Ticket Crushers
A California Vehicle Code 22350 ticket is not simply a claim that you drove faster than the number on a sign. It alleges that your speed was unreasonable or unsafe for the conditions that existed at that moment. That condition-specific standard creates important questions about the officer’s observations, the speed measurement, traffic flow, weather, visibility, roadway design, and the engineering basis for the posted limit.
At Ticket Crushers, A Law Corporation, San Francisco speeding ticket attorney Adam Cohen defends drivers cited under California’s Basic Speed Law. Our team reviews the officer’s observations, the method used to measure speed, and the conditions present at the time of the stop. We also determine whether an engineering and traffic survey or other evidence can support a defense. With flat-rate pricing starting at $149, we provide experienced representation designed to help drivers protect their records and avoid unnecessary penalties. Call (628) 203-1868 for a consultation.
After a DUI arrest, you only have ten (10) days to request a DMV hearing to contest the administrative suspension of your driver’s license. If you fail to act, then the administrative suspension of your driver’s license will start 30 days after your arrest. Call us to find out more about hiring an attorney who can immediately demand your DMV hearing.

What Does California Vehicle Code 22350 Require?
California Vehicle Code §§ 22350-22351 establish the Basic Speed Law and the related evidentiary presumptions. Section 22350 prohibits driving faster than is reasonable or prudent in light of weather, visibility, traffic, the surface and width of the highway, and other conditions. It also prohibits a speed that endangers people or property.
The key issue is safety under the actual circumstances. A driver may be cited while traveling below the posted limit if the officer believes that rain, fog, congestion, a blind curve, road work, pedestrians, or another condition made that speed unsafe. Conversely, the defense may present competent evidence that a speed above a prima facie limit did not violate the Basic Speed Law under the conditions that existed.
The “Reasonable and Prudent” Standard
“Reasonable and prudent” is not a fixed number. It asks what a careful driver could reasonably do on that roadway at that time. The analysis should therefore be tied to specific facts, not a conclusory statement that the vehicle was moving too fast.
For example, the same speed may be reasonable on a dry, open road with light traffic and unreasonable on that road during heavy rain or near a crowded crosswalk. A strong defense separates the officer’s measured or estimated speed from the separate question of whether that speed was unsafe.
Posted, Prima Facie, and Maximum Limits
Posted speed limits matter, but they do not always decide a CVC 22350 case by themselves. Under section 22351, driving at or below an applicable prima facie limit is generally lawful unless the prosecution clearly proves that the speed violated the Basic Speed Law. Driving above a prima facie limit is prima facie unlawful, but the driver may offer competent evidence that the speed was nevertheless reasonable and prudent and did not endanger people or property.
Prima facie limits should not be confused with California’s maximum-speed laws. Provisions such as CVC 22349 and CVC 22356 generally establish 65 mph or posted 70 mph maximum limits on applicable highways. Evidence that conditions were clear and traffic was light does not, by itself, rebut an alleged violation of an absolute maximum limit. The code section shown on the citation therefore matters.
These distinctions are why a defense should examine the whole record rather than treating the number on the citation as the end of the analysis.

How Do Officers Decide That a Speed Was Unsafe?
An officer may use radar, lidar, pacing, a visual estimate, or a combination of methods. The citation may also describe traffic density, roadway conditions, visibility, nearby pedestrians, a curve or grade, or the distance between the vehicle and other traffic.
Radar and lidar evidence may turn on device operation, testing, aiming, target identification, and the officer’s location. A radar beam can cover more than one vehicle, making surrounding traffic and the relative size and position of nearby vehicles relevant to target identification. Lidar is narrower, but aiming stability and movement of the beam across the vehicle can still affect how a reading should be evaluated.
A pacing case may depend on whether the officer maintained a reasonably constant distance for a sufficient period. Acceleration to catch up is different from a steady pace, and intervening traffic, changes in following distance, and the patrol vehicle’s speedometer may all matter. A visual estimate can be tested against the officer’s vantage point, distance, obstructions, and opportunity to observe.
Even an accurate speed reading does not automatically prove that the speed was unreasonable for conditions. The prosecution must still connect the reading to the elements of the charged offense.
Conditions That Can Affect a CVC 22350 Case
A court may consider how specific conditions interacted at the exact time and place of the stop. A useful defense connects each condition to objective evidence rather than relying on a general claim that the road felt safe.
Weather and Visibility
Rain, fog, glare, darkness, smoke, and wet pavement can support an allegation that a lower speed was required. They can also be overstated. Time-stamped photographs, dashcam footage, weather records, street lighting, sight-distance evidence, and the officer’s exact location may show that visibility and traction were better than the citation suggests.
Traffic Flow and the Prevailing Speed
Traffic Flow and the Prevailing Speed: The normal flow of traffic can be relevant to what reasonable drivers were doing, especially when an engineering and traffic survey is involved. Traditionally, state guidance prioritized prevailing speeds to set speed limits. However, California Assembly Bill 43 (AB 43) updated these rules to give local jurisdictions authority to lower speed limits in safety corridors, business activity districts, and school zones regardless of 85th-percentile traffic averages. Matching surrounding traffic is not an automatic defense. A court can still find that the flow itself was unsafe or that the cited driver created a distinct risk. But evidence about traffic density, lane position, spacing, and the speeds of other vehicles can help test whether the officer’s conclusion fairly reflects the conditions.
Roadway Design, Surface, Collision History, and Land Use
Road width, curves, grades, pavement condition, driveways, intersections, schools, business or residential density, bicycle and pedestrian activity, and hazards not readily apparent to a driver can all matter. Engineering and traffic surveys may also consider collision history and traffic or roadside conditions. The defense can compare those documented conditions with what was actually present when the citation was issued.
Speed-Limit Changes and Short Zones
California traffic-engineering guidance says speed-zone changes should be coordinated with changes in roadway conditions or roadside development. It also advises against unusually short zones: generally less than 0.5 mile in rural locations or 0.25 mile in urban locations, as well as short transition zones.
A short or abrupt zone does not create an automatic dismissal. It can, however, justify a closer look at signs, the transition point, the survey, the officer’s location, and whether the cited speed was measured inside the correct zone.
Key Takeaway: A VC 22350 citation is based on more than the number shown on a radar or lidar device. Courts also consider the surrounding driving conditions, and objective evidence can help demonstrate that your speed was reasonable under the circumstances.

Personally, I had a good experience. They solved my case pretty quick. I know the holidays got in the way my case was from last year around November from correct but they were able to get it done and no points. No tickets. Nothing owed. Thank you guys

Wow! These folks are impressive. They invisibly took care of my Traffic Ticket. A very pleasant experience dealing with them. There was a change of date for court appearance and I didn’t have to bother them. When the ticket was settled, they informed me and all was taken care of! Happy ending for me.

What Is an Engineering and Traffic Survey?
An engineering and traffic survey (E&TS) is the technical record used to support many posted speed limits. Caltrans explains that these surveys consider prevailing speeds, collision history, and highway, traffic, and roadside conditions not readily apparent to drivers. Business or residential density and the safety of pedestrians and bicyclists are also considered.
While the 85th-percentile speed remains a traditional baseline, modern state law (AB 43) allows local authorities to lower speed limits in high-risk zones without relying solely on traffic speeds. In addition, under California Vehicle Code § 40802, traffic surveys remain valid for up to 14 years if a registered engineer evaluates the location and determines that no major roadway changes have occurred. The key legal questions in court are whether a survey was required, whether it was valid and current, and whether the prosecution can lay the required foundation for speed-measurement evidence.
When Can a California Speed-Trap Defense Apply?
California Vehicle Code § 40802 defines prohibited speed traps and addresses radar or other electronic speed enforcement on certain roads when the prima facie limit is not justified by a qualifying engineering and traffic survey. Related statutes govern the prosecution’s proof and the use of evidence obtained through an unlawful speed trap.
A speed trap defense is technical and fact-specific. It does not apply to every speeding citation, every roadway, or every measurement method. A lawyer may review the road classification, the charged code section, the posted limit, the survey date and contents, the enforcement method, and the officer’s training and equipment records before deciding whether to raise it.

Common Defenses to a CVC 22350 Ticket
The most useful defense depends on the citation and the available evidence. Potential issues include:
- The speed was reasonable and prudent for the actual weather, visibility, traffic, and roadway conditions.
- The officer did not identify a concrete danger to people or property or relied on an incomplete description of the scene.
- Radar, lidar, pacing, or visual estimation evidence is unreliable, unsupported, or attributed to the wrong vehicle.
- The engineering and traffic survey does not support the enforcement or the prosecution cannot establish the required foundation.
- Signs, zone boundaries, or the officer’s measurement location create a material factual dispute.
- An emergency or necessity affected the driver’s conduct, supported by credible evidence.
If you believe your ticket resulted from an illegal speed trap, attorney Adam Cohen can review the circumstances of your citation and determine whether this defense applies to your case. Call Ticket Crushers, A Law Corporation’s San Francisco office at (628) 203-1868 today for a free consultation.
Evidence That Can Help Fight the Ticket
Useful evidence can disappear quickly. Preserve what is available and avoid changing original files. Depending on the case, helpful material may include:
- The citation, courtesy notice, and any notes made immediately after the stop.
- Dashcam or phone video, original photographs, and a diagram of the roadway and the officer’s position.
- Weather, visibility, traffic, and road condition records for the time and location of the stop.
- Witness statements describing traffic flow, lane position, spacing, or surrounding conditions.
- The applicable engineering and traffic survey, speed-zone map, and sign locations.
- Records relevant to the officer’s measurement method, including device testing or calibration, training, and patrol vehicle speedometer issues where applicable.
A defense lawyer can help decide which records are legally material and how to request, authenticate, and present them.
What to Do During and After a VC 22350 Stop
Pull over safely, remain polite, and avoid guessing or volunteering a speed. Arguing the case on the roadside rarely helps. Signing the citation generally acknowledges receipt and a promise to respond; it is not ordinarily an admission that the allegation is true.
As soon as practical, write down the officer’s location, traffic flow, lane position, weather, visibility, signs, nearby vehicles, and anything said during the stop. Preserve dashcam footage before it is overwritten and keep original photographs or video unchanged. These contemporaneous details may later help test the citation against the actual conditions.

Penalties, DMV Points, and Traffic School
A CVC 22350 violation is generally an infraction. A conviction ordinarily carries one negligent-operator point. The base fine commonly depends on how far above the limit the alleged speed was, while statutory assessments and court fees can raise the amount substantially. The amount on the court’s courtesy notice controls the immediate payment or bail requirement; it may differ by case and court.
For a standard Class C driver, accumulating four points in 12 months, six points in 24 months, or eight points in 36 months can support negligent-operator action by the DMV. Different rules may apply to provisional or commercial drivers. Even one point may affect insurance costs, although the amount varies by driver and insurer.
Traffic school may keep an eligible one-point violation confidential from insurers for a driver with a noncommercial license, but it does not erase the conviction or the court fine. California Courts guidance explains that clerk-approved eligibility usually requires a valid license, a noncommercial vehicle, and no traffic school attendance for another citation issued within the prior 18 months. Rules also restrict clerk approval for certain offenses, commercial vehicle cases, and speeds more than 25 mph over the limit, although a judge may have discretion in some circumstances.
| Alleged Speed Above the Applicable Limit | Base Fine | Typical Total Bail | DMV Points |
|---|---|---|---|
| 1 to 15 mph over | $35 | $234 | 1 |
| 16 to 25 mph over | $70 | $363 | 1 |
| 26 mph or more over | $100 | $486 | 1 |
Alleged speeds over 100 mph can trigger a separate charge under CVC 22348(b) with more serious consequences. A citation may list more than one violation, so the defense should be based on every charge shown on the ticket.
Key Takeaway: While the financial penalties for a VC 22350 conviction can be significant, the long-term effects of a DMV point, including higher insurance costs and the risk of license suspension, are often the greater concern.
Every speeding case is different, and the best defense depends on the facts surrounding the stop. Contact Ticket Crushers, A Law Corporation’s San Francisco office at (628) 203-1868 to schedule a free consultation.
Ways to Contest a California Speeding Ticket
Depending on the court and the charge, a driver may contest the case at a court trial or request a trial by written declaration. California Courts explain that a written declaration lets the driver submit a statement and evidence without appearing in person; the citing officer may also submit a declaration, and a judicial officer decides the case. The court’s notice and local instructions control eligibility, deadlines, forms, and any required bail deposit.
A driver who receives an unfavorable decision after a traditional trial by written declaration may be able to request a new in-person trial, called a trial de novo. It is a new trial rather than an appeal, and availability depends on the procedure used, the court’s rules, and a timely request after the decision.
Paying the amount due without contesting the citation generally results in a conviction. Missing the response date can create additional problems. Before choosing a procedure, consider the strength of the evidence, the time available to obtain records, traffic school eligibility, and whether live testimony or cross-examination may matter.
A strong defense often begins with a careful review of the evidence, not just the citation itself. To discuss your speeding ticket and possible defense strategies, call Ticket Crushers, A Law Corporation’s San Francisco office at (628) 203-1868 for a free consultation.

Frequently Asked Questions
Can I violate CVC 22350 while driving below the posted limit?
Yes. If conditions make that speed unreasonable or unsafe, a below-limit speed can violate the Basic Speed Law. The prosecution must prove the violation based on the circumstances.
Is driving with the flow of traffic a defense?
It can be relevant evidence, but it is not a complete defense by itself. The court still considers whether your speed was reasonable and whether it endangered people or property.
Does an officer need radar or lidar to issue the ticket?
No. Officers may rely on pacing or a visual estimate, sometimes combined with other observations. The reliability and foundation of the chosen method can still be challenged.
Can I request the engineering and traffic survey?
Often, yes. The responsible public agency may provide the survey, and it may also appear in the prosecution’s speed-enforcement evidence. Whether the survey is legally required and how it affects the case depend on the roadway, speed limit, and enforcement method.
Will a CVC 22350 conviction add a DMV point?
A standard conviction ordinarily adds one negligent-operator point. Traffic school can make an eligible conviction confidential from insurers, but it does not eliminate the court disposition.
Do I have to appear in court?
Not always. Some cases can be handled through counsel or by a trial by written declaration, subject to court rules and the facts of the citation. Follow the deadline and instructions on the notice unless the court or your attorney confirms a different procedure.
Should I pay the ticket before speaking with a lawyer?
Payment without a contest generally results in a conviction. If you are considering a defense, review the citation and deadline promptly so you do not give up an available option by waiting.
