After driving a motor vehicle from the ramp into the acceleration lane, turn on the left turn signal and increase the speed to above 60 km/h as soon as possible to avoid affecting vehicles traveling on the main lane when merging into traffic. Carefully observe the traffic conditions on the driving lane and choose the right moment to enter the driving lane. Do not perform emergency braking or stop in the acceleration lane. Below are some precautions for highway driving: Speed control: On highways, the speed is generally between 80~100 km/h, with 90 km/h recommended as a constant speed. When exiting the highway and entering the ramp, apply the brakes twice—first when seeing the 500-meter exit sign, reducing speed to 60~70 km/h, and second when entering the ramp, reducing speed to 40 km/h. Driving and lane changing: Generally, lane changes and merging are not required.

After driving on the highway for a long time, I've concluded that the speed in the acceleration lane should be increased to match the main road as quickly as possible, typically around 80 to 100 kilometers per hour. Why? Because vehicles on the main road are moving fast, and if you're too slow, the car behind might not have enough time to avoid a rear-end collision, which can be really dangerous. I usually check the rearview mirror before entering the acceleration lane to observe the traffic flow and choose the right moment to accelerate smoothly. During smooth traffic or on roads with higher speed limits, aiming for 120 kilometers is reasonable, but don't exceed the legal speed limit. The key is to keep the process steady—avoid stomping on the gas pedal and causing the car to jerk, ensuring both yourself and other drivers can merge safely. In bad weather conditions like heavy rain or fog, you can slow down a bit, but still need to speed up to match the flow of the main road.

What is the mileage for the first vehicle maintenance?

New car first maintenance is at 3 months or 5000 kilometers, whichever comes first. Before the first maintenance, pay attention to the following points: 1. Make an appointment in advance: It is best to make an appointment with the 4S store in advance, otherwise, without an appointment, you may encounter situations where there are no available service bays or long waiting times. 2. Bring necessary documents: When going for the first maintenance, bring essential items such as the maintenance manual, vehicle registration, etc. If you are unsure about which documents to bring, be sure to ask clearly when making the appointment. 3. Record problems promptly: If you encounter any faults or questions while driving, you can record them and inform the staff during the first maintenance registration. This will help the technician to check all the issues during the first maintenance.

Is It Serious If a Sedan's Chassis Gets Scraped?

The exhaust pipe is located inside the chassis, so obstacles like speed bumps won't touch it. The chassis surface has a layer of protective coating, and minor scrapes generally don't cause significant harm. Here is additional information: 1. Inspection Method: If your car's chassis is scraped by an unknown object and you can't determine whether it affects driving safety, or if you're still concerned, it's recommended to take the car to a 4S shop or repair shop for inspection. Most repair shops have chassis lifts; once the vehicle is raised, any scrapes or damage on the chassis surface will be immediately visible. If only the steel plate is scraped, applying some paint will suffice. However, if the pipes are damaged, a thorough inspection and repair are necessary. 2. Precautions: When driving over road hazards like potholes, depressions, or grooves that could scrape the chassis, slow down and avoid them if possible—forcing through won't help. Additionally, drivers should be cautious of curbs and speed bumps.

What is the difference between cold start and hot start in cars?

Car cold start and hot start differences are as follows: Cold start refers to starting the engine when the coolant temperature is low; Hot start means starting the engine when the coolant temperature is high, with the only difference being the temperature of the coolant. Compared to hot start, cold start has the following two disadvantages: 1. Cold start is more harmful to the car: More than 80% of engine wear occurs during the cold start phase. 2. Cold start requires more time to start the vehicle: 1) During cold start, the internal temperature of the engine is too low, making it difficult for the air-fuel mixture to vaporize and combust. 2) During cold start, the engine oil temperature is insufficient, requiring time to increase the oil temperature. 3) During cold start, the gaps between internal engine components are larger, necessitating a warm-up period for thermal expansion to gradually reach the specified clearances, as excessive gaps prevent the oil film from adequately covering and lubricating the parts.

Are There Purchase Taxes for New Energy Vehicles?

New energy vehicles are exempt from purchase taxes. Currently, new energy vehicles are categorized into hybrid and pure electric vehicles, with hybrids further divided into plug-in hybrids and non-plug-in hybrids. Hybrid models, unless they are plug-in hybrids, are still subject to purchase taxes. Pure electric and plug-in hybrid vehicles do not require payment of purchase taxes. Starting from January 1, 2018, new energy vehicles listed in the "Catalog" must meet the following conditions: 1. Authorization: Pure electric vehicles, plug-in (including range-extended) hybrid vehicles, and fuel cell vehicles sold in China must be authorized. 2. Compliance: They must meet the technical requirements for new energy vehicle products. 3. Inspection: They must pass special inspections for new energy vehicles and meet the specific inspection standards for new energy vehicle products. 4.

How to Install License Plate Recognition?

Installation method for license plate recognition barrier system: 1. First, determine the installation position of the license plate recognition all-in-one machine: This will directly affect the recognition effect. The position should be decided based on the on-site environment and conditions of each entrance and exit. Generally, one camera is installed per lane. If the vehicle's direction when entering the lane is not fixed, a large angle may affect recognition, so consider installing a secondary camera to ensure recognition regardless of the vehicle's orientation. 2. Next, if using snapshot recognition, determine the installation positions of the camera and loop: The optimal distance between the camera and the loop on the incoming vehicle side is 4-4.5m. The loop position should ensure that when the vehicle triggers the vehicle detector, the front of the vehicle is tilted toward the camera side as much as possible, allowing the camera to capture clear and complete images. For a single lane (where the entrance and exit are the same lane), a dual-channel vehicle detector is required. 3. Then, determine the positions of the barrier and anti-collision loop: The barrier is usually installed on the same side as the camera, behind the camera (30cm from the camera pole to ensure the barrier gate can open conveniently). The anti-collision loop is centered directly under the barrier arm, ensuring that no part of the vehicle is under the barrier arm when the front triggers the loop or the rear leaves the loop.

What Causes the Burning Smell When Accelerating Uphill?

When experiencing a burning smell while accelerating uphill, it could be due to the smell of a slipping clutch disc burning or issues with the tires. The specific explanations are as follows: 1. It is very likely the smell of a slipping clutch disc burning: Clutch disc slippage commonly occurs in manual transmission vehicles. Since manual transmissions rely on the friction of the clutch disc to transmit power, when the clutch disc is excessively worn, the friction weakens. Consequently, when the engine's power output is too high, the clutch disc may overcome the friction and start spinning freely, causing it to overheat and produce a burning smell. If this happens, it is advisable to visit a repair shop as soon as possible to avoid more significant issues. 2. It could be an issue with the tires: During uphill driving, the front wheels may lose traction, and heavy acceleration can easily cause the tires to slip and spin freely. When the tires spin freely, a burning smell is inevitable. If this occurs, there is no need to panic; simply ease off the accelerator. If the vehicle frequently drives on uphill roads, it is best to replace the drive wheels with tires that offer better traction.
