Operator and base
Who runs CHART
Maryland Department of Transportation State Highway Administration administers or operates this public motorist-assistance program. The service works through mobile patrol vehicles and traffic-management dispatch rather than as a repair shop that motorists visit.
The official program material reviewed for this page does not publish a public walk-in patrol base. Use the request or dispatch method above rather than traveling to an agency office for roadside help.
