Brain Injury: Sharing The Road With Trucks Quiz

Explanation
There are three crashes in every collision. 1) The car crashes into something. 2)The people and things in the car crash into each other and into the car frame and windows, etc. 3)The internal organs crash into each other, such as the brain crashing into the skull, or the heart and lungs tearing apart from one another.

Explanation
The headrest in a car is designed to prevent whiplash, which is a common injury that occurs when the head is forcefully jerked backward and forward during a collision. The headrest provides support to the head and neck, helping to minimize the movement and reducing the risk of whiplash. It acts as a cushion, absorbing some of the impact and providing stability to the head, thus protecting the spine and preventing potential neck injuries.

Explanation
You should always pass trucks on the left because the right-side blind spot is very large and truck drivers have trouble knowing whether cars are there or not.

Explanation
White stopping lines at intersections are carefully measured to give trucks the space they need to turn. Trucks have a larger turning radius compared to smaller vehicles, and stopping behind the white lines allows them to make wider turns without encroaching into other lanes or hitting curbs. This helps to ensure the safety of both the truck driver and other road users by preventing accidents or collisions during turns.

Explanation
Although for cars it is a 3-second rule, for trucks it is a 4-second rule because they have a large blind spot behind the truck.

Explanation
When merging onto the highway, it is important to "pick your spot, get up to speed, and go with the flow." This means that you should choose a suitable gap in the traffic, accelerate to match the speed of the vehicles on the highway, and smoothly merge into the flow of traffic. By getting up to speed, you ensure a safe and seamless merge, minimizing disruptions and potential accidents.

Explanation
Trucks move to the left at intersections because they need to make wide right turns. This is because of their large size and long length, which requires them to swing out to the left in order to safely navigate the turn without hitting any obstacles or pedestrians on the right side. Therefore, it is important for drivers to be cautious of trucks moving to the left at intersections, even if there appears to be enough space to pass them on the right, as they could potentially crush smaller vehicles.

Explanation
When changing lanes in front of a truck, it is important to ensure that you can see the entire front end of the truck in your rear-view mirror. This is because trucks have larger blind spots compared to smaller vehicles. By waiting until you can see the entire front end of the truck, you can be confident that the truck driver can see you and there is enough space for you to safely change lanes without risking a collision. Therefore, the statement is true.

Explanation
Brain injuries are permanent.

Explanation
Alcohol and marijuana are both substances that can have harmful effects on the brain when used over a long period of time. Prolonged and excessive alcohol consumption can lead to brain damage, including shrinkage of brain tissue, impairment of cognitive function, and memory loss. Similarly, marijuana use has been associated with negative effects on brain structure and function, particularly in areas related to memory, attention, and motivation. Therefore, it is true that both alcohol and marijuana can cause severe damage to the brain over time.

Explanation
That part of the brain continues to develop into the 20's.

Explanation
Being thrown from a vehicle during a crash actually increases the risk of severe injury or death. When a person is ejected from a vehicle, they are exposed to the forces of impact and can collide with other objects or the ground. On the other hand, staying inside the vehicle with proper restraints, such as seat belts, provides a higher chance of survival. Seat belts help to restrain the body and distribute the forces of impact across stronger parts of the body, reducing the risk of serious injury.

Explanation
Trucks often weigh more than 40 tons because they are designed to carry heavy loads and transport goods over long distances. The weight of a truck depends on various factors such as its size, type, and the materials being transported. Many trucks, especially those used in industries like construction and mining, are specifically built to handle extremely heavy loads, which can easily exceed 40 tons. Therefore, it is true that trucks often weigh more than 40 tons.

Explanation
The statement suggests that larger vehicles have larger blind spots. This is because the size and shape of a vehicle can obstruct the driver's view, making it harder to see surrounding objects or vehicles. Larger vehicles, such as trucks or buses, typically have larger blind spots due to their size and height. This can pose a safety risk as objects or vehicles in these blind spots may not be visible to the driver, increasing the likelihood of accidents or collisions. Therefore, the statement is true.

Explanation
Brain injury can have various consequences, including the need for a wheelchair, loss of independence, loss of friends/isolation, and even death. The need for a wheelchair may arise if the injury affects motor skills or mobility. Loss of independence can occur if the injury impairs cognitive or physical abilities, making the individual dependent on others for daily tasks. Loss of friends and isolation may result from changes in behavior or personality caused by the injury, leading to strained relationships. In severe cases, brain injury can be fatal, resulting in death.

Explanation
The given statement mentions that there are close to _.4 million brain injuries suffered every year in the United States, and 44,000 a year in Massachusetts alone. The correct answer is 1 because it is the only option that completes the sentence correctly. The statement implies that the missing number before the decimal point should be a digit between 0 and 9, and the only option that fits this criteria is 4. Therefore, the correct answer is 1.

Explanation
Car crashes are the most common cause of brain injuries due to the high impact forces involved in these accidents. During a car crash, the sudden deceleration or impact can cause the brain to move forcefully within the skull, leading to brain damage. The head may strike the windshield, dashboard, or other hard surfaces, causing direct injury to the brain. Additionally, the rapid acceleration and deceleration can result in the brain twisting or rotating inside the skull, causing shearing forces that can damage delicate brain tissue. Therefore, car crashes pose a significant risk for brain injuries.
