Getting a DUI on a bicycle in Arizona is legally possible because ARS 28-101 classifies bicycles as vehicles, and ARS 28-1381 prohibits operating any vehicle while impaired. A bicycle DUI in Maricopa County carries the same criminal penalties as a motor vehicle DUI, including jail time and fines exceeding $2,500. Call Oliverson Law at (480) 582-3637.
Why Arizona Law Treats Bicycles as Vehicles for DUI Purposes
The question of whether you can receive a DUI while riding a bicycle in Arizona comes down to how the state defines “vehicle.” Unlike some states that limit DUI enforcement to motorized vehicles, Arizona uses an expansive statutory definition that sweeps in bicycles, e-bikes, horses, and virtually anything that transports a person on a public roadway.
ARS 28-101(57) defines “vehicle” as a device in, upon, or by which a person or property is or may be transported or drawn upon a highway. A standard pedal bicycle clearly satisfies this definition because it transports a person along a road or bike lane. There is no engine requirement, no registration requirement, and no minimum speed threshold. If the device moves a person on a highway as defined by Arizona law, it qualifies as a vehicle.
ARS 28-1381 then applies the DUI prohibition to any person who drives or is in actual physical control of a vehicle while under the influence of intoxicating liquor, any drug, a vapor releasing substance containing a toxic substance, or any combination of those substances. Because “vehicle” includes bicycles, the DUI statute reaches cyclists who ride impaired on public roads, designated bike lanes, shared-use paths that cross public roadways, and residential streets throughout Arizona.
This statutory framework means that a cyclist stopped by a Tempe police officer on Mill Avenue, a Scottsdale officer near Old Town, or a Phoenix officer along the canal paths that intersect public roads faces the identical DUI charging process as a motorist. The officer can request field sobriety tests, administer a portable breath test, and invoke the implied consent law under ARS 28-1321 for a blood or breath sample. Refusing the chemical test triggers the same administrative license consequences through the ADOT Executive Hearing Office, though the practical impact differs for bicycle-only riders as discussed below.
Arizona is not unique in this approach, but it is among the strictest. States like California and Colorado have carved out exceptions that reduce bicycle DUI to a lesser offense or exclude bicycles from their DUI statutes entirely. Arizona has not made that distinction, and no pending legislation would change the current framework. A bicycle DUI arrest in Maricopa County proceeds through the same court system and under the same statutes as any other DUI case.
Criminal Penalties for a Bicycle DUI Conviction
Because Arizona treats bicycle DUI identically to motor vehicle DUI at the statutory level, the criminal penalties mirror those for any first-offense DUI under ARS 28-1381. Courts do not impose a reduced penalty simply because the defendant was on a bicycle rather than behind the wheel of a car.
Jail time for a first-offense standard DUI carries a minimum of one day and a maximum of six months in a city or county jail. Arizona’s mandatory sentencing structure under ARS 28-1381(I) requires judges to impose at least 24 consecutive hours of incarceration for a first offense, with 10 days minimum for a second offense within 84 months. Bicycle DUI defendants face these same minimums regardless of the vehicle type involved.
Fines and surcharges for a first-offense misdemeanor DUI routinely exceed $2,500 once mandatory assessments, surcharges, and the prison construction fund contribution are calculated. The base fine may appear modest, but Arizona adds an 84% surcharge, a $500 DUI abatement fee, and additional assessments that push the total well beyond the statutory minimum. A second bicycle DUI within 84 months carries even steeper mandatory fines.
Alcohol screening and treatment are mandatory after any Arizona DUI conviction. The court orders a screening assessment through an approved provider, which determines whether you need education classes, outpatient counseling, or intensive treatment. Costs range from $100 for the screening to $500 or more for the required program. Failure to complete treatment can result in a warrant and additional penalties.
Probation typically accompanies a first-offense DUI sentence and can last up to five years for a misdemeanor conviction. Probation conditions may include random testing, community service hours, attendance at a Mothers Against Drunk Driving victim impact panel, and compliance with all screening and treatment recommendations. Violating any probation condition triggers a revocation hearing and potential jail time.
| Penalty Component | First Offense (Bicycle DUI) | Second Offense within 84 Months |
|---|---|---|
| Minimum Jail | 1 day (24 consecutive hours) | 30 days (minimum) |
| Maximum Jail | 6 months | 6 months |
| Fines & Surcharges | $2,500+ | $3,500+ |
| Alcohol Screening | Mandatory | Mandatory |
| Probation | Up to 5 years | Up to 5 years |
| Community Service | Possible | 30 hours minimum |
| Criminal Record | Class 1 misdemeanor | Class 1 misdemeanor |
How Bicycle DUI Differs from Motor Vehicle DUI
While the criminal penalties are identical, bicycle DUI produces several practical differences in how the conviction affects your driving privileges and ongoing obligations. These distinctions matter for anyone weighing the real-world consequences of a bicycle DUI arrest versus a motor vehicle DUI.
No license points are assessed. Arizona’s Motor Vehicle Division assigns points to your driving record when you are convicted of a traffic violation involving a motor vehicle. Because a bicycle is not a motor vehicle, ADOT does not add points to your driving record for a bicycle DUI conviction. Your driving record remains unaffected by the conviction itself, though the criminal record still exists in court databases and background check systems.
No ignition interlock requirement. Arizona law mandates ignition interlock device installation for most motor vehicle DUI convictions under ARS 28-3319. The interlock device prevents a vehicle from starting until the driver provides a breath sample below a set threshold. Because the device is designed for motor vehicles and the conviction did not involve one, courts do not order ignition interlock installation for a bicycle-only DUI. This saves convicted bicycle DUI defendants approximately $1,500 or more in installation, calibration, and monthly monitoring fees over a typical 12-month interlock period.
No motor vehicle insurance consequences directly from the conviction. Auto insurance companies track motor vehicle violations through your MVD driving record. Because a bicycle DUI does not appear on your MVD record and does not trigger SR-22 high-risk insurance filing requirements, your auto insurance premiums may not increase as a direct result of the conviction. However, if the insurer discovers the DUI conviction through a background check or court records during underwriting, they may adjust rates at renewal.
The criminal record impact is identical. A bicycle DUI conviction creates a class 1 misdemeanor on your criminal record under Arizona law. It appears in court records, on background checks run by employers, and in any future criminal proceedings. If you are arrested for a second DUI of any kind within 84 months, the bicycle DUI counts as a prior offense that triggers enhanced mandatory penalties. A third DUI within 84 months, regardless of whether the prior offenses involved bicycles or motor vehicles, triggers an Aggravated DUI felony charge under ARS 28-1383.

E-Bikes, Electric Scooters, and Other Non-Motor Vehicles
The same vehicle definition that brings traditional pedal bicycles under Arizona’s DUI statute also covers electric bicycles, electric scooters, and other personal transportation devices that have become common across Maricopa County’s urban areas.
Electric bicycles (e-bikes) are explicitly defined in ARS 28-101 across three classes based on motor wattage and activation method. Class 1 e-bikes provide pedal-assist up to 20 mph. Class 2 e-bikes include a throttle that propels the bike without pedaling, also capped at 20 mph. Class 3 e-bikes offer pedal-assist up to 28 mph. All three classes qualify as vehicles under the DUI statute. The electric motor does not change the analysis because the base definition already covers unpowered bicycles. Riding an e-bike while impaired on the Tempe Town Lake path where it crosses public roadways, along Scottsdale Road, or through downtown Mesa bike lanes subjects the rider to the same ARS 28-1381 enforcement as any other vehicle operator.
Electric scooters available through rental programs in Tempe near Arizona State University, along the Scottsdale entertainment district, and in downtown Phoenix also fall within the vehicle definition. These stand-up scooters transport a person along public roads and sidewalks, satisfying the ARS 28-101 definition. Multiple DUI arrests involving rental e-scooters have occurred in the Mill Avenue district in Tempe, particularly during evening hours when bar traffic and scooter availability overlap. Riders often assume the scooter’s small size or low speed exempts them from DUI enforcement, but Arizona law makes no such distinction.
Other devices that meet the vehicle definition include motorized skateboards, Segways, golf carts operated on public roads, and even horses. Arizona case law has addressed DUI charges involving horseback riders, and courts have found that a horse meets the vehicle definition when ridden on a public highway. The unifying principle is whether the device or animal transports a person on a roadway, not whether it has an engine or requires a license to operate.
Defense Strategies Specific to Bicycle DUI Cases
Bicycle DUI cases present defense opportunities that differ from standard motor vehicle DUI cases. Several aspects of a bicycle arrest are inherently weaker for the prosecution, and an experienced DUI defense attorney can exploit these vulnerabilities through pretrial motions and at trial.
Challenge the Initial Stop and Probable Cause
Officers need reasonable suspicion to stop a cyclist, just as they do for a motorist. Unlike motor vehicles, bicycles naturally wobble, swerve, and travel at uneven speeds. Riding behavior that might indicate impairment in a car, such as weaving within a lane or varying speed, can be entirely normal on a bicycle. Defense counsel can argue that the officer lacked reasonable suspicion for the stop because the observed cycling behavior fell within the range of normal, sober bicycle operation.
Question Field Sobriety Test Reliability
Standardized field sobriety tests were developed by the National Highway Traffic Safety Administration for motor vehicle drivers. The walk-and-turn test, one-leg stand, and horizontal gaze nystagmus test were validated for people who had been driving cars, not cycling. Physical exertion from pedaling, elevated heart rate, leg fatigue, and the balance adjustments required for cycling can all produce false indicators of impairment on these tests. An experienced attorney can challenge the reliability of FST results administered immediately after a cyclist dismounted.
Dispute the Location of the Arrest
ARS 28-1381 applies to the operation of a vehicle, and ARS 28-101 defines “highway” as the entire width between the boundary lines of every way publicly maintained when any part thereof is open to the use of the public for purposes of vehicular travel. If the bicycle was being ridden on a private path, a canal towpath not maintained as a public roadway, or within a private community, the DUI statute may not apply. Establishing that the arrest location was not a public highway can serve as a complete defense.
Challenge Chemical Test Procedures
Blood draw and breath testing procedures must comply with Arizona’s implied consent framework and the requirements established in State v. Butler, 232 Ariz. 84 (2013) and State v. Valenzuela, 239 Ariz. 299 (2016). If the officer obtained a blood sample without a valid warrant or proper consent, the results may be suppressed. Independent blood retesting through a private laboratory can also reveal discrepancies in the state’s reported BAC level. These challenges apply equally to bicycle and motor vehicle DUI cases.

Frequently Asked Questions
Arizona Revised Statutes Section 28-101 defines a vehicle as any device in, upon, or by which any person or property is or may be transported or drawn upon a highway. Bicycles meet this definition because they transport a person on a highway or roadway. ARS 28-1381 applies to any person operating a vehicle while impaired, which includes bicycles. Arizona courts have consistently upheld bicycle DUI charges under this statutory framework without requiring a motor or engine.
A bicycle DUI conviction under ARS 28-1381 carries the same criminal penalties as a motor vehicle DUI. For a first offense, that means a minimum of one day in jail up to six months, fines and surcharges exceeding $2,500, mandatory alcohol screening and treatment, and a DUI conviction on your criminal record. However, bicycle DUI convictions do not add points to your motor vehicle driving record because no motor vehicle was involved, and ignition interlock requirements do not apply to bicycles.
Yes. Electric bicycles and electric scooters are vehicles under ARS 28-101 and are subject to DUI enforcement under ARS 28-1381. Arizona defines e-bikes in three classes under ARS 28-101, all of which qualify as vehicles for DUI purposes. Electric scooters available through rental programs in Tempe, Scottsdale, and downtown Phoenix also fall under the vehicle definition. Operating any of these devices while impaired by alcohol or drugs carries the same DUI charge as driving a car.
Several defenses apply specifically to bicycle DUI cases. Challenging whether the bicycle was operated on a highway or roadway as defined by ARS 28-101 can be effective if the arrest occurred on a private path or property. The absence of erratic driving patterns weakens the probable cause for the stop itself. Field sobriety tests designed for motor vehicle stops may produce unreliable results when administered to someone who was cycling. Additionally, challenging the accuracy of portable breath testing devices used at the scene and requesting independent blood retesting can undermine the chemical evidence.
A bicycle DUI conviction does not result in driver license points because no motor vehicle was involved in the offense. ADOT Motor Vehicle Division does not assess points against your driving record for a bicycle DUI. However, the criminal DUI conviction itself still appears on background checks and court records. If you hold a commercial driver license, any DUI conviction regardless of vehicle type can trigger CDL-specific consequences under federal regulations. The court may also impose alcohol screening and treatment requirements that must be completed before any separate license-related matters are resolved.
