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 Web site (
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 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.
-
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
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.
-
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.
