Sign Information

You need quality, appropriately reflective, street name signs? You have come to the right place. Without road name signs it would be much more difficult to find that avenue your aunt moved onto last spring. Clearly marked roads are a wonderful convenience for drivers, but they are crucial for emergency services.

Did you know you can make your own street sign? Customized street signs from Traffic Sign Pro adhere strictly to regulations. You’ll want to ensure you select the correct sign features for your specific usage.


Quick Facts:

  • SIZE OF LETTERING. Did you know that traffic speed determines the height measurement of lettering on road name signs? According to the current MUTCD, lettering should typically be 6” in height. On low-volume and urban roads where speed limits are 25 MPH or less, 4” letters may be used. According to the SHSM book, the general rule of thumb is to have 1” of letter height for every 40 feet of desired legibility. This means that the average driver will not be able to read a 4” street name until he is about 160’ from it. Driving at 35 MPH, a vehicle travels over 50’ per second. This means that a driver has only about 3 seconds to read the sign and make the decision to turn. In poor visibility conditions like night, fog, or rain, this time is reduced even further.
  • REFLECTIVITY. The FHWA has standards of reflectivity that must be met or exceeded. Be sure to select the right grade for your application. Our engineer-grade reflective sheeting meets the ASTM D4956 type I specification and has an average life span of 7 years. Our engineer-grade prismatic reflective sheeting exceeds the ASTM D4956 type I specification and also has an average life span of 7 years. Our high-intensity prismatic reflective sheeting is 3 times more reflective than the engineer grades, meets MUTCD prismatic sheeting type III specifications, and has an average life span of 10 years.
  • TYPE. Our street name signs also come in flat or extruded rustproof aluminum. Both are made of .080 gauge aluminum which will stand up to more abuse than thinner types. The flat aluminum street signs are flat blades with rounded corners to prevent injuries. The extruded aluminum street signs have square corners and are corrugated on top and bottom. This helps to prevent damage from winds associated with violent storms.

Our signs are manufactured in accordance with the U.S. Department of Transportation (DOT), Federal Highway Administration (FHWA), Manual on Uniform Traffic Control Devices (MUTCD), and Standard Highway Signs and Markings (SHSM) book. All types of our retroreflective sheeting are manufactured in accordance with the American Society of Testing and Materials (ASTM) D4956—Standard Specification for Retroreflective Sheeting for Traffic Control.

Road work! Right Lane Closed! Slow Down to a Crawl Next 100 Miles! No one likes to see these construction signs on their route, but no one likes driving on bad roads, either. When it comes to road construction and construction traffic signs the main concern is SAFETY. And we all know that when it comes to safety, the government has no shortage of regulations. So what do you need to consider when it comes to purchasing orange and black construction road signs? You want durable signs that meet or exceed state and federal regulations in size and particularly retroreflectivity.


Quick Facts:

  • DURABILITY & QUALITY. Every sign that you purchase from is cut from a more durable .080 gauge, rustproof aluminum that resists fading from direct sunlight for several years.
  • SIZE. Most of the construction signs in this category are considered “temporary traffic control” signs (TTC). The regulations for TTC signs can be found in Part 6 of the MUTCD. The general rule of thumb is that 36” x 36” construction signs are used on conventional roads, while 48” x 48” signs must be used on freeways or expressways. There are some exceptions, including the use of 30” x 30” signs, which is why we offer all 3 sizes. Refer to the Temporary Traffic Control Zone Sign and Plaque Sizes chart in the MUTCD for specific guidelines.
  • RETROREFLECTIVITY. First, this does not mean old school reflectivity. Retro, in this case, means to return to the source. So, a retroreflective roadside object will reflect more light from a vehicle’s headlight back toward the vehicle, making the object brighter and more visible. A few years ago, the Federal Highway Administration implemented a new standard for the retroreflectivity of road signs. These standards must be fully adhered to by January 2015. Each of the choices we offer meet or exceed the FHA standards. Our engineer-grade prismatic has an average life span of 7 years and meets ASTM D4956 Type I specifications. Our high-intensity prismatic has an average life span of 10 years, is 3x more reflective and meets ASTM D4956 Type III prismatic specs. Our diamond-grade prismatic is 10x more reflective than engineer grade and exceeds ASTM D4956 Type IX prismatic specs.

You can’t say you weren’t warned if the highway department had proper, clearly marked traffic warning signs in place. However, some warning road signs are confusing, while others may be too dark to be seen at night. We love laughing at pictures of funny and confusing warning traffic signs as much as the next person, but confusion on the road can lead to traffic collisions.


Quick Facts:

  • REGULATIONS. Any traffic warning sign placed along a roadway must adhere to state and federal guidelines. Federal regulations are found in the MUTCD. For example, warning sign placement must be based on an engineering study or on engineering judgment. This is to help prevent the overuse of warning signs which would tend to diminish their effectiveness. Sign size and retroreflectivity (brightness) are also covered in the MUTCD.
  • CLARITY. You may have come across some warning road signs that leave you scratching your head wondering what they mean or why they are there. Some signs will need a supplemental warning plaque hung with an arrow or with wording in order to leave drivers with no doubt about a sign’s meaning. Some signs are necessarily placed hundreds of feet or even a couple miles ahead. In this case it is appropriate to use supplemental warning signs with feet or miles indicated.
  • PERCEPTION-RESPONSE TIME (PRT). This has more to do with sign location on the roadway than sign selection, but the reason certain sizes are required for different scenarios has to do with PRT. Perception-Response Time is the time needed for detection, recognition, decision, and reaction. Basically, the distance the warning sign must be from the road condition is based on how fast most people drive that stretch of road, and the speed to which they must decelerate, thus giving drivers the time needed to see the sign, understand what it says, decide what to do, and then decelerate to the appropriate speed.

These are the convenient informational signs that point you in the direction of a nearby hospital, airport, library, or campground, or guide you along a bike route. Informational signs also include things like parking signs and private property signs. Our informational signs are made of .080 gauge, rustproof aluminum with engineer-grade reflective coating. Most of these signs come in blue or green reflective backgrounds with white reflective graphics and lettering. Avoid frequent replacement of these signs by purchasing Traffic Sign Pro’s high-quality road signs that resist fading in direct sunlight and have an average life span of 7 years.

Did you know that a pedestrian who is hit by a car going 20 mph has an 80-90% chance of survival? However, at just a few miles per hour more, at 25-30 mph, a pedestrian has a 90% chance of fatal injuries. Now you know why school zone speed limits are reduced to 15-20 mph.

You may have noticed over the years that school traffic signs are getting brighter, flashing lights are being added, post reflectors are drawing more attention to school crossing and school zone stop signs, etc. All of these safety precautions appear to be working because there has been a significant decrease in injuries to students walking to and from school.

There are a number of things to take into consideration when choosing the appropriate school road signs for your needs. According to the MUTCD, “the type(s) of school area traffic control devices used, either warning or regulatory, should be related to the volume and speed of vehicular traffic, street width, and the number and age of the students using the crossing.”

The manual also directs that signs such as a school bus stop ahead sign be either illuminated or (here’s a great word) retroreflectorized. This includes the paddles used by crossing guards. All of our signs for school zones are made of sturdy .080 gauge, rustproof aluminum, and meet or exceed state and federal retroreflectivity standards. Both the background and lettering of our signs are reflective and are rated for 7 or 10 years depending on the type of reflectivity used.

Have you ever wondered why a stop road sign is octagon-shaped? It is one of those simple but genius ideas. It lets drivers who can only see the back of the sign know that oncoming traffic has a stop traffic sign, which can only be known because of its distinctive shape.


Quick Facts:

  • Stop signs were changed from yellow to red in 1954 after fade-resistant reflective red coatings became available for use in the manufacturing of signs. This made both the stop light and the aluminum stop sign the same color. It also helped to distinguish the stop sign from yellow warning signs.
  • We know that America leads the world in almost every area imaginable. The same holds true even when it comes to the stop sign. Even in countries where they drive on the left side of the road, they have adopted the red, octagonal stop road sign, right down to the letters STOP.
  • The “American” stop traffic sign was made official in 1968 by the Vienna Convention on Road Signs and Signals affecting most European countries. Many other countries in South America, the Middle East, Asia, Africa—pretty much all over the world—use red on octagon shaped signs to tell drivers to stop, even if they use their own language or the upright palm of a hand.
  • In the US, stop signs are regulated by the Federal Highway Administration which defines the national standards in its Manual on Uniform Traffic Control Devices (MUTCD).

The two most important things to consider when ordering your stop signs are size and retroreflectivity. Table 2B-1 of the 2009 MUTCD will help you determine the size of the stop sign needed. Table 2A-3 of the 2009 MUTCD will help you determine the minimum retroreflectivity levels required. Keep in mind that local regulations may have higher standards and must be consulted.

As the weather warms for the summer months, road construction begins in earnest across the country. From repairing the damage of a harsh winter to expanding roads and building parking lots, summer is the time for all types of road construction. This increased level of activity also means more construction signs and altered street signs are needed to alert drivers of potential hazards and delays.

According to the Advocates for Highway and Auto Safety, motor vehicle crashes are a leading cause of death for Amercians ages 5-34. That’s an alarming statistic, making roadside safety a top priority of all motorists.

Drivers need to know what to expect when they confront a roadway, especially if they’re already familiar with the route and may not realize that something has changed. Alerting drivers of changing speed limits, detours, or traffic signals via an increased presence of street signs helps them maintain vigilance while on the road.

Construction signs, traffic signs, street signs, and parking signs all provide valuable information to drivers. That’s because many drivers rely on their senses to determine what actions to take on the road and which routes are safer to travel. Signs act as instructions to drivers, showing where to go and how to drive appropriately when they get there.

Unmarked roads and construction sites pose a threat to motorists and without traffic signs to guide their driving, they may end up in a situation they’re not expecting to encounter. If a driver knows to expect construction through proper traffic signs, he or she will slow down and keep an eye out for workers; without this forewarning, the driver may put himself and a construction crew in danger.

Drivers may drive too quickly, be unprepared for road conditions, or simply be unaware of a construction crew, all of which pose a threat to all motorists. Even if the driver maintains safe habits, being unprepared for construction and other roadway changes can be a major inconvenience to commuters and others who count on their route being unchanged from day to day. After all, we can all get into the habit of driving the same routes day in an day out.

Depending on the situation, a construction crew may have the need for several types of traffic signs. In addition to obvious construction and detour notices, they may require street signs to label newly-created roadways, new traffic signs for a temporary or new stoplight, or parking signs to outfit a freshly-designed parking lot. Whether the signs are purchased and installed by the property owner, the city government, or construction crew itself, signs are a necessary element to any construction project.
