Question 6553
Which of the following reasons can explain why the vehicle is the risk factor that appears least often as the main cause of traffic accidents?
- The fact that the average age of vehicles keeps increasing.
- The fact that over the last 20 years, the number of kilometers driven has decreased year after year.
- The major technical improvements made to its design and construction.
Show answer and explanation
Correct answer: The major technical improvements made to its design and construction.
Vehicles are increasingly well designed and built and have more safety systems, so mechanical failures are less often the main cause of a crash. Cars getting older does not explain this, because the likelihood of mechanical failure increases once they reach 8 or 10 years old.
