Access aisles shall be marked with diagonal striping so as to discourage parking in them. A high quality yellow paint recommended by the paint manufacturer for pavement striping shall be used.
Access aisles shall not overlap the vehicular way. Access aisles shall be permitted to be placed on either side of the parking space except for angled parking spaces required by 208.2.4 which shall have access aisles located on the passenger side of the parking spaces (see Figure 502.3 (b).

Accessible parking spaces shall be designated as reserved by providing a permanently mounted R7-8 (U.S. Department of Transportation standard; see Figure 502.6 (a)) sign which contains the international symbol of accessibility. Such signs shall exhibit the dollar amount of the fine as required by the Illinois Vehicle Code [625 ILCS 5/1124 and 301.1] or the higher amount if required by local ordinance (see Figure 502.6 (b)).
