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:
- 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 website at http://www.highwaysafety.org./
- 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.
- 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.
- 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 injure you.
- 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, inflating airbags cause serious
injuries and even death. The greatest risk of injury from
an inflating airbag is if you’re 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 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’re 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, maker sure they can be locked into place.
Some don’t lock, which means they can be pushed down in a
crash.
- 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.
- Daytime running lights
The ignition switch activates these lights. They are typically
high-beam headlights at reduced intensity or low-beam lights at
full or reduced power. By increasing the contrast between vehicles
and their backgrounds, making the vehicles more visible to oncoming
drivers, these lights can prevent daytime accidents.
- 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 the drivers are tempted to use excessive speed.
Combining a young driver and a high-performance car can be particularly
dangerous.
