Slurred Speech at 40 mph on a Four-Lane Arterial
Halfway through a 60-minute lesson on a four-lane arterial, your 18-year-old student says, "I feel really weird." She is pale, sweating at the hairline, and her speech is slightly slurred. Her hands are shaking on the wheel, and the car has drifted about a foot toward the lane line. At the start of the lesson she mentioned she is diabetic and said she "didn't have time for breakfast." Traffic is moderate at 40 mph. There is a shopping plaza entrance about 150 feet ahead, and a narrow shoulder with a guardrail to your right.
1. What are your actions in the next fifteen seconds, and in what order?
Read the worked answer
Control the vehicle before you assess the patient. A drifting car at 40 mph is the emergency.
- Announce and take over: "I have the wheel." Take the steering wheel; be ready on the instructor brake. Prompt her to keep her foot off the accelerator - or bring the car to a stop yourself if she is not reliably responsive.
- Signal right and slow smoothly. Aim for the plaza entrance 150 feet ahead rather than the guardrail shoulder; a parking lot gives you a safe place to stop, room to open doors, and access for EMS.
- Hazards on, shift to park, keep the key accessible. Do not let her exit into traffic.
- Then assess: is she alert and able to swallow? Can she tell you her name and whether she has glucose with her?
Judgement point: the sequence is stop - secure - assess. Do not start a medical conversation while the car is still rolling toward a guardrail.
2. She is awake and can swallow but has no glucose with her. What first aid do you give, and what do you not do?

This presentation - pale, sweating, shaky, confused or slurring, recent missed meal, known diabetic - is presumed hypoglycemia until proven otherwise. Treat it.
Do:
- Give a fast-acting sugar if she can swallow safely: glucose tablets if available, otherwise regular soda, juice, or hard candy. Roughly 15 grams, then reassess in about 15 minutes; repeat if she is still symptomatic.
- Keep her seated and calm, and stay with her.
- Call 911 if she does not improve after one or two rounds, if she becomes drowsy or unable to swallow, or if you are unsure of the cause.
Do not:
- Give insulin or anything containing a sugar substitute - that worsens hypoglycemia.
- Put food or drink in the mouth of anyone who is drowsy, unable to swallow, or unconscious; if she loses consciousness, place her on her side and monitor breathing.
- Send her home alone or let her drive, even if she says she feels fine afterward.
If she becomes unresponsive and is not breathing normally, start CPR and use an AED if one is available.
3. The episode resolves after glucose. What are your reporting, documentation, and return-to-driving obligations?
Read the worked answer
Resolution of symptoms does not end the incident.
Immediately: do not let her drive, and do not release her to drive herself home. Contact a parent or emergency contact - noting she is 18, so her consent governs who you notify, but she is in your care and impaired, and you should not simply leave her at a curb.
Document: time of onset, observed signs (pallor, diaphoresis, slurred speech, lane drift), the control actions you took, treatment given, response, and who was notified. Keep it factual; it is a health record, not an evaluation of her driving.
Return to driving: require that she be cleared by her physician and that she has a plan - glucose within reach in the car, a meal before lessons, and a check-in routine at the start of each session. Notify the school owner per policy and consider whether this is a condition that affects her fitness to drive under RMV rules.
Confidentiality: share the medical details only with those who need them; the driving log records the lesson was terminated, not her diagnosis.
