Can you get a DUI on a bicycle in California?

Yes, you can get a DUI on a bicycle in California, but it is not the DUI most people picture. Riding a bike while drunk or high is its own separate offense called cycling under the influence, and the maximum penalty is a $250 fine. It does not carry jail time, it does not put points on your driving record, and for most adult riders it does not touch your driver's license at all.

That said, the answer changes the moment a motor gets involved. An e-bike is still treated as a bicycle, but a moped or a motorized bicycle is a motor vehicle, and riding one while impaired is a full DUI with everything that comes with it. Here is how California actually handles it.

​

Can you get a DUI on a bicycle in California?

You can be cited and arrested for riding a bicycle under the influence, but you are charged under a bicycle-specific law, not the standard DUI statute. Under California Vehicle Code § 21200.5, it is unlawful to ride a bicycle on a public road while under the influence of alcohol, drugs, or both.

The key word is bicycle. California's regular DUI law applies to driving a vehicle, and a bicycle is not a vehicle under the Vehicle Code. So the state wrote a separate rule for cyclists. The offense exists, the police can arrest you for it, but it sits in a completely different category from a car DUI.

One more detail that surprises people: the law only applies on a public road. Cycling under the influence on private property, like a parking lot or a private driveway, falls outside the statute.

​

What is a bicycle DUI called in California?

A bicycle DUI in California is called cycling under the influence, often shortened to CUI. Some people call it biking under the influence, or BUI. Whatever you call it, the charge comes from Vehicle Code § 21200.5, and it is a different animal from the DUI charge a driver faces.

The statute opens with the phrase "notwithstanding Section 21200," which is the law's way of saying this rule stands apart from the general rules of the road for cyclists. Lawmakers carved out a single, narrow offense for impaired cycling and capped what it can cost you.

​

How cycling under the influence differs from a regular DUI

The difference comes down to money, your license, and your record. A standard DUI under California Vehicle Code § 23152 can mean jail, thousands of dollars in fines and fees, a license suspension, mandatory DUI school, and a conviction that follows you for years. Cycling under the influence carries almost none of that.

Here is the practical comparison for an adult rider:

• The fine. A cycling under the influence conviction is capped at $250. A car DUI runs into the thousands once fines, penalty assessments, and fees are added up.
• Jail. Cycling under the influence has no jail penalty written into the statute. A first car DUI can carry up to six months.
• Your driver's license. A cycling under the influence conviction does not suspend an adult's driver's license and does not add points to your driving record. A car DUI does both.
• The legal standard. A car DUI uses the 0.08 percent blood alcohol limit. Cycling under the influence asks whether you were actually "under the influence," meaning your ability to ride safely was impaired. There is no fixed bicycle blood alcohol number.

In short, the state treats a drunk cyclist as a far smaller risk than a drunk driver, and the penalty reflects that.

​

What are the penalties for cycling under the influence?

The penalty for a cycling under the influence conviction is a fine of up to $250, and that is the whole of it for most adult riders. No jail. No probation requirement in the statute. No driver's license suspension.

Two things still matter, though. First, if you are arrested, you have the right to request a chemical test of your blood, breath, or urine to measure what was actually in your system, and the officer has to make that test happen if you ask. Second, the small fine does not make an arrest harmless. You can still be handcuffed, booked, and held until you are sober, and the arrest itself can be a stressful event.

​

Does a bicycle DUI affect your driver's license or insurance?

For an adult, a cycling under the influence conviction does not suspend your driver's license, add DMV points, or raise your car insurance, because the offense is not committed in a motor vehicle. It lives outside the system that tracks driving violations.

The big exception is age. Under California Vehicle Code § 13202.5, a rider who is under 21 and convicted of cycling under the influence faces a one-year suspension of their driving privilege. If the rider does not have a license yet, the DMV delays issuing one for a year. So for a teenager or a college student, a $250 bike citation can quietly become a year without a driver's license. That consequence catches families off guard more than any other part of this law.

​

What about e-bikes, mopeds, and motorized bicycles?

This is where the answer splits, and it depends entirely on what you were riding, not what you call it.

Electric bicycles

A true electric bicycle is treated as a bicycle. California Vehicle Code § 312.5 defines three classes of e-bikes, all with working pedals and a motor of 750 watts or less that stops assisting at either 20 or 28 miles per hour. Because the law classifies these as bicycles, riding one while impaired falls under cycling under the influence, with the same $250 cap. If you want the full picture on how the state regulates these, see our guide to San Diego e-bike laws and regulations.

Mopeds and motorized bicycles

A moped or motorized bicycle is a different category. California Vehicle Code § 406 defines these as devices with a motor under 4 gross brake horsepower that top out at 30 miles per hour. They are motor vehicles. They require a license and a special plate, and riding one while impaired is a standard DUI under Vehicle Code § 23152, not a cycling under the influence citation. That means jail exposure, real fines, and a license suspension are all back on the table.

The takeaway is simple. Pedals and a small motor that quits at e-bike speeds keep you in bicycle territory. A throttle-driven machine that behaves like a small motorcycle pushes you into motor-vehicle DUI law. If you are not sure which one you own, the classification, not the sticker on the frame, is what decides the charge.

​

What defenses exist for a cycling under the influence charge?

The most common defenses challenge whether the state can actually prove the two things the statute requires: that you were "under the influence," and that you were riding on a public road. Because there is no fixed blood alcohol limit for bicycles, the prosecution has to show your ability to ride was genuinely impaired, which is harder to prove than a 0.08 reading. The chemical test you can request after an arrest sometimes helps rather than hurts.

A cycling under the influence charge is a criminal matter, and defending one is the job of a criminal defense attorney. Hulburt Law Firm is a personal injury firm, so this is not the kind of case we take. We mention the defenses only so you understand the charge is not automatic, and a person facing one should talk to a criminal defense lawyer.

​

In what states can you get a DUI on a bicycle?

It varies a lot by state, which is why this question shows up so often. States fall into roughly three groups. Some, like California, have a separate, lighter law just for impaired cycling. Others treat a bicycle as a vehicle for DUI purposes, meaning a drunk cyclist faces the same full DUI charge as a drunk driver. A third group has no clear law on the books for cycling under the influence at all.

Because the rules differ so widely, an answer for one state tells you nothing reliable about another. This article covers California. If you were riding in another state, check that state's specific law.

​

What if you were injured in a bicycle crash?

If a driver hit you while you were cycling, you may have an injury claim even if you had been drinking. California uses a rule called comparative negligence, which means fault can be split between you and the driver. If the driver was 80 percent responsible for the crash and you were 20 percent, you can still recover, with your compensation reduced by your share of the fault. Having had a drink does not erase a careless driver's responsibility. You can read more in our explainer on comparative negligence in San Diego bicycle crash cases.

That distinction matters because the two issues are separate. A cycling under the influence citation is between you and the state. An injury claim is between you and whoever caused the crash. A skilled San Diego bicycle accident attorney can look at the crash, the available insurance coverage, and the fault picture to tell you whether you have a claim worth pursuing.
