Passengers on board a Greyhound bus this week were forced to stage a mutiny to get rid of the female driver who they say was falling asleep at the wheel and using tweezers to keep herself awake by pinching her own cheeks.

The bus was traveling from Phoenix, Arizona, to Dallas, Texas, on Thursday. It is a 21 hour journey which costs between $150 and $200. There were around 60 people on board and it was daylight at the time.

On Thursday, passengers said they noticed the bus swerving on the road.

When they approached the driver, they claimed she was repeatedly nodding off. In a desperate attempt to keep herself awake, the woman allegedly pinched herself in the face with tweezers.

The passengers begged her to pull over to avoid an accident but she refused.

Eventually, several passengers stormed to the front of the bus to give her no choice.

Their confrontation was filmed by another passenger. Shockingly, despite being yelled at and yelling back, the female driver kept on driving through the argument.

She only stopped once passengers called highway patrol for an escort.

The passengers have since told how they were in fear for their lives throughout the journey.

'We politely asked her four times to pull over. I got to the point where we saw her going like this (nods head) and just dozing off,' Jasmine McLellan told CBS.

'The bus was leaning little and that's when people started to really worry.

'She was using techniques to try and stay awake and I think that was the initial concern.

'We would go over the white line and everybody would be like wake up and she had tweezers she was poking herself with tweezers to keep herself awake it was awful.

'It got to the point where we had to raise our voice pull over we have children on this bus pull over,' Phillip Hurd added.

Eventually, the bus (above once it had reached Dallas) was pulled over when passengers called police. A Border Patrol escort got it to a safe place and the driver was replaced

Greyhound said it was investigating the incident and that it takes the matter seriously.

'We are currently looking into these allegations, as we take the issue of driver fatigue very seriously,' a spokesman told DailyMail.com in a statement.

'Because safety is the cornerstone of our business, we take necessary precautions to prevent drivers from falling asleep while driving and we make it easy for drivers to be reassigned if they do feel fatigued or don't feel confident that they can operate the bus safely for any reason.

'Our drivers are in regular contact with our dispatch office, and if they state they are feeling tired or fatigued, they are immediately removed from the schedule for at least 12 hours to allow them to get some rest.

'Once they feel alert and able to return to work, they may do so,' they added.
