Driving faster than 100 mph on a California highway is an infraction under Vehicle Code Section 22348(b), and the penalties include base fines of up to $1,000, total costs that commonly exceed $2,000 after mandatory surcharges, two points on your driving record, and a license suspension that is discretionary for a first offense but mandatory for repeats. One quick clarification before going further: subdivision (c) of the same statute deals with lane requirements for large commercial vehicles, not speeding, so if your ticket is for going over 100 mph, subdivision (b) is what applies.1California Legislative Information.

Fines and What You Will Actually Pay
Base fines climb with each repeat conviction:
- First offense: up to $500
- Second offense within three years: up to $750
- Third offense within five years of two or more prior convictions: up to $1,000
Those numbers are only the starting point. California stacks penalty assessments and surcharges on every traffic fine. For every $10 of the base fine, the state adds between $22 and $29 in additional penalties, then layers a 20 percent surcharge on the base fine itself, plus fixed court fees. A $500 base fine typically lands somewhere between $1,800 and $2,500 by the time you pay. A $1,000 base fine for a third offense can push past $3,000. Miss the 20-day payment window and a 50 percent late charge gets added to any unpaid penalties.2California Courts. Uniform Bail and Penalty Schedules
License Suspension by Offense Number
Suspension rules depend heavily on whether this is your first conviction or a repeat, and repeats take the decision away from the judge.
First Offense
The court has discretion to suspend your license for up to 30 days, but is not required to do so.3California Legislative Information. California Vehicle Code 13200.5 – Court Suspension Authority Some judges impose the full 30 days, others impose none, particularly when the driver has an otherwise clean record. There is no restricted-license option written into the first-offense statute, so if the judge suspends, you lose driving privileges entirely for the suspension period.
Second Offense Within Three Years
A second conviction within three years of a prior 22348(b) offense removes judicial discretion. The DMV must either suspend your license for six months or restrict it for six months to travel between home and work only.4California Legislative Information. California Vehicle Code 13355 – Suspension for Excessive Speed
Third Offense Within Five Years
A third conviction within five years of two or more prior 22348(b) offenses results in either a one-year suspension or a one-year restriction to work-related travel only.4California Legislative Information. California Vehicle Code 13355 – Suspension for Excessive Speed The DMV imposes it automatically on conviction.
Two Points on Your Record
A conviction adds two points to your California driving record.5California Legislative Information. California Vehicle Code 12810 – Violation Point Count That is double what most moving violations carry, and they hit all at once. For a Class C license holder, the DMV treats you as a negligent operator at four or more points in 12 months, six or more in 24 months, or eight or more in 36 months.6California DMV. Driver Negligence A single 22348(b) conviction gets you halfway to the 12-month threshold, and the negligent-operator process triggers its own warning letters and potential suspension on top of any suspension from the speeding conviction itself.
Why Traffic School Is Off the Table
Many drivers assume traffic school can keep the points off their record. It cannot here. California court rules prohibit traffic school for any speeding violation where the alleged speed exceeds the limit by more than 25 mph.7California Courts. Rule 4.104 – Procedures and Eligibility Criteria for Attending Traffic Violator School The maximum speed limit on any California highway is 70 mph, so a ticket for over 100 mph is always more than 25 mph over the limit. The conviction and points will be visible to your insurance company.
What This Does to Insurance
Two points from a 100-mph conviction will get your insurer’s attention. Exact increases depend on your carrier, driving history, and coverage levels, but insurers treat high-speed violations as serious risk indicators. Expect a significant premium increase lasting three to five years, since that is how long most California insurers look back when calculating rates. Drivers with otherwise clean records absorb the hit more easily than those with prior violations, but the increase is rarely trivial for anyone.
Possible Defenses
Fighting a 100-mph ticket is harder than fighting a routine speeding citation, but it is not hopeless. The strongest defenses focus on whether the prosecution can actually prove the speed.
Speed Measurement
Radar and lidar require regular calibration to produce reliable readings. Through pretrial discovery, your attorney can obtain the calibration and maintenance logs for the specific device used during your stop. If the logs show the device was overdue for calibration, was not tested to the manufacturer’s schedule, or produced inconsistent results at its last certification, the reading becomes vulnerable to challenge. The operating officer also needs current training and certification on that specific model. Gaps in either record can undermine the prosecution’s evidence.
Necessity
California recognizes a necessity defense when a driver can show they exceeded the speed limit to avoid a greater immediate danger, such as accelerating to avoid a collision or to reach emergency medical care. This defense requires concrete evidence like witness statements, dashcam footage, or medical records, and courts apply it narrowly. A vague claim that traffic “felt unsafe” will not clear the bar. You need to show a specific, imminent threat that left you no reasonable alternative.
Speedometer Calibration
If your speedometer was malfunctioning and you genuinely did not know you were over 100 mph, that fact can be useful, though more for negotiating a reduction than winning an outright dismissal. Having your speedometer independently tested after the citation and presenting the results to the court shows good faith and may persuade a judge to reduce the charge to a standard speeding violation with lower penalties.
How Reckless Driving Fits In
Driving over 100 mph does not automatically become a reckless driving charge under Vehicle Code 23103, but prosecutors and officers have discretion to add it, particularly with aggravating factors like weaving through traffic, driving on the shoulder, or nearly causing a collision. A reckless driving conviction is a misdemeanor and carries potential jail time, which makes it a fundamentally different situation than the 22348(b) infraction. The relationship can also work in a defendant’s favor: an attorney may negotiate a plea from 22348(b) down to a basic speeding infraction, or from a reckless driving charge down to 22348(b), depending on the facts and the driver’s history.
