Whether you’re new to Connecticut or you are a seasoned driver, it’s important to know the rules of the road to help avoid fines and accidents. While Connecticut follows many of the same requirements as other states, some rules and penalties can differ.
Here are some Connecticut-specific traffic rules and penalties that every driver should be aware of.
Left lane restrictions
In Connecticut, it’s best to stay in the right lane unless you need to move around something in your way, like a stopped car or debris. Use the far-left lane only when you’re passing slower traffic or preparing for a left turn. If you don’t follow this left lane rule, you could get a fine.
Turning at red lights
In Connecticut, you can turn right on red after coming to a full stop, unless a sign says otherwise. If you’re on a one-way street and turn left onto another one-way street, you can turn left on red if it’s allowed. Always check for cars and pedestrians before you go.
Distracted driving laws
Distracted driving is taken seriously in Connecticut. Using handheld phones or other electronic devices while driving is prohibited and can result in fines.
Seat belt and child safety
Everyone in your car should wear a seat belt, no matter where they’re sitting. Children under 8 or weighing less than 60 pounds need to be in an approved child safety seat. Not wearing a seat belt can lead to a fine.
Speed limits
Most highways in Connecticut have a speed limit of 65 mph, but rural roads often have lower limits. If you’re caught speeding, you might get a fine, points on your license, or even a suspension if it happens more than once.
Driving under the influence (DUI)
For drivers over 21, the legal blood alcohol content (BAC) limit is 0.08%. For those under 21, it drops to 0.02%. Refusing a breathalyzer automatically results in a license suspension. Penalties for DUI vary by age and the number of offenses.
For drivers over 21, a first DUI offense leads to a six-month license suspension. A second offense results in a one-year suspension, and a third or any further offenses result in a two-year suspension. For drivers under 21, a first DUI offense means a one-year suspension. A second offense results in a two-year suspension, and a third or any additional offenses lead to a three-year suspension.
Before your license can be reinstated after any alcohol-related suspension, Connecticut requires the installation of an Ignition Interlock Device (IID).
School bus laws
If you see a school bus with flashing red lights, always stop, no matter which side of the street you’re on, unless there’s a physical barrier between you and the bus. Not stopping can mean a fine for your first offense.
Move over law
If you’re driving and see a disabled car, a stopped emergency vehicle, a tow truck, or highway crews with flashing lights, always move over or slow down. Violating the law that results in injury to emergency personnel could result in penalties. A driver may also potentially face criminal charges if the incident results in a fatality.
Slow down in work zones
Connecticut asks all drivers to “Obey the Orange” by slowing down and being extra careful in construction and maintenance zones. Speeding in a work zone can result in penalties and repeat violations can lead to additional consequences. Watch for signs and workers to help keep everyone safe.
Yielding at rotaries and intersections
When you enter a rotary, always yield to cars already in the circle. Not yielding can lead to fines and points on your driving record.
Unlawful vehicle modifications
Some vehicle modifications are not allowed in Connecticut, like changing your engine, altering the frame or suspension, or changing the color of your exterior lights. If you want window tint, make sure it lets at least 35% of light through the side windows and isn’t too reflective.
Winter driving rules
Before you drive in winter, always clear snow and ice from your car’s hood, roof, and trunk. If you don’t, you could face penalties under Connecticut’s Ice Missile Law. If snow or ice from your car causes injuries or damage, the penalty can be even higher. Commercial drivers may also face increased penalties.
Driving rules for teen drivers
If you’re a teen driver under 18 in Connecticut, you’ll need to finish a training program approved by a parent or guardian and follow some strict rules about passengers, driving hours, and using electronic devices. Here are some of the main things to keep in mind:
- Learner’s permit holders may only have an instructor as a passenger.
- During the first 6 months with a license, only an instructor, a parent, or a licensed driver over age 20 (with at least 4 years of driving experience) may ride as a passenger.
- In the second six months, passengers are limited to immediate family members.
- Drivers aged 16 and 17 may not drive between 11 p.m. and 5 a.m., except for certain exceptions.
- After one year, drivers may carry no more passengers than there are seatbelts in the vehicle.
- All cell phone use, including hands-free, is strictly prohibited.
By keeping up with these Connecticut-specific rules, you’ll help keep yourself safe, avoid tickets, and enjoy your time on the road in the Constitution State. Remember to keep your Mapfre auto insurance policy current by contacting your independent agent in Connecticut.
