Indiana Bicycle Laws Staff Profile Picture
Written By:

Indiana continues to provide safer roads for bicyclists of all ages. Featuring four U.S. Bike Routes, Indiana offers a total of 730 miles of bike lanes, trails, and low-traffic roads suitable for long-distance, experienced, and touring cyclists. 

The state’s U.S. Bike Routes are nestled between scenic roads that connect cyclists with urban cycle tracks. These routes include USBR 35 (381 miles north-south route from Lake Michigan to the Ohio River), USBR 36 (58.7 miles east-west route along Lake Michigan), USBR 50 (160 miles east-west route across central Indiana), and USBR 235 (120 miles between Seymour and Indianapolis). 

Despite having many bike trails throughout the state, bicycle crashes still happen. Cyclists involved in bike accidents may suffer from mild and serious injuries, including whiplash, concussions, road rash, traumatic brain injuries, and even death.

To improve road safety and protect cyclists against accidents, Indiana has implemented laws restricting unsafe riding practices. These measures appear to have paid off, as bike accidents in Indiana decreased by 26% in 2020. From 927 bicycle-related accidents reported in 2016, the number has dropped to 684 over four years.

This article focuses on Indiana laws that apply to cyclists. It equips them with the knowledge necessary to prevent crashes and the legal repercussions associated with violating the rules for operating bicycles. The information that follows also provides guidelines on recovering damages should an accident happen to a cyclist.

Indiana Bicycle Roadway Laws

When riding on public roads in Indiana, cyclists must adhere to the state's roadway laws. These include rules that govern the behavior and actions of cyclists so they do not cause danger to themselves and other road users. The table below lists a variety of traffic situations that Indiana regulates to keep both cyclists and motorists safe. 

Bicyclists riding side-by-side

Bicyclists are not allowed to ride side by side with more than two riders except on dedicated bike paths or sections of the road specifically designated for bicycle use.

Bicyclists at stop signs and traffic devices signaling red

Bicyclists must stop at stop signs and red traffic signals. However, if they have stopped at a red light and waited for two minutes or 120 seconds without the light changing, they may proceed through the intersection after ensuring it is safe to do so.

Bicyclists turning and stopping

Bicyclists must use hand signals to indicate turns and stops. For a left turn, the left arm must be extended horizontally. For a right turn, the right arm must be extended horizontally or the left arm bent upward at a right angle. To signal a stop, bicyclists must extend their left arm downward with the palm facing rearward.

Bicyclists overtaking cars

Bicyclists traveling on roadways should exercise caution when overtaking a stationary or moving vehicle in the same direction.

Cars overtaking bicyclists

Motor vehicle drivers must give bicyclists at least three feet of clearance when passing.

Indiana Bike Paths Law

According to the Indiana Department of Natural Resources, cyclists in Indiana have various opportunities for biking within state parks and reservoirs to encourage outdoor recreation and foster a bike-friendly environment within local communities.

Regular bicycle riders are permitted to ride on paved surfaces and designated trails within these park areas. Cyclists using mountain bikes can explore specific state parks in Indiana with mountain bike trails, such as:

  • Fort Harrison State Park

  • Harmonie State Park

  • Salamonie Lake

  • Versailles State Park

  • Potato Creek State Park

  • Brown County State Park

  • O'Bannon Woods State Park

In addition to state park options, the DNR has compiled a list of cities in Indiana with bicycle-friendly roads. These cities include Allen, La Porte, Elkhart, Wabash, Hamilton, and Kosciusko.

Indiana Bicycle Helmet Law

Wearing a helmet while biking is not mandated in Indiana. Nonetheless, the Indiana Department of Health advises cyclists, both old and young, to wear helmets as a precaution against severe injuries or death in the event of an accident involving motor vehicles.

In addition, the Indiana Department of Homeland Security has issued a helmet safety guide that encourages adults and children to wear helmets regardless of their cycling location.

The guide offers the following safety tips:

  1. Remember to wear a helmet when riding a bicycle.

  2. Make sure the helmet fits the head properly.

  3. Keep the helmet secure, maintaining a level position and avoiding any rocking motion forward, backward, or side to side.

  4. Buckle the helmet straps securely but not excessively tight.

  5. Replace the helmet if it has been involved in a crash or if the foam has cracked.

Indiana Bicycle Operations Law

Indiana Code 9-21-11-3 establishes the regulations for operating bicycles to ensure riders’ safety. Below are some of the practices that cyclists must observe under the law: 

  • Use the bicycle's permanent and regular seat when riding to ensure stability and control.

  • Carry only the number of passengers that the bicycle is designed or equipped to accommodate.

  • Restrict passengers from riding on anything other than a securely attached and standard seat on the bicycle.

  • Refrain from holding onto or clinging to motor vehicles while riding.

  • Avoid carrying or transporting items that hinder a rider’s ability to maintain a secure grip on the handlebars. Removing this type of distraction will give riders optimal control of their bicycles, allowing them to maneuver safely.  

Indiana Bicycle Equipment Law

Indiana laws on bicycle equipment include specific requirements to ensure the safety of cyclists. The following table lists those requirements:



Lamps and reflectors

When operating a bicycle on a highway between half an hour after sunset and half an hour before sunrise, the bicycle must be equipped with the following:

(1) A front lamp that exhibits a white light visible from a distance of at least 500 feet in front of the bicycle

(2) A rear lamp that exhibits a red light visible from a distance of 500 feet behind the bicycle or a red reflector visible from a distance of 500 feet behind the bicycle

Sirens or whistles

Equipping or operating a bicycle with a siren or whistle is prohibited.


A bicycle must have a brake system that allows the braked wheels to skid on level, dry, and clean pavement. This ensures that the person operating the bicycle can effectively stop the bicycle when necessary.

Indiana Is an At-Fault State for Bike Accidents

Indiana operates under the at-fault law, requiring cyclists to prove the other party's negligence in a bicycle collision when they seek compensation for their losses and injuries.

To support their claims, bicycle accident plaintiffs must obtain essential evidence, such as eyewitness testimonies, injury photos, and accident footage, against the defendants. Evidence must clearly depict the incident to strengthen victims’ cases within Indiana's legal framework.

How Much Can Someone Sue for a Bicycle Accident in Indiana?

The amount of compensation plaintiffs can obtain for bicycle accidents in Indiana is determined by the extent of their losses or injuries. For instance, bicycle accident victims in Indiana may pursue claims for their economic losses, which include lost income, property repair expenses, and medical costs. They can also file claims for non-economic or non-monetary damages, such as emotional distress and pain and suffering.

Additionally, Indiana adheres to the comparative fault law, meaning if plaintiffs are found to be partially at fault for the accident, their claims would be reduced by their percentage of fault. However, if they are more than 50% at fault for the bicycle accident, it prevents them from recovering any compensation for their losses.

What Is Indiana’s Statute of Limitations for Bicycle Accidents?

Bicycle accident plaintiffs in Indiana have a two-year window from the date of the accident to file their cases and pursue claims. Complying with the state's statute of limitations for bike accidents prevents the dismissal of their claims.

However, the statute of limitations can be extended under specific circumstances:

  1. If the defendant resides out of state without an in-state agent, the statute of limitations will be postponed.

  2. If the plaintiff, due to being a minor or declared incompetent, is unable to pursue legal action, the statute of limitations will be paused or postponed until he regains legal capacity.

  3. In cases where the defendant fraudulently conceals his wrongdoing, the statute of limitations may be extended until the wrongdoing is discovered or could reasonably have been discovered.
