Phillips says instructors work hard to teach new truck drivers about safety.

She hopes a new law will help lower the number of accidents involving commercial vehicles.

"In February of 2020, they will have to go through an approved training provider that will very likely improve a lot of the safety issues we are currently seeing," said Phillips.
