In particular, a combination of seven cameras help drivers navigate with a trailer. The “trailer reverse guidance,” which uses three high-resolution cameras, allows the driver to check out a wider range of angles in the blind spot of the trailer, monitoring for obstacles as the truck backs up. “The system presents a color-coded bird’s-eye representation of truck and trailer on the console touch screen,” according to Ford. “Yellow or red means the trailer angle is too tight and there is a risk of jackknifing.” The system, Shaw said, is the only one of its kind available for a trailer.
