CVC 22350
Speeding Ticket Defense Strategies
California's basic speed law prohibits driving at a speed that is unsafe for conditions — not simply any speed above a posted limit. Understanding what the prosecution must prove gives you the foundation for an effective written declaration.
What the prosecution must prove
- You were the driver of the vehicle
- You were driving on a public roadway
- Your speed exceeded what was safe for conditions at that time and place
- The speed-measuring device (if used) was properly calibrated and operated
- A current engineering and traffic survey authorized the speed limit being enforced by radar
Each element must be established. When any element is contested with specific facts, the declaration becomes significantly stronger.
Defense strategies
Radar or laser calibration records
Speed-measuring devices must be calibrated regularly by a certified technician. Officers are required to have calibration records available. If the device was out-of-calibration tolerance, the speed reading is inadmissible. A written declaration may request that the agency produce these records; when the agency cannot provide them, the reading lacks evidentiary foundation.
No current speed trap survey
Under California Vehicle Code §40802, radar cannot be used to enforce a speed limit unless the limit was set based on an engineering and traffic survey conducted within the past 5 years (7 years in some cases). Many posted limits are set without a current survey, making radar enforcement unlawful on that road segment.
Speed was safe for conditions
CVC 22350 is the basic speed law — it prohibits driving at a speed that is unsafe for conditions, not simply any speed above the posted limit. Where traffic, visibility, road conditions, and weather all supported the speed driven, the speed itself is not automatically a violation. A declaration that addresses those specific conditions in concrete detail is stronger than one that asserts the conclusion alone.
Officer's visual estimate was unreliable
When officers cite based on visual estimation rather than a device reading, the accuracy depends on training, angle of observation, and distance. A citation that relies solely on visual estimation without corroborating evidence is weaker than one backed by a calibrated device. A written response that addresses traffic density, lane position, and the officer's distance and angle of observation can raise questions about the reliability of the estimate.
Emergency or necessity
Speeding to avoid imminent danger or reach emergency medical care may constitute a legal necessity defense. This defense requires specific, documented facts — the exact nature of the emergency, why exceeding the speed limit was necessary, and why no reasonable alternative was available. General claims of urgency without supporting facts do not meet this standard.
Arguments that rarely work
- • "Everyone was going the same speed" — other drivers' violations don't excuse yours
- • "I was keeping up with traffic" — same issue as above
- • "The officer was targeting me" — selective enforcement is nearly impossible to prove in writing
- • General claims without specific facts — vague statements carry no weight
