Sec.  390.23  Relief from regulations.

    (a) Parts 390 through 399 of this chapter shall not apply to any 
motor carrier or driver operating a commercial motor vehicle to provide 
emergency relief during an emergency, subject to the following time 
limits:
    (1) Regional emergencies. (i) The exemption provided by paragraph 
(a)(1) of this section is effective only when:
    (A) An emergency has been declared by the President of the United 
States, the Governor of a State, or their authorized representatives 
having authority to declare emergencies; or
    (B) The FMCSA Field Administrator has declared that a regional 
emergency exists which justifies an exemption from parts 390 through 399 
of this chapter.
    (ii) Except as provided in Sec.  390.25, this exemption shall not 
exceed the duration of the motor carrier's or driver's direct assistance 
in providing emergency relief, or 30 days from the date of the initial 
declaration of the emergency or the exemption from the regulations by 
the FMCSA Field Administrator, whichever is less.
    (2) Local emergencies. (i) The exemption provided by paragraph 
(a)(2) of this section is effective only when:
    (A) An emergency has been declared by a Federal, State or local 
government official having authority to declare an emergency; or
    (B) The FMCSA Field Administrator has declared that a local 
emergency exists which justifies an exemption from parts 390 through 399 
of this chapter.
    (ii) This exemption shall not exceed the duration of the motor 
carrier's or driver's direct assistance in providing emergency relief, 
or 5 days from the date of the initial declaration of the emergency or 
the exemption from the regulations by the FMCSA Field Administrator, 
whichever is less.
    (3) Tow trucks responding to emergencies. (i) The exemption provided 
by paragraph (a)(3) of this section is effective only when a request has 
been made by a Federal, State or local police officer for tow trucks to 
move wrecked or disabled motor vehicles.
    (ii) This exemption shall not exceed the length of the motor 
carrier's or driver's direct assistance in providing emergency relief, 
or 24 hours from the time of the initial request for assistance by the 
Federal, State or local police officer, whichever is less.
    (b) Upon termination of direct assistance to the regional or local 
emergency relief effort, the motor carrier or driver is subject to the 
requirements of parts 390 through 399 of this chapter, with the 
following exception: A driver may return empty to the motor carrier's 
terminal or the driver's normal work reporting location without 
complying with parts 390 through 399 of this chapter. However, a driver 
who informs the motor carrier that he or she needs immediate rest must 
be permitted at least 10 consecutive hours off duty before the driver is 
required to return to such terminal or location. Having returned to the 
terminal or other location, the driver must be relieved of all duty and 
responsibilities. Direct assistance terminates when a driver or 
commercial motor vehicle is used in interstate commerce to transport 
cargo not destined for the emergency relief effort, or when the motor 
carrier dispatches such driver or commercial motor vehicle to another 
location to begin operations in commerce.
    (c) When the driver has been relieved of all duty and 
responsibilities upon termination of direct assistance to a regional or 
local emergency relief effort, no motor carrier shall permit or require 
any driver used by it to drive nor shall any such driver drive in 
commerce until:
    (1) The driver has met the requirements of Sec.  Sec.  395.3(a) and 
395.5(a) of this chapter; and
    (2) The driver has had at least 34 consecutive hours off-duty when:

    (i) The driver has been on duty for more than 60 hours in any 7 
consecutive days at the time the driver is relieved of all duty if the 
employing motor carrier does not operate every day in the week, or
    (ii) The driver has been on duty for more than 70 hours in any 8 
consecutive days at the time the driver is relieved of all duty if the 
employing motor carrier operates every day in the week.
