Yes, it does beep a lot but you can adjust the volume to low. Source: we had a 2025 replacement Yaris. It's annoying but the older ones' seat belt alarm is even more annoying, although I use the seatbelt at all times. It also turned me off, not wanting to get a new post-2025 Toyota. Now they all have mandatory alcohol testers and speed alarms. Use hand sanitizer and you have to Uber to work. No thanx. I'll keep my old car.
Sorry new Toyotas have mandatory alcohol testers? Which locale are you in? I’ve heard of mandatory breathalysers for work vehicles or DUI drivers but all new cars?
