The 36x30 portrait orientation matches natural reading patterns for regulations, accommodating detailed rules, multiple restrictions, and legal citations while maintaining presence comparable to horizontal guidance signs.
Vertical 36x30 signs display up to three different speed conditions (cars/trucks/night) using 6-inch numerals, or single speeds with 8-10 inch numbers visible from 500+ feet for highway applications. Check out our MUTCD speed limit signs for compliant options.
Single posts support 36x30 signs up to 0.100" thickness (approximately 15 pounds) in normal conditions, with two-post mounting required for thicker materials or wind speeds exceeding 90 mph. Proper post size is also necessary for large warning signs like hill warning signs.
QR codes minimum 4 inches square on 36x30 signs link to detailed information, translations, or real-time updates, with high-contrast placement and weather-resistant coating maintaining long-term scannability. This can be useful on custom signs, such as custom highway signs.
Vertical signs maintain readability within 30-degree cone from perpendicular, with prismatic sheeting extending to 45 degrees, and specialized wide-angle materials providing 60-degree visibility for curve approaches.
