You approach a NARROW BRIDGE AHEAD warning sign and an oncoming driver has a wide vehicle taking up part of your lane. What does the manual tell you to do?
-
A.
Sound your horn and continue at speed
-
B.
Wait until they clear the area Correct
-
C.
Move onto the shoulder to give room
-
D.
Accelerate to clear the bridge quickly
The answer is "Wait until they clear the area"
The manual says to wait until the oncoming wide vehicle clears the area. It warns that there generally is no shoulder on a narrow bridge, so drifting right is not an option. Answer C rests on the assumption that every span has a paved shoulder available for emergency use.
The traps in the wrong answers
A. Sound your horn and continue at speed
The manual gives no horn instruction here; it says to slow and yield space instead. This answer falls back on a horn-warning reflex when the rule is simply to hold back and wait.
C. Move onto the shoulder to give room
The manual notes there generally is no shoulder on a narrow bridge, so moving over is not an option. This answer assumes every span has a paved shoulder available for emergency use.
D. Accelerate to clear the bridge quickly
The manual says to slow down for a narrow bridge or underpass, not to speed through it. This answer reasons that going faster clears the pinch point sooner, opposite of the manual's slow-down cue.
