Factors to Consider Before Buying Traffic Signs

While it may seem like a simple process, buying traffic signs can be quite challenging. You search for what you want, you compare prices, and you order. But choosing the right signs takes a little more thought, especially when road users’ safety depends on seeing and understanding them in time. 

The right sign should be appropriate to the site, visible under all weather conditions, and comply with the standards applicable to the project. From managing a construction job site to upkeep and management of private roads and equipment for a public works project, a few practical checks can help you make a smarter investment. 

Identify the Purpose of Each Sign 

Before comparing products, decide the message you want the sign to convey. Is it warning drivers of a hazard, providing guidance on traffic lanes to avoid road work, posting a speed limit, or defining a restricted area? There are different messages and sign types for different situations.

Traffic signs are selected and used according to the sign’s purpose to avoid confusion. For example, a warning sign must be used to identify a possible hazard, and a regulatory sign to convey a rule or restriction. The message should be easy to recognize and appropriate for the location.

Check Local Standards and Requirements

Compliance should be the top priority on your buying list. The design, size, color, symbol, and placement of traffic signs may differ by jurisdiction and depending on whether the road is public or private. For public roads and work zones, check the applicable traffic control standards and consult the relevant road authority when necessary. 

Don’t assume that a sign is compliant simply because it looks familiar. Ensure that its purpose, size, and design are suitable for your project. This is important to get right before buying, to prevent replacement costs and installation delays. 

Consider Visibility and Reflectivity 

There’s no point in having a sign if no one sees it in time to respond. Conditions such as lighting, speed of traffic, obstructions on the roadside, and weather may impact visibility. A sign that is not clear may not be noticed after dark or on a rainy day.

Reflective materials can help to improve visibility at night by reflecting light from the headlights of a vehicle back to the driver. Take into account the size and distance from which the sign will be read. 

Generally, a greater time margin is required for higher speed drivers to read a message and safely respond. Even if the words are right, selecting a sign that is too small for its setting can undermine its purpose.

Choose Durable Materials for the Environment 

Outdoor signage needs to be able to handle more than just a dribble of rain. Depending on the location, they may face intense sunlight, strong winds, temperature changes, moisture, dust, and everyday wear. Be aware of the type of materials and finishes that will be used for the sign to fit the environment in which it will be placed. 

Different signs and mounting systems for different sites can be required to withstand frequent use, whereas different materials may be needed for permanent installations to endure outdoor conditions. Inquire with suppliers regarding materials specifications, service life, maintenance requirements, and availability of replacement parts.
