Bridges and tunnels aren’t just impressive structures — they’re also subject to special traffic laws in California. One of those is Vehicle Code § 22405 VC, which prohibits driving at unsafe speeds on bridges, elevated structures, and tunnels. Unlike general speeding laws, this law focuses on the specific safety limitations of these structures, making it more technical and situational.
If you’ve received a ticket under this code, you may be wondering what it means, how serious it is, and what you can do about it. This guide breaks it all down — from legal definitions and penalties to defense strategies and next steps — so you can make informed decisions about how to handle the citation.
What is Vehicle Code § 22405 VC?
California Vehicle Code § 22405 makes it illegal to drive on any bridge, tunnel, elevated structure, or tube at a speed that exceeds what is considered safe for that particular structure. Unlike general speed limits, the focus here is on the structural integrity and design limits of the roadway itself.
Key Takeaways:
-
Applies specifically to elevated roadways, bridges, and tunnels that are part of a public highway.
-
The maximum safe speed is determined by traffic engineers through safety evaluations.
-
Speed limits must be clearly posted within 500 feet of each end of the structure.
-
Violating this limit, even by a small margin, can result in a traffic citation.
In essence, even if you are within the general speed limit for a highway, you could still be in violation if your speed exceeds the safe limit for a bridge or tunnel.
How Are Safe Speeds Determined?
Before a speed limit can be enforced under § 22405, authorities must complete a traffic engineering study. This study considers factors such as:
-
Structural capacity of the bridge or tunnel
-
Average traffic flow and vehicle weight
-
Weather exposure and wind risks
-
Sight distance and road curvature
Once the study is complete, the speed limit must be properly posted at or near the entrance to the structure. If signs are missing, damaged, or improperly placed, that could be a strong defense against the citation.
Penalties for Violating Vehicle Code § 22405
A violation under this section is classified as a traffic infraction, but the consequences can still be significant:
-
Fines: Speeding in a restricted zone can result in fines ranging from several hundred dollars, depending on the severity of the violation.
-
DMV Points: A conviction will typically result in one point being added to your driving record.
-
Insurance Impact: Any added point may increase your insurance premium, potentially for several years.
-
Traffic School Eligibility: In many cases, you may attend traffic school to prevent the point from affecting your record, assuming you meet eligibility requirements.
-
Negligence in Civil Cases: If an accident occurs while speeding on a bridge or tunnel, a violation of this statute may be used as evidence against you in a civil lawsuit.
Common Defenses for VC § 22405 Violations
Many drivers are surprised to learn that Vehicle Code § 22405 can be successfully challenged. Common defenses include:
1. Improper or Missing Signage
If the speed limit was not clearly posted within the required distance from the structure, the citation may be invalid.
2. Safe Driving Conditions
You may argue that you were driving safely under the conditions, and that the posted speed was not clearly applicable or visible.
3. Faulty Speed Detection
Challenging the radar, lidar, or pacing method used to determine your speed can undermine the prosecution’s case.
4. No Valid Engineering Study
If the speed limit was not based on a properly conducted engineering survey, the posted speed may not be legally enforceable.
5. Emergency or Necessity
In rare cases, exceeding the speed limit may be justifiable in order to avoid a collision or respond to an emergency.
What to Do If You Receive a VC § 22405 Ticket
If you’re cited under this law, follow these steps:
-
Read the Citation Carefully
Note the exact location, speed, and code cited. -
Inspect the Area (If Safe)
Visit the bridge or tunnel to check for signs and conditions. Take pictures if necessary. -
Request Evidence
You have the right to request copies of radar logs, officer reports, and the engineering study behind the posted speed. -
Check Eligibility for Traffic School
If you qualify, this can prevent points from affecting your record. -
Consult a Traffic Attorney
An experienced traffic defense lawyer can help you assess the situation and recommend the best course of action — whether it’s fighting the charge or seeking a reduction.
Frequently Asked Questions
Is this violation a criminal offense?
No. It is considered a traffic infraction, not a criminal charge.
How many points will I get?
Generally, a violation adds one point to your driving record.
Can I go to traffic school for this?
Yes, if you’re eligible. It depends on your driving history, the nature of the offense, and the court’s policies.
Will this affect my insurance?
Possibly. Any point on your record can trigger an increase in your premiums.
Can the violation be dismissed?
Yes, particularly if signage or legal procedures weren’t properly followed.
Why This Law Exists
The goal of VC § 22405 is to protect drivers and maintain the integrity of critical infrastructure. Bridges and tunnels have unique engineering constraints. Excessive speeds can increase the risk of damage or collapse, especially in high-traffic or weather-sensitive areas.
However, not every ticket issued under this statute is fair or legally sound. Many citations are dismissed or reduced when challenged effectively — especially with legal support.
