(2) Any other devices which, when

fier.

§ 95.412
(CB Rule 12) What commu-
nications may be transmitted?
(a) You may use your CB station to
transmit two-way plain language com-
munications. Two-way plain language
communications are communications
without codes or coded messages. Oper-
ating signals such as ‘‘ten codes’’ are
not considered codes or coded mes-
sages. You may transmit two-way
plain language communications only
to other CB stations, to units of your
own CB station or to authorized gov-
ernment stations on CB frequencies
about—
(1) Your personal or business activi-
ties or those of members of your imme-
diate family living in your household;
(2) Emergencies (see CB Rule 18,
§ 95.418);
(3) Traveler assistance (see CB Rule
18, § 95.418); or
(4) Civil defense activities in connec-
tion with official tests or drills con-
ducted by, or actual emergencies an-
nounced by, the civil defense agency
with authority over the area in which
your station is located.
(b) You may use your CB station to
transmit a tone signal only when the
signal is used to make contact or to
continue communications. (Examples
of circuits using these signals are tone
operated squelch and selective calling
circuits.) If the signal is an audible
tone, it must last no longer than 15
seconds at one time. If the signal is a
subaudible tone, it may be transmitted
continuously only as long as you are
talking.
(c) You may use your CB station to
transmit one-way communications
(messages which are not intended to es-
tablish communications between two
or more particular CB stations) only
for emergency communications, trav-
eler assistance, brief tests (radio
checks) or voice paging.

nications are prohibited?

profane words, language or meaning;
(3) To interfere intentionally with
the communications of another CB sta-

sound effects or any material to amuse
or entertain;
(7) To transmit any sound effect sole-
ly to attract attention;

or any other international distress sig-
nal, except when your station is lo-
cated in a ship, aircraft or other vehi-
cle which is threatened by grave and
imminent danger and your are request-
ing immediate assistance;
(9) To communicate with, or attempt
to communicate with, any CB station
more than 250 kilometers (155.3 miles)
away;

or political campaign; (you may use
your CB radio for the business or orga-
nizational aspects of a campaign, if you
follow all other applicable rules);
