Final answer:
The proper position of the brake handle on an SMEE-type subway car when operating normally over the road is the RELEASED position.
Step-by-step explanation:
The PROPER position of the brake handle on an SMEE-type subway car when operating normally over the road is in the RELEASED position. This means that the handle should be in a position where it is not engaged and the brakes are not engaged. When the brake handle is in the RELEASED position, the subway car is free to move.
