Can You Make a U-Turn When Turning Left?

You can make a U-turn when turning left. Rules for U-turns at traffic lights: At intersections with U-turn traffic lights or road signs indicating U-turns, you can make a U-turn after ensuring safety. At intersections without a U-turn light but with a left-turn light, U-turns are allowed. Drivers can use the left-turn lane to make a U-turn at the central median or when approaching the intersection, provided it does not affect normal traffic flow. Yellow grid areas: Although stopping is prohibited in yellow grid areas, if the traffic light ahead is red, vehicles behind should reasonably avoid stopping in this area. A U-turn can be completed at the central median barrier. Crosswalk areas: U-turns are not allowed on crosswalks or pedestrian crossings. You can make a U-turn after crossing the crosswalk when the light is green, but never make a U-turn directly on the crosswalk.

How long is the lifespan of an electric car battery before it needs replacement?

Electric car batteries generally have a lifespan of around ten years. Precautions for using electric car batteries: After parking, avoid prolonged use of electrical equipment. The service life of a battery is typically about 3 years. For vehicle battery maintenance, try not to play music after turning off the engine. If the vehicle is parked for an extended period, disconnect the negative terminal of the battery to extend its lifespan. Automobile warranty legal provisions: On October 1, 2013, the national "Regulations on the Repair, Replacement, and Return of Household Automobiles" was officially implemented. Article 17 of the regulations states that the warranty period for household automobiles shall not be less than 3 years or 60,000 kilometers, whichever comes first. The three-guarantee validity period for household automobiles shall not be less than 2 years or 50,000 kilometers, whichever comes first.

What causes the green light to flash without switching to gas in a gasoline-to-gas conversion?

If the green light flashes without switching to gas in a gasoline-to-gas conversion, it might be due to a stuck fuel pump or a malfunctioning fuel pump, which can cause sudden fuel supply interruption and engine stalling. Introduction to Gasoline-to-Gas Conversion: It involves installing a natural gas system in a conventional gasoline-powered vehicle, allowing it to switch between gasoline and natural gas, effectively making it a dual-fuel vehicle. When the coolant temperature exceeds 60 degrees Celsius, the system can switch between natural gas and gasoline. When the natural gas is nearly depleted, the system can also be forced to switch back to gasoline mode. Pros and Cons of Gasoline-to-Gas Conversion: The advantages include cleaner and more efficient combustion, reduced carbon buildup, superior anti-knock performance, and no dilution of engine oil, thereby extending the lifespan of internal engine components. The drawbacks include a potential power loss of 10% to 20% in some converted vehicles, increased vehicle weight, and slightly reduced performance compared to running on gasoline.

What is the application scope of 85w-90 gear oil?

85w-90 gear oil is suitable for manual transmission vehicles. Working conditions of gear oil: The contact area between gears is very small, basically line contact, and during movement there is both rolling friction and sliding friction. Therefore, the working conditions of gear oil are quite different from other lubricants. Due to the small contact area between gears, the pressure they bear is very high. The tooth surface pressure of some heavy machinery reducer gears reaches 400-1000MPa, and the operating conditions of hypoid gears in automotive transmission systems are even more demanding with heavier loads. The pressure at the contact points can be as high as 1000-4000MPa. Under such high pressure, the lubricating oil is easily squeezed out from between the teeth, which can easily cause scratches and wear on the tooth surfaces. Therefore, gear oil must have the performance to keep the tooth surfaces in a state of boundary lubrication and elastohydrodynamic lubrication under high loads. Functions of gear oil: Lubricate the transmission system, reduce wear on gears and moving parts, ensure normal operation of the transmission system, and extend service life. Reduce friction and transmission losses in gear transmissions, improving mechanical efficiency. Cool transmission components. During gear transmission, a large amount of heat is generated due to tooth surface contact friction. If not dissipated in time, it can cause

What is the lifespan of a Mazda rotary engine?

Mazda rotary engines have a lifespan of approximately 100,000 kilometers. The rotary engine uses a triangular rotor's rotational motion to control compression and exhaust. Taking the Mazda RX8 2008 manual model as an example, its body dimensions are: length 4460 mm, width 1770 mm, height 1340 mm, wheelbase 2700 mm, fuel tank capacity 65 liters, and curb weight 1406 kg. The Mazda RX8 2008 manual model is equipped with a 1.3L naturally aspirated engine, with a maximum power of 170 kW at 8200 rpm, and a maximum torque of 211 Nm at 5500 rpm.

Can a Temporary ID Be Used for the Subject 2 Driving Test?

Temporary ID can be used for the Subject 2 driving test. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," first-time applicants for a driver's license must submit their identity proof. Although a temporary ID is valid for only three months, it still serves as the applicant's identity proof and holds the same legal validity as a permanent ID. The Subject 2 test usually requires magnetic stripe scanning, but a temporary driver's license cannot be scanned. If using a temporary ID for the Subject 2 test, you need to inform the test center staff in advance, and they will arrange the test for you. Generally, candidates using temporary IDs are scheduled to take the test last. If you lose your ID on the test day, you can apply for a temporary ID at the household registration office before the test. Subject 2: For small vehicles (C1), the test includes five mandatory items: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves). In some regions, there is a sixth item: highway toll card collection. For C2 vehicles, the test includes four mandatory items: reverse parking, parallel parking, right-angle turns, and curve driving (S-curves). For large vehicles (A1, A2, A3, B1, B2), the test includes: pole test, stopping and starting on a slope, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, passing through a width-restricted gate, passing through continuous obstacles, driving on undulating roads, narrow-road U-turns, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling.
