Keep Right & Keep Left Signs FAQ
Who uses these signs?
City planners and highway contractors use these signs to direct traffic flow on public roads and highways.
Where are Keep Right Signs commonly used?
Keep Right Symbol Signs are commonly used in pairs. On two-lane roads that have opposite traffic flows, one Keep Right Symbol Sign is placed at each end of the median.
Where do you commonly see Keep Left Signs?
Divided highways often have obstructions in the median that are intended to guide drivers through each turning lane. A driver turning left onto a divided highway may see a Keep Left Sign in the highway median. The sign points upwards and to the left, which is the exact direction where the driver should continue.
Are there any supporting placards for Keep Right/Left Signs?
Because Keep Right/Left Signs contain all the information a driver needs, these signs do not have supporting placards.
Can Object Markers be used with Keep Right/Left Signs?
The MUTCD does not provide specific guidance on using Object Markers and Keep Right/Left Signs together. However, Object Markers and Keep Right Symbol Signs have overlapping uses. Section 2C.71 of the MUTCD mentions that any obstruction within the roadway, including medians, can be marked with either a Type 1 or a Type 3 Object Marker.
What size Keep Right/Left Sign should I choose?
According to Section 2B, Table 2B-1 of the MUTCD, choosing the correct Keep Right/Left Sign mainly depends on roadway type and speed. 24x30 signs are used on single- and multi-lane roads and highways. 36x48 (expressway) and 48x60 (freeway) signs are the minimum sizes for interstates. The federal minimum is 18x24, suited for low-volume roads. 36x48 signs are considered oversized and are often used for interstate and large roadways.
What is the difference between standard and narrow Keep Right/Left Symbol Signs?
Aside from the difference in sign size, the primary difference is where the signs can be mounted. 18x30-inch narrow signs can only be used in medians less than 4 feet wide. Standard symbol signs are used in all other relevant circumstances.
What materials are used to create Keep Right/Left Signs?
All of our rigid signs are manufactured with rust-proof .080-inch aluminum, and sign information is printed onto your choice of high-intensity prismatic or full-cube prismatic sheeting.
How are Keep Right/Left Signs packaged for shipping?
Signs arrive in boxes cut to size to minimize movement during shipment. We also cover the face of each sign with slip sheeting to protect signs from shipping damage.
What MUTCD section contains more information?
Section 2B.39, Keep Right and Keep Left Signs (R4-7 Series and R4-8 Series), in Chapter 2B of the MUTCD has more information about Keep Right/Left Sign selection, how signs should be placed, and when to use which sign.
