MUTCD Be Prepared To Stop Sign CW3-4

The CW3-4 warns drivers approaching a work zone that they may need to stop ahead. Black "BE PREPARED TO STOP" legend on a fluorescent orange retroreflective background. Used under MUTCD Part 6 in advance of flagger stations, temporary signals, or lane closures where traffic may be held.

Four sizes are currently available. Gated job sites and private haul roads, where trucks may be held at a checkpoint, can use the 24" x 24". The 30" x 30" is for low-volume roads. The 36" x 36" is for conventional single and multi-lane roads. The 48" x 48" is the largest face, for wide approaches where drivers need to read the warning from farther back. Single-post mounting with two 3/8" holes at top and bottom applies to the 30" and 36" sizes.

Sign post, mounting hardware, and brackets are sold separately.
