Which of the following statements is true regarding vehicle safety?

The statement that older vehicles may not meet safety standards is true because safety regulations and technology have evolved significantly over the years. Newer cars are typically designed with modern safety features that older vehicles may lack, such as advanced airbag systems, stability control, and crash avoidance technologies. As safety standards are updated, older vehicles, which were manufactured before these advancements were implemented, might not meet current requirements. This gap can pose risks to drivers and passengers in older vehicles, making it crucial for vehicle owners to ensure that their cars are not only functional but also up to date with safety measures.

In contrast, the other statements are inaccurate. The notion that only new cars are safe overlooks the fact that many older vehicles can be well-maintained and safe, provided they meet the necessary safety standards and are kept in good condition. As for maintenance, regular upkeep is essential for any car, new or old, to ensure it operates safely. Lastly, low speeds do not completely eliminate crash risks; accidents can still occur at low speeds, and the likelihood of injuries can depend on various factors, such as seatbelt use and vehicle design.
