It also has several tight corners, like the Bus Stop in turn two, which comes right after the long Cimarron Straight and forces a speed drop from 120 mph to 40 mph for drivers to avoid going out of track. Each of the turns in Hallett Motor Racing Circuit comes in a particular location in the field to take full advantage of the elevation changes to create an exciting path for racing.
There is no default racing orientation in the Hallett Motor Racing Circuit because of the ample runoffs at both sides and the very symmetrical layout of most turns.

Average speeds are also very similar, with 76 mph when running counterclockwise and 74 mph when running in the opposite direction.
