A Tire Blowout at 65 With a Guardrail on the Right
You are driving a 2016 sedan northbound on a divided highway near Flagstaff at 65 mph. Your right rear tire suddenly blows out. The car pulls hard right toward a metal guardrail about 40 feet away. Your left lane is clear for several hundred feet. You can hear the flapping of rubber, and the steering wheel jerks in your hands. Your first instinct is to stomp the brake and yank the wheel left. Your tire pressure warning light had been on for two days, and the tread on that tire looked low when you last checked.
1. What is the correct immediate response to the blowout, and why are your instincts wrong?
Read the worked answer
Correct response:
- Grip the wheel firmly with both hands and hold it steady.
- Ease off the accelerator and let the car slow gradually.
- Steer gently to maintain your lane, making small corrections against the pull.
- Once speed is reduced, move to the shoulder or a safe spot and brake gently.
Why instincts fail:
- Stomping the brake shifts weight forward and can cause the car to spin, especially with a failed rear tire.
- Yanking left can overcorrect into the next lane or trigger a rollover at highway speed.
- Panic steering amplifies the pull rather than countering it.
The goal is to keep the car stable while it slows, then get off the roadway.
2. How do the guardrail 40 feet away and the clear left lane shape your steering choice?
Read the worked answer
The guardrail is close, so you have very little room to drift right. The clear left lane gives you an escape option, but only if you can change lanes smoothly.
- Prioritize holding your lane. Small, smooth corrections are safer than a hard left move at 65 mph.
- If the pull is too strong, signal and ease into the left lane only when you have confirmed it is clear and can do so without a sharp input.
- Do not aim for the guardrail. If contact is unavoidable, hit it at a shallow angle rather than head-on.
- Slow before maneuvering. Lower speed reduces the force of any impact and improves control.
After the car is stable and slowed, move as far from traffic as possible and turn on hazard lights.
3. What maintenance failures contributed, and what should you do after you stop?
Read the worked answer
Contributing failures:
- Ignoring the pressure warning for two days. A slow leak can lead to overheating and sudden failure.
- Low tread. Worn tires are more prone to blowouts and hydroplaning.
After stopping:
- Get everyone out on the safe side, away from traffic, if you are on a shoulder.
- Turn on hazard lights and set out a warning device if you have one.
- Call for roadside assistance rather than changing a tire next to fast traffic unless it is clearly safe.
- Inspect the other tires and check pressures.
- Replace the failed tire and address the warning light before continuing.
Prevention: check tire pressure monthly, inspect tread, and never ignore a persistent warning light.
