Always wear your seat belt and make sure all passengers are also wearing seat belts or using appropriate restraints.
Not wearing seat belts is extremely dangerous. In the event of a traffic accident, the driver and passengers who are not wearing seat belts may hit each other or the bodywork, or fall out of the car. In this case, they may be seriously injured or even killed. All other things being equal, passengers who are wearing seat belts are much safer.
It is prohibited to operate a vehicle with faulty seat belts.
It is dangerous to use faulty belts. In a vehicle collision, the webbing of the belt being used may be damaged. Such a belt cannot provide effective protection in the event of a vehicle collision. In a traffic accident, the front airbags and the pyrotechnic pretensioners of the seat belts are triggered simultaneously. Regardless of whether there was a passenger in the front seat or not, whether any airbags or pretensioners of the seat belts were triggered or not, it is necessary to check the serviceability of the belts installed on the front seats and all airbags. Replace faulty airbags and seat belts. It is forbidden to use a twisted seat belt: it is dangerous. In a vehicle collision, the inertial load from the weight of the body will not be supported by the entire width of the belt, but only by part of it. This increases the load on the bones of the chest located under the belt webbing, which can lead to serious injury or death.
It is prohibited to use one seat belt to fasten two (or more) people at the same time.
It is dangerous to use the same seat belt to fasten two or more passengers at the same time.
In this case, the seat belt will not ensure the proper distribution of the dynamic load from the impact of the car, and passengers wearing the same seat belt will cause serious injuries to each other or may die. Always follow the rule: each passenger has their own seat belt.
