Heard in the news over 3500 people have been ticketed over a recent period for driving while talking on the phone including cars and scooters.
They also said hands-free is okay.
Maybe, or not, explains why I did not get a ticket recently. I was riding a rented scooter with headphones on but no helmet like so many others on Liuqiu.
A policeman waved me down and told me put my helmet on but did not care about the headphones.
