For enhanced safety, the front and rear seat shoulder belts of the Ford Bronco have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Terrain doesn’t offer pretensioners for its rear seat belts.
The Bronco has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Terrain doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Bronco. But it costs extra on the Terrain.
The Bronco Big Bend/Outer Banks/Badlands/Stroppe/Raptor/Heritage’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Terrain doesn’t offer a driver alert monitor.
Both the Bronco and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Ford Bronco weighs 624 to 2314 pounds more than the GMC Terrain. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Ford Bronco is safer than the GMC Terrain:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Ford Bronco 4-Door is much safer than the Terrain:
