Drivers are not allowed to use the center lane of such a highway for passing slow-moving vehicles, except when funding or space constraints dictate use of it as a rush hour "travel lane" when traffic is largely asymmetric between a central business district and its suburbs. [4] However, some studies have found that converting high-speed four lane streets into three lane streets (one lane of traffic in each direction with a center turn lane) and lowering speed limits can result in improved safety, despite the use of a center turn lane, as traffic collisions occur at far lower speeds.[5].
