Connecticut Bicycle Laws

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.

Statute

¹

Confirm equipment fit with the helmet size calculator before relying on an age rule alone.

Statewide rule

Allowed with conditions

Notes

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.

Statute

¹

A bell does not replace yielding or signaling, but it can warn other path users; compare bike bells and horns.

Penalty

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.

Statute

¹²

If alcohol or drugs may impair the rider, do not ride; arrange another way home and secure the parked bike with a lock suited to the theft risk.
