San Diego DUI defense attorney, Susan Hartman, of the Law Offices of Susan L. Hartman, recently attended The National Highway Traffic Safety Administration (NHTSA) and The International Association of Chiefs of Police (ICAP) approved DWI Detection and Standardized Field Sobriety Testing Practitioner Course, as presented by Mr. Robert La Pier. This is the very course law enforcement is trained in for DUI investigations, giving them the tools to determine if a person should be arrested for drunk driving.
During the training, which lasted three full days, Susan was tested through written exams and practical demonstrations. In the end, she passed the course and earned the certificate of completion.
