Ch. 6 · Hazardous Areas

At night, when unavoidably stopping or parking on an expressway, it is sufficient to turn on your hazard lights, parking lights, or tail lights, and there is no need to place a warning triangle.

[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.

Correct. Expressways are high-speed zones, so you need every warning measure available to keep others safe.
