Two Drifts, Three Days on a New Prescription
Priya is 16, holds an Iowa intermediate license, and is 20 minutes into a 45-minute lesson on a two-lane road posted at 45 mph. Her father dropped her off and left; pickup is at 5:00 p.m. She has yawned repeatedly, and in the last mile she has drifted onto the right shoulder twice and braked late for a stop sign, stopping with the front wheels past the line. The weather is clear and dry. When you ask, she says she started a new prescription three days ago, slept about five hours, and worked until 10 p.m. last night. She also mentions, casually, that she had a dizzy spell last month where she 'saw spots' for a few seconds while standing up. She wants to finish the route because she has a test tomorrow and needs the practice. There are 25 minutes left on the clock.
1. What do you do in the next 90 seconds, and do you finish the lesson?

Correct first, discuss second. The first shoulder drift gets a verbal cue; the second drift and the late braking get an intervention - hands on the wheel if needed, then a signal and a stop in a safe spot well off the travel lane. Do not continue the route. Two drifts plus late braking plus repeated yawning is impairment-equivalent behavior, and the cause does not matter to the risk in the next mile: a new medication, five hours of sleep, and a late shift all point the same direction. Since her father dropped her off, she is not driving herself home, which removes the hardest part of this decision. Call the parent to collect her, or arrange a ride with the parent's knowledge. Tell her plainly that the lesson is over, that this is not a disciplinary action, and that you will explain why.
2. What do you say to Priya and her father, and where are the boundaries of your role?

Describe behavior, not character. 'You drifted onto the shoulder twice and braked late; those are the signs I watch for when someone is too tired or affected to drive.' Then ask about sleep and the medication, and listen. Do not advise her to stop, start, or change a dose, and do not speculate about whether the prescription causes drowsiness - that is the prescriber's or pharmacist's call. Do tell her exactly what to ask: whether this medication affects driving, especially in the first weeks, and whether the dizzy spell needs evaluation. She is a minor and her father is your point of contact for the lesson, so he needs the facts and the recommendation for medical follow-up. Mention that Iowa's licensing process includes a medical review pathway, so a doctor's input is not a secret she has to hide for fear of losing her license - the system is designed for exactly this.
3. How do you document this, and what does the next lesson look like?
Read the worked answer
Write it the same day: time, route, observed behaviors, the specific intervention, what she told you about sleep and the medication, and who collected her. Keep it factual and keep the medical detail minimal and confidential; do not discuss it with other students, and do not put it in a group chat. The next lesson is conditional. Before scheduling, confirm with the family that she has spoken to the prescriber or pharmacist and has a plan for sleep on work nights - if the dizzy spells are unresolved, no lessons until she has been evaluated. When she returns, start with a pre-drive self-check she runs herself: hours slept, medication timing, how she feels, any warning signs. Then use a low-demand route and build in a mid-lesson stop and honest self-report, so that the skill she practices is declaring fatigue early rather than pushing through it to please an instructor.
