Bicycle Crossing Sign: Meaning and What to Do

The yellow diamond with a bicycle symbol warns that bicycles regularly cross or enter the roadway ahead, at a trail crossing, a popular route, or a stretch where riders share the lane. It marks places where a cyclist may appear where car drivers do not habitually look.

The sign

Bicycle Crossing Sign

  • MUTCD W11-1
  • Diamond
  • Yellow with a black bicycle symbol
  • Warning sign

The physics ask for margin: a cyclist is narrow, quick to appear from an angle, and unprotected. Expect riders near the edge of the lane, allow for their movements around drain grates and debris, and remember that most states require several feet of clearance when passing.

What to do

What to do when you see the bicycle crossing sign

Slow down, scan the road edges and any trail mouths, and be ready to yield. Pass a cyclist only when you can leave generous room, a full lane change where possible, and do not squeeze past where the lane narrows. At night, expect a rider's light to be dimmer and closer than it looks.

The signs it is confused with

Tests contrast the yellow warning diamond with the white regulatory Bike Lane signs, which assign road space rather than warn, and with shared-lane markings painted on the pavement. Yellow warns you cyclists are likely; white tells you what part of the road is theirs.

Questions

Questions about the bicycle crossing sign

What does the bicycle warning sign mean?

Bicycles frequently cross or ride on the road ahead. Slow down, scan the edges and crossings, and be ready to yield to a rider who appears where cars do not usually look.

How much room should I leave when passing a cyclist?

As much as the road allows, at minimum the clearance your state's law names, often three feet or more, and a full lane change where one is available. If you cannot pass with that margin, wait until you can.

Is this the same as a bike lane sign?

No. This is a yellow warning diamond: cyclists likely ahead. Bike lane signs are white regulatory signs that reserve part of the roadway for bicycles and restrict when drivers may enter it.

Why do cyclists move around within the lane?

They steer around drain grates, debris, and seams that a car ignores, and wind affects them. The warning sign is telling you to expect that movement and leave room for it.

How does the bicycle sign appear on the written test?

As symbol recognition and in yielding scenarios, especially trail crossings and right turns across a rider's path. The tested answer favors the cyclist: slow, yield, pass wide.
