Railroad & Special第 42 / 80 题

A driver approaching a railroad crossing should turn off or reduce:

a.The parking brake
b.Radios, fans, and other noise so the driver can listen for a train
c.The mirrors
d.The stop arm

解析

Before a crossing the driver should silence or reduce noise from the radio, fans, and heaters and quiet the students so a train's horn or bell can be heard. Opening the door and window further improves hearing. Listening is a key part of the stop-look-listen routine.
