Accident Terms and Definitions

Tripped Rollovers
NHTSA data show that 95% of single-vehicle rollovers are tripped . This happens when a vehicle leaves the roadway and slides sideways, digging its tires into soft soil or striking an object such as a curb or guardrail.

Raised Pavement Markers (R.P.M.)
Non-reflectorized ceramic pavement markers, also known as "Bott's Dotts", are most often used to delineate travel lane lines. Reflectorized RPM's come in many different colors and are used to delineate travel lane lines and outside boundaries.

Affidavit
A written or printed declaration or statement under oath Affirm - The assertion of an appellate court that the judgment of the lower court is correct and should stand.

Soft Tissue Injury
Injuries sustained to the muscle, skin, connective tissue.

Collision Scrub
Occurs during a traffic collision when the downward and rotating forces cause a smearing of tire material on the road surface.

Blood alcohol testing
At all levels of blood alcohol concentration, the risk of being involved in a crash is greater for young people than it is for older people (Mayhew 1986). In 2001, 25% of drivers ages 15 to 20 who died in motor vehicle crashes had been drinking alcohol (NHTSA 2002b).

Interrogatories
Written questions developed by one party's attorney for the opposing party.

Brake failure
Brake failure can happen. Drum brakes are more commen to fail. Modern dual-circuit brake systems have made total brake failure an unlikely event. If one side of the circuit fails, the other side is usually sufficient to stop a vehicle.

Excessive speed & Speeding
Speeding is defined as travelling faster than the posted speed limit, or travelling too fast for the road conditions even at speeds under the posted limit.

Advanced Frontal Airbags
Advanced frontal air bags are designed to meet the needs of the occupant in a variety of specific crash situations. Depending on design, advanced frontal air bag systems automatically determine if and with what level of power the driver frontal air bag and the passenger frontal air bag will inflate.
