During any NASCAR race, whether it is in the Cup, O'Reilly Auto Parts, or Truck Series, pit stops play a vital part in the action.
A well-executed trip down pit road can make a driver's race and gain them plenty of positions over their rivals. On the flip side, however, they can also lose out massively if they get things wrong.
Every season, for example, at most races, we see drivers hit with speeding penalties and sent to the tail end of the field by officials after exceeding the pit road speed limits. A very costly error.
But what are the speed limits at each track? And what do the rules actually say when it comes to pit road? Below, we've taken a look at the NASCAR rule book.

What are the rules on pit road?
Section 8.8.5 of the NASCAR rule book dictates that the following applies at all tracks:
- a) Vehicles must not exceed the pit road speed limit set for each event.
- b) Pit road speed enforcement begins and ends at the yellow speed lines at pit road entry and pit road exit.
- c) If a vehicle enters pit road to avoid an accident, it must reduce its speed for the entire length of pit road. If a caution period follows, its position will be determined by the freeze the field, provided it does not stop in its pit box.
- d) Vehicles may not speed to prevent losing a lap.
- e) Speeding during a pass-through penalty will result in an additional pass-through penalty.
Why does Atlanta (EchoPark Speedway) have two pit road speed limits?
All tracks on the 2026 NASCAR schedule have a single pit road speed limit that drivers must abide by, except at EchoPark Speedway (Atlanta). At that track, drivers entering pit road are subjected to a 90 mph limit at the entry, and then a 45 mph limit once they reach the pit stalls.
This was introduced in July 2023 following changes to the track layout at Atlanta in 2022 resulted in superspeedway-type racing and the pit road entrance being extended to turn three for 2023.
However, in the first 2023 Atlanta race, with a flat 45 mph pit road speed limit in place, some drivers began to fall behind the lead lap during green flag pit stops.
Therefore, ahead of the summer race at Atlanta that year, NASCAR introduced two separate speed limits to help minimize a team’s chances of falling off the lead lap during such pit cycles. It has remained ever since.
