Bike Laws for Honolulu, HI


Simple answer: Yes. Any bicycle (with wheels over 20″ in diameter) that will be operated on the roadways must be registered with the City & County of Honolulu to ride on O‘ahu (it’s a $15 one-time fee that can really help HPD get your bike back to you in the case it gets stolen). The (one-time) registration fee for Class 1 pedal-assist electric bicycles (under than 750watts / 1 h.p.) is $30. 

TIP: Check out the helpful guide HBL put together on how to register your new/used/second-hand bicycle.

If you are under 16 years of age and biking, yes, you must wear a helmet when biking.

HEAD’s UP: HBL believes that helmets, when correctly fit to a rider’s head, offer potentially life-saving benefits–whether you’re 16 & 1/2 years old, 60 years old, novice or been riding all your life.

Yes. In residential areas (places with just houses all around), you can bike on the sidewalk. HI Law also says you are not allowed to ride any faster than 10MPH; you must yield to all pedestrians, as well as give them a (friendly) heads up with your voice/bell before you pass them.

TIP: Be extra cautious though since drivers & pedestrians are expecting slower-moving walkers there & may not see you if you’re riding quickly.

Sidewalk biking in any Business District like Waikīkī or Downtown is illegal. Basically, if you’re not a residential area, don’t bike on the sidewalk.

Lights! And reflectors. HI Law states that from 30min. after the sun sets till 30min. before the sun rises, your bike must have at least:

  • Front white light
  • Rear red reflector
  • Side reflective material or lighted lamps

TIP: Adding a rear flashing red light and more reflectors to your clothing/bags & bike is a great idea. Slow your speeds down, ride even more attentively, and bike where you are sure to be seen.

Bike Laws for Honolulu, HI

This comprehensive list of regulations was taken from the City & County of Honolulu Department of Transportation Services (DTS) website. It covers everything from where bikes can ride, to sidewalk laws, helmet usage, and dooring. The more frequently used section links are bold.

If there is a disagreement about what the law means, it’s best to use the full legal text.

HRS 291-C refers to state law in effect statewide. Sections 15- refer to Honolulu’s Revised Ordinances, which apply to Honolulu only; each county may have it’s own ordinances which differ from Honolulu’s.

[Since July 10, 2012 the new Vulnerable Users Law is in effect. This law doubles penalties for motorists who kill or seriously injure vulnerable users (cyclists, pedestrians, police officers, road workers, etc.) acting legally. View the full Vulnerable Users law here.]

Riding on roadways and bikeways (§291C-145)

Link to full legal text

When traveling slower than the normal speed of traffic, bicyclists are to ride as close to the right hand curb or on the shoulder of the roadway, as practical. Be careful when passing a stopped vehicle or one going the same direction. There are the allowed exceptions to the “right hand” rule:

  • When preparing for a left turn at an intersection, private road, or driveway;
  • When necessary to avoid hazards that make it unsafe to ride along the right hand curb. This includes situations where the traffic lane is too narrow for a bicycle and a motor vehicle to travel safely side-by-side; or
  • When one-way streets have more than one lane of traffic, the bicyclist may ride near the left hand curb or edge.

On a roadway, bicyclists must ride single file. On bicycle lanes and paths, riding two abreast is permitted when the lane or path is wide enough and when there is no rule or ordinance specifically prohibiting it.

When a roadway has a usable bicycle lane, bicyclists must ride within the lane if they are going slower than the normal speed of traffic moving in the same direction.
Bicyclists are allowed to move out of the lane when:

  • Wishing to pass another vehicle or a pedestrian and they cannot safely do so while staying within the lane;
  • Preparing for a left turn at an intersection, private road, or driveway; or
  • Avoiding debris or other hazardous conditions.
  • Bicyclists are not to leave a bicycle lane unless the movement can be done safely and then only after they have given the appropriate turn signal.

Bicyclists riding in a bicycle lane shall travel in the same direction as the traffic in the adjoining roadway lane. When riding on bicycle paths wide enough for two-way traffic, bicyclists must stay to their right.

The State and City governments have the right to restrict or ban the use of mopeds on bikeways.

The City government, by ordinance, may post signs on bicycle lanes and paths prohibiting motorized bicycles from using them.

Carrying articles (§291C-146)

Link to full legal text

Bicyclists cannot carry a package or article which prevents the driver from using both hands to control and operate the bicycle. One hand must be on the handlebars at all times.
