Relating to the authority of a reserve peace officer.

SB 2144 clarifies the authority of reserve peace officers working under sheriffs and constables. It gives sheriffs and constables the discretion to allow reserve deputies to carry weapons or act as peace officers at all times (not just during active duty) or to limit that authority to only when they're working. The bill requires reserve officers to hold proper licenses for activities requiring them under Texas law, prohibits using police vehicles for private gain outside their county, and restricts police escorts to county-based routes. This directly affects reserve deputies for sheriffs (under Section 85.004) and reserve deputy constables (under Section 86.012). The bill focuses on defining operational boundaries for these unpaid or part-time officers.
