There are a number of reasons motorists take off after a crash in the Pomona area:
Some motorists might be under the influence of alcohol or drugs, and they fear a DUI charge.
They may also fear being charged with other auto crimes associated with causing injury or death while under the influence of drugs or alcohol.
Some drivers may be so inebriated that they do not even realize that they have caused an accident, and drive off oblivious of the chaos or devastation they are causing.
Other drivers might flee because they are driving without a license, driving without registration, or driving without insurance.
Some may be driving a stolen car, or they may be wanted by the law for some other crime, like an outstanding warrant.
Others are just scared about what they have done, and are afraid to face the repercussions.
