What does the TRUCK ESCAPE RAMP sign mean?

MUTCD Section 2C.15 says truck escape (or runaway truck) ramp signs should be placed about 1 mile and ½ mile before the grade and the ramp, with an extra sign at the gore where the ramp leaves the road. A RUNAWAY VEHICLES ONLY sign should be installed near the ramp entrance to discourage other road users from entering, and No Parking signs should be placed there too.
