Regulatory Signs :

Regulatory Signs Tell you what you can and cannot do at certain times and places. Direct traffic to stop, yield or go in a particular direction. Obey whenever you see them. They are just as enforceable on private property as on public roadway.

Regulatory Signs :

Regulatory Signs Stop signs are the only octagonal sign on the road Do Not Enter signs prohibit you from turning onto one way roads One Way signs tell the driver that they have only one legal way to turn. When you see a No U Turn sign, you are prohibited from making U turns in that area.

Warning Signs :

Warning Signs Alert you to hazards or possible hazards ahead Most are diamond shaped with a yellow background and black writing

Warning Signs :

Warning Signs This sign warns drivers of an approaching stop light This sign alerts drivers that they are in an area where bicyclists should be expected This sign warns people of an upcoming lane merging

Guide Signs :

Guide Signs Tell you where you are, where you are going, and how to get there.

Recreational Signs :

Recreational Signs Always in the shape of a rectangle or trapezoid Tell you about nearby places of cultural interest and public recreation such as historical sites, museums, and national parks

International Signs :

International Signs Use symbols instead of words because they are designed to be understood without knowing a particular language.

Traffic Signals :

Traffic Signals Often found in intersections where traffic is heavy or there is a high level of risk that different roadway users will cross paths.

Traffic Signals :

Traffic Signals A red light signals that the drive come to a complete stop. A flashing red light works just like a stop sign. A yellow light warns the driver to slow down. If you see a flashing yellow light, slow down, give up the right-of-way, and proceed with caution. A green light means to proceed if safe.

Traffic Signals :

Traffic Signals A red arrow signifies that you cannot go in the direction indicated until the light changes to green. At a yellow arrow, come to a complete stop if you can do so safely. At a green arrow, proceed in the direction indicated if it is safe to do so.

Slide 19:

On-ramp meters usually have red and green lights (some also have yellow) and allow one or more vehicles in each on-ramp lane to proceed at intervals On-ramp meters usually operate only have peak traffic hours, otherwise they are turned off to allow cars direct freeway entry when traffic is light. ON-RAMP METERS

Slide 20:

Warning signals can be found at schools, construction zones, near fire stations and hospitals. These signals usually flash yellow, but in some cases, they may turn to a steady yellow followed by a steady red when pedestrians or emergency vehicles are passing. Some roadways have permanently flashing yellow lights to warn drivers of an approaching curve or exit, dangerous intersection, dividing freeway, or any other place requiring vehicles to slow down. WARNING SIGNALS

Slide 21:

Many highways have special electronic signs that provide up-to-date information about lane and exit closings, delays, collisions, weather problems, carpooling, and other important items that affect driving conditions. These signs are usually posted in areas with a lot of traffic or where bad weather is common. Variable Message Signs can be set up by construction or maintenance crews to help direct traffic or warn drivers of problems on the roadway ahead. Variable Message Signs

Slide 22:

Pedestrian Signals are designed for intersections with heavy pedestrian (walker) traffic. Most are placed just below traffic signals. Pedestrians are allowed to cross when they face a green or white “walk” signal or the symbol of a person walking. When they face a flashing orange or red “don’t walk” signal or the symbol of a raised hand, they must wait at the curb if they have not yet started to cross the street, or they should clear the intersection if they are still in it. PEDESTRIAN SIGNALS

Slide 23:

Sometimes signal lights malfunction or traffic becomes so heavy at an intersection that police or traffic control officers are called in to direct traffic. Holding the hand up, palm facing outward, is the signal to stop. Waving one arm forward is the signal to proceed Hand signals always take priority over signs and traffic signals.

ROADWAY MARKINGS, LANES, AND PAINTED CURBS

Slide 25:

Broken or dotted white lines separate traffic moving in the same direction and may be crossed when changing lanes or merging. Solid white lines are used to separate driving lanes from the shoulder of the road or a bicycle lane and to mark fixed obstacles such as bridge supports on one-way roads. Solid lines should never be crossed in order to pass. Special white lines indicate the “neutral area” between freeway lanes and on-ramps and off-ramps. WHITE TRAFFIC LINES

Slide 26:

Yellow lines separate traffic going in opposite directions on a two-way road. They may be solid or broken or a combination of solid and broken yellow lines. They may also be single or double lines. If two-way traffic is separated by a divider, the left side of the roadway is marked with a single yellow line. Solid yellow lines also mark obstacles in the center of a two-way road. To avoid driving the wrong way against oncoming traffic, stay to the right of the yellow line(s). You can move to the left only under certain circumstances. YELLOW TRAFFIC LINES

Slide 27:

The pattern of solid and dashed yellow lines used on a roadway indicates whether passing is permitted. No passing is allowed if there are two solid yellow lines. If a solid and a broken yellow line appear together, passing is allowed if there are no oncoming cars and you are next to the broken line; passing is not allowed if you are next to the solid line. If there is only one broken yellow line and no oncoming cars, passing is allowed.

Slide 28:

Special roadway markings are used to separate lanes reserved for certain actions or vehicles from the normal lanes of traffic. Turn lanes are often added near intersections to separate left- or right-turning traffic from through traffic at an intersection. White arrows, often accompanied by the word “only”, indicate that you must stay within a designated lane while turning onto the cross street. Some turn lanes have multiple arrows, allowing you to turn left or right or go straight. Special Lanes

Slide 29:

A center turn lane between two opposing directions of traffic – also called a “two-way left-turn lane” – is designed for left turns only from either direction. This line is marked by parallel solid and broken yellow lines, sometimes accompanied by white arrows painted on the pavement that point left and right. Vehicles moving in either direction can use these lanes to make left turns into another road or driveway.

Slide 30:

Commuter lanes are an efficient way to minimize urban traffic during rush-hour periods. Commuter lanes are separated by broken double-yellow lines. You can cross these lines only if the overhead signal above the lane you wish to enter has a green X or is a sign permit you to do so. When you encounter commuter lanes, remember that traffic will be traveling in lanes otherwise used by opposing traffic, so be sure to stay cautiously aware of other drivers.

Slide 31:

Carpool lanes are special lanes designed for buses, motorcycles, and vehicles carrying a minimum of two or sometimes three persons. Carpool lanes have distinctive roadway markings – usually a diamond symbol and words such as “carpool only” – and posted signs. Be careful not to stray into a carpool lane if you are not eligible to drive in one, and never cross solid white or yellow lines to enter or leave a carpool lane.

Slide 32:

In urban areas where there is a lot of congestion and bus traffic, buses may have their own lanes. This type of lane, which often has “bus only” roadway markings and/or signs, is usually the farthest lane. You cannot enter a bus lane unless you are making a right turn. Many roadways have a special lane for bicycles, which is on the far-right side of a two-way roadway. These bicycle lanes are separated from the traffic lanes by a solid white line, which changed into a broken line near intersections. Vehicles are permitted to enter the bicycle lane on a two-way roadway only where the line is broken to make a right turn. Bicycle lanes sometimes have a bicycle symbol and/or the words “bike lane” painted on the roadway inside the lane .

Slide 33:

A limit line is either a wide white or yellow stop line at an intersection or the nearer of two crosswalk lines. Crosswalk markings are often connected with diagonal lines, or the crosswalk itself may appear as a series of painted bars or raised markers on the road. Sometimes words such as “stop” or “X walk” are also painted on the pavement. When you are required to come to a stop at an intersection, your vehicle must come to a full stop behind the limit line. LIMIT LINES

Slide 34:

Curbs and parking stops are painted to regulate parking. If a curb is painted any color, it means that there are special parking rules. Yellow – designates a loading zone. Red – designates areas in which you cannot stop, park, load, or stand. Bright White – designates areas that permit stopping for brief periods only when picking up or dropping off people or mail. Green – designates a time-limited parking zone. Blue – designates a parking zone for people with disabilities . PAINTED CURBS

Slide 35:

Some roads are equipped with raised buttons or square-shaped reflectors to help drivers stay within lanes. Botts ’ dots are placed on or between dividing lines. They may also be used on the edge of roadways. Rumble strips are grooved or raised sections of the roadway commonly found before dangerous intersections and toll areas and alongside individual lanes or shoulders of highways and freeways. Speed bumps are raised slabs of pavement usually found in parking lots, residential neighborhoods, large condominium or apartment complexes, and even on some narrow winding streets with poor visibility.
