(a) General. Whenever a motor vehicle of a type referred to in § 167.2 (relating to scope and application) is disabled or stopped upon a roadway or shoulder, the driver of the stopped or disabled vehicle shall immediately flash the two front and two rear signal lamps simultaneously as a vehicular traffic hazard warning and continue the flashing until he places the warning devices of the type required under § 167.3 (relating to types of warning devices) in use on the highway. The flashing signals shall be used during the time the warning devices are picked up for storage before movement of the vehicle. The flashing lights may be used at other times while a vehicle is stopped in addition to, but not in lieu of, the warning devices of the type required under § 167.3.
(b) Placement of warning devices. Requirements for placement shall be as follows:
(1) General rule. Except, as provided in paragraph (2), whenever a vehicle is stopped or disabled upon the roadway or the shoulder for any cause other than necessary traffic stops, the driver shall as soon as possible, but in any event within 10 minutes, place the warning devices of the type required under § 167.3 in the following manner:
(i) One at the traffic side of the stopped or disabled vehicle, within 10 feet of the front or rear of the vehicle.
(ii) One at a distance of approximately 100 feet from the stopped or disabled vehicle in the center of the traffic lane or shoulder occupied by the vehicle and in the direction toward traffic approaching in that lane.
(iii) One at a distance of approximately 100 feet from the stopped or disabled vehicle in the center of the traffic lane or shoulder occupied by the vehicle and in the direction in which traffic in that lane is moving.
(2) Special rules. Special rules for placement shall be as follows:
(i) Fusees. The driver of a vehicle equipped with liquid-burning emergency flares shall first place a fusee at the location specified in paragraph (1)(iii).
(ii) Daylight hours. Except as provided in subparagraph (iii) during the period lighted lamps are not required, three emergency triangles shall be placed as specified in paragraph (1) or two red flags as specified in paragraph (1)(i)—(iii) and within a time of 10 minutes.

The placement of warning devices may not be required within the business or residential district of a municipality, except during the time lighted lamps are required by 75 Pa.C.S. § 4302 (relating to period for requiring lighted lamps) and when street or highway lighting is insufficient to make a vehicle clearly discernible at a distance of 500 feet to persons on the highway.
(iv) Hills, curves and obstructions. If a motor vehicle is stopped or disabled within 500 feet of a curve, crest of a hill or other obstruction to view, the driver shall place the warning signal required by § 167.3 in the direction of the obstruction to view at a distance of 100 feet to 500 feet from the stopped or disabled vehicle so as to afford ample warning to other users of the highway.

If a motor vehicle is stopped or disabled upon a roadway or shoulder of a divided or one-way highway, the driver shall place the warning devices required by § 167.3, one at a distance of 200 feet and one at a distance of 100 feet in a direction toward approaching traffic in the center of the lane or shoulder occupied by the vehicle, and one at the traffic side of the vehicle within 10 feet of the vehicle.
