- p What is step 1 of the traffic crash management process.
- q ___ is defined as an injury to any person, including the driver, which consists of a physical condition that creates a substantial risk of death, serious personal disfigurement, or protracted loss or impairment of the function of any bodily member or organ.
- r _____ is define as any damage to a vehicle resulting from the direct pressure of any object in a collision or rollover. It usually appears as scrape marks or striations on the body of the vehicle, material rub-off, such as paint from the other vehicle (called paint transfer), rubber, or tree bark, or as a puncture to or imprint on a bumper, guard rail, or other fixed object.
- s Officers can use ___ statements in lieu of written statements.
- t ___
in relation to a crash: the officer can consider the movement of
vehicles during and after collision when determining the path of travel
and assisting in locating the area of collision. Basic physics teaches
that an object in motion continues to remain in motion until acted upon
by an external force. In a crash
investigation, external force is normally another moving vehicle or a stationary object such as a tree or building.
- u The traffic crash management process involves the following ten steps:
- v The
beginning of this part of the skid is called the skid ___ . It is the
start of the skid mark and should be measured. It is usually hard to see
unless closely observed. It is also temporary and may no longer
be visible 15 to 20 minutes after the marks are made.
- w ___ is defined as visible or non-visible signs of injury, such as a bleeding wound or distorted member, usually requiring transportation to a medical facility and hospitalization.
- x ___ are a series of skid marks usually short in length with irregular intervals between them. This pattern appears when a vehicle has a sudden load shift while braking hard. The weight shift causes a bouncing, which results in the skip skid mark. This is more typical of trailer vehicles. A car skidding on a bumpy road also makes this mark.

- ag What is step 5 of the traffic crash management process.
- ah The ____ is when the driver becomes aware of a danger or hazard.
- ai ___
occurs when two objects begin to enter the same space at the same time.
This is where the first injury or damage may occur. Damage will occur
contact is made between vehicles or objects entering the same space. Evasive action may also occur here if no contact is made between vehicles or objects.
- aj A ___ occurs when a vehicle loses tire traction as a result of entering a curve too fast or over steering. The tires in this case continue rotating but slide sideways at the same time. Marks are left from the tires slipping across the roadway once the adhesion limit of the tires is exceeded. The tires produce a screeching sound and leave rubber marks on the roadway. The scuff or yaw marks may be evidence of when the driver began to lose control of the vehicle. They will always be curved and will show a sideways striping or striation from the side motion of the tires.

- bz A ___ is a collision, involving one or more vehicles, that causes property damage, personal injury, or death and is the result of an unintentional act.
- ca ___ are the patterns left by a vehicle with anti-lock brakes when a driver brakes hard. These marks do not resemble the solid skid marks. The function of the ABS is to prevent the wheels from locking by rapidly applying and releasing the brake and thereby allowing the driver to remain in control of the steering.
