Helmet rules
Required under age
Required under age 16
Applies to passengers
Yes
Standard
ANSI Z90.4 or Snell B-90 (a CPSC-certified helmet satisfies both).
Penalty
Civil infraction; the violation cannot be considered as contributing to the cause of an accident in any civil action. Failure to wear a helmet is not, by itself, grounds for a fine on a first offense if a conforming helmet is purchased.
Conn. Gen. Stat. § 14-286a authorises sidewalk cycling unless prohibited by local ordinance or official sign. Riders must yield the right-of-way to pedestrians and give an audible signal before overtaking. Hartford, New Haven and Stamford ban sidewalk cycling in their central business districts; check the local municipal code.
Connecticut's OUI statute (Conn. Gen. Stat. § 14-227a) applies only to operators of a 'motor vehicle,' and § 14-1(56) defines motor vehicle to exclude human-powered bicycles. Cyclists impaired in public may still face reckless-operation charges under § 14-289b or public-intoxication penalties, but the OUI consequences — including a 45-day licence suspension and ignition interlock — do not attach to bicycle operation.
White lamp on the front, visible from a distance of at least 500 feet.
Rear requirement
Rear reflector or light
Rear spec
Red reflector on the rear visible from a distance of 600 feet when directly in front of lawful upper-beam headlamps. A red rear lamp visible from 500 feet may be used in addition to the reflector.
Two abreast permitted; persons riding two abreast shall not impede the normal and reasonable movement of traffic. Conn. Gen. Stat. § 14-286b derivative of UVC §11-1205.
Bicycles are prohibited on all Interstate highways in Connecticut (I-84, I-91, I-95, I-291, I-384, I-395, I-684, I-691) and on most other limited-access state highways under Conn. Gen. Stat. § 14-298 and ConnDOT policy. Conventional state and US routes are open by default.
