TRAFFIC -- ENFORCEMENT AND GENERAL PROVISIONS
49-1401. RECKLESS DRIVING. (1) Any person who drives
or is in actual physical control of any vehicle upon a
highway, or upon public or private property open to
public use, carelessly and heedlessly or without due
caution and circumspection, and at a speed or in a manner
as to endanger or be likely to endanger any person or
property, or who passes when there is a line in his lane
indicating a sight distance restriction, shall be guilty of
reckless driving and upon conviction shall be punished as
provided in subsection (2) of this section.
(2) Every person who pleads guilty to or is found guilty of reckless
driving for the first time is guilty of a misdemeanor and may be sentenced to
jail for not more than six (6) months or may be fined not more than one
thousand dollars ($1,000), or may be punished by both fine and imprisonment.
Every person who pleads guilty to or is found guilty of reckless driving, who
has previously been found guilty of or has pled guilty to reckless driving, or
any substantially conforming foreign criminal violation within five (5) years,
notwithstanding the form of the judgment(s) or withheld judgment(s), is guilty
of a misdemeanor and may be sentenced to jail for not more than one (1) year
or may be fined not more than two thousand dollars ($2,000), or may be
punished by both fine and imprisonment. The department shall suspend the
driver's license or privileges of any such person as provided in section
49-326, Idaho Code.
(3) Inattentive driving shall be considered a lesser offense than
reckless driving and shall be applicable in those circumstances where the
conduct of the operator has been inattentive, careless or imprudent, in light
of the circumstances then existing, rather than heedless or wanton, or in
those cases where the danger to persons or property by the motor vehicle
operator's conduct is slight. Every person convicted of inattentive driving
under this section shall be guilty of a misdemeanor and may be sentenced to
jail for not more than ninety (90) days or may be fined not more than three
hundred dollars ($300), or may be punished by both fine and imprisonment.
