Cars must be driven on the left side of load in Japan! Do you know?
It's a general rule, one of the law.
Why did I bring in the theme?
Because minding it, I go to school by my bike everyday.
Do you understand? It will be a little hard to understand the only one sentence.
I'll show you why I mind the rule when I go to school by my bike.
Though it is easy reason;
Bike is one of cars.
So bike is driven on the left side of load in Japan too.
But in fact, this law has been decided and enforced recently.
If you drive your car or your bike in Japan, you mind left-hand-traffic.
Enforce : 施行する
Left- hand-traffic : 左側通行
