Speed Limit Signs

Durable, bold speed limit signs

Signs for posting speed limits have to be sturdy and highly visible, like other safety supplies for commercial applications. Most commercial speed signs consist of .040, .063, or .080-gauge aluminum that is UV and corrosion resistant and withstands temperature extremes from -30 to 200 degrees Fahrenheit. Options range in size from 18 x 12 inches to 24 x 18 inches, with bold, black markings on a white background.

All choices have highly reflective surfaces. For slower traffic, go with engineer-grade surfaces that consist of impregnated glass beads or prismatic optical sheeting bonded to aluminum. For faster-moving vehicles, choose aluminum-bonded, high-intensity prismatic optical sheeting. Each provides the appropriate bounce-back reflectivity from headlights at night, dawn, and dusk, as well as nonglare reflectivity during daylight hours.

The signs have different applications

Commercial establishments and privately owned facilities and residential areas all need speed limit signs for traffic discipline when the public has access to roads that are also open to heavy foot traffic. Some of the types of roadways where these notices are necessary include the following:

• Ring roads around commercial areas like supermarkets or mini malls
• Circulation streets that connect larger arterial roads to local streets in gated subdivisions
• Driveway lanes in and around parking lot spaces.

Speed postings are also among many private property signs that are useful for driveways and parking areas in apartment complexes, office parks, or industrial complexes. The speed notices are an ideal accompaniment for other traffic signs and cones that direct vehicles safely around private areas, also working in conjunction with other posts like "No Parking" or "Fire Lane," for an entire private property safety warning system.

Commercial speed signs offer a range of limits

Traffic in and out of commercial premises and private property has to be restricted to certain speeds depending on where motorists are driving. Speed limit signs for private applications include 5, 10, 15, 25, and 30 mph. The lower speeds are appropriate for road access in front of stores, office buildings, and apartment complexes with heavy pedestrian traffic. The higher limits are appropriate for long entryways into private complexes to sustain the flow of vehicles. Industrial complexes may need a variety of speed options as part of their traffic safety management system for pedestrian and car traffic, as well as parking access.
