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

The low beams created some glare.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and on both left curves.
