Standards, Manuals & Documentation
What the exam tests
The Standards, Manuals & Documentation domain checks whether you can find the controlling requirement, apply the current edition, and leave a defensible record. The MUTCD is the national standard for signs and markings; the Standard Highway Signs and Markings (SHS) book supplies official designs, sizes, and letter heights. State and local supplements, FHWA Official Rulings, and agency standard drawings add requirements but cannot make a device less safe than the MUTCD. Edition control matters: a 2009 MUTCD citation is not interchangeable with the 2023 edition without checking the current text.
Core rules
- Use the current MUTCD part: Part 2 for signs, Part 3 for markings, Part 6 for temporary traffic control.
- Design from SHS; do not scale, redraw, or substitute standard symbol signs.
- Record engineering judgment for nonstandard placement, size, or device use.
- Retain sign inventory, work orders, inspection records, material certifications, and retroreflectivity readings.
- Know the hierarchy: federal standard, state supplement, local policy, project special provision.
Worked example
A crew wants to replace a damaged STOP sign on a conventional two-lane road with a 24-inch sign because it is in stock. The technician checks MUTCD Table 2B-1 and the SHS R1-1 drawing. The minimum conventional-road size is larger than 24 inches, so the stock sign is not acceptable. The technician orders the correct size, records the deficiency and replacement date, and notes that a smaller sign would require an approved experiment or official interpretation-not a field decision.
Traps
Using an obsolete edition; treating SHS as a suggestion; missing a state supplement; documenting only that work was done, not the basis; and assuming a vendor catalog listing is an approval.
