a) to illuminate the working area for the operator.
b) to signal that the vehicle is in transit.
c) to provide a road side warning.

Explanation:

Identify the primary purpose of emergency beacons

Rotating beacons and emergency lights on tow trucks (carriers or wreckers) are designed to warn other motorists of a hazard.

Analyze the given options

• Option A (illuminating the work area) is the function of work lights or floodlights, not warning beacons.
• Option B (signaling transit) is handled by standard driving lights and turn signals.
• Option C (providing a roadside warning) directly matches the safety purpose of high-visibility amber or emergency beacons to alert oncoming traffic.
• Option D (night-time repairs) is also the role of dedicated work lamps.

Select the correct option

Option C is the most accurate description of the primary safety function.

Answer:

• (A) To illuminate the working area for the operator.
• (B) To signal that the vehicle is in transit.
• (C) To provide a ROAD SIDE WARNING. (Correct answer)
