Blind Curve and Blind Corner Signs

Slow down before you reach the bend, move as far from the blind side as your lane allows, and cover the brake so you can stop fast. Don't cross the centerline or cut the corner - a hidden oncoming vehicle is exactly what the sign is warning about. On a narrow private road, a light tap of the horn can announce you before you enter the corner.

Blind corner and blind curve text signs are advisory signs, not MUTCD-numbered ones, which makes them ideal for private roads, driveways, HOAs, parking garages, and campuses. On a public road, the MUTCD way to sign a blind bend is the standard Curve (W1-2) or Turn (W1-1) warning sign, often with an advisory speed plaque. If you need federal compliance, use those; for private property, the plain-language blind corner sign communicates faster.

A blind curve sign is about visibility - you can't SEE around a single bend. A Winding Road sign (W1-5) is about quantity - it warns of three or more curves in a row. Use a blind corner sign for one obscured bend; use a winding road sign for a stretch of consecutive curves.

Install the sign on the approach, far enough ahead that a driver can slow in time - and on a fast rural or mountain road, that means posting it well back, since stopping distance grows with speed. Sign both directions of a two-way blind corner, and on a hidden driveway add a warning on the main road angled toward passing traffic. Reflective sheeting keeps it readable at night, when rural corners are hardest to judge.

Yes. Pairing a slow-down message with a speed is one of the most effective setups, since a lower speed shortens the distance a driver needs to stop. We offer custom signs that combine a blind corner warning with a specific MPH, which works well on private roads and in communities where you set the limit.

Put it on the main road at a distance before the hidden driveway, angled toward approaching traffic, so drivers know a vehicle may pull out from the obscured entrance. The Blind Driveway Ahead sign is built for this. "Hidden Entrance," "Blind Drive," and "Blind Corner" are often used interchangeably - pick the wording that matches your layout.

A convex mirror lets the person exiting the blind corner see oncoming traffic. Using both is the best setup - the sign shortens the speed, the mirror lengthens the view. Browse our road safety equipment for mirrors.

They're made of rust-proof aluminum, so they hold up to long-term outdoor exposure without fading, with Engineer, High Intensity, and Heavy-Duty grades available. For a corner that's dangerous at night, choose a reflective grade, so headlights light the sign well before the bend.

If it's a public street, report the sightline hazard to your city or county public works or traffic department, since the sign is the road authority's call. If it's a private road, driveway, or HOA, you can post an advisory blind corner sign yourself.
