Frequently Asked Questions

  • What is the non-emergency contact number for the local police station in Ontario, California?

    (909) 986-6711 is the Ontario Police Department's non-emergency dispatch line.

  • What are the key points of attack that DUI defense lawyers in Ontario take when opposing the prosecution?

    When opposing the prosecution, DUI defense lawyers in Ontario will examine the blood alcohol level of the suspect during the arrest and look for holes in the testing procedure or the interpretation of results. Attorneys also scour the procedures followed during the initial traffic stop and determine if the police had probable cause to stop the defendant.

  • What are the kinds of hearings that a DUI defendant in Ontario faces?

    A DUI defendant in Ontario faces administrative procedures with the Department of Motor Vehicles. This process is not judicial, and the hearing officer exercises the powers of jury, judge, and prosecutor, with the sole issue being whether or not to suspend the perpetrator's license. The court trial follows and examines the existence of guilt beyond a reasonable doubt in the case's criminal aspect.

  • Can a DUI suspect in Ontario who is sure that the police have nothing to prove guilt ask to be set free?

    Yes, there is a way for a DUI suspect who has been stopped at an Ontario checkpoint to be sent home without issues. The individual may refuse to answer police questions because of the right against self-incrimination and then ask if the cops are instituting a formal arrest. Since the police legally cannot arrest or search a person without a warrant or probable cause, they cannot detain a defendant if they have no evidence.

  • What are the law enforcement, judicial, and administrative offices that a resident of Ontario should keep in mind concerning DUIs?

    A resident of Ontario should keep in mind that the arresting officer who will conduct a DUI stop would come from the California Highway Patrol Rancho Cucamonga if the individual is on a freeway. The case will end up in the criminal courts of the Rancho Cucamonga District at 8303 Haven Avenue. Administrative DUI cases take place at the Department of Motor Vehicles office in San Bernardino, which is at 1845 Business Center Drive South #212.
