What to Do When Feeling Drowsy While Driving?

Solutions for drowsiness while driving include: 1. Open the windows for ventilation. Drowsiness is often caused by poor air circulation and lack of oxygen in the car. Opening the windows to breathe fresh air can help refresh the mind. 2. Chew gum. Chewing gum keeps the mouth active. It's best to choose sugar-free gum with a cooling flavor, as sugar can raise blood sugar levels, leading to drowsiness. The cooling taste has a stimulating effect and can help prevent sleepiness. 3. Energy drinks. For long-distance driving, prepare energy drinks containing caffeine, such as coffee or Red Bull, to stay alert. However, these drinks may work for some people but not for others, as their effectiveness varies depending on individual constitution. 4. Essential balm. Essential balm has a stimulating effect. Applying it to the forehead or temples can effectively relieve fatigue. Be careful to avoid the eyes when applying, as the strong stimulation can cause tearing and affect vision.

Fill to the appropriate level on the oil dipstick. Additional information: 1. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. 2. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics, making them an essential part of the lubricant.

What is the difference between a central circle and a grid line?

The differences between a central circle and a grid line are as follows: 1. Difference: A grid line is a large yellow grid area where long-term parking is not allowed; a central circle is a small white circular or square (diamond-shaped) area in the middle of an intersection, generally assisting vehicles in turning, and controlling the vehicle's position within the central circle without crossing the line. 2. Road traffic markings: (1) Lines, solid or dashed lines marked on the road surface, curbs, or vertical surfaces; (2) Character markings, text, numbers, and various graphic symbols marked on the road surface; (3) Raised pavement markers, fixed on the road surface, serving as marking blocks, used on highways or other roads to mark centerlines, lane dividers, edge lines, and also to mark curves, entrance/exit ramps, guide lines, road narrowing, and road obstacles.

What Causes the Front Wheels to Squeak When Turning?

Abnormal noises from tires during turns commonly occur in front wheels, primarily due to the following reasons: 1. Specific causes: Excessive accumulation of foreign objects on the left and right front wheel mudguards or sound insulation pads. When the car turns, the tires interfere with these objects, producing abnormal sounds. Long-term buildup of mud and debris on mudguards causes interference with tires. The noise disappears after cleaning. Loose fastening screws on mudguards or sound insulation pads cause them to lift, leading to interference and friction with front wheels during turns, resulting in abnormal sounds. It is necessary to inspect the fastening condition of mudguards and sound insulation pads and eliminate factors such as looseness or lifting. 2. Precautions: Tire noise is a very serious issue. The source of the noise should be promptly identified and resolved as soon as possible. Otherwise, it may cause abnormal tire wear and affect driving safety.
