Connecticut is one of a majority of states that has restrictions on passengers in the cargo bed of a pickup truck. For the most part, these laws are intended to protect younger passengers.
Connecticut law. Connecticut's law requires that: No person shall operate and carry a passenger younger than 16 years on in an open bed of a truck-type vehicle or other vehicle. However, such passengers are allowed to ride in such open spaces provided they are properly restrained in a safety belt. ( §14-272a(a)) The penalty is a fine of $50. No points are assessed.
Regardless of state law, you may wish to consult your policy to be certain that passengers in the bed or cargo space are covered. Because pickup truck beds are designed to carry cargo, not people, there are no federal requirements regarding passengers in cargo beds. Connecticut also has separate laws regarding child restraints.
Connecticut law prohibits transporting a dog in the "open rearward compartment of the pick up truck" on a public highway unless the dog is (1) in a cage or container or (2) secured in some manner to prevent it from being thrown, falling, or jumping from the truck (CGS § 14-272b). A violation is punishable by a fine of up to $50 (CGS § 14-296). The law does not require the dog to be restrained or secured if it is inside the vehicle.
