Read the following passage and carefully answer the question that follows:

Every year the lives of approximately 1.3 million people are cut short as a result of a road traffic crash. Between 20 and 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury. Road traffic injuries cause considerable economic losses to individuals, their families, and to nations as a whole. These losses arise from the cost of treatment as well as lost productivity for those killed or disabled by their injuries, and for family members who need to take time off work or school to care for the injured. Road traffic crashes cost most countries 3% of their gross domestic product.

What can be inferred from the passage?

Option A: The economic impact of road traffic crashes is limited to medical expenses.
The passage clearly states, "These losses arise from the cost of treatment as well as lost productivity for those killed or disabled by their injuries." Therefore the economic impact of road traffic crashes is not just limited to medical expenses. We cannot infer it.

Option B: Disability is not a common result of road traffic injuries.
The passage clearly states, "with many incurring a disability as a result of their injury." It can be inferred that disability is a common result of road traffic injuries. Therefore, this is opposite to what is given in the passage.

Option C: Non-fatal injuries from road traffic crashes are not a significant issue.
The passage clearly states."Between 20 and 50 million more people suffer non-fatal injuries" so it can be inferred that it is a significant issue. Therefore, this is wrong.

Therefore, the correct answer is D, road traffic crashes can be prevented with the right measures.

From the given options, option D is the correct choice.
