Turnpikes; requiring Oklahoma Turnpike Authority to install road spikes on exit ramps; effective date.

HB 1634 requires the Oklahoma Turnpike Authority to install retractable road spikes on all exit ramps. These spikes automatically retract for safe exit traffic but deploy to block vehicles entering the ramp in the wrong direction, with clear signage and safety standards to prevent hazards. The bill directly affects all drivers using turnpike exits by adding a physical safety measure to prevent wrong-way entry incidents.
