(A) Care­less Dri­ving.  It shall be unlaw­ful to oper­ate a vehi­cle in the Coun­ty in a care­less man­ner so as to inter­fere with the safe or law­ful oper­a­tion of any oth­er vehi­cle or so as to inter­fere with or to injure, dam­age, or endan­ger per­sons or prop­er­ty engaged in the law­ful use of the street.

(B) Drag Rac­ing Unlaw­ful.  No per­son shall be a par­tic­i­pant in drag rac­ing as defined in Sec­tion 5/11–504 of the Illi­nois Com­piled Statutes.

(C) Flee­ing or Attempt­ing to Elude Police Offi­cer.  Any dri­ver or oper­a­tor of a motor vehi­cle who, hav­ing been giv­en a visu­al or audi­ble sig­nal by a police offi­cer direct­ing such dri­ver or oper­a­tor to bring his vehi­cle to a stop, will­ful­ly fails to or refus­es to obey such direc­tion, increas­es his speed, extin­guish­es his lights or oth­er­wise flees or attempts to elude the offi­cer is guilty of a vio­la­tion of this Chap­ter.  The sig­nal giv­en by the police offi­cer may be by hand, voice, siren, red or blue light.  Pro­vid­ed, how­ev­er, the offi­cer giv­ing such sig­nal shall be in a peace officer’s uni­form and if dri­ving a vehi­cle, such vehi­cle shall be marked show­ing it to be an offi­cial emer­gency vehicle.

(D) Unlaw­ful Pos­ses­sion of High­way Sign or Mark­er.  The Depart­ment of Local Author­i­ties with ref­er­ence to traf­f­ic-con­trol sig­nals, signs or mark­ers owned by the Depart­ment of Local Author­i­ties are autho­rized to indi­cate the own­er­ship of such signs, sig­nals or mark­ers on the back of such devices in let­ters not less than three-eighths of an inch (3/8″) or more than three-fourths of an inch (3/4″) in height, by use of a met­al stamp, etch­ing or oth­er per­ma­nent means and except for employ­ees of the Depart­ment, deputy sher­iffs, con­trac­tors and their employ­ees engaged in high­way con­struc­tion, con­tract or work on the high­way approved by the Depart­ment, it is a vio­la­tion of this Chap­ter for any per­son to pos­sess such sign, sig­nal or mark­er so iden­ti­fied. (See 625 ILCS Sec. 5/11–313)

(E) Spe­cial Speed Lim­i­ta­tions on Ele­vat­ed Struc­tures.  No per­son shall dri­ve a vehi­cle over any bridge or oth­er ele­vat­ed struc­ture con­sti­tut­ing a part of a high­way at a speed which is greater than the max­i­mum speed which can be main­tained with safe­ty to such bridge or struc­ture when such struc­ture is sign-posted.

Upon the tri­al of any per­son charged with the vio­la­tion of this Sec­tion, proof of the deter­mi­na­tion of the max­i­mum speed by the Coun­ty and the exis­tence of such signs is con­clu­sive evi­dence of the max­i­mum speed which can be main­tained with safe­ty to such bridge or struc­ture. (See 625 ILCS Sec. 5/11–608)

(F) Gen­er­al Speed Restric­tions.  The speed lim­its on the var­i­ous streets shall be approved by the Coun­ty Board, but shall not exceed twen­ty miles per hour (20 MPH) in a school zone and not to exceed twen­­ty-five miles per hour (25 MPH) on a res­i­den­tial street, unless oth­er­wise post­ed.  (Sched­ule “C” shall be an inte­gral part of this Sec­tion.)  (See 625 ILCS Sec. 5/11–604)

(G) Spe­cial Speed Lim­it While Pass­ing Schools.  No per­son shall dri­ve a motor vehi­cle at a speed in excess of twen­ty miles per hour (20 MPH) while pass­ing a school zone or while trav­el­ing upon any pub­lic thor­ough­fare on or across which chil­dren pass going to and from school dur­ing school days when school chil­dren are present.

This Sec­tion shall not be applic­a­ble unless appro­pri­ate signs are post­ed upon streets and main­tained by the Coun­ty or State where­in the school zone is locat­ed. (See 625 ILCS Sec. 5/11–605)

(H) Fail­ure to Reduce Speed.  A vehi­cle shall be dri­ven upon the streets and roads of this Coun­ty at a speed which is rea­son­able and prop­er with regard to traf­fic con­di­tions and the use of the street or roads.  The fact that the vehi­cle does not exceed the applic­a­ble max­i­mum speed lim­it does not relieve the dri­ver of the duty to decrease speed when approach­ing and cross­ing an inter­sec­tion or when spe­cial haz­ard exists with respect to pedes­tri­an or oth­er traf­fic or by rea­son of weath­er or high­way con­di­tions.  Speed must be decreased as may be nec­es­sary to avoid col­lid­ing with any per­son or vehi­cle on or enter­ing the high­way in com­pli­ance with legal require­ments and it is the duty of all per­sons to use due care.

(I) Traf­fic Lane Usage.  When­ev­er any road­way with­in the Coun­ty has been divid­ed into two (2) or more clear­ly marked lanes for traf­fic, a vehi­cle shall be dri­ven as near­ly as prac­ti­ca­ble entire­ly with­in a sin­gle lane and shall not be moved from such lane until the dri­ver has first ascer­tained that such move­ment can be made with safety.

(J)  U‑Turns Pro­hib­it­ed.  No dri­ver of a vehi­cle shall make a “U‑turn” on any street or at any inter­sec­tion of any streets or roads in the County.

(K) Traf­fic Lane.  A vehi­cle shall be dri­ven with­in the bound­aries of the traf­fic lane that the dri­ver is using.
