The term 'THEY'RE DEPRESSED BY DRIVERS' can be solved by the crossword clue 'BRAKES' (6 letters). BRAKES are a safety feature on vehicles that allow drivers to slow down or stop. They are typically operated by pressing down on a pedal with the foot. When BRAKES are depressed, they cause friction between two surfaces, which creates a slowing or stopping force. This force is what allows drivers to safely control their speed and come to a complete stop.
