Ohio posts a maximum of 70 mph on rural interstates and expressways, a limit it adopted after years of holding at lower speeds. Most other highways outside cities and villages, including county and township roads, are capped at 55 mph, and urban business and residential districts are commonly 25 mph unless otherwise posted.

About speed limits in Ohio
Ohio's top limit is 70 mph on rural interstates and expressways, raised from the long-standing 65 mph ceiling that applied for decades. Away from those freeways, the general maximum on highways outside villages and cities, including county and township roads, is 55 mph. City freeways, urban belts and construction corridors are frequently posted lower, so the 70 mph maximum applies mainly to open rural stretches.
Ohio uses three kinds of speed rules: absolute limits, which are the posted maximum; prima facie limits, where a driver can try to show the posted speed was safe for conditions; and the basic speed law, which requires driving at a reasonable and prudent speed for existing conditions regardless of the posted number. That means a driver can be cited for going too fast for conditions even at or below the posted limit.
Urban districts, business districts and residential streets typically default to 25 mph. School zones are heavily protected, and Ohio treats speeding above 35 mph in a school zone, or above 50 mph elsewhere in a municipality, as an elevated offense; construction-zone fines can be doubled.
Ohio sharply curtailed automated enforcement. Effective July 1, 2025, House Bill 54 bans counties and townships from operating traffic-camera programs, though the Ohio constitution still lets home-rule cities and villages run cameras. The result is a patchwork where some municipalities use speed cameras and surrounding townships cannot.
Enforcement
The Ohio State Highway Patrol enforces freeways with radar, laser, marked and unmarked cruisers, and aircraft in some areas. Camera use is now split: counties and townships are banned from traffic cameras as of mid-2025, while home-rule cities and villages may still operate them.
Tolerance
As a rule of thumb, officers often do not stop drivers for less than about 5 mph over the limit, but under the basic speed law there is no guaranteed cushion and a ticket can issue for going too fast for conditions.
Speeding fines in Ohio
Most first speeding offenses are minor misdemeanors with a maximum fine around $150, though total costs commonly land between $150 and $300 once local court fees are added. Repeat offenses within a year escalate to higher-degree misdemeanors carrying larger fines and possible jail, and construction-zone fines can be doubled.
