Just two years after the launch of the GMT T1XX Chevrolet Silverado and GMC Sierra pickup trucks, GMC is stirring the pot with useful new features designed to relieve some of the stress associated with towing a trailer.

If you see a vehicle in this red hash zone, it is best to wait for it to pass or descend out of this danger zone before changing lanes. The various bed, tailgate and side mirror cameras used to assemble the 360 degree top view also inform this system of the length of the trailer. The driver does not need to measure and enter information to activate this system.
These same cameras closely monitor the proximity of the front corners of the trailer to the rear bumper of the truck and emit an alert (and / or vibrate the safety alert seat) to alert the driver, who must then act. The system will not apply the brakes to avoid a jack knife impact.
