Many of the cases involve someone who is scared because they do not have a license or believe they will be arrested because they caused the crash.  It is far worse to leave the scene than receive a ticket at the scene. We have seen cases in which the party that left was not a contributing factor in the crash and would not have even received a ticket but now had to be responsible for the crime.  Since Leaving the Scene of a crash is a crime there will likely be consequences.  It is recommended that you contact the police to provide your information.  If you are working with a detective, arrangements can be made to turn yourself in and you do not have to be afraid that you will be arrested unexpectedly.
