Shopping for a Safe Car
If you’re like most people shopping for a new car, safety
ranks high among things you're looking for. Every new car must
meet certain federal safety standards, but that doesn’t
mean that all cars are equally safe. There are still important
safety differences, and some vehicles are safer than others. Many
automakers offer safety features beyond the required federal minimums.
The following safety features should be considered when purchasing
a car:
1. Crashworthiness
These features reduce the risk of death or serious injury when
a crash occurs. You can get a rating of crashworthiness from the
Insurance Institute for Highway Safety’s Web site ( http://www.highwaysafety.org
).
2. Vehicle structural design
A good structural design has a strong occupant compartment, known
as the safety cage, as well as front and rear ends designed to
buckle and bend in a crash to absorb the force of the crash. These
crush zones should keep damage away from the safety cage because
once the cage starts to collapse, the likelihood of injury increases
rapidly.
3. Vehicle size and weight
The laws of physics dictate that larger and heavier cars are safer
than lighter and smaller ones. Small cars have twice as many occupant
deaths each year as large cars. In crashes involving smaller and
larger vehicles, heavier vehicles drive lighter ones backwards,
decreasing the forces inside the heavier car and increasing them
in the lighter car.
4. Restraint systems
Belts, airbags and head restraints all work together with a vehicle’s
structure to protect people in serious crashes. Lap/shoulder belts
hold you in place, reducing the chance you’ll slam into
something hard or get ejected from the crashing vehicle. If you
aren’t belted, you’ll continue moving forward until
something suddenly stops you—often a hard interior surface
that will cause injuries.
Shoulder belts are on inertia reels that allow upper body movement
during normal driving, but lock during hard braking or in a crash.
Belt webbing is stored on the reel, and during a frontal crash
any slack in the webbing can allow some forward movement of your
upper body. Then you could strike the steering wheel, dashboard
or windshield. This problem is addressed in some cars with belt
crash tensioners that activate early in a collision to reel in
belt slack and prevent some of the forward movement.
Airbags and lap/shoulder belts together are very effective. However
in some circumstances, a deploying airbag can cause serious injuries
and even death. The greatest risk of injury occurs when you are
on top of, or very close to an airbag when it starts to inflate.
Choose a car that allows you to reach the gas and brake pedals
comfortably without sitting too close to the steering wheel. Some
cars offer telescoping steering column adjustments that may help.
Side airbags are designed principally to protect your chest.
They may also keep your head from hitting interior or intruding
structures.
Head restraints are required in the front seats of all new passenger
cars to keep your head from being snapped back, injuring your
neck in a rear-end crash. But there are big differences among
head restraints. Some are adjustable, and others are fixed. They
also vary in height and how far they are set back from the head.
To prevent neck injury, a head restraint has to be directly behind
and close to the back of your head. Look for cars that have this
type of restraint. If the restraints are adjustable, make sure
they can be locked into place. Some don’t lock, so they
can get pushed down in a crash.
5. Anti-lock brakes
When you brake hard with conventional brakes, the wheels may lock
and cause skidding and a lack of control. Anti-lock brakes pump
brakes automatically many times a second to prevent lockup and allow
you to keep control of the car. If you were trained to brake gently
on slippery roads or pump your brakes to avoid a skid, you may have
to unlearn these habits and use hard, continuous pressure to activate
your antilock brakes. Anti-lock brakes may help you keep steering
control, but they won’t necessarily help you stop more quickly.
6. Daytime running lights
Daytime running lights are activated by the ignition switch. They
are typically high-beam headlights at reduced intensity or low-beam
lights at full or reduced power. By increasing the contrast between
a vehicle and its backgrounds and making the vehicles more visible
to oncoming drivers, these lights can prevent daytime accidents.
7. On the road experience
Other design characteristics can influence injury risk on the
road. Some small utility vehicles and pickups are prone to rolling
over. "High performance" cars typically have higher-than-average
death rates because drivers are tempted to use excessive speed.
Combining a young driver and a high-performance car can be particularly
dangerous.
