Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 290 (General Knowledge): A driver may not drive after the 14th hour since coming on duty, following 10 hours off
Why
The 14-hour rule creates a fixed window from when a driver first comes on duty, after 10 hours off, during which driving is allowed; once it expires, driving must stop even if the 11-hour driving limit has not been used up.
