A ticket for failure to yield to an emergency vehicle is a moving violation. As such, it has the potential to result in a suspended license.
The statute that governs these cases is 625 ILCS 5/11-907. The law says that on the approach of an authorized emergency vehicle making use of audible and visual signals or a police vehicle properly and lawfully making use of an audible or visual signal, all drivers shall yield the right-of-way and pull over to the right. Section 11-907(a)(1).
All drivers are required to remain in such position until emergency vehicle has passed or they are otherwise directed by a police officer. Section 11-907(a)(2).
Failure to yield to an emergency vehicle is a petty offense. It is not a crime for which the judge can sentence the defendant to jail. Rather, the court can only impose a fine and traffic school.
However, this offense is a moving violation. Therefore, a conviction can result in a suspended license. The Secretary of State is authorized to suspend the driving privileges of any person who has three convictions within any 12 month period.
