The Terrain’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Bronco and is not available with Base.
For better protection of the passenger compartment, the Terrain uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Bronco uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the Terrain and the Bronco have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the GMC Terrain is safer than the Ford Bronco:

The Insurance Institute for Highway Safety rates the general design of front seat head restraints for their ability to protect front seat occupants from whiplash injuries. The IIHS also performs a dynamic test on those seats with “good” or “acceptable” geometry. In these ratings, the Terrain is safer than the Bronco:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Terrain, with its four-star roll-over rating, is 7.1% to 9.2% less likely to roll over than the Bronco, which received a three-star rating.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Terrain the rating of “Top Safety Pick” for 2017, a rating granted to only 231 vehicles tested by the IIHS. The Bronco was not even a “Top Safety Pick” for 2016.
