St. Louis, MO – Missouri motorists traveling along Interstate 70 and other major highways face increased deer related collision concerns this Halloween weekend as November approaches, bringing one of the most active periods for white tailed deer movement.
According to seasonal guidance from wildlife and transportation authorities, the annual deer mating season, commonly called the rut, increases deer movement and creates additional hazards for motorists traveling through rural and suburban areas.
The seasonal concern extends across Missouri, including St. Louis, Kansas City, Columbia, Jefferson City and Springfield.
Drivers traveling along I 70, I 44, I 55 and I 35 should remain especially attentive near wooded areas, agricultural fields and highway corridors where deer may cross unexpectedly.
During the fall breeding season, male deer often travel greater distances searching for mates, increasing the possibility of sudden roadway encounters.
These movements can occur at any hour but are particularly concerning around dawn and dusk, when deer are commonly active and visibility may be limited.
The return to standard time Sunday, Nov. 1, will also bring earlier evening darkness by the clock, adding another consideration for commuters.
Motorists traveling after sunset should watch for movement along road shoulders, especially near tree lines, fields and rural intersections.
Wildlife safety guidance encourages drivers to reduce speed where visibility is limited, scan both sides of the road and avoid distractions.
Drivers should also remember that deer frequently travel in groups. Spotting one animal near a roadway may indicate additional deer nearby.
If a deer enters the roadway directly ahead, motorists should brake firmly while maintaining control rather than swerving into another lane or leaving the pavement.
The seasonal hazard can affect both rural highways and suburban streets near parks, wooded neighborhoods and undeveloped land.
With November beginning Sunday, Missouri drivers should anticipate continued deer movement throughout the coming weeks.
Additional caution during early morning and evening travel may help motorists reduce the likelihood of a deer related collision.
