White road signs communicate many of the rules drivers follow each day, including speed limits, lane movements, parking restrictions, and pedestrian right-of-way. Our white-background selection brings together speed limit signs and plaques, lane control signs, parking notices, and pedestrian regulatory signs on .080" reflective aluminum, with legend colors matched to each design.

What Does a White Road Sign Mean?
White is the MUTCD regulatory color. A white sign with a black legend gives an order that carries the force of law: the speed limit, which way traffic flows, which lane must turn, where you may not park, where you must stop for a pedestrian. When the order is a prohibition, the legend adds red: a red circle and slash over a symbol, or red lettering as on Do Not Enter and Wrong Way. White is also used for a few guide plaques, such as the black-on-white route arrows that mount under a route marker, and for the crossbuck at a railroad crossing.
Because white means a rule, a white sign has to be exact. The MUTCD sets the wording, the letter series, the border, and the size for each one, and an agency will not accept a rule sign that departs from them. Every white sign in this category follows the standard drawing for its code.
Which White Sign Do You Need?
Start with the rule you need to post, then pick the sign that states it. Each row links to the sub-category with every size and arrow version.

| Rule to post | Signs to use | MUTCD codes |
|---|---|---|
| The speed limit, or a truck, bus, night, or minimum speed | Speed Limit Signs and Regulatory Speed Limit Signs with R2 plaques | R2-1, R2-2P, R2-2aP, R2-3P, R2-5a, R2-6P |
| A turn, U-turn, or through movement is not allowed | Turn Signs and No Signs | R3-1, R3-2, R3-3, R3-4, R3-18, R3-27 |
| A lane must turn, go straight, or is reserved | Lane Control Signs with HOV, bus, and taxi lane plaques | R3-5, R3-7, R3-5bP to R3-5gP |
| Keep right, stay in lane, do not pass | Keep Right, Stay in Lane, Do Not Pass in Regulatory Signs | R4-1, R4-7a, R4-8a, R4-9 |
| Trucks, through traffic, or bicycles are excluded | Truck Signs, No Thru Traffic, Authorized Vehicles Only, Bicycle Signs | R5-2, R5-2b, R5-11, R5-12, R5-6, R5-1b |
| Traffic flows one direction | One Way Signs | R6-1, R6-2 |
| Parking is restricted or reserved | No Parking Signs, Reserved Parking Signs | R7-1, R8-3, R8-3a, R7-8 |
| Drivers must stop or yield for pedestrians | Pedestrian Signs: Stop Here, Yield Here, State Law crosswalk signs | R1-5, R1-5b, R1-6, R9-3bP |
| The road, street, or bridge is closed | Road Closed Signs | R11-2, R11-2a |
| Railroad crossing rules | Railroad Crossing Signs: crossbuck, Do Not Stop on Tracks | R15-1, R8-8 |
| Direction arrows under a route marker | Arrow Signs | M5-1, M5-2, M6-1 to M6-7 |
Arrow direction matters on parking, one way, and lane signs. Order the arrow that points along the curb or lane the rule applies to, as the driver sees it.
What Size White Sign Do I Need?
MUTCD Table 2B-1 sets a standard size for every regulatory sign on conventional roads and a larger size for expressways and freeways. These are the ones we ship most.
Scroll sideways to view the full table on smaller screens.
| Sign | MUTCD code | Conventional road | Expressway and freeway |
|---|---|---|---|
| Speed Limit | R2-1 | 24" x 30" | 36" x 48" and 48" x 60" |
| Truck, bus, night speed plaques | R2-2P, R2-2aP, R2-3P | 24" x 30" | 36" x 48" |
| No Left Turn, No U-Turn, No Turns | R3-2, R3-4, R3-3 | 24" x 24" | 30" x 30" and 36" x 36" |
| Lane Must Turn | R3-7 | 30" x 30" | 36" x 36" |
| One Way, horizontal | R6-1 | 36" x 12" | 54" x 18" |
| No Parking, Reserved Parking | R7-1, R8-3a, R7-8 | 12" x 18" | Not used |
| Do Not Pass, Keep Right | R4-1, R4-7 | 24" x 30" | 36" x 48" |
| Yield Here to Pedestrians | R1-5 | 36" x 36" | Not used |
| Road Closed | R11-2 | 48" x 30" | 48" x 30" |
A larger sign is always allowed. A smaller one is allowed only on private property and parking areas where the MUTCD does not apply. If you are replacing a sign, measure the old one and match its code.
Which Reflective Sheeting Should You Order?
- High Intensity Prismatic (HIP) meets ASTM Type IV and the MUTCD minimum retroreflectivity for white regulatory signs. It is the standard order for city streets, county roads, parking lots, and private property.
- Diamond Grade DG3 meets ASTM Type XI and returns about twice the light of HIP. Choose it for high-speed roads, overhead or left-side mounting, and any contract that specifies Type XI.
Regulatory signs have the highest minimum retroreflectivity levels in the MUTCD because a driver has to read the words, not just see the shape. When in doubt on a road posted 45 mph or more, order DG3.
Mounting a White Regulatory Sign
Vertical signs such as Speed Limit and No Parking are drilled on the centerline for a single U-channel or square post. Wide signs such as One Way and Road Closed take two posts. Mount the bottom of the sign at least 7 feet above the pavement where pedestrians walk and 5 feet in rural areas, and place a regulatory sign at the point where the rule begins, not in advance of it. Posts, brackets, and bolts are in our Sign Posts category.

White Road Sign FAQ
Is a white sign enforceable on private property?
Speed limits and parking rules on private property are enforced by the property owner, not by police, unless a local ordinance adopts them. Using the standard MUTCD sign still matters because drivers obey a sign they recognize. Many cities also require MUTCD signs in private parking lots for accessible parking and fire lanes.
Why is Do Not Enter red if white means regulatory?
It is still a regulatory sign. The MUTCD adds red to a white regulatory sign when the order is a prohibition, which is why Do Not Enter, Wrong Way, and the circle-and-slash symbol signs are in both our White Signs and Red Signs categories.
Can I add my own wording to a white sign?
Yes, for private property. Our custom signs let you type your own rule, and we will print it on the same aluminum and sheeting as our stock signs. For a public road, use the standard MUTCD design when one exists.
How long does a white sign last?
White fades the least of any sign color, and a white sign on HIP sheeting typically stays above the MUTCD minimum for 10 to 12 years. The legend and border are what fail first, so inspect at night for a legend that has gone gray against the background.
