Access Management is the process by which government agencies regulate the location and spacing of driveways, street connections, median openings, and traffic signals.
Distracted Driving Awareness
Distracted driving is any activity that could divert a person’s attention away from the primary task of driving. All distractions endanger driver, passenger, and bystander safety. These types of distractions include:
- Using a cell phone or smartphone
- Eating and drinking
- Talking to passengers
- Reading, including maps
- Using a navigation system
- Watching a video
- Adjusting a radio, CD player, or MP3 player

TEEN DRIVER SAFETY: Crashes are the leading cause of death among teens in the U.S. The Center for Disease Control and Prevention reports that drivers ages 16 to 19 are four times more likely, than older drivers, to get into an accident. Parents and other adults are being encouraged to talk to teens before they head out on the road, and also show them what it means to be a responsible driver. National studies have shown that teens usually learn their bad driving skills from, you guessed it, their parents.

FLASHING YELLOW LEFT TURN SIGNALS
Butler County’s first left-turn signals with the flashing yellow arrow (FYA) display became operational in August 2015 at Tylersville Road and Kingsgate Way / Dudley Drive. In 2020, an improvement project converted the left turn lanes on Tylersville Road at Dudley Drive/Kingsgate Way to dual left-turn lanes. Thus, the FYA display was replaced with protected only display. In 2020, ODOT converted most of the left-turn traffic signals on SR 747 to FYA operation. Click here to download an ODOT-produced brochure that fully explains this relatively new type of signal and how drivers should approach it.
FLASHING YELLOW LIGHTS – PROPER USE
When is it appropriate to install a flashing yellow light? – You may be surprised to learn that these are not necessarily a proper or safe solution in every circumstance.
Golf Carts on Public Roads
Our office occasionally receives questions and requests for golf cart usage on public roads. Golf carts are classified as a Low Speed Vehicle (LSV). Here is a summary of the rules and regulations that govern their use:
- Shall not exceed 25 MPH
- Permitted only on secondary roads with a speed limit of 35 MPH or less
- Must be equipped with headlamps, turn signals, tail lights, reflex reflectors, parking brakes, rearview mirror, windshield, seat belt (lap belt), and VIN
- Must have a title, vehicle registration, and liability insurance
- Driver must be at least 16 years old with a valid driver’s license
- Must have completed inspection from local law enforcement
- LSVs are allowed to cross a street/roadway that has posted speed limit greater than 35 MPH

Move Over to Protect Police, Fire, and EMS Personnel
Every day, America’s first responders-our police, firefighters, and EMS personnel-put their lives on the line to help protect us. When you’re out on the road, do your part to help to protect them. If you see them working on the roadside, Move Over to give them the room they need to work safely. See the complete NHTSA release by clicking here.
Text from Ohio’s Law
4511.213 Approaching stationary public safety vehicle displaying emergency light(A) The driver of a motor vehicle, upon approaching a stationary public safety vehicle, an emergency vehicle, or a road service vehicle that is displaying the appropriate visual signals by means of flashing, oscillating, or rotating lights, as prescribed in section 4513.17 of the Revised Code, shall do either of the following:
(1) If the driver of the motor vehicle is traveling on a highway that consists of at least two lanes that carry traffic in the same direction of travel as that of the driver’s motor vehicle, the driver shall proceed with due caution and, if possible and with due regard to the road, weather, and traffic conditions shall change lanes into a lane that is not adjacent to that of the stationary public safety vehicle, an emergency vehicle, or a road service vehicle.
(2) If the driver is not traveling on a highway of a type described in division (A)(1) of this section, or if the driver is traveling on a highway of that type but it is not possible to change lanes or if to do so would be unsafe, the driver shall proceed with due caution, reduce the speed of the motor vehicle, and maintain a safe speed for the road, weather, and traffic conditions.

OHIO MANUAL OF UNIFORM TRAFFIC CONTROL DEVICES and TRAFFIC ENGINEERING MANUAL
All signing, speed limits, and traffic control devices are regulated by the State of Ohio. The State has implemented these rules to provide uniformity throughout Ohio which makes driving safer for all motorists. These regulations are set forth in a 900-plus page guidebook called the Ohio Manual of Uniform Traffic Control Devices (OMUTCD).
The Traffic Engineering Manual (TEM) has been developed to assure uniformity in the application of ODOT (Ohio Department of Transportation) traffic engineering policies, guidelines, standards, and practices. The OMUTCD establishes the basic, minimum traffic control standards for all public roadways in Ohio, and all supplemental ODOT traffic engineering design, construction, and operations-related information is either contained in the TEM or referenced from it.

- Traffic Engineering Manual (Large PDF. File may take some time to download.)
The County (BCEO) does not have the legal authority to regulate parking on any street or roadway. Parking regulations fall under Township authority.
- Regulations for Vehicle Parking – Ohio Revised Code
School Traffic Safety
Speed limits are not randomly set. They are strictly determined by the State of Ohio Manual of Uniform Traffic Control Devices, per the Ohio Revised Code. Every speed limit change must be approved by the Ohio Department of Transportation (ODOT). A speed study must be performed and submitted to ODOT for approval. There are many variables that are looked at as part of the study.
SUPERSTREET INTERSECTIONS ON BYPASS 4 (COMPLETED 2012)
While the BCEO was heavily involved in the planning and coordination of this project, the Superstreets were mandated by the Ohio Department of Transportation (ODOT). For the benefit of our Butler County citizens, we prepared a brief explanation of the Superstreet concept as well as a Superstreet video demo. If after reviewing these you still have questions, please direct all inquiries to ODOT District 8.

TRAFFIC IMPACT STUDY
TRAFFIC Signals AND STREET LIGHTING
The BCEO maintains 76 traffic signals. The timing and operation of these signals are carefully observed by the Traffic Division. To report a malfunctioning BCEO maintained traffic signal, please call 513-785-4109.
Street light outages can occur from storms, accidents, and many other reasons. To help protect those in your community, first, check our Traffic Signal Maintenance List or Lighting and Pedestrian Devices Maintenance List to see if the intersection at issue is one that the BCEO maintains. If so, please report the outage here. If the street light outage is not at an intersection on our maintenance list, you can report a street light outage by contacting Duke Energy here. We appreciate your help when identifying outages.
Traffic Signals 101 – A primer for the geek in all of us. Answers questions such as ‘What are the parts of a traffic signal?’ and ‘What is signal timing?’
We are often asked why we can’t install signals at a dangerous intersection to make it safer. It isn’t that simple. Like speed limits, there are strict guidelines set forth by the State of Ohio that govern the use of traffic signals.
Work Zone Awareness
The summer months bring lots of road construction in Butler County and across the nation. This is a perfect time to brush up on Work Zone Awareness.
As the number of workers on the road rises, the risk of crashes and fatalities also increases. 80-85 percent of victims in work zone crashes are passengers and drivers and 10-15 percent are workers.
We all must work together to ensure highway crews and drivers on the road get home safely. Sign our pledge to slow down when you see orange. Even one death is too many.
SEE ORANGE, SLOW DOWN
When approaching a work zone:
- Slow down
- Keep a safe distance between me and the car ahead
- Pay attention to signs and obey road crew flaggers
- Stay alert and expect the unexpected
- Never use a cell phone
- Be patient
