How to Tell if the Car Body is Straight While Driving?

Methods to determine if the car body is straight while driving: You can use the central divider line or edge line of the road as a reference. When the vehicle is moving, if the markings visible in both side mirrors appear parallel to the car body, then the car body is aligned straight. Otherwise, minor adjustments are needed. For parking situations where no other cars are nearby, check through the rearview mirror whether the rear of the car is parallel to the road edge or parking lines. If there are adjacent vehicles, observe through the rearview mirror whether the distance to the neighboring car is equal at both front and rear - equal distances indicate proper alignment. If the rear of your car is too close to the adjacent vehicle or the front is too close to it, this indicates the car body is at an angle.

What does 265/65r17 mean?

265/65r17 is the specification of a tire. 265 refers to the tire width of 265mm, 65 refers to the aspect ratio, meaning the section height is 65% of the width. R indicates that the tire is a radial tire, and 17 means the rim diameter is 17 inches. Tires with a high aspect ratio have longer sidewalls, providing better cushioning and relatively more comfort, but weaker resistance during turns. Conversely, tires with a low aspect ratio and large inner diameter have shorter sidewalls and wider treads, resulting in a larger contact area and the ability to withstand greater pressure. They are more sensitive to the road surface and offer greater lateral resistance during turns. The normal tire pressure for a car ranges between 230-250kpa. However, the specific normal tire pressure should be based on the manufacturer's recommended value, which can usually be found in the vehicle's user manual, on the label near the driver's side door (B-pillar), in the drawer next to the driver's seat, or on the fuel tank cap. Car owners should develop the habit of regularly checking tire pressure. If the tire pressure frequently exceeds 20% of the normal pressure, the tire's lifespan will decrease by 10%; if it frequently falls below 30% of the normal pressure, the tire's lifespan will be reduced by 52%.

How to Reverse a Car for Beginners?

When reversing as a beginner, pay attention to the following: 1. Before reversing, first check the situation behind the car, estimate the path of reversing, and determine whether the front of the car will hit any obstacles; 2. According to the direction the rear of the car needs to move, turn the steering wheel with both hands; 3. During the reversing process, do not keep looking behind the car. While ensuring safety behind, observe the left and right rearview mirrors from time to time. It should be noted that when reversing downhill, do not use neutral gear for reversing, as it makes speed control difficult. Especially on slippery downhill roads, stepping on the brake or clutch pedal can cause the car to skid or lose control. The correct method is to engage reverse gear, release the handbrake, and use the engine's drag effect to reverse smoothly.

What Lights Should You Use When Driving in Heavy Rain?

When driving in heavy rain, you should turn on the rear fog lights. The red tail lights themselves have excellent penetration, and ordinary heavy rain cannot block their light. Rear fog lights are very bright and are designed to penetrate thick fog. Using them in regular rainy conditions can easily dazzle the drivers behind you, which may affect their visibility and compromise your safety. Driving without lights in rainy conditions can directly impair the judgment of the car in front regarding the situation behind, making it difficult to determine the position, distance, and speed of the following vehicle. If the car in front changes lanes or turns without clear information, it could easily lead to a rear-end collision.

What happens if you forget to engage the handbrake while driving?

Forgetting to engage the handbrake while driving can lead to: 1. Constant illumination of the brake system warning light on the dashboard: If you drive without releasing the handbrake, the warning light will stay on, and some vehicle models may also display text reminders on the dashboard screen; 2. Difficulty in starting or even inability to move, as if the car is dragging something heavy behind: Engaging the handbrake creates significant resistance to the movement of the rear wheels, making it noticeably harder to start at low RPMs; 3. Smoke from the rear wheels, red-hot brake discs, and a burning smell: Friction between the brake discs and brake pads generates a large amount of heat, leading to smoke and a burning odor; 4. Increased fuel consumption and accelerated wear of the brake pads.

What is the normal water temperature when driving?

The normal water temperature while driving is around 90 degrees. The engine temperature is usually sensed by the water temperature sensor, and the normal engine temperature is linked to the water temperature. Typically, the optimal engine water temperature is around 90 degrees. The engine temperature varies under different operating conditions: in a cold state, the temperature is around 85 degrees, while in a hot state, the water temperature can exceed 100 degrees. Reasons for high water temperature in a car: 1. Insufficient coolant; 2. Radiator leakage; 3. Cooling fan malfunction; 4. Thermostat failure; 5. Water pump failure. Reasons for low water temperature: 1. Damaged thermostat preventing it from closing; 2. Cooling fan malfunction causing it to run continuously.
