The small overlap front evaluation consists of a driver-side and a passenger-side component.
If the results of the two evaluations differ, then the combined small overlap rating is equal to the lower rating.
Driver-side
Rating applies to 2025 models
Tested vehicle: 2023 Toyota Prius LE 4-door
The Toyota Prius and Prius Prime were redesigned for the 2023 model year. Beginning with 2025 models, the Prius Prime became known as the Prius Plug-in Hybrid. Driver-side small overlap frontal ratings are assigned by the Institute based on a test of a 2023 Prius conducted by Toyota.

Negative numbers indicate the amount by which the crush stopped short of the seat centerline.
Distance at which headlights provide at least 5 lux illumination:
Low beams
On the straightaway, visibility was fair on the left side of the road and inadequate on the right side. On curves, visibility was good on both right curves and inadequate on both left curves.
The low beams never exceeded glare limits.
High beams
On the straightaway, visibility was fair on both sides of the road. On curves, visibility was good on the gradual right and gradual left curves and fair on the sharp right and sharp left curves.
High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
