Bench seats are an out of date seat design on some roller coaster cars. The common roller coaster bench seat is a flat-seat with no divider between the riders. This allows riders to slide across the seat. Coaster riders will find these on older wooden roller coasters and some mine ride roller coasters. Most modern, or even remotely modern roller coasters are designed with seat dividers or bucket seats to comply with contemporary safety concerns. Even the American Coaster Enthusiasts (ACE) group will not certify a roller coaster as an ACE Coaster Classic without bench seats, among other requirements. A couple examples of roller coasters with bench seats include the Cedar Creek Mine Ride at Cedar Point and Trailblazer at Hersheypark.
