Idaho Stop Law for Bicycles: Stop Signs, Red Lights and Drivers

informational·how to guide·Published March 29, 2026

What is the Idaho stop law? Can bicyclists roll through stop signs and red lights?

Under Idaho Code 49-720, a bicyclist may roll through a stop sign without a full stop. The rider must slow down, stop if safety requires, and yield to any vehicle in or close to the intersection. At a steady red light, the rider must stop and yield first, then may go with caution. Drivers must still stop at every stop sign.

Where the Idaho bicycle law facts come from

The bicyclist rules come from Idaho Code 49-720. The driver rules come from Idaho Code 49-807, the stop sign and yield sign law. The advice for drivers near bicyclists comes from the Idaho Driver's Handbook of the Idaho Transportation Department (ITD). This guide is current as of 2026. Confirm the rules with the Idaho Transportation Department DMV (itd.idaho.gov/dmv) or your county driver's license office before you drive.

What a bicyclist may do in Idaho, and what the rider must do first

What a bicyclist may do in Idaho, and what the rider must do first
Situation	What the bicyclist must do	What the bicyclist may then do
Stop sign	Slow down. Stop only if safety requires. Yield to vehicles in or close to the intersection.	Turn or go through without stopping, with caution
Steady red light	Stop before the intersection. Yield to all other traffic.	Go through with caution
Right turn on red	Slow to a reasonable speed. Yield if required.	Turn right with caution
Left turn on red onto a one-way road	Stop and yield to other traffic.	Turn left

How the Idaho stop works at a stop sign

Idaho Code 49-720 covers a bicycle, a human-powered vehicle and an electric-assisted bicycle that approach a stop sign. The rider slows down and, if safety requires, stops before the intersection. Then the rider yields to any vehicle in the intersection, or on the other road so close that it is an immediate hazard. After that, the rider may turn or go straight through without stopping. So a bicyclist who slows, yields and rolls on is following Idaho law. Try our free question on what Idaho requires of a bicyclist at a STOP sign.

Does the Idaho stop law apply to e-bikes?

At a stop sign, yes. Idaho Code 49-720 names electric-assisted bicycles next to bicycles and human-powered vehicles, so an e-bike rider may slow, yield and go on the same terms. The red light rule is different: it names only bicycles and human-powered vehicles, and it does not name electric-assisted bicycles. For the order that a bicyclist follows at a steady red light (stop, yield, then go with caution), try our free question on the red light rule for bicyclists.

What drivers must do at a stop sign when a bicyclist is near

The bicyclist law does not change your duty as a driver. Under Idaho Code 49-807, you must stop at the stop line, before the crosswalk, or at the point where you can see cross traffic. After you stop, you yield to any vehicle in the intersection or so close that it is an immediate hazard. A bicyclist does not have to stop fully, so scan the corners of the intersection more than once: a bicyclist can travel 50 to 100 feet in a few seconds. For the order of turns at other junctions, see our guide to Idaho four-way stops and roundabouts.

How to pass a bicyclist safely in Idaho

You can move into the left lane

Move into the left lane to pass. This increases the safety margin for the bicyclist.

You cannot change lanes

Pass with as much space as possible. The Idaho Driver's Handbook gives 3 feet as the minimum passing space, and higher speeds need more. Wait until you can see oncoming traffic, then move partly or fully into the other lane.

Oncoming traffic blocks the other lane

Stay behind the bicyclist, do not follow too closely, and wait for a break in oncoming traffic. The wait is usually brief.

The bicyclist is a child

Slow down and pass with extra caution and distance. Children on bicycles may swerve into your lane without warning.

Other rules for driving near bicyclists in Idaho

Expect bicyclists on any road. The handbook says bicyclists may legally ride on all Idaho roadways and have the same rights as drivers.
Stay alert. Bicyclists have little protection, and most collisions injure the rider.
Check for bicyclists before you open the driver's door, and do not park in a bike lane.
Do not rush a turn or squeeze past a bicyclist to beat traffic or a light.
Use your turn signal so that bicyclists know what you plan to do.

How to turn right when a bicyclist is beside you

1
Slow down and stay behind the rider
Do not assume that you can beat the bicyclist to the turn. Stay behind the bicyclist until the rider passes the point where you will turn. This avoids a right-hook crash. See our free question on turning right near a bicyclist.
2
Signal your turn
Turn on your right signal so that the bicyclist and other drivers know your intent.
3
Look all ways before you go from a stop
If you are stopped, look left, right and to the rear, and check the right first. A bicyclist who rides on the sidewalk or against traffic may come from your right.
4
Yield in a dashed bike lane area
Where a dashed bike lane line shows that your turn path crosses the lane, right-turning drivers must yield to a bike already in that area.

Key takeaways

A bicyclist at an Idaho stop sign must slow down, stop if safety requires, and yield. Then the rider may go on without a full stop.
At a steady red light, a bicyclist must stop and yield first, then may go with caution. The red light rule names bicycles and human-powered vehicles, not e-bikes.
Drivers must still stop at every stop sign, then yield. The handbook says to leave at least 3 feet when you pass a bicyclist, and more at higher speeds.

Idaho stop law for bicycles: common questions

How long has Idaho had the Idaho stop law?

Idaho Code 49-720 was added in 1988. The legislature amended it in 2005 and again in 2019. It is a long-standing Idaho rule, so a driver should expect to meet bicyclists who slow and yield at a stop sign instead of stopping fully.

What should I do if a bicyclist rolls up to a stop sign at the same time as me?

Both of you must yield to any vehicle in the intersection or so close that it is an immediate hazard. You must stop first, but the bicyclist does not have to stop fully. So do not assume that the rider will stop. Wait for a clear gap, and look one last time before you go.

Why is a bicyclist riding in the middle of the lane?

Bicyclists must ride as close to the right edge as safety allows. The exceptions are when they pass, turn left, avoid an obstacle, or when the road is too narrow for a bicycle and a car side by side. On some narrow streets, bicyclists must ride in the center of the lane for safety. Stay back and wait for a safe place to pass.

Do bicyclists in Idaho have to signal turns?

Yes. Under Idaho Code 49-720, a bicyclist must signal a right or left turn during at least the last 100 feet before the turn. The rider does not need to give a hand and arm signal when that hand is needed to control or operate the bicycle.

Can bicyclists ride on the sidewalk in Idaho?

In most Idaho communities, yes. The handbook says bicyclists can legally ride on sidewalks in most communities, but no law requires them to. Young children usually ride on the sidewalk. Be extremely careful when you pull in or out of a driveway.

Can I honk at a bicyclist who is in my way?

No. Never honk when you are close to a bicyclist, because it can startle the rider and cause an unexpected reaction. If you want to be sure that the rider sees you, wave a hand or nod your head, and wait for the rider's reaction.
