Is Vaping or Smoking While Driving Illegal in Hawaii?

If you’re a driver in Hawaii, whether a resident enjoying the island lifestyle or a visitor cruising the scenic highways, you’ve likely wondered about the specific rules of the road regarding smoking and vaping. Can you use your vape pen during your commute in Honolulu? Is it legal to light up a cigarette on the Road to Hana? This guide provides a comprehensive breakdown of Hawaii’s laws on vaping and smoking behind the wheel.

The Direct Answer: No Explicit Ban on Tobacco/Nicotine Vaping for Adults Driving Alone, But…

Let’s start with the most common question: is it illegal for an adult to vape a nicotine product or smoke a traditional cigarette while driving in Hawaii? As of 2025, there is no state statute that specifically makes this activity a traffic violation by itself when you are driving alone or with other adults. Hawaii’s laws governing smoking and the use of electronic smoking devices (ESDs) primarily focus on indoor public places, workplaces, and sales to minors. Private motor vehicles are generally not included in these statewide public use bans unless a minor is present.

However, this is where the nuance begins. The absence of a specific prohibition does not grant a driver immunity from legal consequences if their smoking or vaping leads to unsafe driving behaviors. The key legal frameworks that can come into play are distracted driving laws and, in more serious cases, reckless driving statutes.

When Smoking or Vaping Can Lead to Legal Trouble

Hawaii takes distracted driving very seriously. While the state’s most well-known distracted driving law, Hawaii Revised Statutes (HRS) § 291C-137, primarily targets the use of hand-held mobile electronic devices, the state also has a broader inattentive driving law (HRS § 291C-1213, though some sources cite older statute numbers, the principle remains). This law prohibits operating a vehicle without giving full attention to the task of driving. Any activity that diverts a driver’s attention can be cited under these general provisions.

Smoking or vaping can easily fall into the main categories of distraction:

Manual Distraction: Taking one or both hands off the wheel to find a vape device, search for a lighter, light a cigarette, handle an ashtray, or adjust device settings.
Visual Distraction: Taking your eyes off the road to perform any of the above actions, or if your vision is temporarily obscured by a thick cloud of vapor or smoke.
Cognitive Distraction: Your mental focus is on the act of smoking or vaping rather than on the road and surrounding traffic.

If a law enforcement officer observes you driving erratically (e.g., swerving, failing to maintain a consistent speed) and determines that your smoking or vaping is the cause, you could be cited for inattentive or careless driving. Penalties for distracted driving in Hawaii can be significant, with fines typically starting around $250-$300 for a first offense and increasing for subsequent violations, especially if they occur in school or construction zones. More serious instances could lead to reckless driving charges, which carry potential jail time and license suspension.

The Absolute Prohibition: Vaping or Smoking with Minors in the Car

While adults driving alone or with other adults have some leeway, the rules change completely when a minor is present. Hawaii has a statewide law that makes it illegal to use any tobacco or electronic smoking device (vape) in a motor vehicle when a person under the age of 18 is present. This law is a critical component of the state’s efforts to protect children from the concentrated exposure to secondhand smoke and aerosol in the confined space of a vehicle.

The law defines “smoking” broadly to include exhaling, burning, or carrying any lighted or heated tobacco product or electronic smoking device¹. This ensures that both traditional cigarettes and all forms of vaping are covered. Violation of this provision is subject to county-level fines, which typically range from $100 for a first offense up to $500 for a third offense within one year.

It’s important to note that some older county-level ordinances had different age limits (e.g., Kauai County’s ban applied to minors under 13), but the broader state law and subsequent county alignments (like Honolulu County’s ban for under 18s) have created a de facto statewide standard of protecting all minors under 18.

The Other Absolute Prohibition: Vaping or Smoking Cannabis While Driving

The legal landscape is also starkly different when the substance being vaped or smoked is cannabis. While Hawaii has a medical cannabis program and has decriminalized small amounts of recreational marijuana, it is strictly illegal to smoke or vape marijuana while driving, or as a passenger in an operating vehicle. This falls under the state’s laws against Driving Under the Influence of an Intoxicant (OVUII). Hawaii enforces zero-tolerance for impaired driving, and any consumption of cannabis in a vehicle can lead to serious OVUII charges, including arrest, license revocation, substantial fines, and potential jail time.

Vaping/Smoking Tobacco (with Minor <18 Present)	❌ No	Explicitly prohibited under state law (HRS Chapter 328J).	Fines from $100 (first offense) up to $500 (third offense).

Conclusion:

In conclusion, while Hawaii law does not explicitly ban the act of an adult vaping a nicotine product or smoking a cigarette while driving alone or with other adults, it is far from a risk-free activity.

The most responsible and legally sound advice for all drivers in Hawaii is to keep your full attention on the road. The state’s focus on road safety and public health sends a clear message. As laws and public perceptions continue to evolve, the safest bet is to wait until you have reached your destination or have pulled over to a safe, legal location to smoke or vape. Prioritizing safety not only protects you, your passengers (keiki), and others on the road but also ensures you stay on the right side of the law in the Aloha State.
