According to regulations from the national transportation department, the speed limits for four-lane highways are as follows: 1. First lane: 100-120 km/h (generally dedicated to passenger vehicles); 2. Second lane: 80-100 km/h; 3. Third lane: 60-100 km/h; 4. Fourth lane: emergency lane. Some highways may have additional regulations, which should be followed as indicated by road markings. On roads without speed limit signs or markings, motor vehicles must not exceed the following maximum speeds: 1. Roads without a centerline: 30 km/h for urban roads and 40 km/h for highways; 2. Roads with only one lane in the same direction: 50 km/h for urban roads and 70 km/h for highways.

What to Do If Your Driver's License Expired for One Month?

Solution for a driver's license expired for one month: You just need to renew it within one year. Otherwise, it will be revoked after one year. Here are the precautions for an expired driver's license: 1. Legal provisions: According to the Road Traffic Safety Law, if the driver's license is not renewed for more than one year after the expiration date, the motor vehicle driver's license will be automatically revoked; if it exceeds two years, the normal use of the driver's license can be restored after passing the subject one exam; if it has been revoked for more than two years, you need to reapply. 2. Invalid license: It is particularly important to note that you must not drive a motor vehicle after the driver's license has expired. Driving with an expired license is considered driving without a license or is treated as driving without a license. Driving a motor vehicle will result in a fine of not less than 200 yuan but not more than 2,000 yuan, and may also be detained for up to 15 days.

Is There a Purchase Tax on Used Cars?

Used cars do not require payment of purchase tax. However, if the purchase tax was not paid when the car was new, the new owner will need to pay the outstanding purchase tax after purchasing the used car. It is important to note that if the used car is a tax-exempt vehicle, according to relevant national regulations, a tax-exempt vehicle used for more than ten years does not require back taxes to be paid. But if the tax-exempt vehicle to be purchased has been used for less than ten years, the buyer should consider whether they are willing to pay the back taxes. More relevant information is as follows: 1. Payment of purchase tax: A car only needs to pay the purchase tax once, usually when it is purchased new. 2. Check payment records: When buying a used car, you should check whether the vehicle has a purchase tax payment record. If not, clarify with the original owner whether it was lost or if the car is tax-exempt. If the purchase tax payment record was lost, the original owner can apply for a replacement. If the car is tax-exempt, consider that national regulations state that a tax-exempt vehicle used for more than ten years does not require back taxes to be paid. However, if the tax-exempt vehicle to be purchased has been used for less than ten years, the buyer should consider whether they are willing to pay the back taxes.

Where is the tire pressure reset button for the Sagitar?

The tire pressure reset button for the Sagitar is located on the control lever on the left side of the steering wheel. Tire Pressure Reset: Tire pressure reset is the operation of resetting the tire pressure monitoring system after addressing a tire pressure fault. Tire Pressure Reset Method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. Hazards of Overinflated Tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks, blowouts, or even tire bursts.

Where is the chassis number of Refine located?

JAC Refine's chassis number is usually located at the lower left corner of the front windshield or on the hinge pillar of the driver's door. Here are some precautions when using a new JAC Refine: 1. The break-in period for Refine vehicles is generally three months or 2,500 kilometers. The break-in period usually refers to the process where mechanical components initially come into contact, rub, and mesh during operation. During the break-in period, it is best not to exceed a speed of 100 km/h, and the engine speed should not exceed 2,500 rpm to ensure proper engine break-in. 2. When driving at low speeds, the actual load on the vehicle is greater than at medium speeds. Therefore, it is not advisable to maintain a speed below 60 km/h for an extended period during the break-in period. The speed should be gradually increased. If the vehicle is consistently driven at 80 km/h during the break-in period and the speed is suddenly increased afterward, the new vehicle may not adapt well. Therefore, the maximum speed during the break-in period should be increased progressively. 3. Avoid sudden braking and rapid acceleration during the break-in period. 4. Always warm up the engine before starting and avoid overloading. Running a new vehicle at full capacity can cause damage to the components.

What is the fuel consumption of the Buick Excelle 1.3t?

The actual fuel consumption of the Buick Excelle 1.3t is around 8 liters per 100 kilometers. During actual driving, factors such as driving habits and road conditions can cause the real fuel consumption to differ from the theoretical values indicated. Ways to improve fuel economy: 1. Avoid opening windows on highways: Many people prefer driving with windows open on highways, but this allows a lot of wind to enter the car, increasing driving resistance. 2. Avoid lugging the engine: Some drivers do not shift gears at the appropriate times, leading to engine knocking. Good shifting habits can save a lot of fuel, and there is a significant difference in fuel consumption between sudden acceleration and smooth acceleration. 3. Maintain proper tire pressure: Some drivers overlook tire pressure and drive off without checking. When tire pressure is insufficient, the vehicle's frictional resistance increases, leading to higher fuel consumption. 4. Use fuel system cleaners: Cleaners can remove gum and dirt from the fuel system, saving fuel, reducing exhaust emissions, and preventing component corrosion and rust.
