No such accident report or copy thereof shall be used as evidence in any trial, civil or criminal, arising out of an accident, except that any officer above named for receiving accident reports shall furnish, upon demand of any person who has, or who claims to have, made such a report, or, upon demand of any court, a certificate showing that a specified accident report has or has not been made to the chief of police solely to prove a compliance or a failure to comply with the requirement that such report be made in the manner required by law.
