Regarding pit lane speeding, quote from Jeff Gordon regarding Montoya's exit speed infraction from last year, which contributed in Montoya not winning the race:

"The bottom line is that he was speeding," Gordon said. "To NASCAR's defense their system that they have, you can't dispute it. They'll show you exactly which zone [you speed in]. After the race you can go find it and I've not heard one person come back and say that, 'Well, they were absolutely wrong.' Once they show them everything I would dispute the person that feels like they were in the wrong because their system is very accurate. But what I'm not confident in is our system. We have to be able to go and push the limits of that speed. I play it conservative and if my system breaks down I'm going to get caught speeding. If I play it too aggressively I'm probably going to get caught speeding. So it's still in our hands."

Due to the number of pit speed violations in the Nationwide race at Fontana, at the Cup drivers meeting Sunday morning, drivers were specifically warned by NASCAR about speeding on pit lane. The easiest zone regarding speed is the pit closest to the exit point of the track where the car is past the last timing zone start point.

While there is always the chance of a technical malfunction, NASCAR records and makes available to the Teams the speeds at a number of check points along the pit lane from yellow line to yellow line, , while allowing for a variance, i.e., if the speed limit is 55 , then the infraction is not enforced until the speed is 60. Just seems overall in all the races there are more announced exit speed infractions than entry.

Upon entry, the drivers are in a specific gear and use the tach as their reference point which is equated to MPH, in the absence of a speedometer.

During the reentry phase onto the track they are accelerating thru the gears along with the tires spinning ( higher RPM ), without the guidance of a specific tach reference point, and at the same time very aggressively attempting to improve their track position. The replays of the cars crossing the pit, upon exit, yellow line indicate how close the cars are attempting to gain and/or not lose track position.
