Our company is having a fleet of freight trucks designed with our
company colors, logo, slogan, bullet points on services offered, and
one large photo. I need research on effective placement of different
design elements on branded freight trucks. Design elements include
company logo, text copy, photos, phone number, etc. Trucks will all be
in the US.

Basically I need information on where on a freight truck is best to
place each of the above elements. Looking for marketing and design
research on visibility, readability, etc.

Example: Text on the back of a truck will be read more often because
motorists don't have to take their eyes off traffic to read it.
