Is U-turn Allowed at Intersections?

Whether a U-turn is permitted at an intersection depends on the presence of U-turn signs. Below are specific situations where U-turns are prohibited at intersections: No U-turns on pedestrian crossings: Even if the traffic light is green, stopping your vehicle on a pedestrian crossing is not allowed. Typically, there are designated U-turn spaces before reaching the pedestrian crossing. However, if the current lane is a left-turn lane rather than a U-turn lane, making a U-turn is also prohibited. Clear signage prohibiting U-turns: If there are clear signs near the intersection prohibiting left turns or U-turns, then U-turns are not allowed. These sections often have traffic cameras monitoring violations.

Can a new car run at 120 mph?

New cars can run at 120 mph, but it is not recommended. It is advised that owners should run in their new cars for a period of time. For specific time and precautions, please refer to the vehicle's user manual. Do not exceed 3000 rpm for new cars: The engine speed of a new car should not exceed 3000 rpm, which is also the generally recommended maximum rpm during the break-in period for most cars. Run the new car on highways reasonably: If it is really necessary to drive a new car on highways, it should be done reasonably. Do not stay in one gear for a long time. Change the speed and gear every few minutes to allow the gears of each gear to be run in and reduce excessive wear on a particular gear.

What does OFF mean?

OFF is generally the button to turn off the Vehicle Stability Control (VSC) system. This system is enabled by default, and pressing and holding this button can deactivate it. Introduction to Vehicle Stability Control System: The Electronic Stability Program (ESP) is an anti-skid device that can control both drive wheels and driven wheels, incorporating ABS (Anti-lock Braking System) and ASR (Anti-Slip Regulation). The ESP system is essentially a traction control system, but unlike other traction control systems, ESP can manage both drive and driven wheels. For example, in rear-wheel-drive vehicles prone to oversteering, where the rear wheels lose control and cause the car to fishtail, ESP will brake the outer front wheel to stabilize the vehicle. In cases of understeering, to correct the tracking direction, ESP will brake the inner rear wheel, thereby adjusting the driving path. Mechanism of Vehicle Stability Control System: The role of ESP is to automatically intervene and correct the driver's actions when the vehicle is operated beyond its limits. The system uses two methods to control the vehicle's movement: first, by reducing throttle input to decrease engine power and slow down the vehicle; second, by applying brakes to specific wheels to reduce the vehicle's speed back within safe limits.

Do 6-year-old tires need to be replaced?

6-year-old tires need to be replaced. Generally, car tires should be replaced every 5 years or approximately 60,000-80,000 kilometers. If the tires show severe wear, they must be replaced earlier. If the mileage reaches 80,000 kilometers without any tire issues, replacement is necessary even if the tires haven't been in use for 5 years. Similarly, if the tires have been used for 6 years, even if the mileage hasn't reached 80,000 kilometers, visible signs of aging and cracking on the tire surface indicate the need for replacement. Car owners should pay attention to the following points when replacing tires themselves: Choose the right tires: When replacing tires, it's important to select the appropriate ones. The specifications of the new tire should match those of the other tire on the same axle, such as speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. Replace the valve stem as well: After replacing the tire, the aging cycles of the new tire and the valve stem differ. During the new tire's lifespan, the valve stem may develop issues that are not easily noticeable. Therefore, it's advisable to replace the valve stem at the same time as the tire.

What are the hazards of starting a car while it's already running?

Starting a car while it's already running can cause several hazards, as detailed below: Damage to gears: If the engine is started again while already running, the most vulnerable components are the gears, specifically the engine's flywheel and the starter motor's gears, which can suffer damage from meshing improperly. Damage to the motor's copper sleeve: The reactive force from the engine can impact the starter motor, potentially harming the copper sleeve. While occasional instances may not cause significant harm, repeated attempts can lead to engine damage. No impact: Some modern vehicles are equipped with start protection mechanisms. When the engine is already running, turning the ignition key to the start position either prevents the starter motor from engaging or makes the key immovable. Certain vehicles, however, allow the starter motor to operate even when the engine is running, thanks to optimized system designs that ensure no adverse effects occur even if the starter motor is activated.

Does Slight Deformation of the Wheel Rim Edge Affect Safety?

Slight deformation of the wheel rim edge affects safety. It can cause tire leaks, uneven bouncing, and driving vibrations, leading to safety issues. Causes of the impact: Slight deformation of the car wheel rim can prevent the tire from fitting properly with the rim, creating gaps. Unstable tire pressure can lead to dangers such as tire blowouts and bursts. Solutions for slight wheel rim deformation: If the car wheel rim is deformed, it is recommended to replace it with a new one. When choosing a replacement, ensure the wheel rim size is appropriate for a safer fit. If opting for repair, seek professional assistance and avoid making arbitrary changes yourself, as it may lead to adverse consequences.
