An instructor has planned to teach independent rural driving, but the learner arrives exhausted after night shift work and is visibly unfocused. The best professional decision is to:

1. Proceed with the full plan regardless, since the syllabus must be covered
2. Adapt the lesson to a lighter, shorter or more supervised session, or rearrange it, because fatigue undermines learning and safety
3. Let the learner drive the planned demanding route anyway to build resilience
4. Cancel all future lessons with this learner
