Speed Limit Signs

Q: Fluorescent, reflective, or non-reflective - which Speed Limit Signs have the best performance?

If you&rsquo;re looking out for daytime visibility, standard non-reflective aluminum signs will work just right. Reflective signs are a step up and offer greater visibility at nighttime. <a href="https://www.roadtrafficsigns.com/speed-limit-signs">Reflective Speed Limit Signs</a> come in three grades - Engineer Grade, High Intensity, and Diamond Grade. Retroreflective signs return light to its source. Almost all of the light striking at the sign&rsquo;s surface from the vehicle's headlights is reflected back to the driver&rsquo;s eyes. The best reflectivity, however, comes from fluorescent speed limit signs that combine the high conspicuity of fluorescent colors with great nighttime reflectivity and the wide-angle performance of 3M micro prismatic lens technology.

Q: What does “3M's 10-year warranty” exactly mean?

With &ldquo;3Ms 10-year warranty&rdquo;, we mean that all our aluminum and reflective aluminum signs will be free from defects in materials and workmanship for ten years from the date of purchase.

Q. Fluorescent, reflective, or non-reflective - which Speed Limit Signs have the best performance?

If you’re looking out for daytime visibility, standard non-reflective aluminum signs will work just right. Reflective signs are a step up and offer greater visibility at nighttime. Reflective Speed Limit Signs come in three grades - Engineer Grade, High Intensity, and Diamond Grade. Retroreflective signs return light to its source. Almost all of the light striking at the sign’s surface from the vehicle's headlights is reflected back to the driver’s eyes. The best reflectivity, however, comes from fluorescent speed limit signs that combine the high conspicuity of fluorescent colors with great nighttime reflectivity and the wide-angle performance of 3M micro prismatic lens technology.

Q. Do you offer discounts on bulk quantity orders?

Yes. Quantity discount is an incentive we offer that results in a decreased cost per unit of goods or materials when purchased in greater numbers. However, all items must be of the same design, size, material, color, and print.

Q. How can I add a black arrow on a custom Speed Limit Sign?

Just leave the instructions like adding a left-pointing, black colored arrow, or an additional line to your custom sign-in that box. Our team will send the proof to you for your approval.

Q. I want to install a Speed Limit 20 Sign outside my driveway. Is it legal to do that?

The best course of action is to contact your traffic law enforcement agency or your state’s DOT to know the legality of installing speed limit signs outside your driveway. First, it should be confirmed whether the street outside your driveway is state-owned or maintained by an HOA or road maintenance organization. Speed limits on “roads open to public travel” are controlled by general statutes and local and state ordinances and you should confirm with the person(s) in charge.

Q. I live in Connecticut. Which Speed Limit Sign should I buy?

In Connecticut, the official speed limit is 65 MPH for rural interstates and other limited-access roads. For urban interstates and other roads, the speed limit is 55 MPH. Have a look at our 55 MPH signs. Use our Custom Speed Limit Signs which can be printed with any speed limit value.

Speed Limit 20 : Speed Limit 20 MPH Part #:X-R2-1-20 18" x 12" Engineer Grade Reflective Aluminum Sign Verified Purchase

Great sign, steep shipping charge.

The sign is perfect. It was easy to order and arrived swiftly. However, the shipping charges (even for "standard" shipping) were outrageous.

RoadTrafficSigns: We're sorry that the shipping price was too much. We appreciate your feedback on this order greatly. The items on our RoadTrafficSigns are heavily discounted, for this reason we're unable to provide free shipping on this website.

MUTCD Compliant Speed Limit Sign : Speed Limit 25 Part #:X-R2-1-25 24" x 18" Engineer Grade Reflective Aluminum Sign, 80 mil Verified Purchase

There was no limit

Since there was no 25mph sign on my 25mph street, some drivers assumed that there was no limit. I'm hoping this helps.
