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 bodywork, or fall out of the vehicle. In doing so, they can be seriously injured or even killed. Other things being equal, seat-belted passengers are much safer.
It is forbidden to operate the car with defective seat belts.
It is dangerous to use faulty belts. In a collision with a vehicle, the strap of the seat belt being used may be damaged. Such a 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. Regardless of whether there was a passenger in the front seat or not, whether or not any airbags or pretensioners were deployed, it is necessary to check the serviceability of the belts installed on the front seats and all airbags. Replace defective airbags and seat belts. It is forbidden to use a twisted seat belt: it 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.
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. Always follow the rule: for each passenger - his own seat belt.
