Range of Motion, Range of Options
Mrs. R, 79, was referred by her daughter after a low-speed parking-lot collision. She drives a 2011 sedan with no adaptive equipment. She had a left total knee replacement eight months ago and reports she "doesn't turn her head like she used to"; measured cervical rotation is about 40° left and 50° right. She wears bilateral hearing aids and takes a prescribed antihistamine that leaves her "a little foggy" in the mornings. She wants to keep driving to church, the pharmacy, and her granddaughter's school, all within four miles of home. Her daughter calls you beforehand and asks you to "tell her she has to quit."
1. Sort the case: what is within your scope as an instructor, and what must be referred - and to whom?
Read the worked answer
Within scope (functional, teachable, observable):
- Mirror setup and a blind-spot procedure that compensates for 40–50° of rotation.
- Seat, headrest, and steering-wheel position relative to the knee replacement; confirming she can move between brake and accelerator decisively and can brake hard without pain.
- Route planning: right-turn-biased routes, avoiding unprotected lefts across four lanes and avoiding rush hour.
- Hearing-aid check at the start of each lesson, and a visual scan habit for emergency vehicles.
Must be referred (outside scope):
- The "foggy mornings" is a medication question. You do not advise her to stop or change a prescription. With her consent, she takes it to her pharmacist or prescriber, and you schedule lessons in the afternoon in the meantime.
- Persistent limited rotation with no explanation belongs in a medical conversation, and the DMV's driver reexamination mechanism exists for exactly this - a family member or physician can initiate it, and so can the DMV.
- A comprehensive driving evaluation by an occupational therapist with driving-rehabilitation training is the right instrument for a fitness-to-drive question.
What you must never do is issue a medical opinion or declare her unfit. You teach, you observe, you report honestly.
2. How do you adapt the vehicle and the lesson to her actual limitations without treating her as fragile?
Read the worked answer
Vehicle:
- Reposition the right mirror a touch wider and add a convex blind-spot mirror; that converts a head-turn problem into a glance problem.
- Adjust seat height and the steering wheel so her sightline over the wheel is clear and her right leg has full pedal travel.
- Windows up, radio off - the hearing aids need the cabin quiet.
Procedure:
- Replace "look over your shoulder" with a defined sequence: mirror, signal, lean-and-glance (a torso lean buys rotation the neck will not give).
- Pre-agreed hand signals and clear, face-to-face speech; do not talk while she is scanning a complex intersection.
- Right-turn-biased route design for her actual trips - church, pharmacy, school - so the practice is the driving she actually does.
Tone: Address her, not the daughter. Use her goals as the frame: independence to church and the pharmacy is a mobility outcome, not a driving outcome. Praise specific execution. Where the evidence supports a restriction (daylight only, local streets, no left turns across heavy traffic), offer it as a plan she chooses, not a sentence being handed down.
3. How do you respond to the daughter's request, and what do you document?
Read the worked answer
To the daughter:
- You cannot discuss Mrs. R's performance with her without Mrs. R's consent - not the lesson content, not the errors, not the assessment. Say that plainly and warmly.
- You can explain your role: you teach and you report observations to the student; you do not determine fitness to drive. You can tell her the legitimate channels - the DMV reexamination request, and an OT driving evaluation - and note that she can use them herself.
- You can say what you recommend generally: that the foggy-morning medication question should go to the pharmacist with Mrs. R's knowledge.
- Do not promise to "talk her out of it," and do not promise to protect the daughter's position.
To Mrs. R: Be honest at the end of the lesson about what you saw and what you'd change. If you observe something genuinely unsafe and she will not address it, say so directly and put the referral in writing to her - that is a duty, not a betrayal.
Document: lesson dates and durations, vehicle and equipment configuration, the observations (rotation, hearing-aid status, medication comment as she reported it - no diagnosis), the route, the skills taught, and the fact that referral options were discussed. Objective language only; no speculation about her competence or her family.
