Which driver aid numbers are delivered last?

Which driver aid numbers are delivered last?

• A. High driver aid numbers
• B. Low driver aid numbers
• C. Mid driver aid numbers
• D. First number only

Answer: (A)

The concept here is progressive disclosure of driver aids: simpler guidance is shown first, and more advanced or detailed help is provided later as needed. In a staged system, the lower-numbered aids are designed to be easy to process and cover the basics, so they’re delivered early. As the driver becomes more familiar with the situation, higher-numbered aids come in to offer additional support, building on what’s already been presented. That’s why the aids with the highest numbers are delivered last—they add extra guidance only after the driver has been oriented with the simpler cues. Lower-numbered aids would come first, not last; mid-numbered aids would appear earlier than the highest; and giving only the first number would skip the later, more comprehensive assistance.
