What the test wants you to know
The mistake people make
If you do have to leave the roadway in an emergency after seeing this sign, ease off the pavement gradually rather than jerking the wheel, because a soft shoulder can grab a tire and pull the vehicle further off course than a firm one would. It shows up most often right after fresh paving or resurfacing work, before the shoulder has been compacted.
The sign people confuse it with
Soft Shoulder gets mixed up with Pavement Ends more than any other pairing in this category. Put them side by side and the difference is obvious, which is exactly why it is worth doing once rather than meeting them cold in the exam.
Soft Shoulder
