Prohibits motor vehicle stops for certain violations

This bill prohibits police from stopping a vehicle solely for minor violations like expired registration, unsecured license plates, or minor equipment issues (e.g., a single broken headlight). It allows stops only when an officer observes a "primary" violation (like speeding) at the same time as the minor issue. Drivers would no longer face stops for things such as a temporarily expired registration or a single non-working light, unless a more serious violation was also observed. The law directly affects drivers pulled over for these specific secondary violations, changing when stops can legally occur.
