What are the standard specifications for seat belt usage?

The standard specifications for seat belt usage are as follows: Regularly inspect the condition of the seat belt. When pulling the belt downward slowly by hand, it should smoothly extend from the retractor. If you pull the belt abruptly, it should not move; otherwise, the seat belt is malfunctioning. Replace it immediately if any damage is found. All bolts securing the seat belt to the floor near the seat should be tightened according to specifications, and sealant should be applied around the bolts. Before using the seat belt, pull the lap belt out as much as possible, adjust the buckle near the waist, and loop the remaining belt over the shoulder. Adjust the shoulder strap length to fit near the chest, leaving enough slack to fit a fist. The three-point lap belt should be worn as low as possible, around the hips, not the waist. The shoulder belt should not be placed under the arm but should cross the chest diagonally. Seat belts are for individual use only; sharing is strictly prohibited. Do not twist the seat belt while using it. Avoid placing the seat belt over hard or fragile objects, such as glasses, pens, or keys in clothing. Also, keep the belt away from sharp objects to prevent damage. When the seat is unoccupied, retract the seat belt into the retractor. To remove the belt, hold it with your left hand, press the buckle release with your right hand, and slowly retract it with your left hand. Do not let go immediately after unbuckling to prevent the metal buckle from snapping back and breaking glass or causing injury. Do not recline the seat back too far, as this may hinder the proper extension and retraction of the seat belt, affecting its effectiveness. Ensure the buckle is securely fastened to prevent accidental detachment under force. After any accident, the seat belt must be reset. This is because, during a severe collision, the belt stretches, and many components, including sensors, are designed for one-time use.
As a seasoned driver who has been behind the wheel for years, I've used seat belts countless times, and proper usage is crucial. Buckle up immediately after getting in the car, with the shoulder strap passing over your shoulder and resting firmly across your chest—never on your neck or under your armpit. The lap belt must sit low across your hip bones, not on your abdomen, to prevent internal injuries during sudden braking. Keep it snug throughout the ride without any slack, and listen for the crisp click when latching the buckle. Always use seat belts in all positions, including rear passengers—never skip this step. I remember one accident where I, securely buckled, escaped mostly unharmed, but my friend in the back seat, unrestrained, suffered serious injuries. Regularly checking for wear, fraying, or sticking mechanisms is also essential. Once it becomes a habit, driving feels safer and keeps you compliant with traffic laws.
