For enhanced safety, the front and second-row seat shoulder belts of the Ford Expedition 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 Chevrolet Tahoe doesn’t offer pretensioners for its second-row seat belts.
With its standard Co-Pilot 360 Assist+, the Ford Expedition is better at preventing collisions with pedestrians than the Chevrolet Tahoe, according to the Insurance Institute for Highway Safety:

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Ford Expedition achieved a higher rating for its forward collision warning and automatic braking systems than the Chevrolet Tahoe which was rated “Poor” in these critical safety features.
The Expedition has standard Post-Impact Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Tahoe 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.
The Expedition’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 Tahoe doesn’t offer a driver alert monitor.
Both the Expedition and the Tahoe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and available all wheel drive.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Ford Expedition is safer than the Chevrolet Tahoe:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Expedition is .4% to 2.6% less likely to roll over than the Tahoe.
