Passenger cars are after now then they have ever been, although the crash worthiness of individual models varies. Crash test reflects how the vehicle would handle in a collision with another of the same model, not versus a larger or smaller vehicle. IN some tests, neither the angle nor the obstacle corresponds with the majority of actual, real collisions.
The National Highway Traffic Safety Administration crashes cars head-on into a solid immovable barrier. It’s important to evaluate crash-test reports and not just to see if the car offers side airbags. Side bags have meant, in some cars, the difference between getting a high or a low score. Side-impact tests use properly positioned, belted test dummies, which doesn’t tell us what would happen if an occupant were out of position.
Because weight fluctuates between different versions of the same model, it’s conceivable that two-wheel- and four-wheel-drive versions of the same model could earn different scores. The extra weight of hybrid hardware has earned the hybrid version of Ford’s Escape a Poor roof-strength rating. Results for new or recently re engineered models are likely to appear months after the car goes on sale to the public because both agencies purchase their test subjects from dealerships.

A restraint which is secured to the seat of an automobile equipped with safety harnesses to hold an infant in the event of a crash is known as a child safety seat. Legally required in many countries,  baby car seats are to safely transport children up to the age of 2 or more years in cars and other vehicles.
Depending on their weight and age, countries with passenger safety rules involve laws regarding child safety in a way that the child must be confined. But these regulations are usually minimums. Car seats should always be placed in a rear seat if possible, or in front if it is sturdy enough. Car seats have been found to cause severe and fatal injuries to the child when located on a the front seat with airbags.
There are several types of car seat depending on the positioning of the child and the size of the car seat.   Infant carriers: Infant carrier’ means a restraint system required to accommodate the child in a rearward-facing position. For young infants, the seat used is an infant carrier with general weight approval of 5-20 lb. Convertible seats:  Convertible seats can be used during many stages of infancy. Many convertible seats will transform from a rear facing seat, to a forward facing seat.
