CVC 22400 Ticket in California | Minimum Speed Violation Guide

What is California Vehicle Code 22400?

California Vehicle Code Section 22400 addresses driving too slowly on public highways. The law has two main parts:

CVC 22400(a) states that no person shall drive upon a highway at such a slow speed as to impede or block the normal and reasonable movement of traffic, unless the reduced speed is necessary for safe operation, because of a grade, or in compliance with law.

CVC 22400(b) requires that whenever a minimum speed limit has been established, no person shall drive slower than that minimum speed limit except when necessary for safe operation or in compliance with law.

This code exists to keep traffic flowing smoothly and safely. While speeding gets more attention, driving too slowly can also create hazardous conditions by forcing other drivers to brake suddenly, change lanes abruptly, or make unsafe passing maneuvers.

When Does CVC 22400 Apply?

This violation most commonly occurs on highways, freeways, and expressways where traffic is expected to move at higher speeds. You can receive a citation under CVC 22400 in two situations:

Impeding Traffic: You are driving significantly slower than surrounding traffic without a valid reason, causing other vehicles to slow down, queue behind you, or take evasive action.

Below Minimum Speed: You are driving below a posted minimum speed limit sign. These signs are typically found on freeways and show the lowest legal speed (often 40 or 45 mph).

The law recognizes that sometimes slow driving is necessary. You are allowed to drive below the minimum speed or slower than traffic when conditions require it for safety, such as heavy traffic, poor weather, mechanical problems, or road hazards.

What to Check on Your Citation

When you receive a CVC 22400 ticket, carefully review these details:

Violation code: Confirm it lists CVC 22400(a) or CVC 22400(b). The subsection matters because (b) involves a posted minimum speed while (a) involves impeding traffic flow.

Location: Note the exact highway, freeway, or road name and the nearest cross street or mile marker. The location helps determine whether minimum speed limits apply and what traffic conditions existed.

Time and date: Record when the citation was issued. Time of day affects traffic density, which is relevant to whether you were actually impeding traffic.

Officer's notes: Read any comments the officer wrote. These may describe your speed, traffic conditions, or the reason for the stop.

Posted speed limits: Check whether the citation mentions a minimum speed limit sign. If cited under 22400(b), the prosecution must prove a minimum speed limit was posted.

Appearance date: Note your deadline to respond. You typically have options to pay, contest, or request traffic school before this date.

Penalties and Consequences

A CVC 22400 violation is an infraction, not a criminal offense. The consequences include:

Base fine: The base fine is typically $35, but total costs are much higher after court fees, assessments, and county charges are added.

Total fine: Expect to pay between $197 and $229 or more depending on your county. Some counties add local surcharges that increase the total.

DMV points: This violation typically adds one point to your California driving record. Points remain for 36 months from the violation date.

Insurance impact: The DMV point may cause your auto insurance rates to increase. Insurance companies review driving records and often raise premiums after moving violations.

Traffic school eligibility: You may be eligible for traffic school to mask the point from your insurance company. California allows traffic school once every 18 months for eligible infractions. Completing traffic school prevents the point from appearing to insurers, though it still counts toward the 18-month interval and remains visible to the DMV and courts.

What Evidence to Gather

If you plan to contest your CVC 22400 citation, collect evidence that supports your defense:

Photographs: Take photos of the location showing road conditions, lane configurations, signage, and whether a minimum speed limit sign exists. Visit at the same time of day if possible.

Weather reports: Obtain official weather data for the date and time of your citation. Rain, fog, wind, or other conditions justify reduced speed.

Traffic conditions: Dashcam footage, if available, can show heavy traffic or congestion. Witness statements from passengers can describe traffic density.

Vehicle records: If mechanical problems caused slow driving, gather repair receipts, tow truck records, or mechanic statements documenting the issue.

Medical documentation: If a medical emergency required slow driving, obtain records that show you were transporting someone who needed care or experiencing a health issue yourself.

Speedometer evidence: If your speedometer was inaccurate, calibration records or repair documentation can support your case.

Road hazards: Document construction zones, accidents, debris, or other obstacles that required reduced speed.

Your Options Before Paying

Paying the fine is an admission of guilt. Before you pay, consider these alternatives:

Contest the citation: You have the right to challenge the ticket in court. You can request a trial and present evidence that you were not impeding traffic or that your slow speed was necessary for safety.

Trial by Written Declaration: California allows you to contest traffic tickets by mail under CVC 40902. You submit a written statement and evidence without appearing in court. The officer also submits a written response. A judge reviews both and issues a decision. If you lose, you can request a new trial in person (trial de novo).

Request traffic school: If eligible, you can attend traffic school to prevent the point from affecting your insurance. You still pay the fine plus a traffic school fee, but you avoid insurance rate increases.

Negotiate: In some courts, you may be able to meet with a prosecutor or commissioner to discuss reducing the charge or penalty, especially if you have a clean driving record.

Seek legal assistance: Traffic attorneys or legal document services like ClerkHero can help you prepare a defense, especially for Trial by Written Declaration.

Trial by Written Declaration Process

Trial by Written Declaration (TR-205) is often the most convenient way to contest a CVC 22400 ticket:

1. Request the trial: Check the box on your citation or contact the court before the deadline to request TR-205.

2. Pay bail: You must deposit the full fine amount as bail. If you win, the court refunds this amount.

3. Prepare your statement: Write a declaration explaining why you are not guilty. Attach supporting evidence like photos, weather reports, or repair records.

4. Submit by deadline: Mail your declaration and evidence to the court by the deadline, typically at least 15 days before your appearance date.

5. Officer responds: The citing officer submits their own written declaration.

6. Judge decides: A judge reviews both submissions and issues a written decision, typically within 90 days.

7. Appeal if needed: If you lose, you can request a trial de novo (new in-person trial) within 20 days of the written decision.

Common Defenses Explained

Traffic congestion: If heavy traffic forced you to drive slowly, you were not impeding traffic but rather moving with it. Evidence of traffic density at that time supports this defense.

Weather conditions: Rain, fog, ice, snow, or high winds justify reduced speed under the safety exception. Official weather reports strengthen this defense.

Road hazards: Construction zones, accidents, debris, potholes, or animals on the road are valid reasons to slow down. Photos or news reports of the hazard help prove this.

Mechanical problems: If your vehicle experienced engine trouble, overheating, transmission issues, or other mechanical failures, you may have had no choice but to drive slowly. Repair records or tow receipts support this defense.

No minimum speed sign: For CVC 22400(b) citations, the prosecution must prove a minimum speed limit was posted. If no sign existed or it was obscured, you have a strong defense.

Not impeding traffic: If you were driving in the right lane and other vehicles could easily pass, you may not have been impeding the normal flow of traffic. Lane position matters.

Medical emergency: If you or a passenger had a medical issue requiring slow, careful driving, this falls under the safety exception. Medical records can support this claim.

Speedometer malfunction: If your speedometer was broken or inaccurate, you may not have known your actual speed. This is a weaker defense but can be supported by repair records.

Key Legal Points

The prosecution must prove several elements for a CVC 22400 conviction:

You were driving on a highway: The violation applies to public highways, not private roads or parking lots.

Your speed was unreasonably slow: For 22400(a), the prosecution must show your speed impeded normal traffic flow. For 22400(b), they must show you drove below a posted minimum.

No safety justification: The prosecution must prove your slow speed was not necessary for safe operation or compliance with law.

Minimum speed sign (for 22400(b)): If cited under subsection (b), the prosecution must prove a minimum speed limit sign was properly posted and visible.

You do not have to prove your innocence. The burden is on the prosecution to prove each element beyond a reasonable doubt (for criminal matters) or by a preponderance of evidence (for infractions).

Insurance and DMV Points

The one-point assessment for CVC 22400 can affect you in several ways:

Insurance rates: Most insurance companies increase premiums after a moving violation. The increase varies by insurer but can last three years or more.

Negligent operator status: California uses a point system to identify negligent operators. Accumulating too many points can result in license suspension. You can be designated a negligent operator with four points in 12 months, six points in 24 months, or eight points in 36 months.

Traffic school benefit: Completing traffic school prevents the point from appearing to insurance companies, though the DMV and courts still see it. This can save you significant money on insurance premiums.

Point duration: Points remain on your record for 36 months from the violation date, not the conviction date.

When to Seek Legal Help

While CVC 22400 is typically a straightforward infraction, consider consulting a licensed attorney if:

You have prior violations: Multiple points on your record increase the risk of license suspension.

You hold a commercial license: CDL holders face stricter point thresholds and may have employment consequences.

The citation involves other charges: If you received multiple citations or if there were unusual circumstances, legal advice may help.

You are unsure about defenses: An attorney can evaluate your specific situation and evidence.

Frequently Asked Questions

Drivers cited under CVC 22400 commonly have questions about the process, penalties, and options. Understanding these practical issues helps you make informed decisions about how to handle your citation.

Final Considerations

A CVC 22400 citation is not a criminal matter, but it does carry financial and insurance consequences. You have the right to contest the ticket, and many drivers successfully fight these citations by showing they had valid safety reasons for driving slowly.

Review your citation carefully, gather supporting evidence, and consider your options before simply paying the fine. Trial by Written Declaration offers a convenient way to contest the ticket without missing work or appearing in court.

If you had a legitimate reason for driving slowly, document it thoroughly and present your case. California law recognizes that safety sometimes requires reduced speed, and judges consider the specific circumstances of each case.
