A dogleg and a chicane are two terms used in motor racing to describe a type of corner. A dogleg is a type of corner where the turn is made in an ‘L’ shape. A chicane is a type of corner that has two tight turns in opposite directions. Both types of corners can be used to slow cars down and make them take a longer route. The main difference between the two is that with a dogleg the turn is in one direction, whereas with a chicane the turn is in two directions. Both types of corners are used by race tracks to make the race more interesting and challenging.
