Various factors contribute to the risk of collision, including vehicle configuration, speed of activity, street plan, street condition, and driver ability, weakness because of liquor or medications, and behavior, eminently speeding and road dashing. The World Health Organization utilizes the term street traffic injury, while the U.S. Registration Bureau utilizes the term motor vehicle accidents, and Transport Canada utilizes the expression "motor vehicle traffic collision". This is on the grounds that the expression "accident" suggests that there is nobody to fault, though most traffic collisions are the consequence of driving impaired, over the top speed, diversions, for example, cell phones or other risky behavior.
