IPA IP 2025 Question 33
A question IPA Japan published in 令和7年度 ITパスポート試験 公開問題 問33, translated into English. ITPEC is based on the same exams.
The levels of automated driving are generally divided into “Level 1” through “Level 5.” Which of the following is the most appropriate description concerning the level of automated driving indicated by “Level 3,” which is called “conditional driving automation”?
Explanation
The system drives, but a human must take over when the system can no longer continue — Level 3, conditional driving automation.
The levels of driving automation differ in who is the main driving entity and how far the system can go:
- •Level 1 (driver assistance): a human drives; the system assists with either steering or acceleration/deceleration, such as automatic braking
- •Level 2 (partial automation): a human drives; the system assists with both steering and acceleration/deceleration, such as lane keeping with following the car ahead
- •Level 3 (conditional automation): the system drives under set conditions, and a human must respond when asked to take over
- •Level 4 (high automation): the system drives and handles every situation by itself, but only in limited areas or conditions
- •Level 5 (full automation): the system drives anywhere, without limits
Answer (a)
Why not others:
- •(b) — no human driving at all and no need for a steering wheel or pedals, but only in limited areas, is Level 4
- •(c) — the human drives while the system both steers and controls speed on an expressway is Level 2
- •(d) — the human drives while the system assists with part of the driving, such as automatic braking or preventing a sudden start, is Level 1
Key rule: Levels 1 and 2: the human drives and the system assists; from Level 3 the system drives, and Level 3 alone still needs a human ready to take over.
