Relief Driver

A relief driver is a substitute driver who takes over for another driver during a motorsport race when the original driver cannot continue or needs a break.

Relief drivers are most commonly used in endurance racing, where races can last 12 to 24 hours or even longer. These marathon events are extremely physically demanding, and no single driver can safely handle the entire race alone. Teams typically rotate between two or three drivers, with each taking shifts behind the wheel while others rest and recover.

The need for a relief driver can arise for several reasons. In endurance races like the 24 Hours of Le Mans, driver changes are planned and required by the rules. However, relief drivers may also be needed unexpectedly if the original driver becomes injured, falls ill, or experiences extreme fatigue during the race.

Historically, relief drivers were more common across all types of racing. In the early days of motorsport, cars lacked modern safety features and comfort systems, making races much more physically punishing. The first Indianapolis 500 in 1911 saw relief driver Cyrus Patschke take over for Ray Harroun during the race.

In modern NASCAR racing, relief drivers have become less common due to custom-molded seats that fit only the primary driver. However, they still appear occasionally when drivers face health issues or other emergencies. Darrell Wallace Jr., for example, made several relief appearances in 2017.

Different racing series have varying rules about driver substitutions. Some specify how points are awarded when relief drivers participate, while endurance racing rules often mandate minimum and maximum driving times for each team member. Understanding these regulations is crucial for teams planning their driver lineups.

The role of relief driver requires skill and mental preparation, as they must be ready to jump into an unfamiliar car setup at a moment's notice and perform at the highest level of competition.
