Standard Highway Signs and Markings (SHSM) BookDesign Details, Interpretations These signs may also be used at intermediate points along the ramp, especially if the ramp curvature changes and the subsequent curves on the ramp have a different advisory speed than the initial ramp curve. In Maine, the passing lanes are a jog over, so you can just stay in the center passing lane if youre half asleep. Entering and exiting a major roadway | Alberta.ca 01 A ONE LANE BRIDGE (W5-3) sign (see Figure 2C-5) should be used on two-way roadways in advance of any bridge or culvert: Guidance: Your driving licence has been suspended. You need to properly judge the time, speed, and space before your vehicle maneuvers into the other lane of traffic. If the curve has a change in horizontal alignment of 135 degrees or more, the Hairpin Curve (W1-11) sign may be used instead of a Curve or Turn sign. The advisory speed displayed on the combination Horizontal Alignment/Advisory Speed sign should be based on the advisory speed for the horizontal curve using recommended engineering practices (see, The Turn (W1-1) sign or the Curve (W1-2) sign may be combined with the Cross Road (W2-1) sign or the Side Road (W2-2 or W2-3) sign to create a combination Horizontal Alignment/Intersection (W1-10 series) sign (see, Elements of the combination Horizontal Alignment/Intersection sign related to horizontal alignment should comply with the provisions of, The use of the combination Horizontal Alignment/Intersection sign shall be in accordance with the appropriate Turn or Curve sign information shown in, A One-Direction Large Arrow (W1-6) sign (see, A One-Direction Large Arrow (W1-6) sign may be used to supplement a Turn or Reverse Turn sign (see. Standard: The truck tips in the opposite direction. The effectiveness of the placement of warning signs should be periodically evaluated under both day and night conditions. THE RULES (not laws, just common-sense ones, really) Where two lanes merge into one, the vehicle in front has the right of way.

In situations where there is a need to warn drivers to watch for other slower forms of transportation traveling along the highway, such as bicycles, golf carts, horse-drawn vehicles, or farm machinery, a SHARE THE ROAD (W16-1P) plaque (see, A W16-1P plaque shall not be used alone.

The One-Direction Large Arrow sign directing traffic to the right shall not be used in the central island of a roundabout. 03 Permanent obstructions causing the limited visibility might include roadway alignment or structures. The combined Bicycle/Pedestrian (W11-15) sign may be used where both bicyclists and pedestrians might be crossing the roadway, such as at an intersection with a shared-use path. 01 Vehicular Traffic Warning (W8-6, W11-1, W11-5, W11-5a, W11-8, W11-10, W11-11, W11-12P, W11-14, W11-15, and W11-15a) signs (see Figure 2C-10) may be used to alert road users to locations where unexpected entries into the roadway by trucks, bicyclists, farm vehicles, emergency vehicles, golf carts, horse-drawn vehicles, or other vehicles might occur. The merging traffic sign will typically indicate which lane should be merging into the other. An advance sign tells drivers they will soon have a chance to pass. 04 Type 3 object markers with stripes that begin at the upper right side and slope downward to the lower left side are designated as right object markers (OM3-R).

Among the established engineering practices that are appropriate for the determination of the recommended advisory speed for a horizontal curve are the following: The 16, 14, and 12 degrees of ball-bank criteria are comparable to the current AASHTO horizontal curve design guidance. Obstructions not actually within the roadway are sometimes so close to the edge of the road that they need a marker. 03 If used, the combination Horizontal Alignment/Advisory Speed sign shall not be used alone and shall not be used as a substitute for a Horizontal Alignment warning sign and Advisory Speed plaque at the advance warning location.
