What Roads that function as expressways and divided highways have high speeds and greater risk of crashes?

Roads that function as expressways and divided highways typically have higher speeds due to their design, which allows for faster traffic flow with fewer intersections and traffic signals. However, these high-speed environments can increase the risk of crashes, especially when driver behaviors such as speeding, tailgating, and distractions come into play. The presence of merging and weaving traffic, as well as limited visibility in certain sections, can further contribute to the likelihood of accidents. Additionally, the severity of crashes on these roads tends to be higher due to the increased kinetic energy involved at higher speeds.
