Multiple choice — select the best answer

AThe emergency (supply) glad hand, which charges the dolly's air tanks and releases the spring brakes when connected
BConverter dollies do not have spring brakes; they rely entirely on the combination's service brake pressure
CThe service glad hand only, since dolly spring brakes are modulated through the foot pedal
DA dedicated third glad hand labeled 'DOLLY' found only on newer converter dolly models

✓ Correct answer: A. The emergency (supply) glad hand, which charges the dolly's air tanks and releases the spring brakes when connected Per the CDL manual, the emergency (supply) line glad hand charges the converter dolly's air reservoir and releases the spring parking brakes; disconnecting the supply line causes the dolly's spring brakes to apply automatically.
