Sight Distance & Vertical Curve Placement (MUTCD 2C.05)

The S3-1 "School Bus Stop Ahead" sign is mandatory when a stopped bus is hidden by a hill crest or blind curve.

  • The Hazard: If the Stopping Sight Distance (SSD) is less than required for the posted speed limit (e.g., a driver traveling 55 MPH cannot see the bus stop from 495 feet away), an advance warning sign must be installed.
  • Placement: Install the S3-1 sign before the crest of the hill or the beginning of the curve. This ensures the driver is alerted before they lose the line of sight to the bus stop.
  • Visibility: Use Fluorescent Yellow-Green sheeting to maximize contrast against rural foliage during early morning pickups.

Federal Standards for Bus Stop Signs

Installing compliant Bus Stop Signs is essential for maintaining traffic flow and pedestrian safety. Whether for a municipal transit authority or a local school district, Bus Stop Signs serve as the legal designation for pick-up and drop-off zones. Under the Manual on Uniform Traffic Control Devices (MUTCD), Bus Stop Signs must meet specific criteria for size, color, and retroreflectivity to be legally enforceable.

Types of Bus Stop Signs

We manufacture two distinct categories of Bus Stop Signs:

  • Regulatory Bus Stop Signs (R7-107): These are the rectangular "No Parking Bus Stop" signs. They legally reserve the curb space for transit vehicles, allowing police to ticket or tow cars blocking the zone.
  • Warning Bus Stop Signs (S3-1): These are the yellow or fluorescent yellow-green diamonds used to warn drivers of a "School Bus Stop Ahead." These Bus Stop Signs are critical in areas with limited sight distance (blind curves or hills).

Placement of Bus Stop Signs

To maximize effectiveness, Bus Stop Signs should be installed strategically:

  • At the Curb: Regulatory Bus Stop Signs must be placed at the beginning and end of the designated zone to prevent vehicle encroachment.
  • Advance Warning: Warning Bus Stop Signs (S3-1) must be installed 150 to 700 feet in advance of the stop. This gives drivers adequate time to slow down before encountering a stopped bus.

Reflectivity for Bus Stop Signs

Transit systems operate early in the morning and late at night. Your Bus Stop Signs must be visible 24/7.

  • High Intensity Prismatic: The standard for all regulatory Bus Stop Signs.
  • Fluorescent Yellow-Green: The mandated standard for all School Bus Stop Signs. This neon material ensures the sign is visible during the dangerous dawn/dusk commuting hours.

Frequently Asked Questions

Common questions regarding MUTCD compliance, installation standards, and material specifications for regulatory signage.
Can I install Bus Stop Signs on my property?

If you manage a private facility (like a mall or office park) with a shuttle service, you can install Bus Stop Signs to designate pick-up points. However, you cannot install official municipal Bus Stop Signs on a public street without authorization from the Transit Authority or City Public Works department.
What is the standard size for Bus Stop Signs?

  • Regulatory (No Parking): The standard size for Bus Stop Signs is 12" x 18" or 12" x 24".
  • Warning (Bus Stop Ahead): The standard size for School Bus Stop Signs is 30" x 30" or 36" x 36" for higher speed roads.
Do Bus Stop Signs require a specific post?

Yes. Bus Stop Signs should be mounted on U-Channel Posts or Square Tubular Posts that meet NCHRP-350 crashworthiness standards. Using proper hardware ensures your Bus Stop Signs remain upright in high winds and safe in the event of a vehicle collision.
