Definitions for "Negligence Per Se"
This is when a public duty is violated and negligence occurs.
An act or omission regarded as negligence without argument or proof because it violates a standard of care defined by statute or is so obviously contrary to common prudence. Restricted in Washington since 1986; see RCW 5.40.050.
Negligence which is self-evident. Negligence per se is sometimes established by statute: e.g., violation of a motor law may in itself indicate negligence.
an act or failure to act that is considered unreasonable conduct as a matter of law without the need to consider surrounding circumstances
