What Should I Do After a Car Accident in Connecticut?

In case of an accident in Connecticut, drivers should follow these procedures to lessen potential accidents and property losses:

1
Try moving off the mainline

In a collision, drivers should safely drive the car to a safe lane or the side of the road. High-traffic interstate roadways increase the risk of multi-vehicle collisions due to potential visibility restrictions and adverse weather conditions.

2
Turn on the hazard lights and use flares and cones

Drivers should then engage their vehicle's hazard lights, signaling potential danger to approaching drivers. For enhanced visibility, particularly in adverse weather conditions, drivers should consider using roadside flares, cones, or flags. However, drivers should place traffic control devices at a safe distance from the crash to provide ample reaction time for passing motorists.

3
Remain at the scene

The state prohibits anyone involved in a traffic collision from fleeing the scene. Drivers should remain at the crash site until instructed otherwise.

4
Check for injury

Individuals should check if any people have suffered injury in the crash. In case of a serious injury, people should not move the patient but call a medical emergency team to assist.

5
Notify local law enforcement

Though drivers are not obligated to call the police, any crash that results in injury, death, or property damage exceeding $1,000 should be reported within five days. If a police officer arrives at the scene, drivers should cooperate with them to ensure their report accurately reflects the events.

6
Record information

Drivers involved in an accident should document the names and contact information of all other parties, including passengers, witnesses, and emergency personnel attending the scene.

7
Take images for documentation

Drivers should photograph the collision. They could be used as references to determine the cause of the crash and as evidence in judicial procedures or insurance claims.

8
Exchange information

The state requires all individuals involved in a traffic collision to exchange their information. These include names, addresses, insurance details, license information, and car registrations. If the driver does not own the car, they should provide the owner’s name and address.

9
Seek help from an attorney

For the best legal outcome, it is recommended that drivers seek assistance from attorneys to ensure their rights are not violated.

10
Notify the insurance company

If a driver wants to file an insurance claim seeking compensation, they should notify their insurance company.

11
Keep a record of the incident

Drivers should keep essential documents in case of legal proceedings. These documents include police statements, reports, and insurance information.

Connecticut Driving Laws and Facts

Every driver must understand the state’s traffic laws to prevent accidents and save lives on the road. These laws include:

Hands-Off Law

The state prohibits using handheld devices in the car, including if the vehicle has stopped in traffic or at a stop sign or stop light.

Drivers over 18 are allowed to use hands-free devices to answer calls.

Drivers between 16 and 17 are prohibited from using handheld and hands-free devices.

Drivers are exempt from the law in case of an emergency or drivers 18 years or older working in emergency response.

Seatbelt Law

Seat belts are mandatory for all vehicle occupants.

For children younger than two years or who weigh less than 30 pounds, their seats must be facing the car’s rear.

Children aged five to eight must be in a child safety seat or booster seat that meets safety standards.

Children aged eight who cannot fit in a booster seat must use a lap and shoulder belt.

Children aged 13 should always ride in the back seat.

Teenage Driving Laws

In the state, the legal age for driving is 16 years. Students must take a driving course and pass both vision and written tests.

Teenage drivers must have completed at least 40 hours of behind-the-wheel training before applying for a license.

The state does not allow minor drivers to have a passenger unless it is a driving instructor who is at least 20 years old with a valid driving license.

Teen drivers are restricted from driving between 11 p.m. and 5 a.m. unless assigned a driver in the Safe Ride Program, or the minor driver travels for work, school, a medical emergency, or religious activity.

Motorcyclists

Riders aged 16 and 17 must always wear helmets on roads.

The state prohibits drivers aged 16 and 17 from carrying passengers for six months after receiving their motorcycle endorsement. Additionally, drivers aged 18 or older are prohibited from carrying passengers for 90 days after their endorsement.

Lane Camping

On multi-lane highways within the state, the left lane is designated exclusively for overtaking or passing other vehicles.

Vehicles occupying the left lane should maintain a speed exceeding traffic in the right lane.

Vehicle Registration and Insurance

All vehicles must maintain minimum liability insurance coverage. This protects drivers financially in case of accidents caused by the driver.

For drivers under 21, their BAC should be lower than .02% while driving.
