Drivers who violate state and local laws regulating the operation of motor vehicles are generally subject to fines and points assessed against their operator's license. Each state's laws vary widely as to how they regulate the operation of motor vehicles within their state.
Most traffic offenses are for driving at speeds above the legal limits.
Since the courts have repeatedly held that drivers impliedly consent to the taking of breath, blood or urine when a police officer has reason to believe the driver is under the influence of alcohol or drugs, the usual rights against testimony against oneself are abrogated. Operating the motor vehicle without a valid operator's license and in some states, operating a motor vehicle without proper proof of insurance are also viewed as important offenses and may carry the possibility of substantial fines and denial of driving privileges. Violation of traffic signs and for causing accidents are other important areas in which the driver can run afoul of the law. The laws affecting driving have become increasingly complex and often require the assistance of an attorney in protecting the rights of the driver. Traffic offenses can cover a broad range of offenses from minor misdemeanors, requiring no personal appearance in court and punishable by a small fine to serious felonies involving punishment by incarceration in local jails or state penitentiary.
