You can go straight on a variable lane when the light is green because it is an emergency lane. The primary function of a variable lane is to alleviate traffic pressure. During peak congestion periods, it helps disperse traffic flow and reduces the likelihood of severe vehicle blockages. When driving on a variable lane, vehicles must follow the directional signs and are not allowed to cross lines to change lanes or make U-turns, as these actions violate traffic laws and may be captured by traffic cameras. When passing through signal-controlled intersections, every vehicle must enter the designated lane according to the direction indicated. The same traffic rules apply to variable lanes. For example, if the straight lane signal is red while the left-turn signal is green, but a vehicle in the left-turn lane waits for the straight signal to turn green, this behavior constitutes a traffic violation.

Whether you can go straight in a variable lane when the light is green depends on the current setting of the lane. As someone who has been driving for over twenty years, I believe this is closely related to traffic signals. When the green light comes on, you must immediately check the lane markings: if there's a straight arrow or an electronic display showing 'Go Straight,' then you can definitely proceed straight; but if it changes to a left-turn-only lane during peak hours, even with the green light on, you cannot go straight, otherwise, you'll block other traffic or even cause a collision. I've experienced many intersections, like the main roads in the city, where the straight green arrow is active during the day but switches to other directions at night—very flexible. In short, never focus solely on the green light and ignore the real-time signs. Safety first. It's advisable to slow down and observe in advance while driving; once you develop the habit, you won't make mistakes. Remember, these variable lanes are designed to optimize traffic flow and reduce congestion.

Does Using 92 Octane Gasoline Affect Audi?

According to the official vehicle manual recommendation, Audi should use 95 octane gasoline, and using 92 octane may have adverse effects. In addition to checking the appropriate gasoline grade in the vehicle manual, Audi owners can also find this information on the fuel tank cap, which is usually marked there. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the required gasoline grade. High-compression engines can be tuned to use lower-octane gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane rating and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If an Audi is occasionally filled with the wrong gasoline grade, simply switching back to the correct grade after consumption is sufficient. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, accidentally using higher-octane gasoline will not cause damage, but the increased octane rating may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power output and thermal efficiency, with the practical experience being poorer performance. Conversely, using lower-octane gasoline in vehicles recommended for higher-octane fuel can cause engine knocking. Due to the significantly lower octane rating, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is generated during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it may only increase noise without obvious engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.

Should the Q5 use 95 or 92 octane gasoline?

According to the official vehicle manual recommendation, the Q5 should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, the Q5 can also refer to the fuel cap, which will also indicate the recommended grade. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade. High compression ratio engines can also be tuned to use lower octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Q5 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane value is too low, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If detonation occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance will make the engine run very unstably. If the knocking is imperceptible, it only increases noise without significant damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Does a Broken Tire Pressure Sensor Affect Driving?

If the tire pressure sensor malfunctions but the tire pressure is normal, it does not affect the vehicle's ability to continue driving. There are three common types of tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and an indirect system is used for all four wheels. Compared to a fully direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system can.

Is a fuel consumption of 13L normal for a new Levin?

The combined fuel consumption of the Levin is 4.0-5.7L/100km. Currently, there are 13 models of Levin available for sale. The E-CVT Entry Edition, E-CVT Luxury Edition, E-CVT Technology Edition, E-CVT Leading Edition, and E-CVT Premium Edition have a combined fuel consumption of 4.0L/100km. The E-CVT Sport Edition has a combined fuel consumption of 4.2L/100km. The 1.5L Leading Edition and 1.5L Entry Edition have a combined fuel consumption of 5.1L/100km. The 1.5L Luxury Edition and 1.5L Sport Edition have a combined fuel consumption of 5.2L/100km. The 185T Luxury Edition and 185T Technology Edition have a combined fuel consumption of 5.6L/100km. The 185T Sport Edition has a combined fuel consumption of 5.7L/100km. The above figures are the NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 4.8-10.0L/100km. When driving, the following 5 tips can help reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: When driving, gently press the accelerator to avoid sudden increases in engine RPM and prevent the car from shaking during operation, making the car more fuel-efficient. By anticipating road conditions and applying slow and uniform acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular maintenance or vehicle checks: Timely oil changes can reduce carbon buildup (carbon buildup can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even engine misfires). Regularly check and replace dirty air filters, clean or replace fuel injectors, spark plugs, and throttle bodies as per mileage. Close windows while driving. Driving with windows open increases wind resistance. The greater the wind resistance, the more resistance the car faces, requiring more power and thus increasing fuel consumption.

Is there a penalty for stopping less than 30 cm on a slope?

Stopping less than 30 cm after the designated point results in a 10-point deduction, but being less than 30 cm from the edge does not incur a penalty. The slope test is part of the Subject 2 driving test, specifically the "Slope Parking and Starting" section. If the car's front bumper does not stop on the marker line during slope parking and exceeds 50 cm in either direction, a 100-point deduction is applied. Tips for the Subject 2 driving test: Maintain steady speed by controlling the clutch properly. When turning the steering wheel one full rotation, slightly release the clutch to prevent the car from stalling. Avoid stopping during the test, and ensure the brake is fully depressed when stopping. Failing to do either may affect your score. To prevent rolling back when starting on a slope, release the clutch to the critical point before releasing the brake. Slowly lift the clutch until you feel the car vibrate, then release the brake. Penalty standards for stopping less than 30 cm on a slope: If the car's front bumper or motorcycle's front axle does not stop on the marker line and exceeds 50 cm in either direction, it results in failure. If the deviation is within 50 cm, a 10-point deduction is applied. If the car body is more than 30 cm from the road edge line, a 10-point deduction is given. Exceeding 50 cm from the edge results in failure. If the car rolls back 30 cm but not more than 50 cm after starting, a 20-point deduction is applied.
