These blue signs tell you about services or facilities along the highway. These signs may indicate gas, food, and lodging are available at the next exit, a rest area is ahead, an electric vehicle charging station is available or a facility or parking area is accessible to a person with a disability. They can also indicate the road to a hospital.

State legislatures establish maximum speed limits according to road class (e.g., Interstate highways) and geographic area (e.g., rural vs. urban areas). These are the factors taken into consideration while determining the speed limit for a road -

This sign means you must come to a complete stop. Yield to other vehicles and stop and stay stopped for pedestrians crossing in marked or unmarked crosswalks. When it is safe, you may enter the intersection.

This sign warns you not to enter a road or freeway. You will see this sign if you are going the wrong way. Study For Your Tests

Traffic signals control the right of way and provide for a smooth, orderly flow of traffic. If a signal appears dark, such as during a power failure, you should stop as if there are stop signs in all directions. When a traffic signal is out of order and flashes yellow or red, you must obey that signal.

Signs often use symbols or pictures rather than words. Each type of sign has a special color and shape to help you easily recognize the sign at a glance.

Speed limitsign meaning

A TRAFFIC LAWS PHOTO ENFORCED sign may be installed at a jurisdictional boundary to advise road users that some of the traffic regulations within that jurisdiction are being enforced by photographic equipment.

Setting speed limits “for roads open to public travel” in the United States has always been the responsibility of state and local governments. Various engineering and traffic studies are conducted for a long time to set speed limits.

Advises the safe speed for freeway ramps and curves. This sign may be used with other signs. Signs may be electronic and may change based on current conditions.

Minimum Speed Limit Signs help maintain safety by keeping all traffic moving at the same pace. It can become dangerous if there is a difference in the speeds of vehicles moving on the same road. The more significant the difference in speeds, the higher the chances are for damage.

65 was the speed limit allowed by Congress in 1987 for selected rural freeways before the National Speed Limit was lifted in 1995.

You must obey all official signs, signals, and markings unless you see a police officer or road worker redirecting traffic.

Traffic signs that prohibit certain actions or movements are red in color and increase safety by controlling the flow of traffic through intersections.

A green signal means all movements—straight ahead, left or right turns—are permitted, unless prohibited by a sign. Left turns must first yield to pedestrians and oncoming traffic. Right turns must first yield to pedestrians.

A steady red arrow means stop and remain stopped until the signal changes, except for allowed turns on red. The same turns allowed for a steady red signal are allowed for a red arrow.

According to the Table of “Sizes of regulatory signs” included in MUTCD Chapter 2B, the minimum size required for a Speed Limit Sign must be 18” X 24”. This sized sign is visible from a distance of 240 feet. On conventional single lane roads, the MUTCD Speed Limit Signs should at least be 24” x 30” (visible from a distance of 300 feet), while on multi-lane roads, it should be 30” x 36”. On expressways, the size should be 36” x 48”, whereas, on freeways, the Speed Limit Signs must be 48” x 60”. All these sizes are width x height.

The Manual on Uniform Traffic Control Devices (MUTCD) requires all speed limits to be in 5 MPH increments. Although there is no confirmed reason behind this decision, it could be because, for a long time in the U.S., most speedometers had index marks only on 5 MPH increments.

A PHOTO ENFORCED word message sign may be mounted below a regulatory sign to advise road users that the regulation (like speed limit) is being enforced by photographic equipment.

Speed limit

Every state has a basic speed statute that requires drivers to operate their vehicles at a speed that is reasonable and prudent for conditions. This basic rule is contained in the Uniform Vehicle Code (UVC) of that state. Maximum posted speed limits are usually set at a higher value for rural roads as compared to urban roads.

Be alert for people crossing your path. These signs may include a flashing yellow beacon that indicates a pedestrian is crossing, has recently crossed or is about to cross.

This also applies to vehicles that can’t maintain highway speeds like bicycles, go-karts, farm equipment, heavy equipment haulers, and anything else that can’t maintain speeds like other vehicles. Law enforcers can ticket those that “impede the flow of traffic”

A flashing yellow arrow means that you may make the movement indicated by the arrow, but first you must yield to pedestrians and oncoming traffic. Oncoming traffic has a steady green signal.

Also, 25, 55, and 65 have always been important numbers in the American speed limit history. These values were very popular and would have been considered as important factors for speed limits in multiples of 5 because:

Warning signs are yellow and alert you to known possible hazards or a change in road conditions ahead. As a driver, you are ultimately responsible for recognizing and reacting correctly to changing conditions, signed or not. Not all warning signs are shown here.

A steady yellow arrow warns you that the signal is about to turn red. Stop before entering the intersection, or if you cannot stop safely, drive carefully through it.

However, the government does not decide speed limits for “roads within private gated properties, except for gated toll roads, where access is restricted at all times, parking areas, driving aisles within parking areas and private grade crossings.”

Regulatory signs are rectangular with black words or symbols on a white background and tell you what to do. They are posted at or near where the requirement applies. Not all regulatory signs are shown here.

For private roads like indoor parking lots and driveways, however, you can also use a 12” x 18” Speed Limit Sign which is visible from a distance of 180 feet.

The FINES HIGHER Sign is used to warn road users when increased fines are imposed for violating traffic rules like exceeding the speed limit within designated roadway segments. Fines Higher Signs must be posted where some kind of construction or maintenance work is going on or where the roadway, shoulder, or other conditions, including the presence of a school, require a speed reduction or extra caution. FINES HIGHER plaque shall be mounted below a regulatory or warning sign in a temporary traffic control zone, a school zone, or other applicable designated zone.

You are allowed to make the following turns on red after coming to a complete stop unless a sign or police officer states otherwise:

The lane is reserved for vehicles carrying at least two or more persons as noted on the sign. A white diamond may be painted on the lane.

Safety corridors are designated stretches of highway with more fatal and serious injury collisions than the statewide average. Turn on your lights for safety. Signs identifying safety corridors may include diamond shaped flags.

The signs below prohibit certain actions. When you see a sign with a red circle and a slash mark, it means do not make the turn shown.

This sign may appear below a stop sign. Traffic turning right may turn without stopping. Other traffic must stop and yield right of way.
