进入港口等受控区域的 TWIC 要求§ 101.514 TWIC Requirement.查看运输工人身份凭证 TWIC 在海事受控区域的使用要求。Port operations / Driver qualifications§ 101.514 TWIC Requirement.进入港口等受控区域的 TWIC 要求
TWIC 内容针对联邦海事安保规则下的无人陪同进入安全区域；车辆登记例子限于洛杉矶港项目说明；费用内容是 FMC 对受其监管主体的集装箱滞期、滞箱做法的解释规则。不能直接推广到所有仓库、港口或公路等待费。TWIC concerns unescorted access to secure areas under federal maritime-security rules. The truck-registration example is Los Angeles-specific program guidance. The FMC content interprets container demurrage and detention practices by regulated entities, not every warehouse, port or highway waiting charge.
TWIC 对应的是人员安保准入，不是提柜授权TWIC addresses security access, not authorization to collect cargo
- 具体要求What the rule requires
- 如果需要无人陪同进入这些受监管安全区域，通常先要持有 TWIC；条文本身保留了具体例外。拿到卡并不代表这次货已放行，也不能替代预约、码头身份登记或车辆要求。出发前分别问清：人能否进入、车能否进入、柜能否提走。不能用别人的卡替代自己的身份。A person needing unescorted access to a covered secure area generally needs a TWIC, subject to the stated exceptions. Possessing it does not release cargo or satisfy appointment, terminal-identification and truck requirements. Before departure, separately confirm access for the person, access for the truck and release of the container. Another person’s card does not establish your identity.
(a) (a) All persons requiring unescorted access to secure areas of vessels, facilities, and OCS facilities regulated by parts 104, 105 or 106 of this subchapter must possess a TWIC before such access is granted, except as otherwise noted in this section. A TWIC must be obtained via the procedures established by TSA in 49 CFR part 1572.

海运滞箱费、滞期费是否合理的判断原则§ 545.5 Interpretation of Shipping Act of 1984—Unjust and unreasonable practices with respect to demurrage and detention.这是海运滞箱、滞期收费的判断原则，不是司机等装卸补偿的统一标准。Port operations§ 545.5 Interpretation of Shipping Act of 1984—Unjust and unreasonable practices with respect to demurrage and detention.海运滞箱费、滞期费是否合理的判断原则
TWIC 内容针对联邦海事安保规则下的无人陪同进入安全区域；车辆登记例子限于洛杉矶港项目说明；费用内容是 FMC 对受其监管主体的集装箱滞期、滞箱做法的解释规则。不能直接推广到所有仓库、港口或公路等待费。TWIC concerns unescorted access to secure areas under federal maritime-security rules.

还不了空柜，要保留事实；不是看到收费就只能照付Keep evidence when an empty container cannot be returned
- 具体要求What the rule requires
- FMC 的解释规则会看收费是否还在起“促使尽快流转”的作用。对符合适用范围的空柜滞箱费，如果确实不能还柜、又没有需要另行考虑的情形，收费做法很可能被认定不合理。但这不是“没约到就自动免单”。保存预约限制、拒收通知、联系记录和收费日期，再按收费方的争议流程提出具体理由。The FMC considers whether a charge serves its purpose of encouraging cargo and equipment movement. For covered detention, charges when empty containers cannot be returned are likely unreasonable absent extenuating circumstances. This does not mean an unavailable appointment automatically cancels a bill. Retain appointment restrictions, rejection notices, communications and billed dates, then present specific reasons through the billing party’s dispute process.
(c)(2)(ii) (ii) Empty container return. Absent extenuating circumstances, practices and regulations that provide for imposition of detention when it does not serve its incentivizing purposes, such as when empty containers cannot be returned, are likely to be found unreasonable.

人在系统里，不代表车辆也已登记A registered driver does not mean the truck is registered
- 具体要求What the rule requires
- 洛杉矶港项目说明要求进入海运码头的卡车列入 PDTR。车队应分别核对承运人的港口准入资格、这辆车的登记和准确资料，再确认具体码头本次作业的条件。这里引用的是港口项目说明，不是全国统一法规；长滩港或其他港口应查各自要求，不能凭一次进港成功认定以后都没问题。Los Angeles program guidance requires trucks entering marine terminals to be in PDTR. Check the carrier’s port-access standing and the truck’s accurate registration separately, then confirm the terminal’s requirements for this move. This is port program guidance, not a nationwide regulation. Check Long Beach and other ports individually; one successful gate visit does not establish continuing access.
As part of the Clean Truck Program, all trucks entering marine terminals must be on the Ports Drayage Truck Registry (PDTR). It is important for Licensed Motor Carriers (LMC) to confirm their Concession status and maintain accurate truck data in the PDTR. To obtain access to the PDTR, you will be registered in the PDTR upon completion of your concession agreement processing. As of October 1, 2018, new PDTR registrations of trucks entering new service at the Port of Los Angeles must be model year 2014 or newer.
