Brain Injury: Sharing The Road With Trucks Quiz

1. What safety device in the car is meant to prevent whiplash?

Headrest

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.

2. You should stop behind white stopping lines at intersections because they're carefully measured to give trucks the space they need to _________.

Turn

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.

3. When merging onto the highway, you should "pick your spot, _____ ___ ___ _______, and go with the flow."

Get up to speed

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.

4. Be careful of trucks that move to the left at intersections. Even though you have room to go by them on the right, they could crush you. Trucks move to the left because they make ______ ______ ________.

Wide right turns

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.

5. The most common cause of brain injuries is ______ ___________.

Car crashes

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.

6. You should keep a 4-second following distance behind large trucks in normal weather and road conditions (and add more time for bad weather and/or road conditions).

True

False

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.

7. You're more likely to survive a crash if you're thrown from the vehicle.

True

False

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.

8. The bigger the vehicle, the bigger the blind spots.

True

False

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.

9. Until you can see the whole front end of the truck in your rear-view mirror, you should not change lanes in front of a truck.

True

False

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.

10. Alcohol and marijuana both cause severe damage to the brain over time.

True

False

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.

11. Brain injuries heal over time, but it takes a long time.

True

False

Brain injuries are permanent.

Explanation

12. The frontal lobe, which is the part of the brain that controls personality, emotions and decision-making, is fully formed by age 18.

True

False

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

Explanation

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

13. Trucks often weigh more than 40 tons.

True

False

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.

14. Which blind spot on a tractor-trailer truck is the largest and usually the most dangerous?

The left side

The right side

The front

The back

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.

15. Four common results of brain injury are:

Financial gain by way of a court settlement

Need for a wheelchair

Loss of independence

Loss of friends/isolation

Death

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.
