阅读下列短文，选择正确的答案。
Many rules govern (约束) drivers on American streets and highways. The most common one is the speed
limit(速度限制). The speed limit regulates how fast a car may go. On streets in the cities, the speed limit is
usually 25 or 35 miles an hour. On the highway between cities, the speed limit is usually 55 miles an hour.
When people drive faster than the speed limit, a policeman may stop them. The policeman gives them pieces of
paper, which are called traffic tickets. Traffic tickets tell the drivers how much money they must pay. When
the driver receives too many tickets, they may not be allowed to drive for a while. During the rush hour, (The
rush hour is when people are going to work or going home from work.) there are many cars in the streets, and
traffic moves very slowly. Almost every city in America has the rush hour. Drivers don't get tickets very often
for speeding at rush hour because they cannot drive fast.
