Imagine driving through your neighborhood and noticing that a familiar four-lane road has become a three-lane street overnight. While the change may seem counterintuitive, understanding how these improve road safety can provide helpful context if questions arise after a crash on a redesigned roadway.
The logic behind road diets
A classic road diet changes a four-lane undivided road into a lane separated by a center two-way left-turn lane. Depending on the area’s needs, city planners can then use the extra road space for bike lanes, on-street parking, or pedestrian refuge islands.
Four-lane undivided roads can create safety concerns because both through traffic and vehicles slowing to make left turns use the inside lane. This increases the chances of rear-end, sideswipe and angle crashes. The Federal Highway Administration considers road diets a proven safety measure, with studies showing crash reductions of 19% to 47% on converted roads.
Not every road is a good candidate for this type of redesign. Engineers generally use road diets on streets that carry fewer than about 20,000 vehicles each day. Because many projects require little more than repainting lane markings during scheduled resurfacing, they can often improve safety without major public expense.
Safety features in these projects
Ohio conversions rarely stop at new lane lines. Cities tend to bundle several complementary elements into a single project, such as:
- A center turn lane that shelters vehicles waiting to cross oncoming movement
- Marked bike lanes that separate riders from motorized traffic
- Pedestrian refuge islands that let walkers cross one direction at a time
- High-visibility crosswalks and upgraded signals at busier intersections
- Curb extensions that shorten crossing distances and improve sightlines
These features do more than improve safety. They also establish how drivers, cyclists and pedestrians are expected to use the roadway. If a crash occurs, these additions may become one factor considered when determining how the incident happened.
Liability after a crash on a redesigned road
A redesigned street does not change Ohio’s fault rules, but it can affect how those rules apply after a crash. The state follows a modified comparative fault system, which means a court reduces your compensation in proportion to your share of responsibility for the collision. If your share reaches 51%, you typically cannot recover damages at all.
The state generally gives injured people two years to file most personal injury claims. The same timeline often applies even when a government entity may be involved.
Claims against a government entity, however, can be more complex than those against a private driver. State law provides cities and other public bodies with certain legal protections, meaning you must generally show that an exception to governmental immunity applies before your claim moves forward. Seeking legal guidance can help you with preserving evidence related to your injury and navigating the claims process.
