A truck driving school instructor said:

Hearing is only one of the six senses a driver needs.
A driver has to be able to see, feel, even smell your
cargo, your brakes, engine issues.

The deaf student I had is hyper-aware of everything
that’s going on because she doesn’t have the distraction.

This deaf student drives every day in a car;
these car-driving skills can be transferred
to driving a truck.

I don’t see deafness as a disadvantage in truck
