Summary

This report, published by the Connecticut Department of Transportation in 2008, presents a comprehensive statistical analysis of motor vehicle traffic accidents occurring on publicly maintained roadways in Connecticut during 2006. The data is derived exclusively from police accident reports submitted to the Department, covering incidents involving fatalities, injuries, or property damage exceeding $1,000. The report aims to inform stakeholders of current traffic safety trends by categorizing accidents into general occurrences, alcohol-involved incidents, tractor-trailer collisions, pedestrian accidents, and motorcycle accidents. The methodology relies on a database compiled from standardized police reports, with specific limitations noted regarding data conversion from post-1995 forms and the exclusion of property-damage-only accidents on local roads. The analysis covers accident severity, rates per 100 million vehicle miles of travel, temporal patterns (hour, day, month), environmental conditions, geographic distribution, contributing factors, and demographic characteristics of drivers and victims. In 2006, Connecticut recorded 71,724 total reported accidents, resulting in 38,871 injuries and 311 fatalities. Over the decade from 1997 to 2006, total injuries decreased by 20%, and "A" (incapacitating) injuries decreased by 48%. Accident rates per 100 million vehicle miles also declined, with injury accident rates dropping from 114.28 in 1997 to 86.25 in 2006. Alcohol-involved accidents accounted for 1,775 total incidents, including 112 fatalities; 53% of these occurred between 9:00 PM and 3:00 AM. Motorcycles were involved in 1,225 accidents, causing 56 fatalities, representing 12% of vehicles in fatal crashes. Key findings highlight that 72% of accidents occurred on dry pavement and 79% under clear weather conditions, yet 54% of fatal accidents occurred during darkness. The primary contributing factor for fatal accidents was driver influence by alcohol or drugs (30.38%), followed by failure to grant right-of-way (23.55%). Fixed-object collisions accounted for 43% of fatal accidents. Demographically, drivers aged 16–24 were responsible for 28% of all accidents and 32% of fatal accidents. Male drivers accounted for 58% of all accidents and 82% of fatal accidents. The report underscores the significant role of impairment, age, and lighting conditions in severe crash outcomes, providing a baseline for future safety interventions.

Key finding
