Such investigations will be conducted in cooperation with the designated authorities of the state or local jurisdiction in which the accident occurred.
- (b) **Authority to examine or test.** Pursuant to [§ 831.9](/cfr/49/831.9.md) of this part, a credentialed employee of the NTSB is authorized to examine or test any item, including any vehicle, part of a vehicle, equipment, or contents of any vehicle or equipment involved in an accident subject to the NTSB's authority. Examination or testing will be conducted—
  - (1) To the extent practicable, so as to not interfere with or obstruct the transportation services provided by the owner or operator of a vehicle or equipment; and
  - (2) In a manner that preserves evidence relating to the transportation accident, in cooperation with the owner or operator of the vehicle or equipment, and consistent with the needs of the investigation.
- (c) Any Federal, state, or local agency that conducts an investigation of the same highway accident the NTSB is investigating shall provide the results of its investigation to the NTSB.
