One Way Signs

One Way Signs FAQ

What are One Way Signs?

One Way Signs inform motorists that traffic on a street travels in one direction only. There are two subcategories: One Way Arrow Signs (R6-1L, R6-1R, R6-2L, R6-2R, R6-2S) and text-only Begin One Way (R6-6) and End One Way (R6-7) signs.

What are some common applications for One Way Signs?

One Way Signs help navigate downtown roads, manage traffic flow at schools, and reinforce messaging at roundabouts. They should be mounted parallel to the one-way street and at every entrance onto it, including alleyways and parking lots (MUTCD 2B.49).

Where should One Way Signs be installed?

At unsignalized intersections, two One Way Signs are used - one at the near right of the approaching road and one at the far left across the one-way road. At unsignalized T-intersections, one is placed on the far side across the one-way street and another at the near right. At signalized intersections they may be mounted overhead or per the unsignalized guidance (MUTCD 2B.49).

What do One Way Signs look like?

The R6-1L and R6-1R signs have a black background with a white border and a white horizontal arrow that encloses the words One Way in black. The R6-2L, R6-2R, and R6-2S signs are white with a black border, with One and Way on separate lines and a left, right, or up arrow below. R6-6 reads Begin One Way and R6-7 reads End One Way.

What other signs are used with One Way Signs?

No Left Turn (R3-2), No Right Turn (R3-1), and No Straight Through (R3-27) signs warn drivers that traffic will flow toward them. A One Way arrow sign is also used with a Stop sign and a Divided Highway sign at approaches to a divided highway, and an Except Bicycles plaque (R3-7bP) can be added where bicycles may travel in both directions.

What size One Way sign should I choose?

Per MUTCD Table 2B-1: R6-1L and R6-1R are 36x12 inches on single-lane roads and 48x18 on multi-lane roads, highways, and interstates. R6-2L, R6-2R, R6-2S, R6-6, and R6-7 are 24x30 on single-lane roads, 30x36 on multi-lane roads and highways, and 36x48 or 48x60 on interstates.

Do I need a Begin/End One Way Sign?

Begin and End One Way signs are optional. The MUTCD notes that they may be used, and the decision is left to state and local traffic authorities (2B.49).

What are One Way Signs mounted onto?

For ground installation, mount One Way Signs on a round, square, or U-channel post with sign mounting hardware. 36x48 and 48x18 signs are pre-drilled with four holes for a two-post installation; other sizes have two holes for a one-post installation. For overhead installation, use overhead sign brackets on traffic-signal poles and spans.

What is the mounting height for One Way Signs?

On the central island of a roundabout, the minimum mounting height is 4 feet from the bottom of the sign to the roadway (2B.49). Otherwise the MUTCD does not specify an exact height, leaving it to local traffic authorities and engineering judgment.
