Current Le Mans regulations mandate that three drivers share each competing car.
The 24 Hours of Le Mans is a 24-hour team event, so driver changes are essential for managing fatigue. Modern rules also limit individual driving time: a driver may generally drive no more than four hours within a six-hour period and no more than 14 hours overall.
The wording can cause confusion because two-driver entries have sometimes been possible in practice. Careful scheduling can allow two drivers to complete the race within the individual time limits; Jeroen Bleekemolen and Cooper MacNeil did so in 2014. That exceptional possibility does not change the standard regulatory requirement that each car be shared by three drivers.
Historically, Le Mans began with fewer restrictions. Early competitors sometimes attempted to drive alone, while two-driver crews remained common for decades. By the late 1980s, the rules had shifted toward requiring at least three drivers, reflecting the speeds, length and physical demands of modern endurance racing.
