Former Cook County Felony Prosecutor
Aggravated Speeding Lawyer Chicago
Experienced Chicago Aggravated Speeding Lawyer Defending Criminal Traffic Charges
Many drivers are shocked to learn that aggravated speeding is not simply a traffic ticket under Illinois law. Unlike most traffic violations, aggravated speeding is a criminal offense that can result in jail time, a permanent criminal record, driver’s license consequences, increased insurance premiums, and significant long-term consequences affecting both personal and professional life.
If you have been charged with aggravated speeding in Chicago, Cook County, DuPage County, Lake County, or the surrounding Chicago area, experienced legal representation can make a significant difference in the outcome of your case.
Andrew M. Weisberg is a former Cook County prosecutor and experienced Chicago criminal defense attorney who has successfully represented clients charged with aggravated speeding, reckless driving, suspended license offenses, DUI-related traffic offenses, and other criminal charges throughout Illinois. As a former prosecutor, he understands how these criminal cases are investigated, prosecuted, and negotiated, and he develops defense strategies tailored to the specific circumstances of each case, including in complex DUI-related traffic offenses.
What Is Aggravated Speeding Under Illinois Law?
Most speeding tickets are considered petty traffic offenses. Aggravated speeding is different because it is a criminal offense that requires a court appearance.
Under Illinois law:
- Driving 26 to 34 miles per hour above the posted speed limit is charged as a Class B misdemeanor.
- Driving 35 miles per hour or more above the posted speed limit is charged as a Class A misdemeanor.
Unlike ordinary speeding violations, aggravated speeding creates the possibility of a criminal conviction and a permanent criminal record.
Penalties for Aggravated Speeding
Class B Misdemeanor
A driver accused of traveling 26 to 34 miles per hour above the speed limit faces:
- Up to six months in jail
- Maximum fine of $1,500
- Court costs
- Community service
- Criminal record consequences
Class A Misdemeanor
A driver accused of traveling 35 miles per hour or more above the speed limit faces:
- Up to one year in jail
- Maximum fine of $2,500
- Probation
- Court supervision in appropriate cases
- Criminal conviction consequences
The penalties for aggravated speeding vary based upon the driver’s record, the circumstances of the traffic stop, and whether aggravating factors are present such as speeding in a school zone, construction zone, or near heavy traffic.
Consequences Beyond the Courtroom
Many drivers focus on the possibility of jail time but underestimate the long-term consequences of an aggravated speeding conviction.
A conviction can negatively affect your Illinois driving record and may result in significantly higher insurance rates. Insurance companies often view aggravated speeding convictions as indicators of risky driving behavior.
Studies have shown that a single speeding ticket in Illinois can increase insurance costs by approximately $1,491 over the following three years, with some insurers increasing annual premiums by more than $700. Because aggravated speeding is a criminal traffic offense rather than a simple traffic violation, the insurance consequences can be even greater.
Traffic convictions may remain relevant to insurance companies for up to five years and can affect a driver’s ability to obtain affordable coverage.
A conviction may also create problems involving broader criminal justice issues, especially if an aggravated speeding arrest leads to additional charges or a more complicated Illinois arrest process.
- Employment opportunities
- Professional licensing
- Background checks
- Commercial driver’s license eligibility
- Security clearances
Driver’s License Consequences
A conviction for aggravated speeding can significantly impact driving privileges.
The Illinois Secretary of State reviews a driver’s overall driving record when determining whether additional action is appropriate.
Multiple moving violations accumulated during a three year period can result in a suspended or revoked driver’s license. Commercial drivers and CDL holders often face particularly serious consequences because traffic convictions may affect their ability to continue working, especially when those violations occur in Cook County and require guidance from an experienced Cook County criminal defense attorney.
Protecting your driver’s license and driving record is often one of the primary goals in defending aggravated speeding charges.
Common Defenses to Aggravated Speeding Charges
Every aggravated speeding case requires a defense strategy tailored to the facts.
An experienced attorney will carefully review all available evidence, including:
- Police reports
- Dashcam footage
- Body camera footage
- Radar readings
- Laser readings
- Witness statements
Challenging Radar and Laser Evidence
Many aggravated speeding charges depend upon radar or laser speed detection devices.
A defense attorney can challenge the accuracy of this evidence by demanding:
- Calibration records
- Maintenance logs
- Officer certification records
- Equipment testing records
If police officers failed to properly maintain or calibrate the equipment, the prosecution may have difficulty proving the alleged speed beyond a reasonable doubt.
Challenging the Traffic Stop
The police must have a lawful basis for initiating the traffic stop.
If the stop violated constitutional requirements, an attorney may file motions seeking to suppress evidence or dismiss charges.
Challenging the Alleged Speed
Speed detection equipment is not infallible. An experienced attorney may challenge:
- Improper operation of equipment
- Mechanical issues
- Environmental interference
- Inaccurate readings
- Insufficient documentation
Negotiating Reduced Charges
One of the most valuable benefits of hiring an experienced traffic defense attorney is the ability to negotiate with prosecutors and address any related criminal charges that may arise from the same incident, such as resisting or obstructing arrest.
Depending on the facts of the case, an attorney may be able to obtain:
- Reduced charges
- A civil speeding ticket
- A petty traffic offense
- Court supervision
- Other favorable resolutions
Reducing aggravated speeding charges to a civil traffic violation can completely eliminate the risk of a misdemeanor conviction.
Court Supervision
For many first offense defendants with a clean driving record, court supervision may be available.
Court supervision is often the best possible result because successful completion generally means:
- No criminal conviction
- No permanent criminal record
- Case successfully completed without a conviction being entered
Securing court supervision can help protect future employment opportunities, professional licenses, and insurance rates, benefits that are often highlighted in client reviews of Andrew M. Weisberg’s representation.
Why Hiring an Experienced Aggravated Speeding Lawyer Matters
Without legal representation, individuals charged with aggravated speeding are far more likely to suffer the consequences of a criminal conviction.
An experienced attorney understands local court dynamics, prosecutor expectations, and the procedures commonly used in Cook County, DuPage County, and Lake County courts.
Legal representation can significantly impact the outcome of aggravated speeding cases by:
- Challenging weak evidence
- Negotiating reduced charges
- Seeking court supervision
- Protecting driving privileges
- Avoiding a permanent criminal record
As a former Cook County prosecutor, Andrew M. Weisberg understands how these cases are prosecuted and how to pursue the strongest defense possible.
