The viewing distances listed in this chart reflect the viewing distance for each of the sizes. The Manual of Uniform Traffic Control Devices (MUTCD) does not provide specifics regarding the use of certain text heights at certain distances in order to improve legibility. Instead, the MUTCD has already determined all of the necessary text sizes and merely provides the specifications for various sizes of signs, which in turn all have specific use cases that must be followed in order to help keep drivers safe and aware of important regulations.
It is the responsibility of the end user to follow the guidelines and requirements of the Manual of Uniform Traffic Control Devices (MUTCD) in order to provide road users with signs that ensure optimal legibility.

This Stop Ahead Sign is printed to the substrate with the latest digital printing practices, which reduce set-up times and allows SafetySign.com to ship out faster than competitors. These advanced printing processes also eliminate set-up charges and order minimums. At SafetySign.com, we print your text and graphics with UV inks directly to the substrate. Your traffic sign text and graphics won't peel, unlike a Stop Ahead Sign from companies that laminate graphics over the sign material.
Printing Methods
Cross-Hatch Ink Adhesion Test
SafetySign.com’s advanced printing process undergoes a stringent cross-hatching test. This specifically tests the adhesion and resistance to separation of the inks from the sign. In testing, a sample from the printing process is scored and covered in adhesive tape. The tape is removed and the sample assessed for adhesion quality.
We use a three-stage process to test all of our printing processes. We print our signs using only the processes that pass all three stages, giving you the highest quality signage possible.
