Small overlap front: driver-side

Rating applies to 2018-24 models

Tested vehicle: 2020 Chevrolet Traverse High Country 4-door 4wd

The Chevrolet Traverse and Buick Enclave were redesigned for the 2018 model year. They are smaller and lighter than the earlier design and therefore are now classified as midsize SUVs.

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

Despite some intrusion of the door hinge pillar, risk of injuries to the dummy's legs and feet was low.

About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2018-21 models built after December 2018

Tested vehicle: 2021 Chevrolet Traverse 3LT 4-door 4wd

The Chevrolet Traverse and Buick Enclave were redesigned for the 2018 model year. They are smaller and lighter than the earlier design and therefore are now classified as midsize SUVs. Beginning with models built after December 2018, reinforcements were made to the passenger-side A pillar to improve occupant protection in passenger-side small overlap crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Action shot taken during the passenger-side small overlap frontal crash test.

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger's survival space was maintained reasonably well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The passenger’s space was maintained reasonably well, and risk of injuries to the dummy's legs and feet was low.

On the straightaway, visibility was good on both sides of the road. On curves, visibility was good on the gradual left and both right curves and fair on the sharp left curve.

The low beams created some glare.

High beams
On the straightaway, visibility was fair on the right side of the road and inadequate on the left side. On curves, visibility was good on the gradual right curve, fair on the sharp right and gradual left curves, and inadequate on the sharp left curve.
