Relating to the emergency installation and use of a mobile tracking device on a vehicle by an authorized peace officer.

HB 2178 allows Texas peace officers to install and use mobile tracking devices on vehicles without a court order in emergency situations. This applies only when officers have probable cause to believe the vehicle is involved in specific serious crimes (like certain felonies under Penal Code Sections 38.04/38.06) and immediate tracking is necessary to prevent death, injury, property damage, or a fugitive's escape. Officers must obtain a judge’s approval within 72 hours of installation, and if they fail to do so, all evidence gathered during that period cannot be used in court. The bill directly affects law enforcement practices and vehicle owners’ privacy during active criminal investigations.
