Motorways help people travel quickly and cover long distances, but they also cause problems. What are the problems of motorways and what solutions are there?

Motorways are very popular in many countries because of their convenience to travel comfortable and shorten the long distances. However, motorways also have negative aspects such as dangerous traffic and population. Indeed, they need to be improved. In this essay, the drawbacks of the motorways and some effective methods to overcome are analysed.
One major problem of motorways is that they can be dangerous. In many countries, the speed limits on motorways are very high. This means that any accidents are more likely to be serious and involve many vehicles. Sometimes in bad weather, several vehicles crash into each other leads to many dead or injured people. This problem could be solved by some possible methods. First of all, all drivers must have driving licenses and educate carefully how to drive safely on the freeways. In addition, special signs could be displayed when driving conditions are bad to make people drive more slowly and safely.
The other disadvantage of motorways is pollution. When travelling, many vehicles could produce many emissions to the environment. Moreover, noise pollution is also a big problem for the residents. However, governments could help to solve these problems by making the environmentally-friendly cars cheaper and putting up sound proof fences.
In conclusion, motorways are really necessary and useful in spite of the problems of them. With careful preparation and planning, the problems they caused could be reduced. People today are also more aware of environmental issues. As a result, cars and another means of transport are becoming more environmentally- friendly.
