经营注册与税费Registration & taxes
先确定公司做什么业务、车辆在哪里运营，再核对需要的联邦和州级记录。不要把一个号码或许可当成全部手续。Identify the business activity and where vehicles operate, then check the relevant federal and state records. One number or permit does not represent every filing.
开车队，拿到一个号码只是其中一步。把公司登记资料、允许开展的业务、保险保障和车上的标识分别核对，才能看出还缺哪件事。下面先讲最容易混在一起的三项。Getting a number is one step in starting a carrier. Check company registration, the operations permitted, financial responsibility and vehicle markings separately. These three common requirements help you see what each record actually does.
本节侧重受联邦规则约束的承运人登记、载货运输财务责任及车辆标识。州内业务、危险品、租赁和其他特殊运营可能适用不同要求；MC 经营许可、加州 MCP、UCR、IRP、IFTA 与税务仍须分别核对。This section focuses on federal carrier reporting, financial responsibility for property carriage and vehicle markings. Intrastate, hazardous-material, leased and other special operations can have different requirements. Operating authority, California MCP, UCR, IRP, IFTA and tax filings need separate review.
先弄清这几条要求Start with these requirements
两年更新按指定年份和月份，不是自己记一个周年日Biennial updates follow an assigned year and month
- 具体要求What the rule requires
- 受本条约束的承运人要在运营前登记，之后按规定做双年度更新。月份看 USDOT 最后一位数字，年份看倒数第二位的奇偶；不是“上次提交后再等整整两年”。资料没变，也要核对本轮更新。完成 MCS-150 不等于 MC 经营许可、保险或州级手续已经齐全。 Motus 过渡期有临时安排：截至 2026 年 10 月 12 日查阅，FMCSA 对 2026 年 6 月 1 日或以后到期的双年度更新给予额外时间，暂缓相关执法，并暂不因未完成该项更新而停用 USDOT。办理前请核对官方后续公告和本主体的实际登记状态。A carrier covered by this section reports before operating and then follows its biennial schedule. The final USDOT digit sets the month; the next-to-last digit sets odd or even years. Do not simply wait two years after the last submission. Check the scheduled update even if information is unchanged. An MCS-150 update does not complete operating-authority, insurance or state requirements. A temporary Motus transition arrangement applies: as checked on October 12, 2026, FMCSA gives additional time for biennial updates due on or after June 1, 2026, temporarily suspending related enforcement and USDOT inactivation for failure to complete that update. Check subsequent official notices and the entity’s actual registration status before acting.
- 条件与例外Conditions and exceptions
- 临时安排仅针对公告涵盖的 2026 年 6 月 1 日或以后到期的双年度更新。公告未给统一结束日；它不取消一般登记周期、其他登记、经营许可或保险义务，也未宣布自动恢复已停用的 USDOT 状态。The temporary arrangement covers biennial updates due on or after June 1, 2026, as described in the notice. No fixed end date is stated. It does not remove the ordinary reporting schedule or other registration, operating-authority or insurance duties, and does not announce automatic restoration of an already inactive USDOT status.
(b)(1) (1) Before it begins operations; and
(b)(2) (2) Every 24 months, according to the following schedule:
(b)(3) (3) If the next-to-last digit of its USDOT Number is odd, the motor carrier or intermodal equipment provider shall file its update in every odd-numbered calendar year. If the next-to-last digit of the USDOT Number is even, the motor carrier or intermodal equipment provider shall file its update in every even-numbered calendar year.
原文后接月份表：末位 1–9 分别对应 1–9 月，末位 0 对应 10 月，均为当月最后一天。The source table assigns final digits 1–9 to January–September and 0 to October, with filing due by the last day of the month.
要有正在生效的保障，不能只看“已经买过保险”Required coverage must actually be in effect
- 具体要求What the rule requires
- 如果你的运营受本分部约束，要求的是达到适用最低标准、而且正在生效的财务保障。先核对承运业务、货物类型、车辆情况，再对照 §387.9 的额度表；不要把别人公司的额度照搬过来。续保时让保险服务方确认生效时间和所需申报，旧的保险证明不能说明今天仍有保障。If the operation falls under this subpart, the applicable minimum financial responsibility must be in effect. Match the operation, cargo and vehicle to the amounts in §387.9 instead of copying another carrier. At renewal, confirm effective dates and required filings with the insurance provider. An old certificate does not establish coverage today.
(a) (a) No motor carrier shall operate a motor vehicle until the motor carrier has obtained and has in effect the minimum levels of financial responsibility as set forth in § 387.9 of this subpart.
车辆两侧的承运人名称和 USDOT，要能与登记资料对上The operating carrier and USDOT markings must match the records
- 具体要求What the rule requires
- 受本条约束的动力车辆，应显示实际运营承运人的登记名称或一个商号，以及带有“USDOT”字样的号码。两侧都要有，颜色要醒目，白天车辆静止时应能在 50 英尺外读清。租车、挂靠或车身还有别人的名称时，要继续查相关小款；不是只贴一个好看的公司标志就够。A covered power unit must show the operating carrier’s registered legal or single trade name and number preceded by “USDOT.” Markings go on both sides, contrast with the background and remain readable from 50 feet in daylight while stationary. Rental arrangements or another name on the vehicle require checking the related provisions. A company logo alone is not enough.
(b) (b) Nature of marking. The marking must display the following information:
(b)(1) (1) The legal name or a single trade name of the motor carrier operating the self-propelled CMV, as listed on the motor carrier identification report (Form MCS-150) and submitted in accordance with § 390.19T.
(b)(2) (2) The identification number issued by FMCSA to the motor carrier or intermodal equipment provider, preceded by the letters “USDOT.”
教学例子WORKED EXAMPLE
公司资料已更新，明天就能接单了吗？The company record is updated. Can you haul tomorrow?
教学情境：一家小车队刚更新了登记资料，正准备安排一辆车出车。负责人不能只凭“提交成功”四个字作决定。Example: a small carrier has just updated its registration and wants to dispatch a truck. A submission confirmation alone cannot answer whether the trip may proceed.
先问：完成的是哪一项？Identify what was completed
如果只是 MCS-150 更新，就把它记为公司资料更新，不把它当成经营许可或保险凭证。Record an MCS-150 update as a carrier-information update, not an operating permit or proof of insurance.
再核对：业务和保障Check operations and coverage
按这趟货的业务范围，查看所需经营许可与保险是否有效；需要加州 MCP 等手续的，另外查官方状态。For this load, check the required authority and effective financial responsibility. Review California MCP and other applicable state requirements separately.
最后对上：公司、车与文件Match the carrier, truck and documents
确认车上标识、实际运营承运人与文件相符。发现名称、时间或状态对不上，先请负责登记或保险的人查清。Compare the vehicle markings and paperwork with the actual operating carrier. Resolve mismatched names, dates or status with the responsible registration or insurance contact.
这三步帮助你找出问题，不是完整开业清单；其他注册和税务事项仍沿用下方现有指南。These steps locate gaps; they are not a complete startup checklist. Use the existing guides below for other registration and tax requirements.
实际工作中，最容易弄错的地方Common mistakes in day-to-day work
USDOT、MC、MCP 不是同一张许可证USDOT, operating authority and MCP are different
登记识别、开展某类业务的许可、加州承运许可分别处理不同问题。看到一个号码，不要替另外两项下结论；要按实际业务查对应官方状态。Carrier identification, authority for an operation and California carrier permitting serve different purposes. A number in one system does not establish the others. Check each requirement against the actual operation.
条号末尾的 T 不能随手省掉Keep the T in the citation
这里引用的是 §390.19T、§390.21T。法规中可能同时出现带 T 和不带 T 的版本，不能只看号码相近就当成同一条；查看来源时保留完整条号和版本说明。These excerpts cite §390.19T and §390.21T. Provisions with and without T can coexist with different status notes. Keep the full citation and source version when checking a requirement.

本页原文采用知识库固定留存的版本，版本日期见各全文。本次修订按库内当前版次重新选择 §390.19T、§387.7 和 §390.21T 的节选；版次更新本身不等于法律要求发生变化。2026-10-12 另查阅 FMCSA 的 Motus 临时公告（官方页面更新于 2026-09-10）：https://www.fmcsa.dot.gov/registration/temporary-suspension-biennial-update-requirement 。该公告针对 2026-06-01 或以后到期的双年度更新，未给统一结束日；办理前应查看后续公告。查阅或采集日期不是生效日期。中文为 CTAC 白话说明，不是官方中文译文。The text uses pinned library editions; version dates appear in each full-text reader. This revision reselects passages from the current library editions of §§390.19T, 387.7 and 390.21T; an edition change alone does not establish a change in legal requirements. On October 12, 2026, we also consulted FMCSA’s Motus notice, updated September 10, 2026: https://www.fmcsa.dot.gov/registration/temporary-suspension-biennial-update-requirement . It covers biennial updates due on or after June 1, 2026, and states no fixed end date; check subsequent notices before acting. Consultation or capture dates are not effective dates.
