What is the speed limit on pit road during the Auto Club 400?

One of the most important things to know during a NASCAR race for drivers is the speed limit on pit road. It’s crucial they don’t go over and get flagged for speeding due to the penalty of having to pass through pit road again after they just exit it moments ago. This week’s race, the Auto Club 400, has a pit road speed limit of 55 mph.

Drivers will be whipping around the Auto Club Speedway at speeds around 200 mph. As a result drivers need to be even more conscience as they head for pit row and slow down in plenty of time or else NASCAR will be communicating the driver’s crew chief that they need to drive through pit road. As seen in past races this season, being penalized for speeding can cause a driver from being in the group of drivers near the need or being too far behind to have a chance of winning.

This season NASCAR has sensors in every zone of pit road calculating the speed of every car. They do this by taking how fast it takes each car to go from zone to zone and then converting it into a speed. Drivers can be caught speeding in any zone of pit road and not just when they enter. Once they leave their pit stall they can’t go over the speed limit of pit road until they officially leave it.

Drivers try to push the limit as much as possible to win the race off pit road. Yet, if they are even one MPH over the limit, then NASCAR can drop the hammer on them.
