Almost 50%

Question 3
What percentage of drivers and passengers killed in collisions were not wearing a seatbelt at the time of the crash?
Almost 40%

What happens to you during a crash?
• Think about:– When the car stops suddenly.– If you didn’t have a seatbelt on.– The speed of vehicle before the
crash.

So Are You In or Are You Out?
You are travelling at 56 km/hr.
You hit something and are not wearing your seatbelt
F = ___________lbs x 20.608 (force) your body weight (deceleration of vehicle,
roadway friction and gravity)
So at 56 km/hr on impact, the force (F) exerted on your body is ___________ lbs
It is your seatbelt that holds you in

Engineered Life Space
• Vehicles are designed with an engineered life space which can withstand the force of most impacts

Engineered Life Space
• Seatbelts keep drivers and passengers in this space where they are safest

How does speed affect your driving?
• The faster you drive:– the longer it takes to stop– the harder you hit– the more damage to you and the
vehicle

Speed
When damage exceeds the vehicle design, the engineered life space is minimal = a fatal collision
