Nowadays, along with the development and increase of economical level, the automobile has become an essential and important transport. Also, it leads to another problem: traffic accident. Over the last century, there were more crashes in U.S than the number of the wars that Americans have been through. Therefore, people started to notice that they need the automobile safety to protect themselves. Over the last 100 years, the automobile safety has changed a lot to give out the best protection that we’re using today. Below are 3 major features: safety glass, air bag and seat belt.
Today safety glass, which will not splinter when exposed to shock, is in windshields for cars. Essential as it is, safety glass was the result of a clumsy mistake. In 1903, Edouard Benedictus, a French scientist inadvertently knocked a glass flask to the floor when fetching reagents. He heard the glass shatter, but later, he saw the broken pieces of the flask still hung together, more or less in their original contour. Then he learned that the flask had recently held a solution of cellulose nitrate, a liquid plastic, which had evaporated, apparently depositing a thin coating of plastic on the flask’s interior. He experimented with coating glass with liquid plastic, then shattering it and it was not broken. When Benedictus read that most of the drivers seriously injured had been cut by shattered glass windshields, he knew that his unique glass could save lives. Unfortunately, automakers were uninterested in the costly safety glass for windshields. It was not until the outbreak of World War I that safety glass found its first application: as the lenses for gas masks. After automobile executives examined the proven performance of the new glass under the extreme conditions of battle, safety glass’s major application became car windshields. It was very dangerous when something hit your car, the glass was broken and as a result, you would be sore and even dead. But with this unbreakable glass, now you don’t have to worry about this because nothing can touch you from the outside.
An air bag is a high-speed inflation device hidden in the hub of the steering wheel or in the dash on the passenger’s side. Today they are installed on all new passenger cars sold in the United States. Some automobiles have side-impact air bags, located in doors or seats. The inflated bag creates a cushion between the occupant and the vehicle’s interior.
There are three safety features in the egg project. The three safety features are seat belts, brakes, and airbags. The seat belts are made out of tape. The seat belts put pressure on the passenger. This means that it will keep the passenger inside the car instead of flying out and getting injured. The airbags are made out of bubble wrap. The bubble wrap will have a huge impact on the area of the passenger. It is like a soft cushion. This protects the passenger from hitting the passenger. The passenger will get hurt by the airbag, but not as much without one. If there wasn’t an airbag in a car, people would be getting into a second collision. A second collision is where the body hits the car. That is the whole point of an airbag. The brakes are made out of cotton balls. The brakes prevent the passenger from getting hit and it puts force on it. Also, they prevent it from getting into a first collision. A first collision is where a

Vehicles are a main necessities of our life, it have been with us for quite a long period; it is time efficient, but the number of death it have caused is not easily avoided; therefore the engineers have designed vehicle safety features such as seat belts and crumple zones regarding the concepts of Newton’s Laws of Motion to help save our lives.
In 1966, the National Highway Safety Bureau (NHSB) was designed by the Highway Act. NHSB’s director, Dr. William Haddon, noticed that he could prevent motor-vehicle injuries by applying public health methods and epidemiology. Various passages demanded the government to set standards for the highway and motor vehicles. The federal government responded by developing new safety features in cars such as safety belts, head rests, and shatter-resistant windshields. Barriers, reflectors, and center line strips were placed on roadways to provide direction and illumination. Traffic safety laws, wearing a safety belt, and public education encouraged drivers to make safer decisions. The use of safety belts has skyrocketed from 11% in 1981 to 68% in 1997 and decreases When the community and government understood the necessity for motor-vehicle safety, various programs such as Prior to the implementation, the rate stood at 18 per 100 million vehicle miles traveled in 1925; however, the rate stood at 1.7 per 100 million vehicle miles traveled in 1997. With all of the new safety features with cars, public education and enforcement of safety laws, “motor-vehicle crashes remain the leading cause of injury-related deaths in the United States.” Over 23.9 million vehicle crashes were reported in 1997; estimated costs were around $200 billion.

Does everyone have their seat belts on? This is a question that children hear repeated each time their parents start the vehicle. Seat belt laws are enforced in in forty-nine of the fifty states even so; parents reiterate it time after time to keep us safe rather than just following the law. Beginning in the 1930’s, physicians determined that a lap belt should be used in automobiles to avoid serious injury or a fatality. Over the years, the simple two-point lap belt has evolved into a multiple point seat belt used for many different types of driving. Racer car drivers generally use a five-point harness. However, for normal every day driving “the three-point”, lap and shoulder combination “is considered the safest version and is the kind found in most vehicles today” (“Seat Belts”, 2010). Seat belts are the primary prevention of ejected passengers. Opponents argue that wearing seatbelts should be a personal choice, not something enforced by a law. Proponents support the initial theory; it is safer to remain within the confines of the vehicle for increased protection. It is imperative that seat belts laws are enforced to increase seat belt use, decrease motor vehicle injuries and fatalities, in addition, reduce costs in medical expenses and insurance claims from automobile accidents.
The seat belt or safety belt is a safety harness designed to secure the occupant of a vehicle against harmful movement that may result from a collision or a sudden stop. As part of an overall automobile passive safety system, seat belts are intended to reduce injuries by stopping the wearer from hitting the hard interior of the vehicle, or other passengers, when in the correct position for the airbag to deploy it prevents the driver and passengers from being thrown from the vehicle. Seat belts absorb the energy of the impact by being designed to stretch during any sudden deceleration, so that there is less speed differential between the passenger's body and their vehicle interior, and also to spread the loading of impact on the passenger’s
There are three reasons why we should use seat belt when driving which are preventing death when an accident occurs, cultivate themselves too not violate the law and protecting our passengers.
ABS (Anti-lock Braking System) is a system which stops the wheels locking up into a skid when braking on slippery surfaces. It works by using a computer which monitors wheel speeds and drives pistons which alternatively increases and decrease brake pressure several time a second on individual wheels when it senses they are about to lock up.
Cars are large objects of great mass which can reach very fast velocities, this can be a dangerous combination if the physics aren’t correct. Seeing as there is over 1.2 billion cars world wide, physicians have put much detail into aspects of cars to make them as safe as possible. In the paragraphs below I will be be briefly discussing different aspects of the everyday automobile and its safety.
Longtime mechanic Carlos Contreras says, "a million things can go wrong when working on a car." And a lot of them hurt like heck (Woolston, Chris. Car Mechanics. Healthday, n.d. Web.). Whether you’re in car restoration or own an auto shop, safety in the workshop is always the most important. Keeping yourself, your friends, your family, your customers and any other people safe amongst the dangers of motor vehicle repair is something you should always consider. Injuries occur on a daily basis in the workshop. Safety is the number one issue everyone should be concerned with, mechanic or not. One of the OSHA standards is regularly violated by shops and mechanics is the right to know the standard. This policy is depicts the use of potentially hazardous chemicals which is a very common occurrence in the automotive business. It simply requires that employees be notified of the possible dangers of any of the chemicals they are using. OSHA also insists that employees have a right to know how they might be affected by chemicals in the shop (Ray, Linda. Work. Chron, n.d. Web.). The right to know standard requires labeling all chemicals, and including lists with information, training for employees in use of the chemicals and a plan that outlines how the auto shop plans to follow the right procedures. Another subject would be the general protection of workers. Many auto shops also violate another OSHA regulation by not providing adequate safety equipment for the workers. Auto shops are required to have plans and safety equipment that can be dealt by the hazards that many employees are exposed to at work shop (Ray, Linda. Work. Chron, n.d. Web.). For example,...
Car accidents are the leading cause of death for people under the age of 35. Wearing a seat belt can prevent death in about half of these accidents. Did you know that every 15 seconds someone is injured in an automobile accident if they are not buckled up, or that every 13 minutes someone is killed in a crash. Failure to wear a seat belt contributes to more fatalities than any other single traffic safety related behavior. According to the National Highway Traffic and Safety Administration seatbelts saved nearly 12,000 lives in the United States in the year 2000. The NHTSA estimates that more than 9,000 U.S. car accident fatalities in 2000 would have been avoided if the victims had been wearing seatbelts. Sixty three percent of the people killed in accidents were not wearing seat belts. The NHTSA a...

Richard Petty once said “You’ll got home safe, so drive safe, and stay safe.” Being a racing legend, he is an advocate for safe driving to minimise the cases of road crushes that have been on the rise. He double up as the chairman of the Veterans’ Safe Driving Initiative, the initiative is aimed at guiding the veterans returning from deployment on safe driving tips. It is necessarily important since the infrastructure has changed over time. Another initiative is being run in Minnesota where the teens are guided on the important safe driving tips. Study shows that more crushes are likely to occur in teen driving than veteran driving. It is also evident that young drivers are more likely to cause a crush within six months of passing the driving test and young male are worse than the females in the field.
