The document discusses various automotive safety devices including airbags, seat belts, radar systems, night vision systems, GPS, and emergency braking systems, highlighting their functionalities and importance in reducing injuries during accidents. It explains how safety features like electrochromatic mirrors and heads-up displays help prevent accidents by minimizing distractions and glare. Additionally, it outlines innovations like backup sensing systems and energy-absorbing steering systems that enhance driver protection and lower fatality and injury rates.

6. Safety Devices
• Air Bags
• Seat Belts
• Radio Ranging
• NVS (Night Vision System)
• GPS (Global Positioning System)
• Emergency Braking System

7. Air Bag
• An 'airbag' is a vehicle occupant-
restraint system using a bag
designed to inflate extremely
quickly, then quickly deflate
during a collision.

10. Seat Belt
• If you're sitting in one of the front seats of a
passenger car that gets in an accident, wearing
your seat belt decreases your risk of suffering a
fatal injury by 45 percent, and decreases your
risk of suffering a moderate to critical injury by
50 percent.

13. Radio Ranging
• Radar is an acronym for "radio
detection and ranging." A radar
system usually operates in the
ultra-high-frequency (UHF) or
microwave part of the radio-
frequency (RF) spectrum, and is
used to detect the position
and/or movement of objects.

14. Night Vision
System
• An automotive night
vision system uses a
thermographic camera to
increase a driver's
perception and seeing
distance in darkness or
poor weather beyond the
reach of the vehicle's
headlights. Such systems
are offered as optional
equipment on certain
premium vehicles.

16. GPS
• A GPS navigation system
is a GPS receiver and
audio/video (AV)
components designed for
a specific purpose such as
a car-based or hand-held
device or a smartphone
app. The global
positioning system (GPS)
is a 24-satellite navigation
system that uses multiple
satellite signals to find a
receiver's position on
earth.

18. Electro chromatic
Mirror/Auto Dimming Mirrors
One thing that can really be annoying when you are driving at night is the reflection
of headlights in your mirrors. This feature will automatically darken the mirrors,
which in turn reduces the glare. Today, approximately 10% of all vehicles are
equipped with this feature, and many more vehicles are expected to have this
technology in the near future. This not only helps to prevent accidents, it also helps
people who are extremely light sensitive, and bothered by lights in their mirrors.

19. Heads Up Display
• One should never take their eyes off the road
while they are driving, but we all do. We must
look down to check our speed and other things,
and it can only take a split second for an accident
to occur. A heads up display (HUD) will put the
information you need right across your
windshield, so your eyes never have to look
anywhere but at the road. You will still be able to
watch what you are doing, while being able to find
the information you need quickly and easily.

20. Back Up Sensing
System
This is a wonderful little invention that
makes it so that when you are backing
up, you will be warned if you get too
close to another vehicle or other
object. This is now an option on a
number of larger vehicles, such as RV’s
and SUV’s, and it has greatly reduced
the number of collisions caused by
backing up, and a lot of bicycles in
driveways have been saved because of
this feature.

21. Energy-Absorbing Steering System
This is designed so that it will compress upon impact, lessening the risk of rib injuries to
drivers. This has been proven to work in many instances, and it has reduced the risk of
driver fatalities by 12%, and serious injuries and death risks have been reduced by 38%.
When there is a crash, drivers are often thrown forward, and the steering wheel can
cause serious injuries, making this feature one that you should look for in your next
vehicle.
