The graph shows the changing rate of car accidents in Walton city in 1990. The first two months of 1990 showed an increasing trend. The rate rose to 32 in March but fell to 26 in June. From June on the rate was rising again and reached the peak point 39 in August. After August the rate began to decline,and ntually ped to the lowest point 16 at the end of the year.
The highest rate in August was due to unfavorable weather conditions. Humidity and high temperature make drivers impatient, which easily leads to car accidents. The high rate in the first half of 1990 was also caused by the bad weather condition. In Walton City the excessive rain comes at early spring.
