Well, then explain this:
(i) A person who willfully fails to comply with a court order to
attend traffic violator school is guilty of a misdemeanor.
Let me add this from the Los Angeles County Infraction and Misdemeanor Bail Schedule... Footnote #145:
Per Penal Code §§ 19.8 and 17(d), a violation of Vehicle Code § 42005(i), if charged as an infraction, is punishable by a fine not to exceed $250. The infraction bail is $35. (Uniform Traffic Bail and Penalty Schedule, January 2009.)
