Collisions Breaking distance To avoid collisions you need to understand stopping distance. • Thinking distance - the time taken to react by a driver. During reaction time the car continues moving. • Thinking distance - distance travelled before the driver realises to brake. • Braking distance - distance taken to stop. Stopping distance = thinking distance + braking distance Factors that increase stopping distance Thinking distance: • speeding • tiredness • alcohol and drugs Alcohol is a depressant because it slows down the central nervous system. This causes a decrease in motor coordination, reaction time and intellectual performance. If high amounts are consumed the respiratory system slows down drastically also which can lead to death. …show more content…
• distractions Braking distance: • speeding • wet and icy roads • bald tyres and poor brakes How speed affects stopping distance These diagrams represent how thinking distance and braking distance depend on the speed of the car.
The stopping distance is increased the faster the speed. Effectiveness of seat belts Seat belts are designed to restrain the person if they get involved in a crash. Since it was made compulsory to wear seat belts the fatality rates have halved and so have the risk of serious injury. Teenagers have the highest chance of being killed when not wearing seat belts which is 67 %. A study in 2009 found: Drivers of cars and vans found seat belts to be 50% effective against fatal injuries, 45% effective against serious injuries and 25% effective against minor injuries. Front seat passengers found seat belts to be 45% effective against fatal injuries, 45% effective against serious injuries, and 20% effective against minor injuries. Rear seat passenger’s found seat belts to be 25% effective against fatal injuries, 25% effective against serious injuries and 20% effective against minor injuries. Though lap belts are effective enough to prevent serious injuries and death, three point seat belts are almost one and half times better at preventing deaths and serious
injuries. ABS brakes When travelling alone a wet road and suddenly need to brake fast normal brakes will apply at once locking the wheels resulting in the car skidding, furthering the stopping distance. ABS brakes use wheel speed sensors to work out if the wheels are trying to lock up during braking. A series of hydraulic valves reduce braking on a wheel which is trying to lock up. This prevents skidding reducing the stopping distance and allowing the driver to maintain control which could very easily prevent a crash.
Seat belts that stay in rest stay in rest. Seat belts that are in motion stay in motion. For example, when a car is in motion the seat belt is in motion. When the car is at rest the seat belts stay at rest. An example for motion is when a driver is driving their car the seat belt is in motion. It is trying to put pressure on the passenger so they don’t get hurt. An example when a seat belt is at rest when the car is not moving at all. There is no pressure acting on the driver. Another example for motion is when someone hits the brakes. Pressure is developing on the body with the seat belts. That is why sometimes seat belts lock and the driver can’t go forward a lot. It is trying to pull back the passenger so it doesn’t get hurt by any objects in front of it. In order to create a seat belt I decided to use straws and tape. It is strong enough to hold back the passenger from hitting anything. The main reason for a seat belt in this project is to put pressure on the
It has been determined by the Supreme Court that it is proper to arrest someone for a violation of a seat belt law if it has been violated in the presence of an officer. All 50 states and the District of Columbia have statutes that permit warrantless misdemeanor arrests by at least some peace officers without requiring any breach of the peace. Because The “Click it or Ticket” program in North Carolina has served as a model for the nation and the Presidential Initiative for Increasing safety belt use Nationwide highly recommends that other communities adopt this program it appears as though safety belt laws will continue to exist for years to come.
According to national teen driving statistics, 16-year-olds, in particular, are 3 (three) times more likely to die in a crash than the average of all drivers, and they have higher crash rates than any other age group. In 2008; 81% of teenage crash deaths were passenger vehicle occupants, 31% of teenage drivers killed had been drinking alcohol, 55% were not buckled up, and 37% of male teenage drivers involved in fatalities were speeding. Teenagers who drink and drive have a greater risk of serious crashes than older drivers with equal blood alcohol concentrations. Teens do not wear seat/safety belts as much as adults. Teens tend to take more risks due to overconfidence in their abilities. These risks include: speeding, tailgating (driving too close to the vehicle in front), running red lights, violating traffic signals and signs, illegal turns, dangerous passing, and failure to yield to pedestrians.
Adolescents tend to find ways to let out their emotions and try to escape their problems, and this unfortunately leads them to make poor decisions that hurt them more than they know that it would be. Alcohol actually is a depressant because it slows down the function of the central nervous system and it cause people to lose coordination and not be able to think straight.
Many people may choose not to wear a seatbelt because they don’t understand how and why they work. To begin with seatbelts are the first line of defense one has against an injury in a crash.
Current seat belt law originated from federal legislation in the 1960s that made it mandatory for all automobile manufacturers to include seat belts in their vehicles as a standard feature. Originally, the purpose of a seat belt was not to protect the occupants in the case of a crash, but rather to physically keep them in the vehicle, as driving was bumpy business.
Seatbelt is a very important component when we all drive a car or other vehicle. The main purpose of seat belts is to provide greater safety to the driver when driving car but at the moment, people do not care about the importance of wearing seatbelt.
We have all heard the excuses before, "It's uncomfortable, I'm only going around the corner", I'd rather be thrown out of a car than be stuck in a seatbelt," and my favorite, "I'm a good driver I don't need to wear one." Well you may be a good driver but there are situations beyond your control such as bad weather, road conditions and not to mention other drivers that can affect your safety. Seat belts can mean the difference between life and death in an auto accident. Wearing a seat belt every time you enter a vehicle is not only the smart thing to do it is the right thing because it saves lives, it's the law and it will save you money.
A driver or passenger travelling in a car is moving at the same speed as the car. If the car suddenly stops, the body of the rider inside will keep moving forward at the same speed. This demonstrates inertia. The tendency of a moving object to keep moving, or of a stationary object to remain at rest. Basically Newtons first law; that a body stationary or moving with constant velocity will want to continue to do so, unless acted on by a force.
The journey from that idea and the airbags that we have now has been very long. Today, airbags are a necessary in every car and are designed to act as an extra safety device aside of seat belts. But a lot of people are looking quite sceptical at the air bag safety, because there was a lot of accidents where the airbag didn’t react or it did react, but it didn’t help but killed the driver or the passenger. Since 1991 there was 238 counted just because of air
A fatal car accident occurs almost every ten minutes in the United States, resulting in 30,800 occupant deaths a year, and even though seatbelts could prevent an estimated 10,000 of these deaths according to Crash Circumstances website (2018), we still see a many people simply will not wear them. There is an estimated amount of six-million people in Missouri according to Missouri state highway patrol website (2016) of those are 4.25 million are drivers, in 2013 there was around 760 fatal car accidents so that means you are around 1:4,000 chance of being in a fatal car accident and 1:8,000 dying in a car wreck. This may seem like low odds, but you take an even greater risk when you are not wearing your seatbelt. After reading many crash statistics posted by National Highway Traffic Safety Administration (2017) and Missouri Highway Patrol (2016), I have become very passionate on the subject of seatbelt safety and noticed there is a problem with these laws. The purpose of this paper is to provide a possible solution to reduce the problem, labeling both positive and negative aspects, and a solution to the problem.
When students are restrained in the school bus with a seatbelt, they are less likely to be hurt in any type of crash. By putting seatbelts we are guarding any type of
Because of these reasons, the use of seat belts is, overall, very important. Not using a seat belt can reward hefty fines, cause society to spend more money, and make death and injury more likely in traffic accidents. All of these things can be avoided by easily putting on a seat belt before
Ethyl alcohol or ethanol, or most often known simply as alcohol, can come in the form of beer, wine, or liquor. A depressant affects the central nervous system, although many would believe it to be a stimulant. Many people get more energetic and stimulated, but this is only because alcohol affects parts of the brain that control judgment. The stimulant effect of alcohol actually amounts to depression of self-control.... ...
Legally in the United States, alcohol is known as beverage that has a minimum age requirement of twenty-one years old. Many people use alcohol as a way to celebrate, socialize or to release stress. To the body, alcohol is classified as a depressant. This means that alcohol disrupts the way the body functions. Ethanol or Ethyl is the main ingredient found in several alcoholic beverages, including wine, beer, and vodka. Ethyl Alcohol is produced by the fermentation of grains and fruits. Ethyl Alcohol is what affects the body causing intoxication. High dose of alcohol can have a severe effect on an individual’s mental state. This can lead to problems concerning mental health, as well as physical health..
