A breakaway assembly comprises a first assembly member adapted for connection at one of its ends with a movable member of a vehicle barrier device, and a second assembly member adapted for connection at one of its ends with a gate arm of the vehicle barrier device. A breakable member is releasibly connected at one of its ends to the first assembly member, and is releasibly connected at an opposite one of its ends to the second assembly member. The breakable member is constructed so that it preferentially breaks between the first and second assembly members in response to a determined impact force imposed on the gate arm to spare the gate arm from serious damage, to ease and expedite repair operations, and to reduce the costs associated with maintaining and adequate inventory of replacement parts.
