[True / False · Hard]
Answer: False
Explanation
The Rules of the Road section "2. Lights (6)" clearly states that "at night, when unavoidably stopping or parking on an expressway, in addition to turning on your hazard lights, parking lights, or tail lights, you must place a warning triangle." Both lights and a warning triangle are required.
