Background
On December 20, 2024, Samba Diallo’s vehicle struck M.A., a construction worker assigned as a flagger on Anthony Wayne Avenue in Lockland, Ohio. M.A. was standing in the roadway wearing a reflective vest and hard hat, holding a large “STOP” sign, and was surrounded by orange construction cones. The vehicle hit her despite her being clearly visible for over 20 seconds as Diallo drove down a straight road. Diallo’s windshield appeared fogged or obstructed at the time of impact. M.A. suffered serious injuries—a fractured tibia and fractured fibula in her left leg—requiring eight weeks of boot treatment.
Diallo was initially issued a traffic citation for violating Village of Lockland Ordinance 432.38 (“Weaving; Full Time and Attention”). He was subsequently indicted on two counts of vehicular assault under R.C. 2903.08(A)(2), charged with recklessly operating a vehicle in a construction zone (Count 1) and recklessly operating a vehicle (Count 2), both felonies of the fourth degree. Before trial, Diallo filed a motion to dismiss based on double jeopardy, arguing that his prior conviction for the traffic ordinance violated barred the vehicular assault prosecution for the same incident. The trial court denied the motion.
At trial, the State presented evidence including dash-camera footage of the incident, witness testimony from construction workers and the responding police officer, and medical records documenting M.A.’s injuries. Diallo did not dispute that he operated the vehicle or that M.A. suffered serious physical harm; the dispute centered on whether his conduct constituted recklessness. The trial court convicted him of Count 2 vehicular assault (the State voluntarily dismissed Count 1), and Diallo appealed, raising three assignments of error.
The Court’s Holding
The appellate court affirmed Diallo’s conviction, holding that sufficient evidence supported a finding of recklessness. Under R.C. 2901.22(C), recklessness requires acting with “heedless indifference to the consequences” while disregarding “a substantial and unjustifiable risk” of causing harm. The court found the dash-camera footage particularly persuasive: it showed Diallo driving toward M.A. for more than 20 seconds on a straight, unobstructed road. During that time, M.A. remained plainly visible in the street with a large “STOP” sign, a brightly colored reflective vest, a hard hat, and surrounded by orange traffic cones. Despite these warnings and ample time to observe her presence, Diallo did not slow down or attempt to avoid her. The court rejected Diallo’s argument that a fogged windshield meant he could not see her, noting that failing to see a flagging worker for 20 seconds in a clearly marked construction zone reflects heedless indifference rather than mere negligence.
On the manifest weight of the evidence challenge, the court applied the “thirteenth juror” standard and found the trial court’s verdict was not a manifest miscarriage of justice. The evidence of Diallo’s extreme inattention and disregard for the obvious risks in the construction zone was clear and substantial. Regarding the double jeopardy claim, the court applied the Blockburger test: an offense bars a successive prosecution only if both offenses are the same—that is, each requires proof of a fact the other does not. Vehicular assault requires proof of serious physical harm and recklessness; Lockland Ordinance 432.38 (weaving without full time and attention) requires neither. Because the offenses contain materially different elements, the vehicular assault prosecution did not violate double jeopardy protections.
Key Takeaways
- A driver acts recklessly for vehicular assault purposes when driving with heedless indifference toward visible hazards and failing to take evasive action despite ample time and clear warnings in a construction zone.
- A prior traffic-ordinance conviction for the same incident does not bar a subsequent vehicular assault prosecution under the double jeopardy clause when the offenses require proof of different elements (serious physical harm and recklessness vs. traffic infraction).
- Dash-camera footage and construction-zone safety protocols (reflective vests, “STOP” signs, traffic cones) can establish recklessness when a driver strikes a plainly visible worker despite adequate time to observe and avoid.
- Difficulty seeing the road due to a fogged windshield does not negate recklessness; rather, driving with obstructed vision in a marked construction zone compounds the recklessness finding.
Why It Matters
This decision reinforces that vehicular assault convictions in construction zones do not require proof that the driver intentionally or knowingly caused harm—recklessness suffices. The court’s emphasis on the 20-second period during which M.A. was visible and the abundance of warnings (large sign, reflective vest, hard hat, orange cones) establishes a fact-intensive standard: drivers must exercise reasonable care to avoid plainly marked hazards, and failing to do so while maintaining speed demonstrates the heedless indifference required for recklessness. The decision also clarifies that construction-zone safety protocols are powerful evidence of recklessness when disregarded.
The double jeopardy holding is significant for prosecutors: a traffic citation for an unsafe operation does not shield a defendant from a subsequent, more serious vehicular assault charge arising from the same incident, provided the assault charge requires elements (like serious physical harm or recklessness) that the traffic ordinance does not. This allows prosecutors to seek proportionate charges based on injury outcomes while avoiding double jeopardy concerns, provided they can prove the enhanced mens rea and injury requirements.
