a car driver
"In my country,the driver and the person
sitting in the front passenger seat
must wear seat belts"
That's the law.
The people in the back seat
don't have to wear seat belts,
but of course,it is a good idea."
a pedestrian
"In some cities in my country,
you must cross the street at the crosswalk.
I live in a small town,
and we don't have to do this.
We cross the street anywhere we like!"
a motorcyclist
"In my country,you have to be seventeen
to drive a car,"
but you can ride a small motorcycle
at the age of sixteen.
To ride one of these motorcycle,
you don't have to have a driver's license."
