The baseline in state vehicle codes: a person riding a bike has the rights and duties of the driver of a vehicle. You ride with traffic, obey signals and signs, signal your turns and use lights at night. In return, drivers must treat you as traffic, and most states set a minimum passing distance.
Last checked: October 19, 2026. This is a summary, not legal advice. Traffic laws vary by state and city and change often, so check your state’s vehicle code before you rely on any detail.
Same rights, same duties
State vehicle codes say it almost word for word. Oregon: a person riding a bicycle on a public way “has the same rights and duties as the driver of any other vehicle”, except for rules that by their nature cannot apply to a bike (ORS 814.400). Washington uses nearly the same language (RCW 46.61.755). In practice that means:
- Ride with traffic, on the right side of the road, never against it.
- Obey traffic control devices: stop signs, red lights, one-way streets, unless your state has a stop-as-yield law (below).
- Signal turns by hand when it is safe to take a hand off the bars. Idaho, for instance, asks for a signal during the last 100 feet (30 m) before a turn, but not if you need the hand to control the bike.
- Yield like a driver at intersections and to pedestrians in crosswalks.
“As far right as practicable”
Most states tell slower cyclists to ride as close to the right edge as practicable. “Practicable” means what is safe and reasonable, not the gutter. California’s Vehicle Code § 21202 lists the exceptions, and Florida’s § 316.2065 is very similar. You may leave the right edge:
| Situation | Why you may move left |
|---|---|
| Passing another bike or vehicle | Same as any driver |
| Preparing for a left turn | At an intersection or into a driveway |
| Avoiding hazards | Parked cars, debris, potholes, pedestrians, animals |
| Substandard-width lane | The lane is too narrow for a bike and a car to travel safely side by side, so you may take the lane |
| Approaching a place where a right turn is allowed | To avoid being in the path of right-turning traffic (California) |
| One-way road with two or more lanes | You may ride near the left edge instead |
Florida adds that when a bike lane exists and you are slower than traffic, you must use it, with similar exceptions. On riding side by side, Florida allows two abreast within a single lane as long as you do not impede traffic, and single file in a bike lane too narrow for two.
Safe passing laws by state
Safe passing laws tell drivers how much room to leave when they overtake you. Wisconsin passed the first one in 1973. This table summarizes each state’s statute as compiled by the National Conference of State Legislatures (NCSL) in its chart updated September 5, 2023. A few legislatures have revisited these laws since, so confirm the current text in your state code.
| State | Minimum passing distance | Lane change or other rules |
|---|---|---|
| Alabama | 3 ft, on roads with a bike lane or with a limit of 45 mph or less and no double yellow line | Applies when the cyclist is within 2 ft of the right shoulder |
| Alaska | No specific law | — |
| Arizona | 3 ft | Until safely past |
| Arkansas | 3 ft | — |
| California | 3 ft | Must change lanes if another lane in the same direction is available and practicable |
| Colorado | 3 ft, including mirrors | — |
| Connecticut | 3 ft | — |
| Delaware | 3 ft, with reduced speed, in lanes wide enough to share | Must move fully into the next lane if the lane is too narrow to share |
| District of Columbia | 3 ft | — |
| Florida | 3 ft | May briefly cross the center line to pass |

| Nebraska | 3 ft | — |
| Nevada | 3 ft | Move to the left lane on multilane roads; may use a no-passing zone when safe |
| New Hampshire | 3 ft at 30 mph or less, plus 1 ft for every 10 mph above 30 | — |
| New Jersey | 4 ft | Change to a non-adjacent lane when possible; if you cannot give 4 ft, slow to 25 mph; $100 fine, $500 and 2 points if someone is injured |
| New Mexico | No specific law | — |
| New York | Safe distance (no number in feet) | — |
| North Carolina | 2 ft | May pass in a no-passing zone with 4 ft of space or a full lane change |
| North Dakota | 3 ft | — |
| Ohio | 3 ft | — |
| Oklahoma | 3 ft | Move to the left lane on multilane roads; may cross the center line when clear |
| Oregon | Enough distance to avoid contact if the cyclist fell into your lane | — |
| Pennsylvania | 4 ft | At a careful, reduced speed |
| Rhode Island | Enough distance to avoid contact if the cyclist fell into your lane | — |
| South Carolina | Safe operating distance (no number in feet) | — |
| South Dakota | 3 ft at 35 mph or less; 6 ft above 35 mph | May partially cross the center line when safe |
| Tennessee | 3 ft | — |
| Texas | No specific statewide law | — |
| Utah | 3 ft | — |
| Vermont | Increased clearance (no number in feet) | — |
| Virginia | 3 ft | Must change lanes if the lane is too narrow to pass with that space |
| Washington | 3 ft where practicable on single-lane roads | Move fully into the left lane on multilane roads; into the oncoming lane when safe if there is not enough room |
| West Virginia | 3 ft | At a careful, reduced speed |
| Wisconsin | 3 ft | — |
| Wyoming | 3 ft, including mirrors, when space allows | — |
Three feet is 0.9 m, 4 feet is 1.2 m and 6 feet is 1.8 m. Where a state has no number, the general rule still applies: drivers must pass at a safe distance and not cut back in until clear.
The Idaho stop (stop-as-yield)
An “Idaho stop” law lets cyclists slow down and yield at a stop sign instead of coming to a full stop, then proceed if the way is clear. Idaho passed the first one in 1982. It is not a license to blow through intersections: you must still yield to anyone with the right of way.
| State | Stop signs | Red lights | Notes |
|---|---|---|---|
| Idaho (Code § 49-720) | Treat as yield | Stop, yield, then proceed with caution | Covers bikes and e-bikes at stop signs |
| Oregon (ORS 814.414) | Treat as yield, at a safe speed | Full stop required | Enacted in 2019; failing to yield is a Class D traffic violation |
| Washington (RCW 46.61.190) | Stop, or treat as yield | Full stop required | Not at railroad crossings or school bus stop signals |
| Colorado (CRS 42-4-1412.5) | Treat as yield, at 10 mph or less (cities may raise to 20 mph with signs) | Stop, yield, then go straight or turn right | Riders 15 and older, or younger with an adult; overrides conflicting local ordinances, but signs aimed at bikes must be obeyed |
A few other states have passed their own versions in recent years, with different limits. If your state is not in this table, assume a full stop is required until you confirm otherwise in the code.
Freeways and highways
Bikes may use most public roads, including many state highways and rural roads, usually on the shoulder or the right edge. Limited-access freeways and interstates are a different story: whether bikes may use the shoulder depends on the state and often on the specific stretch of road. Look for signs at the on-ramp, and check your state department of transportation for its bicycle map or rules.
For riding in town, including sidewalks and bike lanes, see sidewalk riding laws. For equipment, see bike light laws and bike helmet laws.
Frequently asked questions
Do cyclists have to ride as far right as possible?
No, as far right as practicable, which is not the same. In California and Florida, for example, you may leave the right edge to pass, to prepare for a left turn, to avoid hazards, or when the lane is too narrow for a car and a bike to share side by side.
How much room does a car have to give a cyclist?
In most states at least 3 feet (0.9 m). New Jersey and Pennsylvania require 4 feet, South Dakota 6 feet above 35 mph, and states like California, Georgia, Kentucky, Nevada, Oklahoma and Washington also require a lane change when another lane is free.
Can cyclists ride two abreast?
It depends on the state. Florida, for example, allows two abreast within a single lane when it does not impede traffic, and requires single file in a bike lane too narrow for two. Check your state code for the exact rule.
What is the Idaho stop?
A law that lets cyclists treat stop signs as yield signs, and in some states red lights as stop signs. Idaho passed it in 1982. Oregon and Washington apply it to stop signs only; Colorado covers stop signs and red lights for riders 15 and older.
Can I ride my bike on the highway?
On most public roads, yes. Limited-access freeways and interstates are a different matter: rules differ by state and even by stretch of road, so look for signs at the on-ramp and check your state department of transportation.
