Connecticut Vehicle Accident Statistics

Connecticut

In Connecticut, vehicle crash statistics for 2023 show that traffic fatalities increased to approximately 308 deaths, reflecting a rise compared to the previous year and continuing concerns about roadway safety across the state. Large trucks were involved in 37 fatal crashes, accounting for nearly 12% of all traffic fatalities, while thousands of residents were treated for crash-related injuries, including nearly 34,000 emergency department visits and hundreds of hospital admissions. Impaired driving, distracted driving, speeding and failure to wear seatbelts remained major contributing factors to serious and fatal crashes. Motorcycle fatalities, pedestrian crashes, and hit-and-run incidents also continued to be significant concerns statewide. Urban areas such as Hartford, New Haven and Bridgeport recorded higher crash volumes because of traffic density and congestion, while highways including I-95 and I-84 experienced frequent severe and multi-vehicle collisions. Overall, risky driving behaviour, aggressive driving, and distracted driving trends continue to contribute heavily to roadway injuries and fatalities throughout the state.

What do I do after an Accident in Connecticut?

A car accident can be overwhelming and stressful, even if it's minor. Knowing what steps to take immediately afterward can help protect your health, your legal rights, and your financial interests. Here are five essential things to do after an accident:

After accident
01
Check for Injuries and Call for Help

Your safety comes first. Check yourself and others for injuries and call 911 immediately if anyone is hurt. Even if injuries seem minor, it's important to get medical attention, as some symptoms may not appear right away. If possible, move to a safe location away from traffic while waiting for help to arrive.

02
Contact Law Enforcement

Always report the accident to the police. An official police report creates an objective record of what happened, which can be critical for insurance claims and legal matters. Cooperate with the officer, provide accurate information, and avoid admitting fault at the scene.

03
Document the Scene

If it's safe to do so, gather as much information as possible. Take photos or videos of the vehicles, damage, license plates, road conditions, traffic signs, and any visible injuries. Exchange contact and insurance information with the other driver(s) and attempt getting contact details from any witnesses in the area.

04
Seek Medical Evaluation

Even if you feel fine, consider seeing a medical professional as soon as possible. Injuries such as whiplash, concussions, or soft-tissue damage can take hours or days to show symptoms.

05
Notify Your Insurance Company

Report the accident to your insurance provider promptly and provide them with accurate details. Stick to the facts and avoid speculation. Keep copies of all documents related to the accident, including medical bills, repair estimates, and correspondence with insurers.

Important Connecticut Driving Laws You Should be Aware of

The Bicycle on a Highway Law: In Connecticut, it is illegal to ride a bicycle on a public highway or interstates. Additionally, the same speed limits apply as to cars. While the practical likelihood of a cyclist achieving high speed on a public road is quite low, it is possible that the state passed this law in anticipation of electric scooters and electrified bicycles, some of which are capable of high speeds.

The Walking Across the Street on Your Hands Law: In Hartford, Connecticut, it is illegal to cross any street while walking on your hands. This is another one of those unusual local ordinances that sparks some questions as to what prompted this law to be enacted. This historical ordinance is widely unenforced.

The Hunting while Driving Law: In Connecticut, it is illegal to discharge a weapon from a moving vehicle on public roadways. The Connecticut Department of Energy as well as the Environmental Protection Agencies strictly prohibit hunting from a moving vehicle. It is inhumane and poses a serious risk to other drivers and pedestrians.

The Dog in a Car Law: In Connecticut, it is illegal to leave a dog or any other animal unattended in a motor vehicle under conditions that could reasonably be expected to cause suffering or death to the animal, including extreme heat, extreme cold or lack of adequate ventilation. If an animal is found in an unsafe vehicle, local law enforcement officers have the authority to take whatever action is necessary to protect the animal, including breaking a window to rescue the animal, if necessary. This law reflects the state’s strong commitment to animal welfare and its determination to protect animals from the potentially fatal consequences of being left unattended in a motor vehicle.

Windshield Obstructions Law: In Connecticut, it is explicitly prohibited to operate a vehicle on a public road that has an obstructed windshield. The law explicitly forbids placing stickers, hanging large air fresheners and having trash on the dashboard in such a way that it blocks the driver’s view of the road ahead.

The Silly String Law: In Southington, Connecticut, it is illegal to use silly string in any public place, including on public roads and in public parking lots. Southington municipal law has officially and comprehensively put a brightly coloured and foam-covered end to your celebratory plans before they even had a chance to get started.

The No Honking After Dark Law: In certain parts of Connecticut, it is illegal to honk your car horn unnecessarily after dark in residential areas. Connecticut law requires you to resist that urge and proceed quietly through the neighbourhood.

The Truck Idling Law: In Connecticut, it is illegal for diesel powered trucks and other large commercial vehicles to idle their engines for more than three consecutive minutes while parked or stopped on a public road or in a public place. Connecticut's truck idling law reflects the state's strong commitment to environmental protection and air quality improvement and is strictly enforced throughout the state with significant fines for commercial vehicle operators who allow their engines to idle beyond the legally permitted three minute maximum.

The No Passing on a Hill Law: In Connecticut, it is illegal to attempt to pass another motor vehicle on a hill or curve where the driver's visibility of oncoming traffic is limited or obscured. Safe passing can only be done on a level, straight road where legally permitted. Passing related violations have been linked to a number of crashes, some of which result in fatalities. Connecticut takes this law very seriously and enforces it with significant penalties, recognizing the extreme danger posed by passing manoeuvres in locations where drivers cannot see oncoming traffic and the potentially catastrophic consequences of head on collisions on the state’s many hilly and winding roads.

The Road Work Zone Speed Limit Law: In Connecticut, drivers are legally required to reduce their speed and exercise extreme caution when passing through designated roadwork zones on public roads and highways. Connecticut strictly enforces its roadwork zone speed limits and imposes fines that are significantly higher than standard speeding fines for violations that occur in active work zones where road workers are present.

The No Texting While Driving Law: Connecticut takes distracted driving very seriously, as it is responsible for a number of accidents and fatalities annually. Under Connecticut General Statutes Section 14-296aa, it is illegal for any driver to read, write or send a text message using a handheld electronic device while operating a motor vehicle on a public road or highway. Connecticut's texting while driving law is a primary enforcement law, meaning that law enforcement officers can pull over and cite drivers solely for texting violations without needing any other reason to initiate a traffic stop.

The Emergency Vehicle Yield Law: In Connecticut, all drivers are legally required to immediately pull over to the right side of the road and come to a complete stop whenever an emergency vehicle approaches from any direction with its lights and sirens activated. Connecticut's emergency vehicle yield law is strictly enforced throughout the state and carries significant penalties for drivers who fail to yield to approaching emergency vehicles.

The No Spitting from a Bus Law: In Hartford, Connecticut, it is illegal to spit from any public transit vehicle, such as a bus, onto a public road or sidewalk. While most people would consider refraining from spitting out of a bus window to be basic common courtesy rather than a legal requirement, the fact that Hartford municipal law had to specifically address the issue of bus window spitting suggests that this was once a pressing enough issue to warrant the passing of this specific legislation.

The No Racing on Public Roads Law: In Connecticut, it is strictly illegal to participate in or organize any form of motor vehicle racing on a public road or highway under Connecticut General Statutes Section 14-224b. Street racing is highly dangerous and penalties for participating in this activity in the state of Connecticut can carry significant fines, license suspension and potential vehicle impoundment.

The Roundabout Navigation Law: Connecticut law requires that all drivers yield to traffic already circulating within the roundabout before entering. The state has been increasingly installing roundabouts throughout the state as a traffic calming and safety improvement measure. Local law enforcement officers actively enforce roundabout navigation rules and can issue citations to drivers who fail to properly yield when entering a roundabout, as improper roundabout navigation is a common cause of traffic accidents for drivers who are unfamiliar with the rules governing roundabout use.
