SB 1078 Arizona Senate · 57th Legislature - First Regular Session

manufacturer plates; proof of contract

SB 1078 allows manufacturers in Arizona to operate unladen company vehicles (without registration) using special test plates. It directly affects manufacturers, their full-time employees, and contracted personnel who use these vehicles for business. The key provision requires a written contract or documented assignment on file inside the vehicle to permit personal use transportation, while prohibiting use on leased vehicles, cargo-heavy vehicles, or sold vehicles. This law modifies vehicle registration rules under Arizona Revised Statutes §28-4539. The bill passed the legislature and was signed by the governor in March 2025.
