A road course is a type of racetrack that features a combination of both left and right turns, as opposed to an oval track that only has left turns. These courses can vary in length and complexity, often incorporating elevation changes and various types of surfaces. Road courses are commonly used in motorsport events, including those for NASCAR, Formula 1, and sports car racing. Drivers on road courses must demonstrate a high level of skill, as they navigate tight corners and varying terrain. The layout of a road course can significantly impact race strategies, requiring teams to adjust their vehicles for optimal performance. Popular examples of road courses include Laguna Seca and Circuit de Spa-Francorchamps.
