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 Web site (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.
