They are required when road construction, utility work, or special events block a designated bike lane or path, directing cyclists to a safe alternate route. These are essential bicycle traffic signs for maintaining urban mobility during road improvements.
Like all temporary traffic control signs, they are Orange with Black text or symbols to signal a construction zone. This color coding is consistent with other work zone signs to ensure drivers and cyclists immediately recognize a change in the normal traffic pattern.
The M4-9 is the standard MUTCD "Bicycle Detour" sign featuring a bike symbol and the word DETOUR on an orange background. It is often used in conjunction with bike safety signs to ensure cyclists don't accidentally enter hazardous construction areas.
No, cyclists have different mobility needs. A specific "Bike Lane Closed" or "Share the Road" sign is safer than forcing bikes into general traffic without warning. Using specific lane signs for cyclists prevents confusion and reduces the risk of accidents between bikes and motor vehicles.
Since they are temporary, they are often mounted on portable A-frames, barricades, or temporary posts along the detour route. For semi-permanent detours, you can find durable mounting solutions on our street sign brackets page to ensure the signs remain stable in the wind.
Fluorescent orange reflective signs quickly and conspicuously mark bike detours. Whether the road is under repair or there is an emergency situation, bicycle detour signs quickly and clearly lead bikers to another route. Post our bright bike detour signs to ensure bikers never get lost.
