Two People, One Idea.

It was the 1970s and Merritt Mosby, a San Francisco/Bay Area truck driver was cited by the California Highway Patrol for using a “WIDE LOAD” sign on his truck that did not meet the state’s regulations. It was then that Merritt and Carita Mosby decided to fabricate their own “WIDE LOAD” signs because trucking signs were not commercially available. In their garage they began to manufacture handmade signs using spray paint and stencils. Soon a San Francisco truck dealership as well as independent truckers heard about their signs and began submitting orders. In 1972, after taking classes in screen printing, and a business start up seminar, the Mosby’s created "Ms. Carita, Inc". The name was derived from a popular trend at that time, using the courtesy title "Ms." in front of a woman’s name. They felt that "Ms. Carita" would be a name truckers would remember…a feminine name in a macho industry.

Two of Merritt and Carita’s three sons worked with their parents learning the screen printing trade in their garage. At the beginning of their careers, Michael and Gordon Mosby ventured out and began working for large companies in the large format and close tolerance label/graphics industries. In 1985, both sons rejoined their parent’s company bringing their added expertise into Ms. Carita. Sales exceeded expectations over the next four years. In 1989, Merritt retired from driving trucks and focused his attention solely on Ms. Carita. In 1994 and 1997, Michael Mosby took over the role of “President” and “CEO” for Ms. Carita.

In 2003, Ms.Carita began a branding campaign for their Transportation Safety Products under the new name SafeTRUCK. In 2006, SafeTRUCK and Ms. Carita became two separate entities. SafeTRUCK’s manufacturing and distribution operation is located in a 15,000 sq foot facility in Nevada. Corporate headquarters for both companies is located in a 20,000 sq foot manufacturing facility in Livermore, California.

Today, Merritt and Carita Mosby are enjoying retirement. Gordon Mosby is Vice President and National Sales Manager for SafeTRUCK. Michael Mosby is Chairman and President/CEO of Ms. Carita and SafeTRUCK.

Right People, Right Ideas.

The proof was in the people and the ideas. Ms. Carita has grown from a spray paint and stencil shop in the family’s garage, to a leader in the manufacturing and distribution of innovative truck safety products as well as the production of custom product identification components, labels, graphic overlays, placards/decals and event graphics.
