It used to be 10 and up as long as you signed all the waivers but it could have changed

It went to 16, but I'm sure its dropped. Do not quote me on that..... but that was years ago.

Is there a min age to get in the pits at delaware?if so what is it?

9. No one under the age of 18 is allowed in the pits without proper parental consent forms being completed BEFORE arriving at the racetrack.  MINORS MUST BE APPROVED BY SPEEDWAY RACE DIRECTOR BEFORE THE DATE OF THE EVENT.  Minors found to be in the pit area without proper parental consent forms filled out can be – prosecuted for trespass to the full extent of the law and/or receive fine or suspension from the speedway.  Proper forms will be available at the speedway website and only need to be filled out once per year.
