COMS/ACVREP DOMAIN 7 MOBILITY
SKILLS QUESTIONS AND CORRECT
ANSWERS
Basic Trailing Procedure ANSW✅✅Terrain controls the tip of the cane in determining obstacles or
openings
Three-Point Touch ANSW✅✅used to detect objects on side and above level of walking: curb,
hedge, storefronts.
Touch-and-Drag ANSW✅✅Trail a shoreline or remain parallel to drop-off.
Ascending stairs ANSW✅✅Learner approaches riser with 2-point touch; places cane tip on riser,
changes to pencil grasp diagonal cane position & walks up to the cane so that tip is between toes
forward touching riser. To determine where on step learner is, runs vertically held riser to the right
then left with corresponding hand to judge railing so position in center. Check height of riser by
lifting cane tip then the depth by running along to riser of second step. Using vertical grasp between
toes, counts to 3rd step with tip; locks elbow so arm is parallel & cane at midline; leans forward,
proceed to walk up with one foot on each step; cane tip bounces off each step until floats in empty
space. reposition to 2-point touch technique.
Descending Stairs ANSW✅✅Student approaches edge of landing using constant contact or
touch/slide technique; when tip drops off edge, lock it against stair edge with toes resting slightly
over edge. Holds cane vertically & runs it along riser in both hands to determine position on landing.
With cane in pencil grip, raises tip to landing edge to determine height of step; runs along step to
determine depth. Position cane diagonally across body half inch off next step; descend, leaning back
slightly until tip touches landing. 2-point touch walk away
Explain the procedure for using the cane to contact and explore objects and for locating drop-offs
ANSW✅✅Hold cane against object to explore so orientation isn't lost. If there is a change is
surface level; the learner stops and determines characteristics.
What are the components used to analyze intersections? ANSW✅✅1. Identify type of traffic
control,
2. Shape of intersection,
3.Traffic pattern;
, 4. Visit location at different times to determine variability.
What are some common risks when crossing an intersection? ANSW✅✅1. Bicycle traffic,
2.Conflicts with turning vehicles,
3. Drivers running red lights,
4. Undetected/unexpected or don't yield to pedestrians
How can the O&M specialist prepare the learner to make informed decisions? ANSW✅✅Teaching
them effective street-crossing strategies and become reliably skillful;
Discuss risks and possible consequences involved in each situation & how to reduce risks as much as
possible.
Teach alternatives when cost is not acceptable.
Two Way Stop ANSW✅✅At a stop sign on the parallel street; the learner gets into the ready
position and listens for traffic to come to a complete stop.
As a vehicle surges forward & learner determines by listening that it isn't turning, initiate travel using
traffic as a buffer.
If on perpendicular street. learner listens for traffic to complete stop, starts crossing immediately
once determines there is no parallel traffic,
4-Way Stop ANSW✅✅Learner in ready position listens for surge of parallel vehicle after
determining it isn't turning. Then starts crossing while listens to perpendicular vehicle to ensure they
are not moving.
T-shaped intersection with 1-way stop on stem ANSW✅✅Learner listens for perpendicular traffic
and travels with parallel left surge
T-shaped intersection with traffic light controls ANSW✅✅Learner crosses with parallel surge;
determines right turning pause
Simple phase traffic light ANSW✅✅Learner detects parallel surge and travels with it as a buffer.
Complex phase traffic light with left turn arrows ANSW✅✅Learner travels with near parallel
surge, detecting turning vehicles.
