"There
is valid state interest
in requiring
motorcyclists to wear
helmets while driving,
and therefore provision
of this section
prohibiting driving of
motorcycle without
helmet is valid
constitutional extension
of state's police
power." State v.
Beeman (App. 1975)
25 Ariz.App. 83, 541
P.2d 409.
"Primary
purpose of provision of
this section requiring
wearing of protective
headgear while operating
a motorcycle is to
prevent injury to
motorcyclists from
cranial trauma."
(therefore) "In
light of highway
dangers, provision of
this section requiring
wearing of protective
headgear while operating
a motorcycle is
constitutional exercise
of police power in area
of highway safety."
State v. Also (App.
1969) 11 Ariz.App. 227,
463 P.2d 122.
