A

The center line markings on undivided two-way roadways with four or more lanes for moving motor vehicle traffic always available shall be the two-direction no-passing zone markings consisting of a solid double yellow line as shown in Figure 3B-2.

17
Q

When are centerlines required?

A

Center line markings shall be placed on all paved urban arterials and collectors that have a traveled way of 20 feet or more in width and an ADT of 6,000 vehicles per day or greater. Center line markings shall also be placed on all paved two-way streets or highways that have three or more lanes for moving motor vehicle traffic.

18
Q

Where can the “Minimum Passing Sight Distances for No-Passing Zone Markings” be found?

A

MUCTD Chapter 3 - Table 3B-1

19
Q

What is the passing sight distance for a vertical curve?

A

MUTCD chapter 3- Figure 3B-4
The passing sight distance on a vertical curve is the distance at which an object 3.5 feet above the pavement surface can be seen from a point 3.5 feet above the pavement (see Figure 3B-4).

20
Q

What is the passing sight distance for a horizontal curve?

A

MUTCD chapter 3- Figure 3B-4
The passing sight distance on a horizontal curve is the distance measured along the center line (or right-hand lane line of a three-lane roadway) between two points 3.5 feet above the pavement on a line tangent to the embankment or other obstruction that cuts off the view on the inside of the curve (see Figure 3B-4).

21
Q

What color pavement markings delineate the separation of traffic lanes in the same direction?

A

When used, lane line pavement markings delineating the separation of traffic lanes that have the same direction of travel shall be white.

22
Q

What are characteristics for lane-reduction transition markings?

A

MUTCD Chapter 3 - Figure 3B-14
1. Lane-reduction arrows are optional for speeds of less than 45 mph
2. See Section 3F.04 for delineator spacing
3. L = WS for speeds of 45 mph or greater and L = WS^2/60 for speeds of less than 45 mph, where:
L = Length of taper in feet
S = Posted, 85th-percentile, or statutory speed in mph
W = Offset in feet
4. d = Advance warning distance (see Section 2C.05)

23
Q

What are recommended yield line layouts

A

MUTCD Chapter 3 - Figure 3B-16
Yield lines are white triangular lines separated from each other by 3-12”. The height of the triangle is 1.5 times the base.

24
Q

What are the International Symbol of Accessibility Parking Space Marking dimensions?

A

MUTCD Chapter 3 - Figure 3B-22
