Signs, Signals & Road Marks Chp. 5
Yield Sign
A 3-sided red YIELD sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed. Yield means to give the right-of-way to traffic on the road you are entering or crossing
Yellow Lines
A broken (dashed) yellow centerline on the left side of a travel lane indicates passing is allowed in that direction. A solid yellow centerline on the left side of a travel lane indicates passing is prohibited in that direction Along a one-way ramp, one-way street, or a one-way roadway that is one half of a divided highway, YELLOW edgelines mark the left edge of pavement or the boundary between a travel lane and an adjacent left shoulder. DOUBLE BROKEN (dashed) YELLOW line means A lane that is operated in different directions at different times of the day, such as a reversible lane system; shared use
Stop Sign
An 8-sided red STOP sign indicates that you must make a full "STOP" whenever you see this sign. Stop at the white limit line (a wide white line painted on the street) or before entering the crosswalk. If a limit line or crosswalk is not painted on the street, stop before entering the intersection. Check traffic in all directions before proceeding.
Curb Color Meaning
Curb colors are used to indicate parking restrictions. A RED curb indicates that ALL parking, stopping, or standing (see our SIGNS page for definitions) is prohibited. The sole exception is for transit buses, which may stop ONLY at a signed BUS STOP. A BLUE curb indicates that UNLIMITED parking is permitted, providing the vehicle has either a HANDICAPPED placard hanging from the rear view mirror, or a HANDICAPPED license plate. A YELLOW curb is used to indicate parking, stopping, or standing is permitted, for delivery or drop-off, usually for commercial purposes. A GREEN curb indicates that parking is permitted, but only for a period of time. The permissive times are either placed on an adjacent sign, or painted directly onto the curb itself. A WHITE curb is similar to the YELLOW curb, but is a general purpose curb, for dropping off passengers, mail, etc. As a general rule, the driver must remain in the vehicle. If a curb is unpainted, then parking is permitted, with no restrictions, unless a sign is used to indicate otherwise.
Double solid Lines
Do not cross
Business Loop Signs
If an Interstate splits off and enters a city business center directly, or goes immediately around it, a special marker called a BUSINESS LOOP or SPUR is used
White Lines - Longitudinal
Indicate lanes edges. A dashed white line marks a lane that can be crossed over, while a solid white line indicates a line where crossing over is either discouraged or prohibited.
When the safe, navigable speed is LESS than 35 mph, a curvature in the road is called a if GREATER than 35 mph, it is called a
TURN CURVE
The Interstate System
The Interstate Numbering System consists of even and odd numbers. EVEN numbered routes run in an east-to-west direction, while ODD numbered routes run south-to-north. In addition, the EVEN numbers get bigger as you move further NORTH, and the ODD numbers get bigger as you move EAST. The standard Interstate routes will always have one or two digits (I-5 or I-70), and will appear on a blue-and-red shield. Then there are SPURS and LOOPS. These signs have 3 digits (I-495). As a GENERAL rule, if the first digit is EVEN, the route is an Interstate Loop, which means it goes (usually) around a city or urban area and then reconnects to the Interstate again, with an Interstate at both ends. If the first number is ODD, then the SPUR route LEAVES an Interstate, and connects with a major highway, or,simply ends (for example, at another street).
Transverse - Crosswalks
The traditional two white lines (yellow in a school zone) is the most common style. When a higher degree of visibility is required, diagonal or perpendicular lines may be used.
White Lines - Transverse
White transverse lanes lines (perpendicular to traffic flow) are used to indicate stopping, yielding, and cautionary areas, where traffic is controlled for one reason or another.
yellow and black circular sign
indicates that you are approaching a railroad crossing
Grade
the amount of rise or fall per 100 feet of roadway. A 7% grade means that the roadway hill goes downward 7 feet for every 100 feet forward (or vice-versa for uphill).
