Idaho maintains standard right-on-red permissions in 2026 with no major statewide changes from prior years.
Core Rule
Drivers facing a steady circular red light must come to a complete stop before turning right, then proceed if the intersection is clear of oncoming traffic, pedestrians, and cyclists—unless a sign prohibits it.
This aligns with Idaho Code § 49-802, requiring a full stop at the limit line, crosswalk, or intersection entry.
Red arrows override this: no right turn permitted until green. Yield right-of-way always; failure risks tickets or liability.
Left Turn Allowance
Unique to Idaho and select states: after stopping at a circular red (not arrow), drivers may turn left onto a one-way street flowing in the turn’s direction, if no prohibiting signs exist. Two-way streets block left-on-red.
2026 Enforcement Notes
No 2026 legislative updates alter right-on-red basics, per recent analyses—focus remains on compliance amid rising pedestrian safety pushes.
Local signs (permanent or lighted) ban turns at high-risk spots like school zones. Idaho Stop applies only to cyclists, treating stops as yields.
Violations are infractions: $50–$100 fines, possible points on license.
| Signal Type | Right Turn | Left Turn | Key Condition |
|---|---|---|---|
| Circular Red | Yes, after stop | Onto one-way only | No signs, yield all |
| Red Arrow | No | No | Wait for green |
| With Pedestrians | No | No | Yield priority |
| Prohibited Sign | No | No | Obey posted |
Safety Tips
Scan mirrors, crosswalks, and sidewalks twice—Boise PD stresses caution on busy arterials like Fairview Avenue. Cameras at intersections enforce stops nationwide, including Idaho cities. In winter, ice demands extra braking distance.
Right-on-red boosts flow but spikes side-impact crashes; hesitate if unsure.
