Safe Driving
• Complicated set of visual motor actions based on complex input and requiring precise action
• Impairment in any one area can dramatically impact safe driving
• Compensation methods may or may not be sufficient
• Many states require re-test after a change in physical status; driver’s license lists qualification for driving (adaptive equipment)
• Most (all?) insurance companies require notification with change in physical status
Safe, Independent Driving is Comprised of:
• Getting in/out of the vehicle• Driving to various locations• Maintaining the vehicle in good
working condition
Adaptive equipment
is available for all of these aspects of driving
The first big decision….
This decision is usually based on whether (s)he can transfer into the driver’s seat
and stow his/her wheelchair
Will the person use a van or a car?
Driving while seated in driver’s seat
• Usually car; can be truck, van, etc.
• Transfer to driver’s seat• Stowing wheelchair (or other
device)– manually– electrical hoist
Lifting the wheelchairinto the vehicle
Car Topper- can be set-up to use while seated in seat
Trunk rack: attaches to tow bar; requires
person to walk around car to seat
Driving while seatedin a wheelchair
• Usually van• Lift v. ramp
– lift/lower
• Opening/closing door• *Head height• Restraint system/Seat
belt• Head rest
Full Size Van With Raised RoofAnd Windshield
Lowered floor is also often necessary
Van Entry
Swing arm lift
Full-size van: side lift
Mini-van: rear entry ramp
Mini Van- these have lowered floor and ability to “kneel”
Lift
Ramp
Full Size Van- side lift
Switch options:
•Driver control
•Pendant
•Magnetic switch in light box
raising/lowering and
opening/closing independently
Restraint systems
Two restraints are needed:• One to hold the wheelchair to
the vehicle– Lock-down– Tie-down
• One to hold the person
Restraint Systems
Tie down system requires
assistance
Lock down system may be done independently
The next big decision…
What type(s) of adaptive equipment will be necessary for the person to be safe and drive easily?
Driving Adaptations to Compensate for Motor
Impairments
• Acceleration- gas pedal
• Braking- brake• Steering- steering
wheel• Other radio
A/C windows
horn
mirrors
window washer
Driving Adaptations For Acceleration• Left foot
accelerator• Hand control
– push/pull control– push down/forward
control
• Joystick control (Digidrive)
• Low effortLeft foot accelerator
Driving Adaptations For Braking
• Hand Control– push/pull control– push down/forward control
• Joystick control (digidrive)• Low effort
Acceleration and Braking
Electronic gas and braking system
Push down/forward system:
Blue- brake
Pink- acceleration
Joystick- Digidrive
Driving Adaptations For Steering
• Low- or Zero Effort• Joystick• Steering handle
– Spinner Knob– Tri-pin (quad holder)
• Steering wheel size• Steering wheel position
– horizontal– closer to driver
Driving Adaptations(steering) cont.
Small steering wheel with cuff
Joystick- Digidrive
Spinner knob
Other Stuff• Adjusting
Mirrors• Horn• Heat and A/C• Turn Signals• Radio• other?
Power Headrest System
Headrest with switches
imbedded
Custom Adaptations
Extender for turn signal
Foot block to prevent left foot from interfering
Maintenance and Upkeep
• Getting gasoline- most states require stations to provide service at self-service cost to people who need
• Regular Maintenance• Road side repairs– not just for
the vehicle, but also for the lift equipment and other adaptive driving equipment
Driver evaluation
• Visual acuity• Visual fields• Reaction time• Motor abilities• Cognition
– Reading– Problem solving– Planning– Safety judgment
Driver Simulator- used most often for evaluation and screening
May also be used for driver training
• Standards– RESNA/ANSI standards for restraints– Crash testing

Time to change focus to
Augmentative Communication
American Speech-Language-Hearing Association (ASHA)
• ASHA is the professional, scientific, and credentialing association for more than 123,000 members and affiliates who are speech-language pathologists, audiologists, and speech, language, and hearing scientists in the United States and internationally.
Augmentative and Alternative Communication (AAC)
• Augmentative and alternative communication (AAC) refers to ways (other than speech) that are used to send a message from one person to another. We all use augmentative communication techniques, such as facial expressions, gestures, and writing, as part of our daily lives. In difficult listening situations (noisy rooms, for example), we tend to augment our words with even more gestures and exaggerated facial expressions. (ASHA)
• Augmentative communication users don’t stop using speech
Picture Cards
Picture Exchange Communication System (PECS)
• PECS is an alternative communication system that uses picture symbols. It is taught in six phases starting with a simple exchange of a picture symbol for a desired item. Individuals learn use picture symbols to construct complete sentences, initiate communication, and answer direct questions.
• Used frequently with children with autism
