Generally, the minimum width is 4 meters, so the minimum radius is basically 9m. The turning radius of a fire lane is calculated based on fire trucks. The turning radius of an ordinary fire truck is 9m, that of an aerial ladder truck is 12m, and some special vehicles have a turning radius of 16-20m. Below is supplementary information on the minimum turning radius: 1. The minimum turning radius refers to the radius of the trajectory circle rolled by the center of the outer steering wheel on the supporting plane when the steering wheel is turned to its limit position and the vehicle turns at the lowest stable speed. 2. To a large extent, it characterizes the vehicle's ability to pass through narrow, curved areas or bypass insurmountable obstacles. 3. The smaller the turning radius, the better the vehicle's maneuverability.

Can Tires Be Sold as Scrap?

Tires can be sold as scrap. Since tires are composed of rubber, steel, carbon black, and a variety of chemical substances, the rubber and steel have recycling value and also meet the criteria for recyclable materials. Tires are round, elastic rubber products mounted on various vehicles or machinery to roll on the ground. Generally, the lifespan of a normally used tire is 4 to 5 years. Below is an introduction to the uses of discarded tires: 1. Tire retreading: Tires in relatively good condition can be retreaded and repurposed as spare tires. 2. Plastic products: Discarded tires can be broken down into fine rubber powder, which is then used in plastic products and construction materials. For example, common synthetic running tracks often incorporate recycled tires. 3. Oil refining: Used tires can also be processed into oil. Through a series of high-temperature dissolution and cooling processes, along with advanced distillation technology, gasoline can be extracted from discarded tires.

What Causes the Unusual Noise at the Moment of Successful Ignition?

Here are the main reasons for an unusual noise at the moment of successful ignition in a car: 1. Incorrect gear shifting and clutch operation: The gear is engaged, and the clutch is not fully depressed. 2. Starter motor slipping: The car's starter motor slips at the moment of ignition. 3. Prolonged ignition time: Extended ignition time causes the flywheel to hit the starter gear upon successful ignition. 4. Belt slipping: During ignition, belt slipping may also cause vehicle noise, but this usually disappears once the engine belt speed stabilizes. Note: It is recommended to have the above issues checked at a repair shop as soon as possible to avoid affecting the vehicle's lifespan.

What are the markings for start-stop batteries?

Start-stop batteries have specific markings on their appearance, whereas regular batteries do not have dedicated symbols. Start-stop batteries are also known as maintenance-free batteries, currently dominated by AGM and EFB types. Batteries with auto start-stop functionality have a longer service life, and the two types of batteries feature different dedicated symbols. Below is relevant information about auto start-stop: 1. Introduction: The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts the engine when it's time to move forward again. 2. Operation: When the car stops due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral, causing the engine to stop automatically. To restart, the driver simply needs to press the clutch or accelerator pedal to directly start the engine.

How Often Should Car Crystal Coating Be Applied?

Crystal coating in northern regions with less rainfall can be applied approximately once a year, while in southern regions with more rainfall, it can be done every 8-9 months. More details about crystal coating are as follows: 1. Scratch Resistance: Diamond crystal hardness reaches 6H, compared to the 2H hardness of ordinary car paint, it can prevent most minor scratches. It also has an elastic recovery function, protecting the vehicle from daily minor scratches and reducing paint scratches by more than 70% compared to ordinary coatings. When external forces exceed the elastic protection range of the crystal, it usually only leaves scratches on the crystal without damaging the paint. 2. Corrosion Resistance: The ultra-fine nano-crystal layer of diamond crystal isolates the paint from the external environment, effectively preventing oxidation and resisting corrosion from bird droppings, insect fluids, acid rain, etc.

What procedures are required to change a car from five seats to seven seats?

It is not possible to change a five-seat car into a seven-seat car. The number of passengers is determined by the vehicle's factory certificate, and once determined, it cannot be altered. Below is detailed information about the driver's license: 1. Overview: The driver's license, officially known as the motor vehicle driver's license, is a certificate required by law for individuals who operate motor vehicles. Driving a motor vehicle requires certain driving skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Generally, individuals cannot drive on the road without a license. 2. Considerations: The permission to drive a vehicle is granted through the issuance of a driver's license. This indicates that obtaining a driver's license is a formal process that must be carried out by a designated authority.

Which number to call for a flat tire on the highway?

If you experience a flat tire on the highway, you can call the national highway emergency rescue number at 12122. Pricing can be discussed over the phone, as repair personnel from other service stations are generally not permitted to change tires on the highway. Precautions for driving on the highway are as follows: 1. Pre-drive vehicle inspection: Before driving, the driver should conduct a comprehensive check of the vehicle, with particular attention to various fluids, tires, braking systems, etc. Fluids should be topped up to appropriate levels; tires should be carefully inspected, and any debris in the treads should be removed. 2. Adjust the mirrors: When the rearview mirrors are in the optimal position, they allow the driver to better observe the sides and rear of the vehicle. Note that the adjustment methods for the left and right rearview mirrors are slightly different.
