Pit Stop

A pit stop is a stop a race car makes in the pit lane during a race, where a crew performs tasks such as refueling, changing tires, making repairs, adjusting the car's setup, or swapping drivers in endurance racing formats. Pit stops are a required and strategic part of nearly every major motorsport series, since cars cannot carry enough fuel or tire life to complete most race distances without stopping, and the specific timing and duration of pit stops are a central element of race strategy, not just a mechanical necessity.

The speed and precision of a pit stop varies enormously by series and by what the stop involves. Formula 1 pit crews have developed tire-only stops into one of the most refined choreographed operations in sports, with top teams completing a four-tire change in roughly two seconds from the moment the car stops to the moment it is released, a benchmark that has driven intense competition among F1 teams over equipment and crew training. Endurance races such as Le Mans and IMSA involve longer, more complex pit stops that can include refueling, tire changes, and driver swaps within a single stop, taking considerably longer than a Formula 1 stop but still executed under strict time pressure.

Pit stop strategy is a major factor in race outcomes across series: teams weigh the tradeoff between pitting early to gain fresh tires or fuel against losing track position, and undercut and overcut strategies, where a team pits earlier or later than a rival specifically to gain a track position advantage once tire wear or fuel loads are accounted for, are common tactical tools. Pit lane speed limits, mandatory minimum stop counts in some series, and penalties for unsafe releases or equipment left in the pit lane are among the regulations that govern how pit stops are conducted.
