Navigating the roads of the United States can be a daunting task, especially if you don't have a map or GPS device. However, understanding how to identify navigational traffic signs and mile markers can help you match your directions to your actual location. American highways are dotted with millions of traffic signs, most of which are for navigational purposes. Let's take a look at some of the common types of traffic signs and how they can help you find your way.
Mile Markers- Mile markers are small green rectangular signs with white numbers that appear on major highways and interstates.
They inform drivers of the numerical distance at which they are on the road. Mile markers are especially useful for determining your precise location on desolate stretches of road. For example, if you pay attention to the mileage marks, you can inform a tow truck driver that you are paralyzed on the 58th mile of a particular road.
Traffic Signs- Traffic signs, which are sometimes lost or stolen, are long rectangular signs that are placed on the top of tables eight to ten feet at the end of the streets. These signs inform drivers of road names.
Certain types of roads have shields with particular shapes. State highways always appear as white shields outlined in black with the corresponding road number in black in the center of the shield. Interstate highways also appear in the shape of a shield, but are outlined in blue with red and the corresponding interstate number appears in the center in white.
Destination Signs- Large green signs in the form of billboards appear along major highways and interstates. They list the next destinations and the distance to each one.
These signals are useful for calculating refueling stops, rest stops and for matching your location with the map or GPS directions.
School Crossing Signs- When you see school crossing signs, be sure to slow down immediately. If you're in a hurry, it might be best to choose a different route first thing in the morning or in the middle of the afternoon to avoid delays.
Construction Signs- These signs indicate the areas where road works are being carried out. These signs have black markings, which sometimes indicate the presence of a flag-bearer, a double thin area, or rough surfaces. These orange construction signs can also affect your route because they can indicate detours. By familiarizing yourself with these common types of traffic signs and mile markers, you can be sure that your driver is familiar with the route you need to take.
