To earn a private pilot's license, one must show proficiency in
overcoming emergency situations. But a motorist gets a license by
demonstrating little more than a well-executed three-point turn and
parallel parking. The first time a typical driver is truly asked to
demonstrate accident-avoidance expertise, lives are on the line.
In this three-part series, I'll offer tips on how to survive driving
emergencies. These I learned — often the hard way — as a racecar driver,
vehicle and tire tester, and high-performance driving instructor.
In this first part, I'll explain how to survive tire failures and
stuck throttles. In Part 2, we will tell you how to make an emergency
stop and how to drive around an emergency with the help of ABS. Part 3
will explain what to do if you run off the road and will also teach you
how to manage sliding front tires or skidding rear tires. And if you
think you already know how to handle these emergencies; trust me — you
don't.
Emergency #1: Tire Blowout
To survive a tire blowout, pretend you're the bad guy in a police
chase: Push the gas and drive straight ahead. The shotgun-blast noise of
a tire blowout makes most law-abiding drivers do exactly the wrong
thing: attempt to slow down quickly and get off the road. With a
rear-tire failure, any turning at high speed will likely result in a
crash.
I've taught hundreds of drivers how to correctly handle a tire
blowout: I sat in the passenger seat and exploded a gaping hole in the
tire with plastic explosive. Not one lost control. Here's how they did
it.
If a tire blows:
- Squeeze the gas pedal for a couple of seconds. This puts you in
control of the car and directs the car straight down the road. It also
prevents you from committing the mortal sins of braking and turning.
After a couple of seconds, gently and smoothly release the accelerator
pedal. The drag force of a completely flat tire is so potent that
pushing the gas will not allow the vehicle to go faster.
- Most importantly, drive straight down your lane. Keep your feet away from the brake (or clutch).
- Allow the car to coast down to as slow a speed as is safe (30 mph is good). Engage your turn signal and gently
turn toward the shoulder of the road that's on the same side as the
blown tire: This lessens your chance of losing control and will make the
tire change safer. If the situation requires, you may ever so lightly squeeze the brakes.
Almost all highway blowouts and tread separations occur with the car
traveling in a straight line on a very hot day at high speeds with an
underinflated tire. The repeated flexing of an underinflated tire causes
the failure. Check your tire pressures!
Emergency #2: Tread Separation
Though the recovery techniques are nearly identical, a tread
separation is more dangerous than a blowout. This is where the tread
rubber and underlying steel belt partially or completely come off the
tire. This creates a giant Weed Eater with a blade of steel-backed
rubber spinning around at about 1,000 rpm. It'll scythe through the fuel
tank, brake lines, inner fender panels, rear seats, side windows and,
of course, flesh and bone.
An impending tread separation is usually announced by a consistent
thumping noise, which will increase to a slapping sound, and then a
metal-tearing jackhammer pounding. Sometimes this process takes days,
other times only seconds. If you hear this, immediately slow down and
take the tire to a professional for inspection. If you can see damage,
put on the spare before proceeding.
If the tread begins to fly off:
- Squeeze the gas pedal for an instant and gently release it.
- Drive straight down your lane.
- Allow the car to coast down as much as is safely possible. You will likely have to apply the brakes lightly in order to reach a safe turning speed.
- Engage your turn signal and smoothly turn toward the shoulder of the road that's on the same side as the damaged tire.
Another reason why tread separations are more dangerous than blowouts:
When the tread leaves the tire, the bad noise stops and some people
think the car has magically cured itself. But instead of rolling along
on grippy rubber, they're riding on fabric. Polyester will offer little
grip when they take that next freeway off-ramp.
Emergency #3: Stuck Throttle
Thanks to things like loose floor mats and a poorly placed racecar
throttle cable, I have experienced stuck throttles. Although this will
be a rare occurrence for most drivers, if your engine starts racing away
uncontrollably, it must be stopped
immediately.
Take these actions:
- If the engine started racing when you pushed the brake, release
the brake. If the engine stops racing, you were actually pushing the gas
by mistake.
- Put the transmission in Neutral (and/or push in the clutch). Don't
worry about the engine when you shift into Neutral: Engine speed
limiters on modern cars will prevent damage. And it's OK if you get
Reverse: The engine will either stall or act as if it were in Neutral.
- If you can't get Neutral, switch off the ignition as a last
resort. Today's cars don't allow the key to turn to the locked position
if the car is not in Park, and the car will be much harder to steer once
the engine is off since the power-assist will not be working.
Fortunately, with the engine off, there's still plenty of reserve
braking power to stop the car. Of course, if the car is equipped with a
newfangled keyless ignition, getting Neutral may be your only hope.
If you're a passenger in this situation and the driver fails to act, you
can reach over and put the car in Neutral or switch off the engine. But
to have any hope of acting properly with a stuck throttle, both driver
and passenger must
practice first. Find a training partner and
an empty parking lot. First practice with the car stopped, just to make
sure you know the drill. Move the shift lever from Drive to Neutral.
Then turn the key off. Next, restart the car and accelerate to no more
than 10 mph, then push the gas pedal to the floor (to simulate a stuck
throttle) and hold it there through the rest of the exercise.
Immediately, put the car in Neutral and switch off the key. Repeat the process but with the
passenger working the shifter and key while you're still in the driver seat. Then, swap seats and repeat.
Emergency #4: Sudden Acceleration
Also called "unintended acceleration," this is identical to a stuck
throttle...except it's not a mechanical failure but rather the driver
accidentally pressing on the gas. As an instructor, I have had numerous
panicked students push the gas in the mistaken, but unshakable, belief
they were on the brakes. (Left-foot brakers more familiar with
automatics frequently push the clutch.)
Know this: In every well-maintained modern car, the brakes will
easily overpower the engine. If you're truly pushing the brakes as hard
as you can, the car will stop even with the engine going full speed.
The corrective actions for sudden acceleration and a stuck throttle are identical. Check the list above.
Coach Tom was a stereotypical high school driver's ed teacher. But
with one exception: He had a mean streak. When we made a driving
mistake, he hit us on the head with a screwdriver handle. While we were
driving. When we returned to the classroom, he hit us with a paddle:
Imagine a from-the-heels stroke from a guy with biceps better than my
leg. While showering after phys ed, everyone knew who'd gotten a Coach
Tom whack by the purple streak, punctuated by dots, across their
bottoms. The dots were from the holes he drilled in the paddle — to
reduce air drag.
Although I've used corporal punishment in my years as a driving
instructor, I sometimes think of Coach Tom when I'm teaching students to
perform a successful crisis stop. Whether your car has antilock brakes,
it's important that you know exactly what to do in an emergency stop
situation. Get it right and you'll probably avoid an accident. Get it
even a little bit wrong and you'll be getting intimate with another
vehicle or a ditch.
Emergency #5: Crisis Stop, Without ABS Without an
antilock brake system (ABS), a good emergency stop requires a deft
touch. You still must push the brake pedal hard, but not so hard that
you skid the tires. Your goal: Be an organic version of ABS and bring
the tires to the point they've
almost stopped rolling. If they
completely stop, grip drops precipitously and you must release brake
pressure until the tires start rolling and then reapply brake pressure.
Remember, if you lock the brakes, the car will not steer at all. In this
situation, many drivers turn the wheel
completely to the right
or left: If they release the brake before the car comes to a stop, it
will dart whichever way the wheels are pointed.
To practice: Find an empty parking lot. Start moving. Now
squeeze
the brake pedal. Increase the pressure until you hear just the barest
hint of tire squeal. It's a "squeal of delight" and signals the tires
are very close to their peak grip. But if the tires howl like a dog in
pain, they've stopped rolling and grip has dropped. Release and reapply
the brakes.
In an actual emergency, if you can't keep a non-ABS car at the
squeal-of-delight level, you'll stop quicker with the howling
dog-release-howling dog process than if you fail to push the brake pedal
hard enough.
Without extensive practice, braking while turning
without
ABS is like taking a double black diamond ski slope: It can be done well
only by those with skill and experience. But it's difficult and
expensive: You
will tear up tires and you may lose control. Many rental cars lack ABS: You take it from there.
Emergency #6: Crisis Stop With ABS If your car has ABS and you face a road-blocking emergency, here's what you do:
- Stomp the brake pedal to the floor. Kick it as if you're trying to snap it off.
- Stay hard on the pedal until the car comes to a complete stop. Hold the brake pedal to the floor as if you were pinning the head of an angry rattlesnake.
Practice before the actual emergency: Find a dead-end street or an empty
parking lot. Start at a low speed, say, 25 mph. Stomp and Stay. The
first time, you will almost certainly not push the brake hard enough,
nor will you stay on the pedal until the car comes to a
complete
stop. The complete stop is important. Do it again at higher speeds.
Ignore bad noises. Other than slightly accelerated brake and tire wear,
you're not hurting the car. (I had one student run off the road because
she wouldn't push the brake pedal hard enough: "I was afraid of
skidding," she said. "You'd rather crash than skid?" I asked. Where's
Tom's screwdriver?)
Emergency #7: Accident Avoidance Maneuvers Using ABS There's a third "S" that goes with ABS's "Stomp and Stay." It's
Steer
(around the obstacle). One of the great benefits of ABS is that it
allows you to steer even while pushing hard on the brake. In radically
oversimplified terms, it transfers a little bit of the tire's braking
power into turning potential.
But a little bit of steering goes a very long way, and many drivers
way overdo this part. I've had numerous students turn the wheel
completely
in one direction. The problem is that the instant the driver releases
the brake pedal, the front tires are relieved of their braking duties
and have 100 percent cornering power available, which sends the car into
oncoming traffic or off the road.
Here's your parking lot practice mission: Set up a row of
water-filled plastic soda bottles perpendicular to your path. If you
have ABS, stomp the pedal to the floor, stay hard on the pedal and try
to steer around them. It's simple and fun as well.
In this final installment, I'll tell you how to react to and recover
from common driving mishaps, including dropping two wheels off the road
and a front- or rear-tire slide. Although such incidents occur
frequently in normal driving situations — especially on roads beset by
heavy traffic or hazardous weather conditions — many people don't know
what to do in the moment, and the results can be grisly. Your best line
of defense is knowledge and experience.
Emergency #8: Dropping Two Wheels off the Road This
should be the easiest to handle of the 10 emergency situations, yet it
results in a large number of fatalities each year. The answer is as easy
as this: If you drop two wheels off the road, don't be in a hurry to
get back on the pavement.
- Smoothly remove pressure from the gas pedal. Stay away from the
brake pedal unless it can't be avoided (e.g., if you're headed downhill
or there's an upcoming obstacle). Here's where ABS would be worth its
weight in hundred-dollar bills.
- Drive parallel to the road: Allow the car to coast down to, say, 35 or 40 mph.
- Gently turn the wheel a very small amount: If you have to turn more than 5 degrees, you're going too fast. Let the car slow down more.
- If you face an obstacle, brake harder but don't try to reenter
with more than 15 degrees of steering. The reason: If you have to turn
the wheel, say, 45 or 60 degrees to get back on the pavement, the front
tires will fully regain traction before the rears and either you'll spin
out — likely hitting what you were trying to avoid — or shoot across
the road into other traffic.
I once ran completely off a racetrack at 110 mph in an important turn. I
straightened the steering up and allowed the car to slow down a bit.
And I
eased it back over onto the pavement. That mistake could have been tragic, but instead it cost me less than one second.
Even the curves you'll find on interstate highways need only the grip from two tires to stay firmly planted on the road.
Emergency #9 Front-Tire Slide Manufacturers work
hard to make their cars lose front traction before rear grip. When front
tires lose grip, most drivers' natural reaction is the correct
reaction; that is:
- Say "Oh, fudge" (or similar) and have your adrenal gland increase your heart rate.
- Remove your foot from the gas pedal (and stay away from the brake pedal).
- Leave your hands where they are. More steering won't help and might hurt.
- Wait for the traction to return.
- Pray that the grip comes back before you get to the trees or concrete barriers.
Turning the wheel more or stepping on the brake is like writing
additional checks from an already overdrawn account: You're already
asking for more grip than the tires can provide. But something bad can
happen if you turn the wheel more and the traction suddenly returns.
Let's say it was a narrow strip of ice. On the other side of the ice,
the road is barely even damp. The tires now have
plenty of grip. And they think you just asked them to make a very hard left into oncoming traffic. "Yes, sir!"
Emergency #10: Rear-Tire Slide Words can no more
teach you how to catch a rear-tire slide (stock car drivers call it
"loose") than videos can teach you how to hit a curveball. Unlike a
front-tire slide, you cannot successfully react to a rear-tire slide;
you must anticipate it. If you don't anticipate it, you
will spin out.
Then, you must act appropriately, putting in the correct amount of
countersteering, anticipating the return of rear traction and removing
the precise amount of countersteer at the correct rate. In driver's ed,
Coach told you to turn in the direction of the skid. Did he ever say
that at some point you've got to
unwind the steering? Didn't think so.
There are a few moderate-cost ways to learn how to catch a sliding
tail. The biggest bang for the buck is the "slick track" go-kart tracks
found at many fun parks. The next step up is the indoor kart tracks
found in most metro areas. When you're among the fastest drivers around
the track, you're probably adequate when it comes to catching a
rear-tire slide. A rear-drive car and a snow-covered parking lot also
offer potential for practice — along with an equal chance for the cops
to come visiting.
Third would be doing the skid-pad course at a performance driving school. Lots of terrific practice under professional guidance, but it's lots of money, too.
On the highway, though, no "Bs" are given for catching a sliding tail: There are either "As" or "Fs."
Here's my recommendation for those who can't get enough practice, to
enable them to always perfectly deal with the loss of rear traction: The
instant a rear slide makes you say "Oh, shoot" (or similar),
pound
the brake pedal to the floor and hold it there until the car comes to a
complete stop. Then, count to three before proceeding. If you release
the brakes before you've come to a complete stop — even if you're
traveling but 5 mph — your car is going to go whichever way the tires
are pointed, and that may cause you to hit something you just avoided.
Racecar fans have often seen a driver spin out at 175 mph and
miraculously miss the wall, but while going no more than 25, release the
brakes and smash into the wall or another car. This means the driver
lost track of which way the steering wheel was pointed.
If you haven't gotten the message already, each of these tips on how
to successfully survive a driving emergency must be practiced to be
properly employed. For each, we've offered low- (or no- ) cost tips on
how to get some training.
Here's an affordable way to practice most of these tips at once:
Car-club autocrosses, also called Solo II. These are low-speed (less
than 60 mph) one-car-at-a-time, against-the-clock competitions usually
held in parking lots. The only things to hit are plastic traffic cones.
Any well-maintained street car is eligible and entry fees are typically
less than $50. (Check out the Sports Car Club of America for more.) Some clubs will loan helmets to first-timers and many hold free or low-cost driving schools.
While autocross won't hurt your car other than slightly accelerated brake wear, it
will
tear up your tires. You could wait until you need new tires to enter an
event. To enable my children to practice the tips, I bought a set of
"take-off" steel wheels on eBay for $75 and picked up a cheap set of
tires.
While not inexpensive, the amount I spent on my teenagers' hands-on
education was but a fraction of the cost of bodywork, much less hospital
bills. And I sleep better at night with the knowledge that they know
how to deal with common driving emergencies.
