Right-Front Tire Failure at Interstate Speed
Marcus, 16, is driving 65 mph in the centre lane of I-264 in moderate traffic. You see the right-front tire begin to shred before he feels it: the car snaps hard right, Marcus shouts, clamps both hands on the wheel, jerks the wheel left, and then slams the brake pedal. You are in the passenger seat with a dual brake and a dual-control accelerator cut-off. Behind you, a box truck is following at roughly two car lengths. The vehicle recovers without striking anything, and Marcus pulls onto the right shoulder shaking. The post-drive inspection finds a nine-year-old tire at 26 psi on that corner, with the sidewall date code visible and tread worn near 3/32 inch. The other three tires are at 34 psi.
1. State the correct emergency procedure for a high-speed tire failure and explain how you manage the moment as the instructor, including when you use the dual brake.

The sequence Marcus should learn. Hold the wheel firmly with both hands in a fixed position; keep the accelerator steady or ease off it very gently; do not brake hard; steer straight to maintain the lane until the car has stabilised; then let speed bleed off on its own before applying gentle braking and easing to the right shoulder. Once stopped, hazard lights on, exit on the passenger side away from traffic, stand behind the barrier if one exists, and call for assistance. The reasoning: a failed tire creates strong asymmetric drag on one corner. Hard braking transfers weight forward and away from the remaining good tires, and a sharp steering input on top of that drag is what turns a blowout into a rollover or a crossing of the median.
What Marcus did. Both of his instincts - jerk the wheel away from the pull and slam the brake - are the two most dangerous responses, and both are normal human reactions, which is exactly why the correct response has to be rehearsed to the point of automaticity.
Your role. Your job in the first second is to stabilise, not to fight him for the wheel. Say one short instruction - "steady, hold it straight, off the gas" - and keep your foot covering the dual brake. Use the dual brake only after speed has dropped and the car is straight. Snatching control while the car is unsettled adds a second steering input on top of a struggling driver's.
2. How do you debrief this incident with Marcus so that it builds competence rather than fear, and what should you not do in the immediate aftermath?

Do not continue the lesson as if nothing happened, and do not open with correction. Marcus is shaken, and his first need is to have the event acknowledged. Start with the fact that he kept the car on the road and off the truck's bumper - that is true and it matters.
Structured recall, not lecture. Walk him through three questions in order: what did you notice first; what did you do; what would you do differently. Let him speak before you do. He will usually identify the brake-slam himself, which makes your correction far more durable than if you announce it.
Normalise the instinct, correct the response. Say plainly that grabbing and braking is what almost everyone does the first time and that the reason it is wrong is physical, not moral. Then rehearse the correct sequence verbally three times in the parked car, and physically at low speed in a car park if the vehicle can be driven.
Get him driving again before the day ends. A short low-speed drive on a quiet road prevents the event from hardening into a driving phobia. Do not put him straight back onto the interstate.
What not to do: do not shout during the event, do not replay the dash-cam footage immediately, do not make the incident a cautionary tale in front of peers, and do not tell him he "nearly killed us." That converts a teachable failure into a permanent fear response.
3. What vehicle-safety and pre-drive instruction does the inspection data justify, and where does the instructor's responsibility begin and end regarding the vehicle?
Read the worked answer
Read the data. A nine-year-old tire at 26 psi, worn near 3/32 inch, against 34 psi in the other three, is an underinflation and ageing problem, not bad luck. Nine years is well past the point at which most manufacturers recommend replacement regardless of tread, because rubber degrades from the inside. Underinflation makes the sidewall flex far more than designed, which generates heat - and heat is what causes a high-speed failure. Three tires at 34 and one at 26 also points to a slow leak that had never been found.
What to teach the student. Monthly and pre-trip pressure checks on all four tires plus the spare, using the door-jamb placard rather than the number on the sidewall; tread at 2/32 inch as the legal minimum with replacement advisable well before that; how to read the date code; what a TPMS light actually means, and that it is a low-pressure warning and not a service reminder; and load limits, because a car full of passengers changes the picture.
Where your responsibility sits. You do not own the vehicle, but you control whether you continue to teach in it. Document the defect, notify the owner in writing, and decline to use the car until it is corrected - you cannot certify a lesson conducted in a vehicle you know to be unsafe. Then teach the pre-drive check as a routine every lesson, so the student learns that the walk-around is part of driving, not an optional precaution.
