CVC 22406: Commercial Vehicle Speed Limit Ticket in California

What is CVC 22406?

California Vehicle Code Section 22406 establishes a maximum speed limit of 55 mph for commercial vehicles on California highways. This law applies to trucks, truck tractors, buses, and any vehicle transporting explosives or flammable liquids. The speed limit is lower than the standard passenger vehicle limit to account for the increased stopping distance, weight, and handling characteristics of commercial vehicles.

If you received a citation for CVC 22406, the officer determined you were operating a commercial vehicle at a speed exceeding 55 mph. This violation applies regardless of the posted speed limit for passenger vehicles on the same roadway.

Who Does This Law Apply To?

CVC 22406 specifically applies to:

• Trucks or truck tractors having three or more axles or any truck tractor drawing any other vehicle
• Vehicles transporting explosives
• Vehicles transporting flammable liquids in bulk
• Buses transporting passengers for hire, compensation, or profit
• School buses transporting students
• Farm labor vehicles transporting passengers

If you were driving a pickup truck for personal use, a standard passenger vehicle, or a light commercial van under certain weight thresholds, this code may not apply to you. The vehicle classification matters significantly.

Understanding Your Citation

When you receive a CVC 22406 ticket, check these details carefully:

Vehicle Classification: Verify the officer correctly identified your vehicle as commercial. Check the citation for how your vehicle is described. If you were driving a personal vehicle or a light-duty truck not used for commercial purposes, the citation may be incorrect.

Recorded Speed: The citation should show the speed the officer measured and the applicable speed limit. For CVC 22406, the limit is 55 mph regardless of what passenger vehicles may legally travel.

Location: Note the exact location where the violation occurred. Some areas have additional posted restrictions that may be relevant to your defense.

Officer Information: Record the officer's name, badge number, and agency. This information is important if you contest the ticket.

Appearance Date: Your citation includes a deadline to respond. Missing this deadline can result in additional penalties, license suspension, or a warrant.

Financial Consequences

The base fine for CVC 22406 is $35, but this represents only a fraction of what you will actually pay. California adds numerous fees and assessments to traffic violations:

• State and county penalty assessments
• Court operations fees
• Criminal conviction assessments
• Emergency medical services fees
• DNA identification fund fees

Total costs typically range from $197 to $229, though amounts vary by county. Some counties charge additional local fees. If you fail to pay or appear, the court may add civil assessment fees of up to $300 and suspend your driver's license.

DMV Points and Driving Record

A CVC 22406 conviction adds 1 point to your California DMV driving record. This point remains for 36 months from the violation date. Points create several problems:

Commercial Driver's License (CDL) Holders: If you hold a CDL, points can threaten your livelihood. Accumulating points may result in license suspension or revocation. Your employer may also take action based on your driving record.

Negligent Operator Treatment System (NOTS): California uses a point system to identify negligent drivers. Accumulating 4 points in 12 months, 6 points in 24 months, or 8 points in 36 months triggers NOTS action, including license suspension.

Insurance Consequences: Insurance companies review driving records when setting rates. A speeding conviction typically increases commercial vehicle insurance premiums. The increase often lasts three years and can cost hundreds or thousands of dollars annually.

Traffic School Eligibility

Traffic school eligibility for CVC 22406 violations depends on several factors. If you hold a commercial driver's license and were driving a commercial vehicle at the time of the violation, you are generally not eligible for traffic school to mask the point. However, if you were driving a commercial vehicle with a regular Class C license, you may be eligible if:

• You have not attended traffic school for another violation within the past 18 months
• The violation did not occur in a commercial vehicle requiring a CDL
• The court grants permission

Completing traffic school prevents the point from appearing on your public driving record, which can help avoid insurance increases. The conviction still appears on your record, but without the point assessment.

Trial by Written Declaration

California allows you to contest traffic tickets through Trial by Written Declaration under CVC 40902. This process lets you submit a written defense without appearing in court. You must:

1. Submit your written statement explaining why you are not guilty
2. Pay bail (the full fine amount, refunded if you win)
3. Meet the court's deadline, typically before your appearance date
4. Wait for the court's written decision

If you lose, you can request a new trial (trial de novo) and appear in court for an in-person hearing. This gives you two opportunities to contest the citation. Trial by Written Declaration works well when you have documentary evidence like GPS records, dashcam footage, or photographs.

Evidence to Gather

Building a strong defense requires collecting evidence immediately:

Vehicle Documentation: Gather your vehicle registration, weight certificates, and any documentation showing whether your vehicle qualifies as commercial under CVC 22406. If your vehicle does not meet the definition, this is critical evidence.

Speed Measurement Evidence: If you have a GPS device, dashcam, or electronic logging device (ELD) that records speed, preserve this data. Modern commercial vehicles often have multiple systems recording speed and location.

Photographic Evidence: Return to the location and photograph the area. Document any speed limit signs, road conditions, or visibility issues. Take photos from the position where the officer was reportedly stationed.

Calibration Records: Officers use radar, lidar, or pacing to measure speed. You can request calibration records for the device used. Improperly calibrated equipment may produce inaccurate readings.

Witness Statements: If passengers or other witnesses can support your account, obtain written statements with contact information.

Logbook and Trip Records: Commercial drivers should preserve logbooks, bills of lading, and trip records showing your route and timing.

Options Before Paying

Paying the fine is equivalent to pleading guilty. Before you pay, consider these options:

Contest the Ticket: You can fight the citation in court or through Trial by Written Declaration. Contesting gives you the opportunity to present evidence and cross-examine the officer.

Request a Court Trial: You can appear in court and present your defense to a judge. This allows you to testify, present evidence, and question the citing officer.

Negotiate with the Prosecutor: In some courts, you may be able to discuss your case with a prosecutor before trial. They may offer to reduce the charge or recommend a lower fine in exchange for a guilty plea.

Seek Legal Advice: If you hold a CDL or the violation threatens your employment, consult a traffic attorney. An attorney can evaluate your case and represent you in court.

Request a Payment Plan: If you cannot afford the full fine, most courts offer payment plans. You must still address the conviction and point, but this prevents additional penalties for non-payment.

Common Defenses Explained

Vehicle Misclassification: If your vehicle does not meet the legal definition of a commercial vehicle under CVC 22406, the citation is invalid. A pickup truck used for personal transportation, even if occasionally used for work, may not qualify.

Speed Measurement Error: Radar and lidar devices require proper calibration and operation. Officers must follow specific procedures. Errors in device calibration, operation, or environmental interference can produce false readings.

Mistaken Identity: In heavy traffic, officers sometimes cite the wrong vehicle. If multiple commercial vehicles were present, the officer may have confused your vehicle with another.

Emergency Circumstances: If you exceeded the speed limit to avoid immediate danger or respond to an emergency, this may provide a defense. You must show the circumstances were genuine and that speeding was necessary.

Unclear Signage: While CVC 22406 applies statewide, confusion about applicable speed limits in construction zones or areas with multiple posted limits may support your defense.

What Happens If You Ignore the Ticket

Ignoring a traffic citation creates serious consequences:

• The court may issue a warrant for your arrest
• Your driver's license will be suspended
• The court will add a civil assessment fee of up to $300
• The DMV may place a hold on your vehicle registration
• Your employer may be notified if you hold a CDL

If you missed your court date, contact the court immediately to request relief. Courts may vacate warrants and reinstate your license if you act quickly.

Special Considerations for CDL Holders

If you hold a commercial driver's license, a CVC 22406 conviction has enhanced consequences:

Employer Notification: Many employers require immediate reporting of traffic violations. Your company may take disciplinary action regardless of the outcome.

Federal Motor Carrier Safety Regulations: Violations appear on your FMCSA record and affect your safety rating. Multiple violations can make you unemployable in the commercial driving industry.

No Traffic School: CDL holders generally cannot use traffic school to mask points when the violation occurred in a commercial vehicle.

Serious Violation: Depending on the speed, CVC 22406 violations may qualify as serious violations under federal regulations. Two serious violations in three years result in a 60-day CDL disqualification. Three violations result in 120-day disqualification.

Given these stakes, CDL holders should strongly consider consulting a traffic attorney who understands commercial driving regulations.
