Driving 120 mph is not automatically a felony in most of the United States. Based on speed alone, it is almost always charged as reckless driving, a misdemeanor that can still carry up to a year in jail. The charge crosses into felony territory when something else is layered on top: a serious injury or death, fleeing from police, driving under the influence, a prior reckless driving conviction, or participation in a street race. At 120 mph, those aggravating factors show up often enough that treating the question as a simple yes-or-no understates the risk.
What Turns 120 MPH Into a Felony
Speed by itself rarely gets you a felony. The surrounding circumstances do. These are the common paths from a misdemeanor reckless driving charge to felony exposure:
- Causing serious injury or death. This is the most common route. Reckless driving that results in great bodily harm or a fatality is routinely charged as a felony, with prison sentences ranging from one to fifteen years depending on the state and the severity of the outcome.
- Fleeing from police. If an officer activates lights and sirens and you keep going at 120 mph, prosecutors can add eluding or fleeing charges. In most states, fleeing police at high speed is a standalone felony that carries its own prison sentence on top of the reckless driving charge.
- Driving under the influence. Combining extreme speed with alcohol or drugs almost guarantees felony-level charges. Many states treat DUI with reckless driving as an aggravated offense, and the speed itself becomes powerful evidence of recklessness.
- Prior convictions. A second or third reckless driving conviction within a certain period can be elevated to a felony in several states. One prior on your record dramatically increases the chance of felony charges after a 120 mph stop.
- Street racing. Prosecutors can charge extreme speed as participation in a speed contest even without another vehicle visibly racing alongside. A growing number of states have made street racing a felony.
Someone doing 120 mph is also statistically more likely to encounter one of these aggravators than someone doing 85. The faster you go, the more likely a crash, the harder it is to stop for police, and the stronger a prosecutor’s argument that you showed willful disregard for human life.
How States Treat Extreme Speed by Itself
Even without any aggravator, 120 mph is far beyond ordinary speeding. A number of states have hard speed thresholds that automatically trigger a reckless driving charge, with no additional proof of dangerous behavior required. Those thresholds range from as low as 80 mph on some roads up to 100 mph. At 120, you clear every automatic trigger on the books. In states without a fixed threshold, driving 70 or more miles per hour over a typical highway limit gives any officer and prosecutor more than enough basis to charge reckless driving based on the circumstances.
A smaller group of states has created separate “super speeder” or aggravated speeding categories that add fines and penalties when a driver exceeds specific speeds. These don’t necessarily change the criminal classification, but they stack extra financial and administrative consequences on top of whatever criminal charge applies.
What a Misdemeanor Reckless Driving Conviction Actually Costs
Even when 120 mph stays at the misdemeanor level, reckless driving is a criminal offense, not a traffic infraction. A conviction creates a criminal record.
Jail sentences for a first-offense reckless driving conviction range widely by state. Some states cap it at 30 days, others allow up to 90 days, and a significant number authorize up to one year in county jail. At 120 mph, judges tend to sentence toward the higher end of whatever range applies. Fines typically run from several hundred to several thousand dollars before court costs and surcharges, which commonly add another $70 to $500 or more on top of the base fine.
License suspension is nearly guaranteed. Depending on the state, a reckless driving conviction can result in suspension for 30 days to a year or more, and some states impose mandatory suspension periods that judges cannot waive. Reinstatement usually requires a separate fee and sometimes completion of a defensive driving course.
Private defense counsel for a reckless driving case typically charges $1,000 to $10,000, with the higher end applying to trials or felony cases. Paying the citation without seeing a lawyer is generally not an option, because paying a reckless driving ticket is typically an admission of guilt to a criminal charge.
Insurance and SR-22 Consequences
A reckless driving conviction hits auto insurance harder than almost any other moving violation. Industry data shows average premium increases of roughly 50 to 60 percent. On a policy that costs $1,500 per year, that works out to an additional $750 to $900 annually, and the surcharge typically stays on your record for three to five years. Some insurers will drop you entirely, forcing you into a high-risk pool where rates run dramatically higher.
Many states also require an SR-22 or FR-44 certificate of financial responsibility after a reckless driving conviction. This is proof that you carry at least the state-minimum coverage, and the filing requirement often lasts three years. Letting an SR-22 lapse, even briefly, can trigger an automatic license suspension.
If You Hold a Commercial Driver’s License
CDL holders face a separate federal layer. Federal law defines both “excessive speeding” (15 mph or more over the limit) and “reckless driving” as serious traffic violations for CDL holders.1Office of the Law Revision Counsel. United States Code Title 49 Section 31301 – Definitions At 120 mph, you likely trigger both categories simultaneously.
Two serious traffic violations within a three-year period result in a minimum 60-day CDL disqualification. A third within that window extends it to at least 120 days.2GovInfo. United States Code Title 49 Section 31310 Those disqualifications apply even if the violation happened in a personal vehicle, as long as the conviction leads to a suspension or revocation of your driving privileges.3eCFR. 49 CFR 383.51 – Disqualification of Drivers
For professional drivers, the practical consequences go further than the federal disqualification. Many trucking companies and delivery services terminate drivers after any reckless driving conviction because their insurance carriers demand it. Rideshare companies and other employers that require driving typically run regular background checks and deactivate drivers with reckless driving convictions.
The Criminal Record Problem
Because reckless driving is a criminal offense, a conviction shows up on background checks for employment, housing, professional licensing, and security clearances. For jobs that involve driving, it is often an automatic disqualifier. The impact extends beyond driving-related work: any position that requires a clean criminal record or involves a background check can be affected.
Expungement is possible in some states but far from guaranteed. Some allow expungement of misdemeanor reckless driving after a waiting period; others only permit it if adjudication was withheld or the case was dismissed. If the charge was elevated to a felony, expungement becomes significantly harder, and some states prohibit it entirely for felony convictions.
If the Stop Happened on Federal Land
One scenario people overlook. On National Park Service land, military bases, and other federal property, state traffic law doesn’t apply in the usual way. Reckless driving in a national park is defined and prosecuted under state law but through the federal court system.4eCFR. 36 CFR 4.22 – Unsafe Operation A federal conviction can carry different collateral consequences than a state conviction, including complications for federal employment and security clearances. Military personnel caught at extreme speeds on base face additional consequences under the Uniform Code of Military Justice on top of any traffic charges.
What to Do If You’ve Already Been Cited
Hire a criminal defense attorney before your court date. An experienced attorney may be able to negotiate the charge down to a lesser offense, argue for reduced penalties, or challenge the speed measurement itself. Do not ignore the court date. Failure to appear on a reckless driving charge can result in a bench warrant, automatic license suspension, and additional criminal charges on top of what you already face.
