Connecticut’s Deer Mating Season Spurs Increased Roadway Hazards, AAA Advises Caution

As autumn ushers in the rutting season for white-tailed deer (Odocoileus virginianus), Connecticut experiences a surge in vehicle-deer collisions, prompting AAA to urge drivers to exercise heightened vigilance. This seasonal increase in activity is driven by the deer’s biological imperative to reproduce, which often results in unpredictable and erratic movements near roadways.
Official data from the Connecticut Crash Data Repository recorded 387 incidents involving deer collisions from October through December of last year—equating to roughly one crash every six hours. Peak occurrences tend to align with dusk, a time when deer become particularly active.
Lauren Fabrizi, spokesperson for AAA Northeast, emphasized the dangers posed by these collisions: “Impact with a deer can be extremely hazardous, sometimes propelling the animal through the windshield and causing serious injury or fatality to vehicle occupants.”
Biological Drivers Behind Risky Deer Behavior
During the rut, male white-tailed deer increase their movements significantly as they search for mates, often venturing into unfamiliar or hazardous areas, including busy roads. This maternal drive intensifies movement around dawn and dusk, aligning with lower visibility periods for drivers.
AAA specifically cautions motorists to be alert during evening rush hours and overnight. These temporal patterns correlate closely with peak deer activity related to reproductive behaviors.
High-Incidence Areas and Safety Recommendations
Several Connecticut towns exhibit elevated rates of deer-related crashes in the fall months, including:
- Simsbury (18 crashes)
- Farmington (17 crashes)
- Groton and Wallingford (tied at 14 each)
- Middletown (13 crashes)
- Shelton and Stonington (tied at 11 each)
- Berlin, Bethel, Coventry, East Windsor, and Ridgefield (each with 8 crashes)
AAA advises drivers to maintain a vigilant lookout for deer along these routes but warns against abrupt evasive actions. Swerving or sudden braking can increase the risk of more severe accidents.
According to the AAA release:
- Swerving right risks collision with stationary roadside hazards such as trees or poles.
- Swerving left could cause fatal head-on collisions with oncoming vehicles.
- Abrupt braking may cause the vehicle to jolt forward, potentially propelling the deer through the windshield.
Statewide Impact of Wildlife-Vehicle Collisions
Nationwide figures underscore the severity of animal-related collisions. In 2023 alone, 218 fatalities and over 40,000 injuries resulted from crashes involving live animals. Thus, the Connecticut data reflect a localized portion of a broader public safety concern during wildlife mating seasons.
Given the biological urgency of deer to mate in the fall and the predictable rise in collision frequency, wildlife experts align with AAA’s call for measured driver awareness and caution on Connecticut’s roadways.
