Frequently Asked Questions

Q. What is the recommended shape of a construction sign?


Road construction signs are diamond-shaped (square with one diagonal vertical). There are three types of road signs - regulatory, warning, and guide signs. Out of these, warning signs are diamond-shaped (MUTCD Section 2A.09). Since construction work signs are a kind of warning for oncoming traffic, these are in diamond-shape. A distinct shape ensures that roadway users understand the sign category and type of information displayed on the sign. Such as in heavy fog, you may be able to make out only the shape of a sign.

Q. What is the color of construction signs - yellow or orange?


There are two types of road warnings - temporary and permanent. Temporary warnings, typically due to construction, are in orange with black text (MUTCD Section 6F.02), while permanent warnings are in yellow for maximum readability and visibility. Orange has been widely used in road construction signs and other traffic control devices like cones, barrels, and delineators. In road construction, orange acts as an indicator for a driver because it is associated with roadside work. Fluorescent versions of orange may also be used.

Q. How do ConeBoss Road Construction Signs work?


Made of rigid, 3/16” thick plastic, our revolutionary ConeBoss Signs help you convert a traffic cone into a signpost. Injection-molded Cone Sign for construction fits snuggly over most common size traffic cones. No need to pinch the cone to apply the sign. If you want to install the ConeBoss Sign permanently on the cone, just screw the sign into the cone using the two little holes provided. This would also ensure the signs remain more stable in winds.

Q. How big should road construction signs be? What is the largest size you offer?


The recommended size for all Temporary Traffic Control signs which include road construction signage, construction traffic signs, road construction, and maintenance area signs, or highway construction and maintenance signs shall be referred from Table 6F-1 of MUTCD. The largest size we offer for our diamond-shaped road construction sign is 36” x 36”. The largest vertical sign measures 48” x 36”. 

Diamond-shaped road construction signs are typically 48"x48" for freeways and expressways, 36” x 36” and 24” x 24” for conventional roads. The minimum required dimension for most diamond-shaped TTC signs is 30” x 30”.

Q. How can I customize a Road Construction Sign without having any knowledge of designing?


Just look for a “Custom” flag on the top right corner of the listings. On the product page, you will see customization boxes where you can enter your text. This can be a construction traffic message, highway maintenance message, or any other text. There are options to alter letter size for your custom wording. You can increase or decrease the letter height with two buttons given next to the customization boxes. It’s easy to adjust the font type and alignment of your text too. All this doesn’t require any expertise in designing. Our customization tool is very user-friendly. On the final page after material selection, you can check the box, “Yes, I’d like your professional artists to tweak my design at no extra charges,” in case you are not satisfied with your custom design. You can also send any special instructions about your order in this step.

Q. Are your road construction signs retroreflective?

Yes, all our road construction signs are retroreflective. You can choose between 3M Engineer Grade Reflective Aluminum, 3M Hi-Intensity Reflective Aluminum, 3M Diamond Grade Reflective Aluminum, or 3M Diamond Grade Fluorescent Orange. The reflective sheeting meets DOT specifications for Roads and Bridges on Federal Highway Projects FP-85 for Sheeting Type II, Class 1 or 2.

Q. Can I return my order if I am not satisfied with the quality? Do you have a return policy?
