Cobb crashed in practice and could be seen with the cell phone in her hand after exiting the vehicle. The driver/owner was fined $5,000 for the rules violation plus an additional $2,500 because she was on probation for walking on a hot track during the May race at Dover.
The no-cell phone rule was implemented after the 2012 Daytona 500 when Brad Keselowski tweeted a photo of the fire under the red flag after Juan Pablo Montoya had crashed into a jet dryer.
A cell phone is considered an illegal electronic device because it has the potential to send signals to electronic components in the vehicle and is capable of downloading data, in addition to being used as a communication device. The only voice communication a driver on the track can have with the crew chief and spotter is through analog radio communications that can be heard by anyone with a scanner. espn
08/31/15 Camping World Truck Series driver Jennifer Jo Cobb may face a penalty for having a cell phone in her Truck during final practice Saturday at Canadian Tire Motorsports Park.
After crashing into a tire barrier and exiting her Truck, Cobb could be clearly seen on the Fox Sports 1 broadcast reaching back into her Truck and grabbing her cell phone while track workers assisted her to a waiting ambulance.
NASCAR officials said Saturday they would review the incident as part of their normal post-race review early next week.
In 2012, NASCAR banned drivers from having cell phones or any other computer-like devices in their vehicles.
The ban was prompted after Sprint Cup Series driver Brad Keselowski tweeted pictures from his phone during a red flag in the 2012 Daytona 500. Later that same season, Keselowski was fined $25,000 for again tweeting photos from his phone during a red-flag stoppage in action in a race at Phoenix.
“Smart devices and smartphones and other devices can have an effect on manipulating the technology that is now going to be in the cars, and we have to be careful with that," NASCAR Chairman Brian France said at the time.
“And so that's why our policy is that you're simply not going to be able to take a device into the car with you."
There was no immediate response for a request for comment from Cobb or her representatives. Jim Utter/Motorsport.com
