Always wear your seat belt and ensure that all passengers are also wearing seat belts or using appropriate restraints.
Not wearing seat belts is extremely dangerous. In the event of an accident, the driver and passengers who are not wearing seat belts could hit each other or the body parts, or be thrown out of the vehicle. In doing so, they can be seriously injured or even killed. Other things being equal, seat-belted passengers will be much safer.
It is forbidden to operate the car with defective seat belts.
It is dangerous to use defective seat belts. In a collision with a vehicle, the strap of the seat belt being used may be damaged. A damaged seat belt cannot provide effective protection in the event of a vehicle collision. In the event of an accident, the frontal airbags and the pyrotechnic pretensioners are deployed simultaneously. Whether or not there is a passenger in the front seat, and whether or not any airbags or pretensioners have deployed, the front seat belts and all airbags must be checked for proper operation. If necessary, replace defective airbags and seat belts. Do not use a twisted seat belt.
Twisting the strap is dangerous. In the event of a car collision, the inertial load from the body mass will not be perceived by the entire width of the strap, but only by part of it. This increases the load on the chest bones located under the strap, which can lead to serious injury or death.
Do not fasten two seat belts with the same seat belt (or more) person at the same time.
Always follow the rule: for each passenger - his own seat belt.
It is dangerous to use the same seat belt for two or more passengers at the same time.
In this case, the seat belt will not properly distribute the dynamic load from the impact of the car, and passengers wearing the same seat belt will cause serious injury or death to each other.
