Final answer:
The statement that most accidents occur at speeds under 45 miles per hour is likely true, considering urban speed limits and other contributing factors to accidents.
Step-by-step explanation:
True or False. Most accidents occur at speeds under 45 miles per hour. This statement is likely true, as many collisions occur in urban areas where speed limits are typically lower than 45 mph. A high percentage of accidents happen at intersections or in residential areas where speed limits and actual driving speeds are often below this threshold. It is also notable that the occurrence of accidents is not solely dictated by speed alone but also by other factors such as driver error, environmental conditions, and vehicle malfunctions.
