Speed Bump Ahead Signs

Yes. Type a short extra line, such as a lot name or a building number, and the live preview shows the finished sign as you type. Look at the preview before you order to make sure the line is easy to read from a car.

Aluminum (.040 in) is rigid and rust-free, and it takes 1/4 in holes at the corners or top for screws or bolts to a post. Plastic is a light, flexible .020 in styrene with brass grommets, which suits a sign you move or zip tie to a temporary post. Pick aluminum for a permanent mount.

You can type the number on the extra line, and the preview shows it before you order. The printed words stay the same, so the sign still reads as a warning about the bump first. A posted speed limit usually falls under your local road authority, so check your state and local rules before you put a number on a sign.

Yes. Reflective aluminum uses reflective vinyl on .040 aluminum, so it shines back when headlights reach it at night. That makes it the better choice for a dark lot or a rural lane with no streetlight. The regular aluminum version still reads well in daylight.
