Illinois General Assembly - Illinois Compiled Statutes

Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

(625 ILCS 5/12-805) (from Ch. 95 1/2, par. 12-805)

Sec. 12-805.

Special lighting equipment.

Each school bus purchased as a new vehicle after December 31, 1975
shall be equipped with an 8-lamp flashing signal system. Until December
31, 1978, all other school buses shall be equipped with either a 4-lamp
or an 8-lamp flashing signal system.  After December 31, 1978, all school
buses shall be equipped with an 8-lamp flashing signal system.

A 4-lamp flashing signal system shall have 2 alternately flashing red
lamps mounted as high and as widely spaced laterally on the same level
as practicable at the front of the school bus and 2 such lamps mounted
in the same manner at the rear.

An 8-lamp flashing signal system shall have, in addition to a 4-lamp
system, 4 alternately flashing amber lamps. Each amber lamp shall be
mounted next to a red lamp and at the same level but closer to the
centerline of the school bus.

Each signal lamp shall be a sealed beam at least 5 1/2 inches in
diameter and shall have sufficient intensity to be visible at 500 feet
in normal sunlight. Both the 4-lamp and 8-lamp system shall be actuated
only by means of a manual switch. There shall be a device for indicating
to the driver that the system is operating properly or is inoperative.

A school bus may also be equipped with alternately flashing head
lamps,
which may be operated in conjunction with the 8-lamp flashing signal
system.
