Tire Marks
Can be used to determine the direction of travel
Can be used to identify the type of vehicleSlide5
Identifying a Vehicle
The track width and wheelbase are used to identify a vehicle
The
track width
is measured from the center of each tire to the center of the opposite tire; remember that the front and rear track width measurements may differThe wheelbase is the distance between the center of the front axle and the center of the rear axleSlide6
Wheelbase and Track WidthSlide7
Turning Diameter
Used to help identify a vehicle
Is the measure of how tight a circle can be driven by a vehicle
In other words, the minimal space required for a car to make a U-turnSlide8
Turning DiameterSlide9
Types of Marks
Skid marks:
Formed when someone brakes suddenly and locks the wheels
Provides evidence of the distance brakes were applied
Calculation of velocity can be made from skid marksSlide10
Types of Marks
Yaw marks
:
Produced when a vehicle travels in a curved path faster than the vehicle can handle and skids sideways
Tires and road surface melt from extreme conditions
Audible squeal and often smoke occursSlide11
Types of Marks
Tire scrub
:
Produced by a damaged or overloaded tire or tires during or immediately after impact
Usually curved, irregular in width
May have striations that look like stripes
Determine area of impact
