Banked turn
A banked turn (or banking turn) is a turn or change of direction in which the vehicle banks or inclines, usually towards the inside of the turn. For a road or railroad this is usually due to the roadbed having a transverse down-slope towards the inside of the curve. The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal.
Sprinters leaning into a turn on a banked indoor track
Most indoor track and field venues have banked turns since the tracks are smaller than outdoor tracks. The tight turns on these small tracks are usually banked to allow athletes to lean inward and neutralize the centrifugal force as they race around the curve; the lean is especially noticeable on sprint events.
