Speed Bump Sign W17-1

The SPEED BUMP version of the official Speed Hump sign. The 2023 MUTCD lets agencies print SPEED BUMP in place of SPEED HUMP on the W17-1 diamond (Section 2C.27), and the manual notes the public does not tell humps and bumps apart. Post it ahead of a raised bump on a city street, campus road or apartment drive so drivers slow before the wheels reach it.

Use 30" x 30" on a two-lane street and 36" x 36" where the road has more lanes, as the 2023 MUTCD size table lists. The manual also says an advisory speed plaque should go under the sign, though only the first sign in a row of bumps needs one. Sign post, mounting hardware, and brackets are sold separately.
