Autocross courses are laid out on a large area made of asphalt or concrete, or sometimes a mixture of both. The course is lined with cones. Each cone will have a chalk line drawn around the base, which allows the cone to be replaced correctly if it is disturbed,. This also allows corner workers to determine if a driver has disturbed it enough to acquire a 2 second penalty. A cone knocked over on its side results a time penalty of 2 seconds. A cone that been knocked completely out of its box also results in a time penalty of 2 seconds. However, a cone that is bumped, but is upright and still touches its chalked-lined box is not penalized at all (Workers still need to put it back into the chalk box.)
