How tall do you need to be to drive bumper cars alone?

I think it's 48" because the only thing my youngest son couldn't drive alone was the big track and he's only 51" . But all the info is on the website and they will measure your child at the register before you pay for anything so you'll know what they can and can't ride. They'll also stamp their hand letting the ride attendants know what they are eligible to ride so there is no confusion. Very fair and we'll run place. My boys loved all three tracks.

They have a measurement chart, 3 feet have to be a passenger, it's over 4 feet they can drive on their own

I think 55 go to the website click the 3 lines upper right then click rides has charts
