The handle on the passenger side of 4 wheel drive vehicles that you hold onto when the vehicle tilts on extreme angles.
The Jesus Bar is so named because most passengers will grab it at the same time as shouting "Oh Jesus!"

A bar located in the disabled toilets which non-disabled or disables uses may grip in the event of a bad bowel movement, grog bow, the shits etc. Users can then let a "jesus!" rip while taking a dump and clenching the bar.
"I took a massive dump ! It was like I was shitting a knife, thank god for the Jesus bar in the disabled toilets"
