Accident Terms and Definitions

Frequent or unsafe lane changes
In driver test books there are laws that state what type of passing may be done acording to the yellow lines paited in the road or highway. There are some laws that regulate the distance that a lane change can be made related to an intersection.

Velocity
Speed and direction; used to describe a mode of functioning which is efficient and tightly aligned with conscious intention.

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.

Elderly & Older Drivers
Drivers typically 65 or 70 years old, most states require renewal applicants to appear in person and to pass a vision test.

Choice no fault
In some state a hybrid no fault system known as " choice no fault " exists. In these states, you may choose to be insured under a strict no-fault plan, in which case you're unable to sue an at fault driver and also can't be sued if you're at fault.

Tire Problems
Under-inflation, the most frequent cause of tire failure, is considered the main culprit in the recent Firestone tire-failure fatalities. Uneven or worn-out tires are the next most serious problem and can also lead to tire failure.

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

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.

Reference Point
In angular momentum, the point in space around which the motion of an object is described. The angular momentum of an object is defined in relation to some point, the reference point. The velocity and radius of an object are measured from the reference point.

Failure to yield the right of way
Can be when you proceed forward while disregarding right of way signs or signals for other cars. You may not be the car that is sopossed to go forward.
