Frequently Asked Parking Sign Questions
What are the rules for reflective parking signs?
High Intensity or Diamond Grade sheeting is required for all traffic signs, while Engineer Grade is acceptable for parking signs.
How long do parking signs last?
Sign longevity varies by climate and sun exposure. Engineer Grade signs typically last at least seven years, while High Intensity and Diamond Grade signs can last over 12 years.
What liability do I have if my sign fades and is no longer reflective?
If your parking lot or road is "open to public travel," MUTCD standards apply, requiring signs to maintain specific levels of retroreflectivity similar to public highway signs. Privately maintained off-street roads are generally exempt. Installing reflective signs is a key way to reduce liability.
How deep should I install a channel post for my parking sign?
Channel posts should be driven 18" to 30" into the ground, depending on the post length and soil conditions.
Are there color restrictions on custom signs?
No, modern technology allows us to print nearly any design, size, or shape on a traffic or parking sign blank.
Can I place "Buckle Up" messages on STOP or YIELD signs?
No. MUTCD Section 2B.10 specifies that only official traffic control information should be displayed on STOP or YIELD signs to maintain their intended recognition.
Is Fluorescent Yellow Green (FYG) mandatory for pedestrian and bicycle warning signs?
FYG is required for school area traffic control signs and is optional for pedestrian and bicycle applications.
Can street name signs be installed on the same post as a STOP sign?
Yes, per MUTCD Section 2A.16, street name signs can be mounted with STOP or YIELD signs as long as they don’t detract from the STOP or YIELD message.
Is it acceptable to use all uppercase letters for street name signs?
No, street name signs must use mixed case, with the first letter in uppercase followed by lowercase letters, improving recognition and legibility.
What design is correct for school crossing signs?
The current school crossing sign design (S1-1) does not include crosswalk lines under the children’s feet, which were removed in the 2000 MUTCD update.
