Placarded vehicles should not be parked within _____ feet of the traveled portion of any roadway.

• A. 2
• B. 4
• C. 5
• D. 10

Answer: (C)

Placarded vehicles carry hazardous materials, so there must be a safety buffer between the parked vehicle and the traffic lane. Keeping at least five feet from the edge of the traveled portion reduces the risk of a passing vehicle striking the rig or dislodging spilled material, and it also provides space for emergency responders and safe access in case of an incident. Closer gaps (only a couple of feet) offer less margin for error and greater danger, while a much larger gap isn’t the required minimum here. Five feet is the balance that minimizes risk while remaining practical for parking near a roadway.
