New Traffic Signals to be Installed in Vincennes

Flashing yellow left turns begin Monday at U.S. 41 & Wheatland Rd

VINCENNES – The Indiana Department of Transportation (INDOT) announces improvements will be made to traffic signals in Vincennes and other locations throughout the area.


Beginning Monday, November 18, INDOT crews will begin installing new left-turn signals at U.S. 41 and Old Wheatland Road that will provide a flashing yellow arrow. This allows left-turning traffic to yield the right-of-way to oncoming traffic and pedestrians and turn when a suitable gap is available. Previously drivers have only been able to turn left at this intersection with a protected green arrow.

National research has shown that the flashing yellow signal is more intuitive for drivers, results in fewer crashes and moves traffic more efficiently. The signals are being introduced nationwide and have been adopted by most states, including neighboring Ohio.

A flashing yellow arrow for left turns at an intersection means that motorists should slow down and use caution when turning, and must yield the right-of-way to oncoming traffic as well as any pedestrians who may be crossing the intersection.

The steady yellow left-turn arrow retains its standard meaning that the signal is about to change to a steady red arrow and drivers should prepare to stop or, if they have already entered the intersection, complete the left turn. These types of signals are only used on intersection approaches with dedicated left-turn lanes, which clears the way for through and right-turning traffic.

In addition to converting certain locations like U.S. 41 and Wheatland Road, INDOT plans to replace most of its five-section or “doghouse” left-turn signals with the new four-section signals featuring a flashing yellow arrow. Other locations within the Vincennes District that will be replaced this winter include U.S. 50 and the ramps at Interstate 69 east of Washington and in Princeton on S.R. 64 at 5th Avenue, Richland Creek Drive and Wal-Mart plaza.

INDOT’s successes in reducing congestion on heavily traveled highways are featured in its award-winning Indiana Mobility Report, jointly published with Purdue University. The report ranks congestion on Indiana’s interstates, including increases or reductions in travel time. Since 2011, congestion on Indiana’s interstate system was reduced by 6 to 18 percent, with most occurrences of significant congestion attributable to construction, severe weather and nonrecurring incidents. Innovative mobility performance measures are used as planning tools to help INDOT and policymakers shape future infrastructure investment priorities.

More information about the flashing yellow left-turn arrow is available on INDOT’s web site at
