Signs missing, wrong or incomplete. Example: A sign says that anyone parking illegally in accessible parking spots will be towed, but fails to name the towing company or provide a phone number.

When testimony is finished, clarify status as witness.

It is the judge who permits the witness to leave the stand by excusing the witness. This means the witness is free to stay in the court or leave. The witness may however, be required to remain for further testimony or return as the court instructs. If the latter occurs and the witness has other matters to attend, the witness may explain this to the court and ask for another time to attend. The court may or may not grant the request.

Accept the unfamiliarity of testifying rules.

The main objections raised by counsel to expert testimony arise because of hearsay and a proper foundation for the opinions expressed. Objections may be to the question asked or the answer given. When an objection is raised, the witness should refrain from speaking until the court instructs otherwise. The witness should not attempt to justify comments unless asked to do so. The witness is not to respond to an objection, argue about comment or whether or not the evidence should be heard. After an objection is raised, the court rules on the objection and instructs counsel how to proceed.
