BUI vs. DUI: Understanding their Differences and Similarities

Most people know the term DUI, or driving under the influence refers to operating a vehicle while intoxicated or under the influence of drugs or alcohol. However, the consequences of biking or cycling under the influence (BUI) are not as commonly known.

Biking or cycling may seem harmless, but biking under the influence can have severe penalties, just like getting a DUI on a car or motorbike. Many states, including California, have specific laws against biking under the influence. California’s vehicle code 21200.5 specifies that it is unlawful to ride a bicycle while under the influence of drugs or alcohol.

This article will discuss the key differences and similarities between DUI and BUI. It is essential to understand these distinctions to ensure you are not at risk of getting a fine or even being arrested.

While biking may seem like a more recreational, harmless activity, it is still considered a vehicle in the eyes of the law, and therefore, DUI laws may also apply to cycling under the influence. So, let’s dive into the specifics and uncover the truth about BUI and DUI.

What are BUI and DUI?

Biking Under the Influence (BUI) and Driving Under the Influence (DUI) involve operating vehicles while impaired by alcohol or drugs. While BUI pertains specifically to biking under the influence, DUI applies to driving motor vehicles while intoxicated. Both offenses carry serious consequences and are considered misdemeanors in California.

Biking Under the Influence (BUI)

Biking Under the Influence (BUI) refers to riding a bicycle on public roads, highways, or bikeways while under the influence of alcohol or drugs. Despite the absence of a motor vehicle, California law recognizes that impaired bicyclists can still pose risks to themselves and others. It is unlawful for anyone to propel a bicycle upon a highway while under the influence of alcohol, drugs, or a combination of both.

In California, the legal blood alcohol concentration (BAC) limit for a BUI offense is the same as for DUI offenses, which is 0.08%. This means that if a bicyclist’s BAC is 0.08% or higher, they can be charged with BUI. It is important to note that even if a bicyclist’s BAC is below 0.08%, they can still be cited for other infractions, such as public intoxication if their behavior poses a risk to themselves or others.

Driving Under the Influence (DUI)

Driving Under the Influence (DUI) involves operating a motor vehicle while impaired by alcohol or drugs. Motor vehicles encompass cars, trucks, motorcycles, and any other vehicle powered by an engine. Drunk driving is a serious offense in California with legal and administrative consequences.

The legal BAC limit for a DUI offense in California is also 0.08%. If a driver’s BAC exceeds this limit, they can be charged with DUI. However, it is important to note that even a BAC below 0.08% can still result in a DUI charge if the driver’s ability to operate the vehicle is impaired.

DUI offenses in California are considered misdemeanors but can result in severe penalties. These penalties may include fines, license suspension, mandatory attendance at alcohol or drug education programs, probation, and even jail time, particularly for repeat offenses or cases involving aggravating factors such as accidents or injuries.

It is worth mentioning that public intoxication is a separate offense that pertains to being intoxicated in a public place, such as sidewalks or parks. While it is not specifically related to operating a vehicle, including bicycles, public intoxication can still have legal consequences.

Similarities Between BUI and DUI

Several similarities emerge when comparing BUI (biking under the influence) and DUI (driving under the influence). Both offenses involve impaired judgment and coordination due to the influence of alcohol, specifically an alcoholic beverage or drugs. The effects of alcohol on the central nervous system can compromise reaction times, motor skills, and decision-making abilities, whether one is operating a bicycle or a motor vehicle.

From a Legal Standpoint

BUI and DUI are considered criminal offenses in California. Being charged with either offense can have significant legal implications. Penalties for both BUI and DUI include fines, probation, mandatory alcohol or drug education programs, and even potential jail time. The severity of the penalties may increase for repeat offenses or cases involving injuries or fatalities.

Furthermore, both BUI and DUI can impact driving or biking privileges. While a bicyclist’s driver’s license cannot be suspended, being charged with BUI may still have consequences for individuals with a driver’s license, potentially affecting their future driving privileges.

It is essential to recognize that BUI and DUI are crimes in California, and being charged with either offense can have serious repercussions. These offenses fall under the purview of California Vehicle Code Section 21200.5, which specifically addresses biking under the influence. Individuals charged with a DUI on a bicycle, sometimes called a CUI (cycling under the influence) or a drunk cyclist, can face legal consequences under this vehicle code section.

Differences between Biking Under the Influence and Driving Under the Influence

Vehicle Type

BUI offenses specifically address riding bicycles. While motor vehicles inherently pose greater risks due to their speed and size, it is important to acknowledge that even bicycles, when ridden by impaired individuals, can still endanger themselves and pedestrians.

Speed and Potential for Harm

Motor vehicles can reach high speeds, making them more likely to cause severe harm in the event of an accident. Conversely, bicycles typically operate at lower speeds, reducing the potential for significant harm to others in a collision. However, it is crucial to understand that impaired bicyclists can still pose risks to their safety and the safety of pedestrians, despite lower speeds.

Testing and Evidence

Breathalyzers and Blood Tests

In DUI cases, testing for alcohol impairment commonly involves using breathalyzers or blood tests to determine the driver’s blood alcohol concentration (BAC). However, using breathalyzers may not be as prevalent when testing bicyclists for BUI. Instead, if there is reasonable suspicion, law enforcement officers can request a blood test to assess the presence and level of alcohol or drugs.

Challenges in Testing Bicyclists

Testing bicyclists for impairment poses unique challenges compared to testing motorists. Unlike drivers, bicyclists are not required to carry identification, which makes it more difficult for officers to positively identify an individual and conduct testing. Additionally, establishing probable cause for testing may be more complex, as bicyclists may exhibit different signs of impairment than drivers.

Apprehension and Detention

Traffic Stops vs. Bike Stops

Law enforcement officers typically conduct traffic stops by pulling over motor vehicles when apprehending individuals suspected of DUI. However, the process of apprehension and detention for BUI may differ. In the case of BUI, law enforcement officers can initiate a bike stop by signaling the bicyclist to stop, allowing them to detain the individual for suspected BUI.

Arrest Procedures and Field Sobriety Tests

Arrest procedures and field sobriety tests are standard protocols during DUI stops. However, for BUI, the process may vary. Officers may administer field sobriety tests to assess the impairment levels of bicyclists. If probable cause is established, they can proceed with an arrest and further testing, such as blood tests, to gather additional evidence.
