Motorcycle Exhaust Pipe?

Black smoke from the exhaust pipe indicates that the exhaust gas contains excessive carbon particles, which is caused by incomplete combustion during engine operation. Here are the relevant explanations: Abnormal exhaust smoke: Includes black smoke, white smoke, and blue smoke. Black smoke indicates a rich air-fuel mixture, related to defects in the fuel supply, air distribution, mechanical, or electronic control systems; white smoke indicates high water content in the fuel; Blue smoke indicates oil burning. Poor acceleration or weak power: Manifests as difficulty starting, poor acceleration, and difficulty overtaking. Oil leakage: Oil stains appear on the engine surface or its bottom. After wiping off, they reappear in the same location the next day. Water leakage: After the car is parked for a while, water stains are always found in the same spot on the ground.

What is the wading depth of a scooter?

The wading depth of a scooter is generally below the height of the exhaust pipe outlet. Immersion at this height is completely safe. Since water does not enter the engine and does not even exceed the chassis height, you can generally start and drive the engine with confidence. Special reminders when wading: If slipping or spinning occurs while wading, stop and turn off the engine immediately. If the scooter starts to sway side to side and does not move forward, do not let the engine stall in the water. Solution for a flooded battery: It is recommended to visit a professional repair station to measure the specific gravity of the battery electrolyte using a battery hydrometer. If the specific gravity is too low, you can drain the existing electrolyte, prepare a new mixture with the appropriate concentration as required, refill it, and then recharge the battery using a battery charger.
