What should you anticipate at the bridge ahead?
Correct answer: A bridge with a narrower roadway
NARROW BRIDGE warns about the roadway width at the bridge. It is different from a drawbridge or clearance warning.

Correct answer: A raised irregularity in the road
A bump is a raised surface irregularity. Compare it with DIP, which identifies a depression.
Source: FHWA MUTCD 2009 Figure 2C-6 — W8-1 Bump ↗
How does the road surface change here?
Correct answer: A depression in the road surface
DIP warns of a low depression in the roadway rather than a raised bump or a change in lane count.

What change in road surfacing should you expect?
Correct answer: A transition away from a paved surface
The message concerns the road surface. Do not confuse the end of pavement with a DEAD END warning.

Which part of the roadway may not support your vehicle normally?
Correct answer: The shoulder beside the travel lane
The warning applies to the shoulder surface beside the traveled roadway. It is not an invitation to use that area as an extra lane.

What difference between neighboring lane surfaces should you expect?
Correct answer: Adjacent lane surfaces at different levels
The warning refers to a difference in lane-surface elevation, not a difference in speed limits or who may use each lane.
Source: FHWA MUTCD 2009 Figure 2C-6 — W8-11 Uneven lanes ↗
What does this sign mean?
Correct answer: The road has no centerline marking
An absent centerline is the condition being warned about. It does not establish one-way operation or unrestricted passing permission.

What should you be alert for at the edge of the pavement?
Correct answer: A lower shoulder next to the pavement edge
The symbol and plaque warn of an elevation drop at the shoulder, rather than a required lane maneuver.

Which assumption should you avoid after seeing this sign?
Correct answer: That the old lane arrangement still applies
The warning alerts familiar drivers as well as new visitors to a changed arrangement ahead. Pay attention to current signs and markings instead of relying on memory.

What lane change should you anticipate ahead?
Correct answer: One lane ends instead of continuing separately
The taper shows a lane ending. On the added-lane symbol, the incoming path continues as a separate lane alongside the through lane.
Source: FHWA MUTCD 2009 Figure 2C-8 — W4-2 Lane ends ↗
How will traffic from the joining road enter?
Correct answer: Entering traffic has an added lane
The separate continuing paths distinguish an added lane from the merging-traffic warning, where the incoming path joins the through path.
