Like many communities on the Front Range, Castle Rock is growing rapidly. According to the estimates, the town population reached nearly 90,000 people at the end of 2024 and may reach as many as 140,000 people in the coming years.
With such substantial growth, more and more motorists and commercial vehicles are using the transportation infrastructure in Castle Rock each year. At Casares Injury Law, we believe that road safety has become more important than ever before.

When do Collisions Peak in Castle Rock?
The time of year has a significant impact on road safety. During winter months, road conditions may be affected, while warmer summer months may have a higher volume of traffic.
During the observation period, more collisions occurred in June of 2021 (92) than in any other single month. That year, collisions peaked in the late spring and summer months. However, in each other observation year, the winter months of December, January, and February had the most crashes.
Puttin it All Together
Regardless of when, where, and how often Castle Rock residents and visitors drive, we believe that having an understanding of the traffic safety situation can help keep them safe. While you cannot mitigate all risks from careless and negligent drivers, knowing when and where the risk may be allows motorists to make decisions and adjust behaviors that may lead to fewer collisions.
