Lindsay Lohan has allegedly blown off YET ANOTHER legal case ... this one involving a nanny who claims LiLo smacked her with a Maserati.
TMZ broke the story ... Linds was sued last year by Nubia Del Carmen Preza, who claims LiLo ran a red light, injuring her and barely missing the baby stroller she was pushing back in 2010.
The nanny's lawyer filed legal docs demanding that Lindsay answer certain questions about the incident, but apparently Lindsay blew it off and never responded.
As for what questions the nanny wanted answered ... did you hit me, did you fail to stop, was someone else in your car -- stuff like that.
A hearing is set for May 8 where a judge will decide whether to sock Lindsay with fines for ignoring the questions.
Lindsay won't be there, of course, but she has a good excuse this time -- she'll be a few days into rehab.
