通常须收到核实的阴性结果后才能安排上岗Normally receive the verified negative result before safety-sensitive work
- 具体要求What the rule requires
- 司机首次为雇主执行安全敏感工作前，通常须完成药物检测，雇主收到 MRO 或 C/TPA 提供的核实阴性结果后才能安排工作。过去接受过检测，不一定符合豁免；采用本条(b)的例外，须满足既往项目参与和记录核实条件。Before the first safety-sensitive work for an employer, a controlled-substances test is normally required and the employer must receive a verified negative result from the MRO or C/TPA. Prior testing is not an automatic exemption; the paragraph (b) exception requires the specified participation history and verification.
(a) (a) Prior to the first time a driver performs safety-sensitive functions for an employer, the driver shall undergo testing for controlled substances as a condition prior to being used, unless the employer uses the exception in paragraph (b) of this section. No employer shall allow a driver, who the employer intends to hire or use, to perform safety-sensitive functions unless the employer has received a controlled substances test result from the MRO or C/TPA indicating a verified negative test result for that driver.
(b) (b) An employer is not required to administer a controlled substances test required by paragraph (a) of this section if:
(b)(1) (1) The driver has participated in a controlled substances testing program that meets the requirements of this part within the previous 30 days; and
(b)(2) (2) While participating in that program, either:
(b)(2)(i) (i) Was tested for controlled substances within the past 6 months (from the date of application with the employer), or
(b)(2)(ii) (ii) Participated in the random controlled substances testing program for the previous 12 months (from the date of application with the employer); and
(b)(3) (3) The employer ensures that no prior employer of the driver of whom the employer has knowledge has records of a violation of this part or the controlled substances use rule of another DOT agency within the previous six months.
(c)(1) (c)(1) An employer who exercises the exception in paragraph (b) of this section shall contact the controlled substances testing program(s) in which the driver participates or participated and shall obtain and retain from the testing program(s) the following information:

事故后的酒精与药物检测§ 382.303 Post-accident testing.§ 382.303 Post-accident testing.事故后的酒精与药物检测
适用于 Part 382 覆盖、需要 CDL 的商业驾驶工作。是否豁免，不能仅凭业务在州内还是跨州判断。本文概述办理要求，不判定个人检测结果或回岗资格。For CDL-required commercial driving covered by Part 382; intrastate versus interstate operation alone does not establish an exemption. This is a process overview, not a decision on an individual test result or return-to-duty eligibility.
事故后是否检测及何时检测，须按触发条件判断Check the accident trigger before applying testing deadlines
- 具体要求What the rule requires
- 死亡事故和特定非死亡事故适用不同的检测触发条件。非死亡事故中，有人因伤立即在事故现场以外接受医疗处理，或有车辆因事故损坏而无法按通常方式驶离，须由拖车或其他机动车运离现场时，还要看司机是否在规定时段内收到由该事故引起的行车违法传票。需要酒精检测而两小时内未完成的，应记录原因；八小时后须停止尝试并留存记录。需要药物检测而 32 小时内未完成的，也须停止尝试并留存记录。不得为等候检测延误必要急救。Fatal and qualifying nonfatal accidents have different triggers. For nonfatal accidents, check for bodily injury with immediate medical treatment away from the scene or disabling vehicle damage requiring transport from the scene, together with a moving-violation citation arising from the accident within the applicable window. If required alcohol testing is not completed within two hours, record why; stop attempts after eight hours and document. Stop required drug-test attempts after 32 hours and document. Do not delay necessary medical care.
- 条件与例外Conditions and exceptions
- 非死亡事故的传票窗口：酒精检测为事故后 8 小时内，药物检测为 32 小时内。不是每次小碰擦都自动触发联邦事故后检测。For nonfatal accidents, the citation window is eight hours for alcohol testing and 32 hours for controlled-substances testing. Not every minor collision automatically triggers federal post-accident testing.
(a) (a) As soon as practicable following an occurrence involving a commercial motor vehicle operating on a public road in commerce, each employer shall test for alcohol for each of its surviving drivers:
(a)(1) (1) Who was performing safety-sensitive functions with respect to the vehicle, if the accident involved the loss of human life; or
(a)(2) (2) Who receives a citation within 8 hours of the occurrence under State or local law for a moving traffic violation arising from the accident, if the accident involved:
(a)(2)(i) (i) Bodily injury to any person who, as a result of the injury, immediately receives medical treatment away from the scene of the accident; or
(a)(2)(ii) (ii) One or more motor vehicles incurring disabling damage as a result of the accident, requiring the motor vehicle to be transported away from the scene by a tow truck or other motor vehicle.
(b) (b) As soon as practicable following an occurrence involving a commercial motor vehicle operating on a public road in commerce, each employer shall test for controlled substances for each of its surviving drivers:
(b)(1) (1) Who was performing safety-sensitive functions with respect to the vehicle, if the accident involved the loss of human life; or
(b)(2) (2) Who receives a citation within thirty-two hours of the occurrence under State or local law for a moving traffic violation arising from the accident, if the accident involved:
(b)(2)(i) (i) Bodily injury to any person who, as a result of the injury, immediately receives medical treatment away from the scene of the accident; or
(b)(2)(ii) (ii) One or more motor vehicles incurring disabling damage as a result of the accident, requiring the motor vehicle to be transported away from the scene by a tow truck or other motor vehicle.
(d)(1) (d)(1) Alcohol tests. If a test required by this section is not administered within two hours following the accident, the employer shall prepare and maintain on file a record stating the reasons the test was not promptly administered. If a test required by this section is not administered within eight hours following the accident, the employer shall cease attempts to administer an alcohol test and shall prepare and maintain the same record. Records shall be submitted to the FMCSA upon request.
(d)(2) (2) Controlled substance tests. If a test required by this section is not administered within 32 hours following the accident, the employer shall cease attempts to administer a controlled substances test, and prepare and maintain on file a record stating the reasons the test was not promptly administered. Records shall be submitted to the FMCSA upon request.
(e) (e) A driver who is subject to post-accident testing shall remain readily available for such testing or may be deemed by the employer to have refused to submit to testing. Nothing in this section shall be construed to require the delay of necessary medical attention for injured people following an accident or to prohibit a driver from leaving the scene of an accident for the period necessary to obtain assistance in responding to the accident, or to obtain necessary emergency medical care.

Applicability, intrastate rules, qualification exceptions, exemptions, restrictions, and individual medical-certification periods still depend on the operation and current official sources.

- 具体要求What the rule requires
- 对受 Part 382 药物、酒精测试规则约束、将执行安全敏感工作的司机，雇主须取得司机的特定同意，并在上岗前完成完整查询；在职期间至少每年再查询一次。年度查询可从有限查询开始，其结果只显示有无信息，不显示具体内容或完整禁驾结论。若显示存在信息，雇主须在 24 小时内完成完整查询；逾期未完成的，不得继续安排安全敏感工作，直至完整结果确认没有禁令。For a driver subject to Part 382 testing who will perform safety-sensitive work, the employer must first conduct a full pre-employment query with the driver's specific consent and must query at least annually thereafter. A limited annual query only indicates whether information exists; it does not disclose the information or establish the full prohibition status. If information exists, the employer must conduct a full query within 24 hours or stop the driver from safety-sensitive work until the full result confirms no prohibition.
(a)(2) (2) The employer must conduct a full query under this section, which releases information in the Clearinghouse to an employer and requires that the individual driver give specific consent.
(b) (b) Annual query required. (1) Employers must conduct a query of the Clearinghouse at least once per year for information for all employees subject to controlled substance and alcohol testing under this part to determine whether information exists in the Clearinghouse about those employees.

- 首次安排该司机执行安全敏感工作前须进行 Clearinghouse 全量查询；在职司机至少每年查询一次。符合条件的年度有限查询若显示有记录，应在 24 小时内完成全量查询；未及时完成时，不得继续安排安全敏感工作，直到全量查询确认没有禁止上岗的记录。A full Clearinghouse query is required before permitting the driver’s first safety-sensitive work, with a query at least annually afterward. If a qualifying annual limited query indicates a record, complete the full query within 24 hours. If that deadline is missed, do not allow safety-sensitive work until a full query confirms no prohibiting record.
(a) (a) Pre-employment query required. (1) Employers must not employ a driver subject to controlled substances and alcohol testing under this part to perform a safety-sensitive function without first conducting a pre-employment query of the Clearinghouse to obtain information about whether the driver has a verified positive, adulterated, or substituted controlled substances test result; has an alcohol confirmation test with a concentration of 0.04 or higher; has refused to submit to a test in violation of § 382.211; or that an employer has reported actual knowledge, as defined at § 382.107, that the driver used alcohol on duty in violation of § 382.205, used alcohol before duty in violation of § 382.207, used alcohol following an accident in violation of § 382.209, or used a controlled substance, in violation of § 382.213.

The limited query will tell the employer whether there is information about the individual driver in the Clearinghouse, but will not release that information to the employer. The individual driver may give consent to conduct limited queries that is effective for more than one year.
(b)(3) (3) If the limited query shows that information exists in the Clearinghouse about the individual driver, the employer must conduct a full query, in accordance with paragraph (a)(2) of this section, within 24 hours of conducting the limited query. If the employer fails to conduct a full query within 24 hours, the employer must not allow the driver to continue to perform any safety-sensitive function until the employer conducts the full query and the results confirm that the driver's Clearinghouse record contains no prohibitions as defined in paragraph (d) of this section.
(d) (d) Prohibition.
