SEATBELTS, SPEED
&COLLISION
INVESTIGATIONPresenter:
Powerpoint TemplatesPage 3
Question 1
Seatbelts save how many lives in Canada each
year?
Powerpoint TemplatesPage 4
Question 2
Seatbelts increase your chances of surviving a collision by ___%?
Powerpoint TemplatesPage 5
Question 3
What percentage of drivers and passengers killed in collisions were not wearing a seatbelt at the time of the crash?
Powerpoint TemplatesPage 6
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.
Powerpoint TemplatesPage 7
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
Powerpoint TemplatesPage 10
Engineered Life Space
• Seatbelts keep drivers and passengers in this space where they are safest
Powerpoint TemplatesPage 16
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
Powerpoint TemplatesPage 17
Speed
When damage exceeds the vehicle design, the engineered life space is minimal = a fatal collision

Collision Reconstruction
Collision Scene Investigators
(C.S.I.)
Powerpoint TemplatesPage 22
Steps to collision reconstruction
• Identify all evidence;
• Analyze damage profiles of involved vehicles;
• Follow the evidence from the vehicles to find the area of impact;
• Determine approach of each vehicle based on your findings.
Powerpoint TemplatesPage 23
The Dispatch
• Two (2) vehicle collision
• One confirmed fatality
• East-west stretch of highway

Hints
• Think physics…throw two die-cast cars together and see where they end up.
• Look at the fluid spray and final rest of the vehicle to see where they started.
• Try to align the damage on each vehicle.
• Try different ideas and see which one makes the most sense given the evidence.
• Then determine which vehicle was at fault.ult.
