Under Texas law, an adult can be held liable for damages if they knowingly allowed their kids' teenage friends to drink in their home.
Professor Ted Field with the South Texas College of Law says parents could get slapped with a huge lawsuit if a teen leaves their home drunk and gets in a wreck.
"It could include lost wages of the person who gets injured, it can include medical bills which can run up very quickly, obviously. It can include non-financial things like pain and suffering."
And if someone gets killed:
"It again could run into the same sorts of amounts, including surviving family members perhaps bringing a wrongful death action that would encompass losses going far into the future."
Under Texas law there is no blood alcohol limit for underaged drivers.
A teen driver with any detectable amount of alcohol in their system could be charged with a crime.
