General Knowledge Practice Question 54

RequiredGeneral Knowledge · Question 54

On a divided highway, the rear-most reflective triangle should be placed:

• A10 feet behind the vehicle
• B100 feet behind the vehicle
• C200 feet behind the vehicle
• D500 feet behind

Correct answer: C. 200 feet behind the vehicle

Why: On a divided or one-way road, place triangles 10 feet, 100 feet, and 200 feet behind the vehicle on the shoulder or in the lane it is in.

How this question fits the General test

FMCSA requires General Knowledge competency under 49 CFR 383.111 because every CDL holder operates a heavy vehicle in mixed traffic where situational judgment, pre-trip discipline, and emergency response routinely separate a safe trip from a fatal one.

Study technique for this topic
