Vehicle barrier systems that can selectively move a barrier arm between a first position that prevents a vehicle from passing, or a second position that allows the vehicle to pass, wherein the barrier arm moves both upwardly away from a travel path and laterally along the travel path in a direction away from the vehicle. The barrier arm movement thereby leads the driver of the vehicle through the barrier system in a sweeping or leading movement. In some embodiments, an actuator assembly of the barrier system includes a breakaway assembly coupled to the barrier arm. In the event that an abnormal force (e.g. vehicle strike, vandalism, etc.) applied to the barrier arm exceeds a predetermined threshold, one or more drive magnets of the breakaway assembly disengage from the one or more magnetically-attractive elements to prevent damage to the barrier system.
