Beginning on January 1, 2021, and except as provided in §390.401(b) of this section, a motor carrier may transport passengers in a leased or interchanged commercial motor vehicle only under the following conditions:

(a) In general—

(1) Lease or agreement required. There shall be in effect either:

(i) A lease granting the use of the passenger-carrying commercial motor vehicle and meeting the conditions of paragraphs (b) and (c) of this section. The provisions of the lease shall be adhered to and performed by the lessee; or

(ii) An agreement meeting the conditions of paragraphs (b) and (c) of this section and governing the interchange of passenger-carrying commercial motor vehicles between motor carriers of passengers conducting service on a route or series of routes. The provisions of the interchange agreement shall be adhered to and performed by the lessee.

(2) Exception. When an event occurs (e.g., a crash, the vehicle is disabled) that requires a motor carrier of passengers immediately to obtain a replacement vehicle from another motor carrier of passengers, the two carriers may postpone the writing of the lease or written agreement for the replacement vehicle for up to 48 hours after the time the lessee takes exclusive possession and control of the replacement vehicle. However, during that 48-hour period, until the lease or agreement is written and provided to the driver, the driver must carry, and produce upon demand of an enforcement official, a document signed and dated by the lessee's driver or available company official stating: “[Carrier A, USDOT number, telephone number] has leased this vehicle to [Carrier B, USDOT number, telephone number] pursuant to 49 CFR 390.403(a)(2).”

(b) Contents of the lease. The lease or interchange agreement required by paragraph (a) of this section shall contain:

The name of the vehicle manufacturer, the year of manufacture, and at least the last 6 digits of the Vehicle Identification Number (VIN) of each passenger-carrying commercial motor vehicle transferred between motor carriers pursuant to the lease or interchange agreement.

(2) Parties. The legal name, USDOT number, and telephone number of the motor carrier providing passenger transportation in a commercial motor vehicle (lessee) and the legal name, USDOT number, and telephone number of the motor carrier providing the equipment (lessor), and signatures of both parties or their authorized representatives.

(3) Specific duration. The time and date when, and the location where, the lease or interchange agreement begins and ends.

(4) Exclusive possession and responsibilities.

(i) A clear statement that the motor carrier obtaining the passenger-carrying commercial motor vehicle (the lessee) has exclusive possession, control, and use of the passenger-carrying commercial motor vehicle for the duration of the agreement, and assumes complete responsibility for operation of the vehicle and compliance with all applicable Federal regulations for the duration of the agreement.

(ii) In the event of a sublease between motor carriers, all of the requirements of this section shall apply to a sublease.
