Many people associate DUI laws with driving a car, truck, or motorcycle. California law, however, also prohibits cycling under the influence of alcohol or drugs. California Vehicle Code § 21200.5 makes it unlawful to ride a bicycle on a highway while under the influence of an alcoholic beverage, a drug, or a combination of alcohol and drugs.
A bicycle DUI is different from a traditional DUI involving a motor vehicle. California has a separate statute governing impaired bicycle riding, with its own penalty provisions and chemical-testing rules. The law also applies to qualifying electric bicycles. In addition, a 2026 California Court of Appeal decision addressed whether California’s administrative driver’s-license suspension laws apply to a person who refuses chemical testing while riding an electric bicycle.
This article explains what California Vehicle Code § 21200.5 prohibits, what penalties can apply, how chemical testing works, whether a bicycle DUI can affect a driver’s license, and how bicycle DUI law differs from the state’s ordinary motor-vehicle DUI laws.
What Is California Vehicle Code § 21200.5?
California Vehicle Code § 21200.5 is the state’s specific law addressing riding a bicycle under the influence.
The statute makes it unlawful to ride a bicycle upon a highway while under the influence of:
- An alcoholic beverage;
- Any drug; or
- A combination of an alcoholic beverage and any drug.
The statute also gives a person arrested for an alleged violation the ability to request a chemical test of their blood, breath, or urine for purposes of determining alcohol or drug content. If the person makes that request, the arresting officer must have the test performed.
A conviction under Vehicle Code § 21200.5 is punishable by a fine of no more than $250. The statute also expressly provides that violations are subject to Vehicle Code § 13202.5, which concerns certain driving-privilege consequences for people under 21.
Importantly, Vehicle Code § 40000.13 expressly classifies a violation of § 21200.5 as a misdemeanor, not an infraction.
Is It Illegal to Ride a Bicycle While Drunk in California?
Yes. California law specifically prohibits riding a bicycle on a highway while under the influence of alcohol, drugs, or both.
The fact that a bicycle is not a conventional motor vehicle does not mean that an impaired cyclist is outside the California Vehicle Code. Instead, California has a specific bicycle DUI provision.
Example
Suppose a person leaves a bar after drinking alcohol and rides a bicycle home. During the ride, the cyclist repeatedly swerves, has difficulty maintaining balance, and nearly collides with another road user.
The fact that the person is riding a bicycle rather than driving a car does not automatically make the conduct lawful. If the prosecution can establish the elements of Vehicle Code § 21200.5, the cyclist could face a bicycle DUI charge.
What Does “Under the Influence” Mean Under California Bicycle DUI Law?
Vehicle Code § 21200.5 prohibits riding a bicycle while under the influence of alcohol, a drug, or both. The statute does not establish a specific numerical blood-alcohol concentration threshold for bicycle riders.
This is an important distinction from the rules people commonly associate with California’s motor-vehicle DUI laws.
The evidence in a bicycle DUI case can vary depending on the circumstances. Potential evidence may include:
- How the cyclist was operating the bicycle;
- Physical signs observed by a law-enforcement officer;
- Statements made by the cyclist;
- Balance or coordination;
- Chemical-test results;
- Witness observations;
- Video footage; and
- Circumstances surrounding a traffic stop or collision.
The specific significance of any particular piece of evidence depends on the facts of the case.
Example of Possible Impairment Evidence
Imagine that an officer observes a cyclist repeatedly crossing into an area of opposing traffic. During the encounter, the officer also observes signs that may indicate impairment.
Those observations could potentially become evidence in a prosecution under § 21200.5.
On the other hand, the mere fact that someone consumed alcohol does not by itself establish every element of the offense. The legal issue is whether the person was riding the bicycle while under the influence as prohibited by the statute.
Does California Have a .08 BAC Limit for Bicycle DUI?
Vehicle Code § 21200.5 does not establish a .08% BAC threshold for bicycle riders.
The statute instead focuses on whether the person was under the influence while riding a bicycle on a highway.
This means cyclists should not assume that bicycle DUI law operates exactly like the BAC rules applicable to drivers of motor vehicles.
A chemical test can still be relevant evidence. However, the existence of a particular BAC number should not automatically be treated as the equivalent of a statutory .08% rule for bicycle DUI.
What Are the Penalties for Vehicle Code § 21200.5?
A conviction under Vehicle Code § 21200.5 is punishable by a fine of up to $250.
The offense is also specifically classified as a misdemeanor rather than an infraction under Vehicle Code § 40000.13.
This distinction is important. A misdemeanor is a criminal offense, even though the specific punishment authorized by § 21200.5 is limited to a fine.
Can You Go to Jail for a Bicycle DUI?
Vehicle Code § 21200.5 itself provides a maximum fine of $250 and does not authorize jail as the punishment for that particular violation. The California Court of Appeal specifically recognized this distinction in its 2026 decision in Beale v. Department of Motor Vehicles.
This does not necessarily mean that every incident involving an impaired cyclist will involve only § 21200.5. Other allegations may arise from the same incident depending on what occurred.
For example, a collision involving significant injuries or other alleged criminal conduct could present additional legal issues separate from the bicycle DUI charge.
Is a Bicycle DUI a Misdemeanor in California?
Yes. Vehicle Code § 40000.13 expressly states that a violation of Vehicle Code § 21200.5 is a misdemeanor and not an infraction.
This classification is significant because misdemeanor cases are handled differently from ordinary infractions.
For example, California courts may require a person charged with § 21200.5 to appear in court. The Superior Court of California, County of Santa Cruz, specifically lists § 21200.5 among violations requiring a court appearance.
The exact procedures can depend on the court handling the case and the circumstances of the charge.
Can You Get a Bicycle DUI on an Electric Bicycle?
Yes. California law expressly treats qualifying electric bicycles as bicycles for purposes of the state’s bicycle provisions.
Vehicle Code § 312.5 defines an electric bicycle and establishes three classes of electric bicycles. It also provides that a person riding an electric bicycle is subject to Article 4 of Chapter 1 of Division 11, which includes Vehicle Code § 21200.5.
In addition, Vehicle Code § 24016 provides that an electric bicycle is not a motor vehicle for purposes of the statutory framework discussed in that section. The 2026 Court of Appeal decision in Beale relied heavily on these provisions when analyzing the driver’s-license issue in that case.
What Did Beale v. Department of Motor Vehicles Decide?
The 2026 California Court of Appeal decision in Beale v. Department of Motor Vehicles is particularly important when discussing electric bicycle DUI cases.
The case involved a person who was riding an electric bicycle, was suspected of being under the influence of alcohol, and refused a requested chemical test. The DMV subsequently suspended his driver’s license under the administrative suspension provisions of Vehicle Code § 13353.
The Court of Appeal concluded that the statutory scheme did not authorize the DMV to suspend the driver’s license of an electric bicycle rider under § 13353. The court held that an electric bicycle is not a “motor vehicle” for purposes of that license-suspension provision and directed that the suspension be rescinded.
The court also explained that Vehicle Code § 21200’s provisions concerning bicyclists do not incorporate the driver’s-license suspension provisions of § 13353. Section 21200 primarily addresses provisions within specified parts of the Vehicle Code, while § 13353 is located in the driver’s-license division.
What Does the Beale Decision Mean?
The decision does not mean that riding an electric bicycle while under the influence is legal.
Instead, it distinguishes the bicycle DUI offense from the administrative driver’s-license suspension system applicable to qualifying motor-vehicle DUI cases.
In other words:
- A person can still be subject to Vehicle Code § 21200.5 for riding a bicycle under the influence.
- A qualifying electric bicycle remains subject to California’s bicycle laws.
- But the administrative driver’s-license suspension provisions in § 13353 do not automatically apply to an electric bicycle rider.
The precise facts and type of bicycle involved can matter.
Can a Bicycle DUI Suspend Your Driver’s License?
For an adult riding a qualifying electric bicycle, the 2026 Beale decision is important because the Court of Appeal held that § 13353 did not authorize the driver’s-license suspension at issue in that case.
This is different from a conventional motor-vehicle DUI, where California’s administrative driver’s-license suspension laws can apply when statutory requirements are met.
There is also a separate statutory provision concerning certain individuals under 21. Vehicle Code § 21200.5 expressly states that violations are subject to § 13202.5. The Court of Appeal in Beale noted that § 13202.5 provides for suspension of driving privileges for certain alcohol- or controlled-substance-related violations involving individuals under 21.
Because the interaction between the statutes can be technical, driver’s-license consequences should be evaluated based on the person’s age, the exact charge, the type of bicycle, and the circumstances of the case.
Can Police Ask for a Chemical Test After a Bicycle DUI Arrest?
Yes.
Vehicle Code § 21200.5 specifically provides that a person arrested for an alleged violation may request a chemical test of their blood, breath, or urine to determine alcohol or drug content. If the person makes the request, the arresting officer must have the test performed.
The statute references Vehicle Code § 23612 in describing the chemical test.
This provision should not be confused with the separate administrative driver’s-license consequences that can apply to motor-vehicle DUI arrests. In Beale, the Court of Appeal specifically considered the relationship between the bicycle DUI statute, chemical testing, and the DMV’s license-suspension authority.
What Evidence Can Be Used in a Bicycle DUI Case?
A bicycle DUI case may involve several types of evidence.
Law-Enforcement Observations
An officer may document how the cyclist was riding, whether the cyclist appeared to have difficulty maintaining control, and other observations made during the encounter.
Statements
Statements made by the cyclist during the encounter may become part of the evidence, depending on the circumstances.
Chemical-Test Results
Blood, breath, or urine testing may provide evidence concerning alcohol or drug content.
Video Evidence
Body-camera footage, surveillance footage, traffic-camera recordings, or other video may provide information about the cyclist’s conduct.
Witness Testimony
Other cyclists, pedestrians, motorists, or other witnesses may have observed the person’s behavior before or during the incident.
No single category of evidence necessarily determines the outcome of every case. The relevance and weight of the evidence depend on the circumstances.
What Happens if an Impaired Cyclist Causes an Accident?
Vehicle Code § 21200.5 specifically addresses riding a bicycle under the influence. If an accident occurs, however, the incident may involve additional legal issues.
Depending on the facts, those issues could involve:
- Injuries to another person;
- Property damage;
- Alleged reckless conduct;
- Other traffic violations;
- Leaving the scene of an accident; or
- Potential civil claims for injuries or property damage.
The consequences of a bicycle accident therefore cannot necessarily be determined by looking only at § 21200.5.
For example, a cyclist who is accused of riding under the influence and causes a serious collision may face a substantially different legal situation from a cyclist who is stopped without an accident.
Does California Treat Bicycles Like Motor Vehicles?
Not for every purpose.
California law gives bicyclists many of the same rights and responsibilities that apply to drivers of vehicles. Vehicle Code § 21200 states that a person riding a bicycle on a highway has the rights and is subject to provisions applicable to a driver of a vehicle under specified portions of the Vehicle Code, including provisions concerning driving under the influence.
However, that does not mean that every statute applying to a motor-vehicle driver automatically applies to a bicyclist.
The Beale case demonstrates why this distinction matters. The Court of Appeal concluded that § 21200 did not incorporate the driver’s-license suspension provisions of § 13353 because those provisions are located in a different division of the Vehicle Code.
Therefore, it is important to identify the exact statute at issue rather than assuming that bicycle and motor-vehicle DUI laws have identical consequences.
Does Vehicle Code § 21200.5 Apply to Drugs?
Yes.
Vehicle Code § 21200.5 expressly prohibits riding a bicycle while under the influence of any drug, as well as under the combined influence of alcohol and a drug.
The statute therefore covers more than alcohol-related impairment.
The evidence and legal issues in a drug-related bicycle DUI case can differ depending on the substance involved and the evidence concerning impairment.
What Is the Difference Between a Bicycle DUI and a Regular DUI?
Although both offenses involve alleged impaired operation, they are governed by different statutory provisions.
A traditional California DUI generally involves the operation of a vehicle under statutes such as Vehicle Code § 23152. Bicycle DUI is specifically addressed by Vehicle Code § 21200.5.
Some key differences include:
| Issue | Bicycle DUI – § 21200.5 | Traditional Motor-Vehicle DUI |
|---|---|---|
| Statute | Vehicle Code § 21200.5 | Commonly Vehicle Code § 23152 and related provisions |
| Vehicle involved | Bicycle, including qualifying electric bicycle | Motor vehicle or other vehicle covered by applicable DUI law |
| Classification | Misdemeanor | Generally a misdemeanor for common first-offense DUI, subject to circumstances and applicable law |
| BAC threshold in the statute | No .08% threshold stated in § 21200.5 | California DUI statutes contain separate BAC provisions |
| Maximum fine under the bicycle statute | $250 | Different penalties apply |
| Jail under § 21200.5 itself | Not provided | Possible under applicable motor-vehicle DUI statutes |
| Driver’s-license consequences | Different statutory rules apply | DMV administrative suspension laws may apply |
| Chemical testing | Specifically addressed by § 21200.5 | Governed by separate DUI testing provisions |
This comparison is a general overview and does not address every possible charge or circumstance.
