The Medication Question on the Day of the Drive
A 19-year-old student, Devon, arrives for a behind-the-wheel lesson. During the pre-drive check he mentions he started a new prescription two days ago for an anxiety condition. He says the label warns about drowsiness and "avoid operating heavy machinery," but he insists he feels fine and only took half a dose this morning. His eyes look slightly glassy and his speech is a bit slow, though he is cooperative and articulate about the medication. He has a scheduled road test in nine days and says he cannot afford to cancel today's lesson. You are the instructor of record. The lesson is scheduled for 90 minutes on city streets and a highway on-ramp.
1. Decide whether to proceed with the lesson, and justify the decision using the applicable standards for fitness to drive.

Do not proceed with the driving portion. The decision rests on three independent grounds, any one of which is sufficient:
- The label instruction. A prescription warning against operating machinery is a direct instruction from the prescriber and manufacturer. "Avoid heavy machinery" includes a motor vehicle. A half dose does not neutralize the warning, and two days is not enough time to establish how the drug affects him.
- Observable signs. Glassy eyes and slowed speech are objective indicators of impairment, regardless of the student's self-report. Self-assessment of impairment is notoriously unreliable, especially for sedating medications.
- The instructor's duty. An instructor who knowingly permits an apparently impaired student to drive is exposing the student, the public, and himself to liability, and is modeling exactly the wrong behavior for a new driver.
The road test in nine days is not a reason to drive today. It is a reason to document the decision clearly and to advise him to consult his prescriber about timing and effects before the test.
2. Describe how you would handle the conversation, the documentation, and the scheduling consequences so that the student is not simply turned away without a path forward.

The conversation. Be direct, private, and non-accusatory. State the observation, not a judgment: "You told me about the drowsiness warning and I'm seeing slowed speech, so I can't put you behind the wheel today." Avoid debating whether he feels fine - feelings are not the criterion. Do not disclose his medical information to anyone else.
The path forward. Offer concrete options: a classroom or observation session today (riding along with another student or watching a hazard-perception exercise) so the time is not wasted; reschedule the behind-the-wheel portion; and advise him to ask his prescriber how long the medication takes to stabilize and whether it affects driving, and to get that guidance documented. Suggest he consider whether the road test date should move.
Documentation. Record the date, the disclosed medication and label warning, the observed signs, the decision not to permit driving, and the alternatives offered. Keep it factual and objective. Note that the decision was safety-based, not disciplinary.
Scheduling. Confirm the reschedule in writing and note that the road-test readiness decision will be made on demonstrated performance, not on the calendar. Do not promise he will be ready in nine days.
3. Devon asks whether he can just "not mention it next time" so the lesson isn't cancelled. How do you respond, and what does this reveal about the instructor-student relationship?
Read the worked answer
Answer plainly: no, and here is why it would hurt him most. Concealing a medication that affects alertness means the instructor cannot structure the lesson around it, cannot watch for the specific signs, and cannot give him an honest readiness assessment. A road-test examiner or a future employer will not extend the same courtesy, and the first place an undisclosed sedating drug shows up is usually a close call.
Reframe the disclosure as a tool, not a confession. Students who tell instructors about medications, vision changes, or new physical limitations get better instruction, not punishment. Make clear that disclosure will never be used to shame him, only to plan the lesson.
What this reveals: the relationship depends on the student trusting that honesty will not cost him. If the only consequence of disclosure is cancellation with no alternative, students learn to hide things. That is why the previous step - offering a classroom or observation session and a clear reschedule - matters as much as the refusal itself. The instructor's job is to make the safe choice also the easy choice.
