B. Read the passage and decide whether the statements are TRUE or FALSE.

Traffic congestion is when vehicles travel at slower speeds because there are more vehicles than the road can handle. This makes trip times longer, and increases queueing. This is also known as a traffic jam. Congestion may result from a decrease in capacity, for example, accidents on the road or roads being closed. Bad road arrangements can also restrict the road's capacity. Increased traffic, for example by many cars leaving a school at the same time, can also cause congestion.

Where congestion is common, for example, because of commuting in big cities, several methods are used to relieve it. Cars may be banned in certain districts or certain times, or made to carry passengers or pay a fee, or people may use public transport, such as metro or subway systems, which travel independently and are not affected by traffic jams.
