Leaving the scene of an accident can mean big trouble. In accidents involving injury or death, a failure to stop can result in a Class 4 felony, punishable by one to three years in prison. If you fail to file a police report, you may be charged with a Class 2 felony, punishable by 3 to 7 years. If the other party died, you are now subject to a Class 1 felony, punishable by 4 to 15 years. When the accident only involves property damage, you may still be charged with a Class A misdemeanor, punishable by up to one year in jail plus a fine. An experienced criminal law attorney can help determine if the prosecutor has the proof he or she needs to get a conviction. Can they prove you were driving the car? Even if the evidence against you is overwhelming, an experienced attorney who is respected in the courthouse may be able to negotiate a better plea agreement than you could on your own.
