traffic stops; requirements

SB 1175 requires Arizona police officers to state the reason for a traffic stop and document it on the resulting traffic complaint or police report before questioning a driver about alleged violations. This directly affects drivers stopped for traffic offenses and police officers conducting those stops. The bill mandates this transparency unless an officer reasonably believes withholding the reason is necessary to prevent an immediate threat to life, such as in terrorism or kidnapping cases. The law applies to all traffic enforcement stops under Arizona law.
