route.

Two parking

502.3.1 Width.

Access aisles serving car and van parking

spaces

shall be 60 inches (1525 mm)

wide minimum.

502.3.2 Length.

Advisory 502.3 Access Aisle.

Accessible routes must connect parking spaces to

accessible entrances.

In parking facilities where the accessible route must cross vehicular

traffic lanes, marked crossings enhance pedestrian safety, particularly for people using

wheelchairs and other mobility aids.

Where possible, it is preferable that the accessible

route not pass behind parked vehicles.

Advisory 502.3.3 Marking.

The method and color of marking are not specified by these

requirements but may be addressed by State or local laws or regulations.

Because these

requirements permit the van access aisle to be as wide as a parking space, it is important

that the aisle be clearly marked.
