Answer
Well Tammy, you did not say if she did it or not.  You only asked how they could prove it.

It's their word against hers. It's not common for a person to just pick out a license plate number at random and especially rare that that number would match a certain vehicle type.  Your insurance company should be contacted to properly defend your daughter.  They will need to see the car and conduct their own investigation.  If the other insurance company cannot prove their case, then they won't collect.  If there is no damage on the vehicle in the area of question, then your insurer may deny the claim.  If there is damage, then they should pay it.  If there is another witness, then that will have a bearing as well.

Good luck.
