Walk as much as possible. Walking helps to keep you fit and healthy and can usually get you anywhere you want to go.
Take the bus. Get a current route map and schedule, and you will probably find that your local bus system can deliver you to all the places you regularly frequent.
Take the train or subway. Many major cities have subway or other rapid transit rail systems, and these can be a great way to get around. Most stations are also equipped for handicapped riders.
Rideshare or carpool. Even if you aren't driving, you can still contribute gas or coffee money to a carpool and let the others drive.
Arrange local transportation with a service that provides rides for people with physical disabilities if you are mobility impaired. Many of these services will pick you up and drop you off at your own home as long as you call in advance to arrange it.
Ask friends or family to include you in errands and grocery shopping trips whenever possible; many people will probably be glad to help out.
Hire a student with a good road safety record to drive you around or run errands for you once or twice a week. Contact the student employment center at your local college or university for information.
