on the floor of a truck bed equipped with sides, unless prohibited by State law.

$4.23 Operating under the influence of alcohol or drugs.

(a) Operating or being in actual physical control of a motor vehicle is prohibited while:

(1) Under the influence of alcohol, or a drug, or drugs, or any combination thereof, to a degree that renders the operator incapable of safe operation; or

(2) The alcohol concentration in the operator's blood or breath is 0.10 grams or more of alcohol per 100 milliliters of blood or 0.10 grams or more of alcohol per 210 liters of breath. Provided however, that if State law that applies to operating a motor vehicle while under the influence of alcohol establishes more restrictive limits of alcohol concentration in the operator's blood or breath, those limits supersede the limits specified in this paragraph.

(b) The provisions of paragraph (a) of this section also apply to an operator who is or has been legally entitled to use alcohol or another drug.

(c) Tests. (1) At the request or direction of an authorized person who has probable cause to believe that an operator of a motor vehicle within a park area has violated a provision of paragraph (a) of this section, the operator shall submit to one or more tests of the blood, breath, saliva or urine for the purpose of determining blood alcohol and drug content.

(2) Refusal by an operator to submit to a test is prohibited and proof of refusal may be admissable in any related judicial proceeding.

(3) Any test or tests for the presence of alcohol and drugs shall be determined by and administered at the direction of an authorized person.

(4) Any test shall be conducted by using accepted scientific methods and equipment of proven accuracy and reliability operated by personnel certified in its use.

(d) Presumptive levels. (1) The results of chemical or other quantitative tests are intended to supplement the elements of probable cause used as the basis for the arrest of an operator charged with a violation of paragraph (a)(1) of this section. If the alcohol con

centration in the operator's blood or breath at the time of testing is less than alcohol concentrations specified in paragraph (a)(2) of this section, this fact does not give rise to any presumption that the operator is or is not under the influence of alcohol.

(2) The provisions of paragraph (d)(1) of this section are not intended to limit the introduction of any other competent evidence bearing upon the question of whether the operator, at the time of the alleged violation, was under the influence of alcohol, or a drug, or drugs, or any combination thereof.

§4.30 Bicycles.

(a) The use of a bicycle is prohibited except on park roads, in parking areas and on routes designated for bicycle use; provided, however, the superintendent may close any park road or parking area to bicycle use pursuant to the criteria and procedures of §§1.5 and 1.7 of this chapter. Routes may only be designated for bicycle use based on a written determination that such use is consistent with the protection of a park area's natural, scenic and aesthetic values, safety considerations and management objectives and will not disturb wildlife or park resources.

(b) Except for routes designated in developed areas and special use zones, routes designated for bicycle use shall be promulgated as special regulations.

(c) A person operating a bicycle is subject to all sections of this part that apply to an operator of a motor vehicle, except §§ 4.4, 4.10, 4.11 and 4.14.

(d) The following are prohibited:

(1) Possessing a bicycle in a wilderness area established by Federal statute.

(2) Operating a bicycle during periods of low visibility, or while traveling through a tunnel, or between sunset and sunrise, without exhibiting on the operator or bicycle a white light or reflector that is visible from a distance of at least 500 feet to the front and with a red light or reflector visible from at least 200 feet to the rear.

(3) Operating a bicycle abreast of another bicycle except where authorized by the superintendent.

notices or

advertise

$5.2 Alcoholic beverages; sale of intoxicants.

(a) The sale of alcoholic, spirituous, vinous, or fermented liquor, containing more than 1 percent of alcohol by

weight, shall conform with all applicable Federal, State, and local laws and regulations (See also §2.35 of this chapter.)

(b) No such liquor shall be sold on any privately owned lands under the legislative jurisdiction of the United States within Glacier, Lassen Volcanic Mesa Verde, Denali, Mount Rainier, Olympic, Rocky Mountain, SequoiaKings Canyon, Yellowstone, or Yosemite National Parks, unless a permit for the sale thereof has first been secured from the appropriate Regional Director.

(1) In granting or refusing applications for permits as herein provided, the Regional Directors shall take into consideration the character of the neighborhood, the availability of other liquor-dispensing facilities, the local laws governing the sale of liquor, and any other local factors which have a relationship to the privilege requested.

(2) A fee will be charged for the issuance of such a permit, corresponding to that charged for the exercise of similar privileges outside the park area boundaries by the State government, or appropriate political subdivision thereof within whose exterior boundaries the place covered by the permit is situated.

(3) The applicant or permittee may appeal to the Director from any final action of the appropriate Regional Director refusing, conditioning or revoking the permit. Such an appeal shall be filed, in writing, within 20 days after receipt of notice by the applicant or permittee of the action appealed from. Any final decision of the Director may be appealed to the Secretary of the Interior within 15 days after receipt of notice by the applicant or permittee of the Director's decision.

(4) The permit for sale of intoxicating liquors shall contain such general and special conditions as the Regional Director may deem reasonably necessary to insure safe and orderly management of the park area.

(5) The permittee shall comply with all State and county laws and regulations, other than fee and license requirements, which would be applicable to the premises and to the sale and dispensing of intoxicating beverages if the privately owned lands were not subject

(a) The commercial transportation of passengers by motor vehicles except as authorized under a contract or permit from the Secretary or his authorized representative is prohibited in Crater Lake (prohibition is limited to sightseeing tours on the rim drive), Glacier (prohibition does not apply to nonscheduled tours on portions of the park road as defined in §7.3 of this chapter), Grand Canyon (prohibition does not apply to the north rim or to nonscheduled tours as defined in §7.4 of this chapter), Grand Teton (prohibition does not apply to those portions of Highways Nos. 26, 89, 187, and 287 commencing at the south boundary of the park and running in a general northerly direction to the east and north boundaries of the park), Mesa Verde (prohibition does not apply to transportation between points within the park and outside points), Denali National Park and Preserve (prohibition does not apply to that portion of the Denali Park road between the Highway 3 junction and the Denali Park Railroad Depot), Sequoia-Kings Canyon, Yellowstone (prohibition does not apply to nonscheduled tours as defined in §7.13 of this chapter, nor to that portion of U.S. Highway 191 traversing the northwest corner of the park) and Yosemite National Parks. The following principles will govern the interpretation and enforcement of the section:

(1) Transportation is commercial if it is operated primarily as a business activity or for profit of the operator, or if any person or organization may receive a profit, commission, fee, brokerage or

other compensation for organizing, advertising, promoting, soliciting or selling the trip or tour of which such transportation is a part.

(2) Transportation is commercial if payment therefor is made directly or indirectly to the operator: Provided, That bona fide sharing of actual expenses will not be deemed a payment.

(3) Transportation by a motor vehicle licensed as a commercial vehicle, or of commercial type, will be presumed to be commercial unless otherwise established to the satisfaction of the Superintendent or his authorized representative.

(4) Transportation will not be deemed commercial for the sole reason that the motor vehicle is chartered or rented in good faith to the operator, by the owner, for general use at a charge based upon time or mileage or both. Nothing in this section is intended to prohibit the operation of pleasure type automobiles rented without a driver on the normal terms from the owner.

(5) Subject to the provision of paragraph (a)(1) of this section, transportation is not commercial if it is a part of a trip or tour initiated, organized, and directed by an established bona fide school or college, institution, society or other organization, as a nonprofit activity of such organization, and if all passengers are students, faculty, members, or employees of such organization, or otherwise connected therewith, provided that credentials are presented at the park entrance from the head of such institution or organization indicating the trip is in accordance with the provisions stipulated herein. Clubs or associations having as a principal purpose the arranging of tours, trips, or transportation for their members will not qualify for admission into the above-named parks under the provision of this paragraph.

(6) As used in this section, "owner" means the person or organization having legal title, or all the incidents of ownership other than legal title, of a motor vehicle by which passengers may be transported, and includes a registered owner or a purchaser under a conditional sales contract. "Operator" means the person, organization, or

group that arranges for the transportation, assumes responsibility for financial risk and management, and determines who shall be transported upon what terms, conditions, or charges. The operator may be the owner, but need not be.

(b) Passenger-carrying motor vehicles, otherwise admissible, that are so large as to require special escort in order to proceed safely over park roads, or which in the judgment of the Superintendent are beyond the carrying capacity or safety factor of the roads, will not be permitted in the parks, except that, where they may satisfactorily enter and travel to park headquarters they may be parked there during the period of stay.
