Scott County flags intersection risks and growing e‑bike safety gaps
Summary
County traffic and safety staff said pedestrians and motorcycles are overrepresented in local crashes, enforcement has declined since 2020, and e-bikes present regulatory, enforcement and battery-fire challenges that statutes and outreach have not yet resolved.
Scott County transportation and safety staff told commissioners that intersections and certain user groups drive a disproportionate share of fatal and serious-injury crashes and that countermeasures beyond signals are being pursued.
Mark Callahan, Scott County’s traffic engineer, said staff have seen pedestrian crashes as a priority and that motorcycle crashes appear overrepresented locally compared with statewide figures. He described standard engineering responses — improved signing, pavement markings, signal timing and, where patterns warrant it, converting problematic intersections to roundabouts or three-quarter intersections. "If we notice people are running red lights, we could extend signal timing for an all-red phase," Callahan said as one tool to reduce conflict.
Panelists also raised a concern about enforcement capacity. Emergency-management and law-enforcement representatives said traffic enforcement has been lower since about 2020 and argued this reduction correlates with more distracted driving on county roads. "Enforcement's been down since about 2020," one presenter said, noting that increased, prioritized enforcement historically reduced DWI fatalities.
The briefing dedicated significant discussion to e-bikes and similar devices. Staff reported a rapid proliferation of e-bikes and e-scooters, confusion over whether devices are bicycles or motor vehicles and a related enforcement gap: many devices being used by juveniles lack the pedals that would classify them as pedal-assist bicycles and instead resemble motorized vehicles that require licensing. Staff warned of a separate safety and environmental risk from lithium batteries: "[E-bikes] are high risk from a traffic concern. They're also a huge risk on the fire side because of the batteries," a panelist said. County staff recommended stepped actions: coordinated county and city messaging, targeted education for parents and youth, and continued engineering and enforcement interventions; a November highway-safety briefing is expected to share further analysis on pedestrians and e-bikes.
